6.4.3. MGI VideoWave Works to continue 1.Introduction Multimedia at home and school is being more and more popular. Some of us who has VHS Camcorder and want produce (edit) own movie or only systemize existing videos has to use minimum two conventional VHS recorders. This kind of “linear” editing is very time consuming and complicated and results could be not very satisfied.For some years ago high quality video film production was possible only in big professional studios. But during the last tree year’s situation is changed. Digital cameras and high-speed computers together with “non-linear” editing programs are being more popular not only for professional’s producers but also at home.Home production of video movies has to be easy non-expensive and robust. Lower cost, higher-quality video capture can be accessible to everyone, not just professionals. Some of us have already at home many of multimedia components such as: TV receivers, VHS recorders, PC and DVD players or Digital Camcorders (fig 1.1)



Fig.1.1. All these components can be connected and can work together with use of our Digital Home Video Studio solution 2.Criteria for Multimedia equipment at home



- Installation of multimedia software and hardware at home has to be easy. - Equipment has to be robust for users errors like wrong cable directions (bi-directional) - User interface has to be ease to learn and manuals have be easy written ( no shortcuts).

- Non-expensive software and hardware upgrading on different platforms such Mac,PC- Good quality of final product such as; VHS video, CD, DVD or WEB presentations

We might consider at most part of equipment already exit at home or at school and should be used to Video Studio with no significant costs and changing. Actually this equipment can have not enough processing and storage capacity for multimedia purpose specially for editing of movies. Upgrading has to be cost-effective and relatively easy. We can’t change processor speed but we can expand hard discs and RAM capacity. Price of today’s 7000-rpm 50GB disc is under 2000 NOK and is enough to storage over 1 hour compressed video data. Relatively low costs RAM extension can significant change multimedia-processing speed. It is recommended to use graphical card with composite TV input-output capability than we can use part of our PC display as TV screen.Some high schools through educational agreement with Apple Computers are equipment with Apple computers and these computers should work together in our Home Studio with Microsoft Windows based PC’s. Equipment has to be robust for users errors. It can be possible that unqualified consumer can connect cables in wrong directions so it means connections has to be bi-directional. This problem can be solved by use IEEE 1394 based connection interface that is also compatible with different Operating systems like MacOS, Microsoft windows or Linux. 3. Fire Wire (IEEE1394 Standard) and why we chose it to Digital Video Home Studio Fire Wire is one of the fastest peripheral standards ever developed. Transferring data at up to 400Mbps, Fire Wire delivers more than 30 times the bandwidth of the popular USB peripheral standard. With its high data-transfer speed and “hot plug-and-play” capability, Fire Wire is the interface of choice for today’s digital audio and video devices, as well as external hard drives and other high-speed peripherals.Apple invented FireWire in the mid-90s and shepherded it to become the established cross-platform industry standard IEEE 1394. FireWire is a high-speed serial input/output technology for connecting digital devices such as digital camcorders and cameras to desktop and portable computers. Widely adopted by digital peripheral companies such as Sony, Canon, JVC and Kodak. Fire Wire has become the established industry standard for both consumers and professionals.The FireWire advantage can be summed up in three words: speed, speed, and more speed—at 400Mbps, it has more than 30



times the bandwidth of USB, which makes it the perfect choice for high-speed storage and serious video capture. Here are some other benefits;-Supports up to 63 devices using cable lengths up to 14 feet Hot-pluggable—you don’t have to turn off a camera or another drive to connect or disconnect it, and you don’t need to restart

your computer. Fire Wire cables are snaps to connect—you don’t need device IDs, jumpers, DIP-switches, screws, latches or terminators such as SCSI or IDE standards.

3.1. IEEE 1394 - Interface for the Digital Network Before we continue to describe network implementation of IEEE 1394 in our Digital Home Video Studio I want answer for some basic questions. What is IEEE 1394? IEEE 1394 was conceived by Apple Computer and then developed within the IEEE 1394 Working Group. The IEEE 1394 standard is a scalable, flexible, easy to use, low-cost digital interface that will integrate the worlds of consumer electronics and personal computers. The IEEE 1394 standard defines both a backplane physical layer and a point-to-point cable-connected virtual bus implementations. The backplane version operates at 12.5, 25 or 50 Mbits/sec. The cable version supports data rates of 100, 200 and 400 Mbits/ sec. Both versions are compatible at the link layer and above. The Standard defines the media, topology, and the protocol. The balance of this document will focus on the implementation and advantages of the cable version of this interface What is FireWire?

