Bandwidth Considerations  Must take into account the bandwidth of the viewer  Significant buffering can occur if video requires too much bandwidth  Example:  Video compression – 512 kbps  Audio compression – 100 kpbs  Total Video bandwidth – 612 kbps  Would stream okay over DSL / cable / etc.  Many times your video editing software will provide total video bandwidth requirements.

Displaying Video Non-streaming  Example:  Does not use a streaming server  Waits until enough of video has buffered before playing  Uses H.264 encoding  Viewable on many devices including iPhone/iPad/etc  Not recommended or supported by the College. Takes up limited space on web server.
