Where we are…
Harvard understands how to use, manage and preserve its documents, historical artifacts, books, objects of art, and physical course materials. These standards for ease of access, security, pedagogy, sharing, search and archiving are not being met for video content
Where we need to be…

Present State: Not Meeting Harvard’s Expectations for its Intellectual Assets
Present State: Not Meeting User Expectations

Where we are…
Where we need to be…
The Harvard community’s expectations for accessing video – a user experience defined by platforms such as YouTube, iTunes, LiveStream, Hulu, Skype, Netflix – are not being met.
DRAFT
This problem cannot be solved with local solutions – only a shared infrastructure will efficiently and effectively address current shortfalls
Digital Video Services
The Critical Need for Shared Infrastructure
As a result, the Harvard community CAN’T:
Internally publish a video to a secure environment
Externally publish a set of research or academic videos to a wide audience
Share video across schools, within schools, and with HPAC or other potential users
Efficiently search, store, catalogue, or track video, even within schools and departments
Rapidly innovate in the use of video technologies
10
SIGNIFICANT problems and challenges are emerging:
Current video support processes are primitive, manual, and labor-intensive
Schools are developing local solutions that are duplicative, inadequate and siloed
Service quality and reliability varies tremendously across Schools and Units
No effective strategy exists for addressing explosive growth in content and service needs

A PipelineFor Creation of Video Content
Content & Storage Management
Tools for embeddingvideo in teaching,
learning & research
A common service offering:• to the schools, the technical capacity to capture and process video material• for the University, a unifying process for collecting, describing and indexing video material from all sources
Providing the means to know what we have, who may see it, and where it came from