FireWire is Apple's implementation of IEEE 1394. FireWire is:

● A digital interface - no need to convert digital data into analog for better signal integrity ● A physically small thin serial cable - replaces today's bulky and expensive interfaces ● Easy to use - no need for terminators, device IDs, screws, or complicated set-ups ● Hot plug gable - devices can be added and removed while the bus is active ● Scalable - the Standard defines 100, 200, and 400 Mbps devices and can support the multiple speeds on a single bus ● Flexible - the Standard supports freeform daisy chaining and branching for peer-to-peer implementations



● Fast, guaranteed bandwidth - the Standard supports guaranteed delivery of time critical data which enables smaller buffers (lower cost)

FireWire supports two types of data transfer: asynchronous and isochronous. For traditional computer memory-mapped, load and store applications, asynchronous transfer is appropriate and adequate. One of FireWire's key features is its support of isochronous data channels. Isochronous data transfer provides guaranteed data transport at a pre-determined rate. This is especially important for multimedia applications where uninterrupted transport of time-critical data and just-in-time delivery reduce the need for costly buffering.

This leads to perhaps one of the most important uses of FireWire as the digital interface for consumer electronics and AV peripherals. FireWire is a peer-to-peer interface. This allows dubbing from one camcorder to another without a computer. It also allows multiple computers to share a given peripheral without any special support in the peripheral or the computers. FireWire has become the digital interface of choice and its acceptance is growing.

Why another Bus?

Today when you "surf the web" for information and click on a "hot link" you must wait for the bit-mapped date to download. Imagine, selecting an icon and almost immediately that image is on your screen. FireWire is one of the technologies that will help make this future a reality.

Several key trends and requirements are emerging:

● Consumer electronics and computers are converging. ● There is a desire to keep data digital for as long as possible as a means to reduce system cost, complexity, and improve

signal integrity. ● With the emergence of multimedia market, more and more data is video and audio. The ability to work with time sensitive

data is growing in importance. ● Miniaturization is continuing. Small products are favoured for portability, convenience, and material usage resources. ● Consumers are beginning to purchase computers the way they choose consumer electronics. Their criteria are: reliability,

convenience, and simplicity. ● The need and desire for Peer-to-Peer computing is growing. The master-slave model is changing as computing becomes

distributed. file:///D|/Documents%20and%20Settings/orle.TELEMEDIA10.004/My%20Documents/HomeDigital.htm (8 of 52) [06.02.2002 12:09:14]


FireWire meets these trends and requirements. FireWire provides a high performance, easy to use, real-time, interoperable (industry standard), multimaster solution to meet the needs of not only today's markets but also tomorrow's.

Initially, FireWire will be the computer attachment of digital cameras and digital video applications. The Digital VCR Conference (DVC) has accepted IEEE 1394 as the standard digital interface. The European Digital Video Broadcasters (DVB) has endorsed IEEE 1394 as their digital television interface as well. The VESA (Video Experts Standards Association) is evaluating IEEE 1394 for the digital home network media.

In the world of video editing, FireWire enabled cameras remove the need for costly analog video computer frame buffers to capture digital video. FireWire will gradually improve upon existing interfaces such as SCSI. FireWire provides higher speed, lower cost, and does more users friendly than most exist interfaces. SCSI products such as scanners, CD ROMs, disk drives, and printers are already evaluating when they will move to FireWire.

FireWire has the bandwidth capacity to replace and consolidate most other peripheral connection communication methods in use today. Hot plugging, power sourcing, and dynamic reconfiguration make FireWire a user-friendly alternative to todays interconnects. These features will allow "plugging in" of computer peripherals as easily as plugging in a home appliance.

FireWire promises to revolutionize the transport of digital data for computers and for professional and consumer electronics products. By providing an inexpensive, high-speed method of interconnecting digital devices, Fire Wire is truly the versatile I/O connection. Its scalable architecture and flexible peer-to-peer topology make FireWire ideal for connecting audio, video, and computer devices. Its isochronous support allows low cost implementations of multimedia interfaces. Every month more digital electronics products are entering the market. These products will continue to evolve and FireWire will be evolving with them.IEEE 1394 New Standards In the future, IEEE 1394 may become the basis of home networking and a replacement for PCI and IDE buses in personal computers. Currently there are several groups actively discussing extensions to IEEE 1394, including the IEEE 1394a and 1394b working groups. SonyApple, Intel, IBM are taking an active role in these standards activities and is committed to creating a broad spectrum of IEEE 1394-based products What is 1394b, and when will it be available?

