Topics
• Image Magnification (IMAG)• Recording for Distribution• Internet Streaming• Multisite campuses
Reasons To Invest In Video
Resolution • Most decent cameras today are HD• If you are projecting 720p, you don’t necessarily need
1080i or 1080p cameras• But you can always bring down the resolution cleanly, but
scaling up isn’t always clean.
What to look for in a camera
Optical Zoom • Ignore digital zoom• How far is your camera going to be from the stage?• How tight do you want to be able to zoom?
Genlock• When multiple cameras are used live, use genlock if at all
possible to avoid latency
What to look for in a camera
Image Sensor• Avoid single chip, look for 3CMOS, 3MOS or 3CCD• CMOS sensors are cheaper, less power intensive, found in
smaller and cheaper handheld cameras• CCD are higher quality, have more pixels and are
generally more expensive• Size matters! The less light you have, the bigger the image
sensor you need to produce quality video
What to look for in a camera
• SD or HD• What kinds of inputs do you need?
– Fewer converters mean less latency• Latency• Video Sync (Genlock, Frame Sync)• Keying• What kinds of outputs do you need? (projectors,
streaming, recorders, etc.)
What to look for in a video switcher
• Projectors • Recorders• Live Streaming• Overflow displays • All of the above? Do I need routing capability?
What do I do with the video output?
• Poor Lighting – Lighting makes video• Latency – Every conversion, non-sync’d source adds
latency
