Supported Video on Demand Media Formats
Archives can provide a Video on Demand service for five types of media files (WMV, MPEG-2, MPEG-4, Flash Video (FLV), and MP3).
When uploading a file into the archive, a bitrate setting (high, medium, or low) must be chosen. The following tables indicate what
setting users should choose for different file types.
Flash Video (FLV)
Flash video on the Vision
2
server uses only standard definition and below video sizes. Flash videos must be encoded using the On2
VP6 video codec. The following table lists the recommended bitrates for flash video:
Windows Media Video (WMV)
Windows Media video can be encoded using WM9 and VC1. The following table lists the recommended bitrates for Windows Media
video:
The recommended bitrate for high-definition VC1 is 8-12 Mbits.
MPEG-2
MPEG-2 must be encapsulated in an MPEG-2 transport stream. The supported audio formats are:
MPEG Layer I
MPEG Layer II
MPEG Layer 3 (MP3)
AC3
The following table lists the recommended bitrates for MPEG-2 video:
High-definition is supported for playback to a set-top box. The recommended bitrate is 8-12 Mbits.
MPEG-4 AVC (H.264)
MPEG-4 files must be encapsulated in an MPEG-4 stream (.mp4). Files must have the MOOV Atom at the start of the file for fast
start. The audio must be in AAC format. The following table lists the recommended bitrates for MPEG-4 video.
NOTE:
The bitrates specified above are for playback on a PC unless otherwise stated.
MP3
A bitrate setting is not required when uploading MP3 files as the bandwidth requirements are modest compared to video. All MP3
files are uploaded using high bitrate.
NOTE:
Tablet users can only view and play MPEG 4 and MP3 files.
Set-top box users can only view and play MPEG 2 and MP3 files.