1394b is a significant enhancement to the basic 1394 specification that enables speed increases to 3.2 Gigabits/sec, supports distances of 100 meters on UTP-5, plastic optical fiber and glass optical fiber and significantly reduces latency times by using



arbitration pipelining. It is fully backwards compatible with the current 1394-1995 and 1394a specifications. 1394b is an important step forward in increasing the performance and simplifying the implementation of 1394 on PC's, and, with its long-haul capabilities, makes 1394 the convergence bus between PC products, CE systems and home networking. The committee completed its work and voted to send the final draft to sponsor ballot at its meeting in Rennes, France, in October 1999, and the final spec is expected to be approved by the IEEE before the end of 2000. www.zayante.com/p1394b

Does the 1394 bus compete with USB?

Almost everyone who works with these various buses considers 1394 a complement to USB, since it offers much higher speeds (up to 1.2 Gigabit) and is designed for isochronous and asynch video/audio/data transfer. While USB is ideal for computer peripherals at speeds in the neighborhood of 12 Mbps, 1394 has a different mission. Many new PCs now include ports for both of these standards.

4.Digital Home Video Studio NetTo our Digital Home Video project we build prototype of network based on IEEE 1394 standard. To design of Digital Video Home Studio Net I considered two small computer network concepts; one based on standard Microsoft Home (Small) Office Network and second FireNet from Unibrain. There are many benefits to use Home Network based on FireNet from Unibrain against Microsoft Small Computer Network

No new interface to learnFireNet uses the existing, familiar interfaces on Windows and Macintosh platforms in such a way that users who are already familiar with the environment proceed as if nothing has changed. Supports all of the built-in networking capabilities on both Mac's and PC's. Users can share files, printers, scanners, hard disk drives, and use the network security system and any other supported network facilities.High performance - Low costRunning at 400Mbps FireWireNet provides an up to four times performance improvement over 100BaseT fast Ethernet. With FireNet, users do NOT have to purchase, install, and configure network cards (as long as they have a firewire port available) in their workstations. As a result they end up saving time and money. Further, no hubs of any sort are necessary.Broad supportUndoubtedly, Firewire (IEEE-1394, i.Link) is the serial link of the future. Major manufacturers like Apple, Sony, Compaq, Gateway, Dell, HP, etc. have already built in a firewire port in their consumer or PC products. It is estimated that by the year 2001 more than 70,000,000 units of PC and peripheral units will adopt the firewire technology.ConnectivityTo extend the network topology, I suggest using a FireWire repeaters which are available in three port configurations. Studio Net will connect up to 63 nodes together, in a tree topology spread over 25 m.Firenet can coexist with EthernetStudio Net can be installed in an existing Ethernet infrastructure without a problem. Simply install the FireNet software in a server which has both an Ethernet adapter and a 1394 port and which will play the role of the bridging device that will connect the two segments of the LAN, thus creating a single logical



network. The IEEE 1394 segment can be used for high speed/load connections without affecting the Ethernet segment speed.

SimplicityFireNet is an ideal network for laptop to desktop connections. The user can easily plug the PC laptop (or PowerBook) into the network, simply connecting it into any available Firewire port. With no special operations, instant updates, and file sharing from any computer in the network become availableCapabilitiesFireNet does NOT use hubs, or routers. It does not require complicated cabling, and does not require complex installations. On the firewire bus you may also connect any IEEE-1394 multimedia devices (such as DV cameras, firewire hard disk drives, IEEE-1394 enabled scanners, etc.) without affecting the stability of the network, and operate them directly from any workstation on the network busOS Support FireNet is a full Ethernet emulation network and works seamlessly with all existing Ethernet-compatible software and hardware. FireNet supports all of the standard Ethernet protocols, including IPX/SPX, NetBEUI, TCP/IP, and AppleTalk. FireNet is a cross-platform networking solution, meaning that it supports both Windows and Macintosh OS, operating smoothly regardless of the platform(s) in use. Of course, mixed (PC and MAC) etworks are fully supported:

5. IEEE 1394 components used in Digital Video Home Studio

5.1.IEEE 1394 CablesTo make high-speed serial interfaces easy to use, the IEEE 1394 standard adopts an extremely simple cable with a flexible structure. Using this cable, the wide connectors and multi-conductor cables that are now standard in personal computer interfaces are no longer required (Figures 3.1 and 3.2).

4-pin Cable



6-pin Cable Figures 5.1 & 5.2 IEEE 1394 Connector Styles

Data transfers handled by a shielded double twisted pair cable that is driven by low-amplitude differential signals (Figure 5.4). During data transfer, a clock signal is generated automatically by converting the data into two signals: the data itself and a strobe signal that supplements the data (Figure 5.4). This eliminates the need for the high-speed phase lock loop (PLL) circuits required by other interfaces at both the transmit and receive sides of the communications channel. As a result, systems can be constructed inexpensively. In addition, since the interface includes a power line in the cable, power can be supplied directly to low-power devices.

5.2.FireWire 3 Ports RepeaterIn our project distance between server and clients such as PC or cameras was over10 m and required some repeaters to regenerate signals. We used datafab repeater, which also can be used as Fire wire Hubs. Totally we got up to 30 m.

5.3. IEEE 1394 interfaces tested in Digital Video Home Studio project In my project I tested two main type IEEE 1394 interfaces; Lynx and OHCI industrial standards. Lynx / OHCI what are the differences – and how do I choose?

Now produces two different host PCI adapters for use with an IEEE-1394 bus. Both are capable of 400Mbps speed and have full 1394 capability, but they are, nevertheless, quite different. As you may know, the typical IEEE-1394 interface consists of two integrated circuits (as well as a number of passives to support them): the PHY or Physical Layer chip, and the LINK or transaction layer chip. While there has been considerable standardization in PHYs over the last few years, LINKs with very different philosophies continue to be manufactured. The Fireboard400 described under is based on the TI TSB12LV21b LynxB LINK while the Fireboard400-OHCI Open Host Controller Interface is based on the TI TSB12LV23/26 OHCI LINK. To simplify, the OHCI is easier to program, does more automatically, and is supported as a standard LINK by Microsoft under W98SE and W2000 (but not under WinNT). The LynxB is far more flexible and is capable of greater total throughput. It is supported by Unibrain under WinNT, W95, W98, W98SE and W2000. It is however; more difficult to program and is not supported with integrated drivers by Microsoft

DV –VHS recorder plays in our project a role of interface between old analog formats and new digital (DV) world. There are four most important analog IN/OUT connections.

● Component Video● Divides the video signal into three elements: luminance, which represents brightness in the image, and separate red and blue

signals (expressed as either Y R-Y B-Y or Y Pb Pr). Component video is superior to both composite and S-video the image, and separate red and blue signals (expressed as either Y R-Y B-Y or Y Pb Pr). Component video is superior to both composite and S-video because it provides improved color purity, superior color detail, and reduces NTSC artifacts. This is a three-connector output from a video source (such as a DVD player), or input on a Television. Each signal is supplied on a separate colored RCA cable for easy connection.



● ● S-Video● S-Video keeps luminance (Y) (black and white) and chrominance (C) (color) signals separate to take full advantage of high

resolution sources like: DBS satellite, DVD & S-VHS. Better than a composite video connection, not as good as component.

● ● S-Video Out● S-Video keeps luminance (Y) (black and white) and chrominance (C) (color) signals separate to take full advantage of high

resolution sources like: DBS satellite, DVD & S-VHS. Better than a composite video connection, not as good as component.

● ● Component Video Output● Divides the video signal into three elements: luminance, which represents brightness in the image, and separate red and blue

signals (expressed as either Y R-Y B-Y or Y Pb Pr). Component video is superior to both composite and S-video because it provides improved color purity, superior color detail, and reduces NTSC artifacts. This is a three-connector output from a video source (such as a DVD player), or input on a Television. Each signal is supplied on a separate colored RCA cable for easy connection.

● 5.6. DV standard and why I chose it to Digital Home Video The preferred way with DV is to dispense with the external cabling and headaches altogether and use device control implemented via Fire Wire. DV over Fire wire carries video, audio and device control signals, all through the same medium. No extra cables. All that's needed is the proper drivers. Their implementation may be different across the boards. For a long time, there was no real device control standard specified in DV, so manufacturers could (and did) pretty much roll their own protocols.

High quality: With analog video, noise can enter at any point of the path. And usually, once noise has entered, noise will stay. There's tape noise. The cable that routes the video to the capture card can pick up noise. The capture card usually picks up a lot of noise, because it sits in a very noisy environment: In the computer. Going back out to tape adds noise yet again.

Noise doesn't just degrade the picture; it also degrades the compression process. Because a codec treats noise as information, it dutifully stores the noise. Which results in high data rates. Those of use who survived the years of analog video on the computer got used to thinking that anything better than 5 Megabytes/second or less than 4-x compression is good. This is true in most of



the cases, but not all. Those of us lucky enough to own very high quality equipment quickly realized: A very clean video signal actually lends itself better to compression. It can compress more; it can tolerate a lower data rate and still look better. Why? Because it was free of noise in the first place. By compressing the video at the point of origin (in the camcorder, behind the lens), DV avoids noise altogether.

High performance: Analog video usually compresses at a varying rate. If the content is complicated, the data rate goes up. Owners of Adobe Premiere can actually watch this process by using a feature called Movie Analysis. It usually shows spikes in the data rate during complicated scenes, such as transitions. These spikes can lead to data stalls on playback. The video zips along nicely, suddenly a spike comes down the pike, spike exceeds the bandwidth of the computer and bang playback hangs.

DV uses a steady rate of around 3.7 Megabyte/second. This is a no-brainer for a moderately fast system with a decent hard drive. There are no spikes in the data stream, ergo any bumps in the road to good playback.

Low cost: A good capture board can be an expensive thing, and some of use have amassed quite a collection over the years. As new ones emerge, driver support for the old ones dries up. Will it ever end? Yes: Let's forget about capture boards altogether. With DV, capture and compression happens right behind the lens..

6. Non-Linear Video Editing

DV Editing: Finally, real digital video all the way. With analog video, video had to enter and exit the computer in analog. But the computer is digital. Actually, to the computer, working with analog video is an act against nature.

For a long time, the computer resisted against processing analog video. The computer sabotaged capturing video by dropping frames at undue times. After capture was solved with heavy hardware, the computer resorted to random work stoppages during



playback. Some people actually claim that analog capture boards employ sophisticated pressure sensors, which interrupt playback when a tight deadline is sensed. We've learned to live with that. But we don't need to anymore. Because with DV, video editing finally is digital end-to-end. The computer likes that.

Things you'll need. (You probably already have most of them.) You need a DV camcorder or DVCR equipped with Firewire (IEEE 1394). All DV machines sold by Sony and other vendors have the Firewire connector, many DV machines sold by other vendors don't (although many are entering the market as we write.).

You need a Firewire interface board. Ever since Sony released their first DV machines in late 1995, people have clamoured for these boards. Now, they are finally here. Adaptec/DPS, Fast, miro, Matrox, Radius have announced or are already shipping boards which allow your DV camcorder or DVCR to connect to your computer via Fire Wire.

You need a non-linear editing application such as Adobe Premiere Avid Express. Many boards, such as the, come with a version of Premiere. Some boards come with a light or "LE" version (which you can later upgrade), some like the Spark come with a full version.

You need a suitably powered computer with lots of hard drive space. Keep in mind: DV creates 3.6 to 3.7 Megabytes of data per second. One minute, 222 Megabytes. 10 Minutes: 2.2 Gigabytes. A 90 minute, feature-length movie would fill 20 Gigabytes of hard drive space in final edited form. Also keep in mind that currently shipping Firewire solutions (or rather the drivers that come with them) don't allow to "Print to DV" from the Premiere timeline. Allow sufficient space for a target file for the "Make Movie" process. This is likely to change with future drivers, changes to the operating system or the editing application.

Your drive needs to be fast enough to cope with the steady stream of 3.7 Megabytes per second You should be fine with a good SCSI drive that spins at 7200 rpm. Stay away from IDE drives. They put a heavy load on the CPU. With DV, the CPU must be able to do some processing during data transfers.

Now, let's go over the editing process step-by-step

6.1. DV & Fire wire Editing Workflow Step 1: Compression in camera. As video is being shot, it is compressed and converted to digital form in the camcorder. What used to be "video" now sits on a digital tape. This digital tape can be played in a digital tape drive, such as the one in your camcorder, in a DVCR, or in a standalone unit.

Step 2: A transfer DV data, not video, is transferred electronically via the Fire Wire to the computer's hard disk. This not a capture process it's a file copy process. A driver camouflaged as a regular capture driver, or by a standalone utility can handle the copy process. This is specific to the individual implementation of the driver for the various DV/Fire Wire boards, and it can also change as matter progress. The hard drive has to be fast enough to cope with the 3.7 Mbytes/sec data rate (plus some overhead). Theoretically, it is possible to stop the tape and restart if and when the hard drives can't cope with the data rate, but this is an involved process and may not be implemented in early versions of DV drivers.

Step 3: You want it wrapped? During the copy process, the DV data is "wrapped" into a file format commonly understood by computers, in this case either AVI for Video for Windows or QuickTime for the Mac. Both file formats allow for "installable compressors," also known as codecs. AVI for instance can work with a multitude of installable compressors, such as Indeo, Cinepack, VDO, etc. to name just a few. The compressed DV data is treated like data produced by just another installable compressor. As a matter of fact, there is a DV compressor/decompressor (codec) installed on your system. But during the file copy process, this codec is not needed. I’ll cover that later in more detail.

Step 4: After the copy process has been finished, the DV data is sitting on your hard drive, wrapped into a file format any standard editing application can process. Note: The actual DV data has not changed. It hasn't been touched by a codec, it hasn't been recompressed, changed or altered.

Step 5: DV Editing. To edit your clips, you use any standard editing application that can work with industry standard file formats, such as the Adobe Premiere , Avid X-pressDV, Microsoft Movie Maker or MGI Video Wave. I'll cover that later in more detail.

Step 6: During editing with a program like Premiere, your DV AVI or QuickTime movie will behave just like any other video clips you used before.

Step 7: When, and only where Premiere adds filters or transitions, Premiere needs the DV data in uncompressed form. For this, Premiere will call the installed DV codec. Premiere will hand it compressed frames retrieved from the AVI or QT file. Premiere receives uncompressed RGB bitmaps back from the codec. Premiere then blends, filters, combines, warps or alters these frames



according to the specified transition. When done, Premiere hands the finished RGB bitmap to the installed DV codec. The codec compresses the bitmap to DV AVI or QT and hands it back to Premiere. Premiere then stores it in the target file. The installed DV codec can be implemented in hardware or in software. Read more about this interesting issue here.

Step 8: Clips without filters or transitions are not being touched by the codec and simply copied to the target file. If you would have a project, which consists only of hard cuts, the codec wouldn't be called for editing at all.

Step 9: Here we go again. After all edits have been finished, the resulting file must be copied from the computer to the DV device via Fire Wire. During this copying process, the AVI or QT wrapper is removed; data specific to the receiving device is adjusted or restored. This is usually done "on the fly" as data is sent to the DV device. Some boards may need additional post processing. The copy process usually is handled by a standalone utility, or by a Premiere "Print to DV" plug in.

Step 10: You are done! On your hard drive sits DV video, most of it as pristine as you've shot it. No generation loss. You've reached the holy grail of video editing. Right on your computer.

6.2. Non-linear DV editing software tested for Digital Video Home Studio

Today’s software marked for video film editing is dominated of two groups of software: professional high quality relatively expensive programs and freeware programs. In these two groups I choose some basic criteria for using in Home Digital Video Studio.

1.Installation has to be easy and robust

2.It has tolerated some inexperience users (no data experts).

3.Software has to be compatible with different operating systems such MS Windows,

MacOS or Linux.

4. Programs has to have user friendly interface



5. System requirements -no expensive hardware required

6. DV editing results (export files- film sequences) and input (import files- capture sequences) has to be compatible with most existing formats.

The same computer worked excellent with Adobe Premiere 6.0 software.

6.3.2. Adobe Premiere 6.0



Fig.6.2.2.User interface for Adobe Premiere 6.0DV functionalityAdobe Premiere 6.0 provides direct support for IEEE 1394 (Fire Wire/ I. Link) on both Windows and Mac OS. Using only the DV port on your hard drive, an IEEE 1394 connection, and your DV camcorder, you get perfect digital video in premiere every time. Premiere offers built-in support for all types of DV devices, ranging from consumer to professional. By simply connecting a DV device to the IEEE 1394 port on a Windows or Macintosh computer, you can capture DV clips and begin editing right away. On a computer with an IEEE 1394 port, there's no need to install additional hardware such as a video capture card. Just select the appropriate DV device manufacturer and model in the Device Control dialog box, and Adobe Premiere assigns the video input settings appropriate to that device, making the video capture process more precise.

DV capture Settings tab, you can view and edit video capture settings, change the capture location, and set device control preferences. Using the Logging tab, you can quickly log video clips, set In and Out points, name clips and reels, effortlessly batch-capture multiple logged video clips, and add comments about each clip. The Movie Capture window in Adobe® Premiere® now includes a Settings tab and a Logging tab. Using theWeb export plug-ins for one-step Web outputAdobe Premiere 6.0 includes three plug-ins (automatically installed) for exporting an individual clip, a segment of the Timeline, or the entire program to a Web-optimised file format. When you have finished editing your video program, select one of the following Web export options: Save for Web, Advanced Real Media Export, or Windows Media Export (Windows only).



Choosing one of these options opens the respective plug-in dialog box, in which you can specify your exported file format information.

• The Save for Web menu command exports the Timeline directly into a special version of Terran Interactive's Media Cleaner software, customized especially for Premiere.• With Advanced Windows Media Export, you can take advantage of a wide range of formatting options for the most precise output control in the Windows Media format.

Hardware compatibility

Capture and output of video in Adobe Premiere 6.0 requires either an Adobe-certified third-party capture card or an IEEE 1394 interface (FireWire or iLink) compatible with either DirectX (Windows) or QuickTime (Mac OS).

For a third-party capture card to be deemed Adobe-certified, Adobe Premiere Quality Engineering must test and approve the card for use with a specific version of Premiere using specific versions of driver software created by the card manufacturer.

Because built-in DV support in Premiere 6.0 is implemented through DirectX or QuickTime, Premiere requires either a Microsoft DirectX-compatible or Apple QuickTime-compatible IEEE 1394 interface. An IEEE 1394 interface is built-in to many computers and is also available separately as an add-on card such as Pinnacle DC1000 or.

6.4.2. Microsoft Movie Maker

● Microsoft Movie Maker is a part of Windows ME and Windows XP operating systems and is easiest to learn of all tested



video-editing programs. ● Fig 6.3.2 User-friendly interface of Microsoft Video Maker. ● This interface principle is similar to many other consumer products tested in our Diigital Video Home project. How easy is

to use this programs we explain under. ● ● The workspace for editing runs along the bottom of your screen, below the collections area and the monitor. This is where

you create and edit your project, which can later be saved as a movie. The workspace has two different views: the storyboard view and the timeline view. Both are used in editing. The storyboard view lets you sequence your clips, while the timeline view lets you refine the way the clips interact with each other and with an audio track. Toggle back and forth between the two views using the small button to the left of your workspace.

●

The storyboard view is the default view for the workspace.

●



With the storyboard, you combine your clips to tell your story. Drag clips from the collections area and drop them onto the storyboard in the order you would like them to appear in your movie. To rearrange your clips, just drag and drop them to a different location on the storyboard.

To remove a clip from the storyboard

1. Click the clip on the storyboard. 2. On the menu bar, click Edit, and then click Delete.

After you have assembled your clips, you can preview your project in the monitor. Here's how.

To preview your project in the monitor

§ Click an empty area in the workspace, and then click the Play button.

Now you can start to get a sense of how the various clips work together, and where some of the shots may be too long or may require a better transition than the simple "cut" that you get from storyboard sequencing. That kind of refining, along with the work of adding an audio track, is done in the timeline view.

Using the Timeline View

In the timeline view, the numbers that run across the top of the workspace indicate the duration of each clip. The timeline view also shows you how clips interact with each other and with the audio track, which is indicated by the bottom bar in the workspace. The Zoom In and Zoom Out buttons to the left of the workspace show you a more detailed view of how your clips are working together, and can give you a broader perspective of the entire project.

You can also create more attractive transitions in the timeline view. It’s easy to create a cross-fade (also called a "lap dissolve") in which one scene fades out while the next scene appears behind it and grows clearer as the first one dims.

Another feature of the timeline view is the Record Narration button, which lets you add an audio track keyed exactly to the clip sequence. You can watch the movie you’ve created while you narrate it.

You can insert other audio clips into your project in the same way you insert video clips and still images. Audio clips can also be overlapped, though a cross-fade transition is not created. Instead, the length of time the two audio clips play together is



determined by the amount of overlap between them. Keeping your clips organized in the Collections area on the left-hand side of Windows Movie Maker makes it easier and more fun to edit your movie. To organize your clips in folders and subfolders. Drag everything you want to include in a movie—video footage, audio tracks, still images, and more—into the collection .You can further organize your material by creating subfolders within a collection. For example, you may want to organize your clips by thematic materials, such as vacation pictures or footage of your children. Or you may want to keep everything for a larger project in one folder, and create subfolders that map to the pieces of that project.

Windows Movie Maker lets you include in your movie existing photos, audio clips, or other video files that you have stored on your computer. You can import many different file types, including:

§ Video files with an .asf, .avi, or .wmv file extension. § Movie files with an .mpeg, .mpg, .m1v, .mp2, .mpa, or .mpe file extension. § Audio files with a .wav, .snd, .au, .aif, .aifc, .aiff, .wma, or .mp3 file extension. § Windows Media-based files with an .asf, .wm, .wma, or .wmv file extension. § Still images with a .bmp, .jpg, .jpeg, .jpe, .jfif, .gif, or .dib file extension. § Microsoft PowerPoint files and individual slides with a .ppt extension.

System requirements

Windows Movie Maker requires the following minimum system configuration:

● 300 megahertz (MHz) Pentium II or equivalent ● 64 megabytes (MB) of RAM ● 2 gigabytes (GB) of free hard disk space ● An audio capture device ● A video capture device ● An Internet connection and an e-mail program (required for sending a movie to a Web server or in an e-mail message) ● IEEE 1394 DV capture card (for true DV capture from a DV device)

The following items are recommended for recording from a DV device:

● 600 MHz Pentium III or equivalent (or higher) ● 128 MB of RAM

6.4.3.MGI VideoWave



Fig.6.3.3.Users interface for MGI VideoWave Procedure how to produce a video is very similar to Microsoft Movie Maker describedabove but MGI offers additional functionalities such as; SmartDV, detect many different IEEE1394 interfaces, has rich library of transitions and special effects which were availibe only with more expensive professionals editing programs. SmarDV: If you are producing to a DV file from DV source material, MGI VideoWave III employs SmartDV, which can greatly reduce the time required to produce the final video. With SmartDV, VideoWave III can produce the DV file directly without re-rendering the frames provided the DV file has not had any effects or transitions applied. Without SmartDV, each frame that is produced must be re-rendered, even if no effects, such as text or special effects, have been added. With SmartDV, re-rendering does not take place in sections of DV footage that do not contain applied effects. Under these conditions, much faster production will result.



Easily CaptureQuickly transfer video from digital or analog camcorders, TV, VCR, Web cam, or even the Internet. Tell Your Story The unique StoryLine approach provides a visual layout of your work in progress. Use it to quickly arrange scenes, insert transitions, edit clips, add titles, apply effects, and more! Edit With Power Add fast or slow motion effects with Time Warp. Create picture-in-picture with VideoWave's Video Mixer or chroma key to seamlessly blend clips. Add titles and credits complete with motion and animation with the Text Animator. Use the Cutting Room to trim clips or use the powerful touchup tools in the DarkRoom. Spice It Up Swirl, ripple, and fade scenes. Choose from dozens of transitions, animations, and title effects. Bring your video productions to life by adding narration, music, and, sound effects. VideoWave's filters help you create stunning sepia, black and white, mosaic, or selenium clips with the click of a button.Fast ProductionOnce your video is complete, special Produce templates guide you through turning your video into the appropriate format for sending to the Web, viewing on your PC, or going out to videotape.Fast RenderingNo more waiting for your entire video file to render. The exclusive SmartDV™ feature renders only the frames that have changed.Comprehensive File SupportVideoWave supports AVI, MPEG-1, MPEG-2, Windows Media™, RealVideo®, DV, MP3, WAV, BMP, TIFF, or JPEG files.

MGI VideoWave and Mac OS X

With the release of Mac OS X, Apple has provided a technology called Classic mode. Classic mode allows you to transition to Mac OS X and extend your ability to use Mac OS 9 compatible applications; MGI is committed to supporting Mac OS X in future product releases. Although testing is in process and updates may become available, not all current Macintosh applications are fully tested or approved for operation under Mac OS X Classic mode. For this reason, no technical support will be extended to users running MGI's products that have not been approved for operation under Mac OS X Classic mode.MGI VideoWave full version comes together with the most IEEE 1394 OHCI interfaces priced under 1000 NKR or can be copied as FreeWare from internet.
