 Video (Web – Medium Quality) MPEG4, H.264, 300 Kbps, 480x360/480x270, AAC, 32Kbps, 22khz, mono
Video (Web – High Quality) MPEG4, H.264, 1.6 Mbps, 640x480/640x360, AAC, 64Kbps, 32khz, mono
Video (Web – High Definition) MPEG4, H.264, 1.5-3 Mbps, 1920x1080/1280x720, AAC, 128Kbps, 44.1khz, mono/stereo
Many tools are available for encoding video (i.e., preparing it for upload):

Webcasts
A webcast is the distribution – live or on demand – of a single media file to many simultaneous listeners or viewers. Any format can be used for a webcast, but the most popular are Real Video, Windows Media and Flash.

Streaming Media
Streaming video or audio is an on-demand stream of content from a server to remote users, often using progressive download (the entire file need not be downloaded before viewing can begin).
MIT Services
AMPS provides fee-based streaming services for a variety of delivery options. In addition, AMPS provides resources for Rich Media Capture (a computer-generated form of streaming media which shows a presented, his or her presentation slides, and audio of the presentation in a single view).

Podcasts
Podcasting is a non-streaming presentation of audio or video content that people can download and access from a mobile device such as an iPod. Podcasts are often release episodically, and users subscribe using RSS feeds. Sites such as iTunes allows anyone to create and distribute a podcast.
For more information, see:

Direct Download (non-streaming video)
Videos may be hosted on a website (such as an Athena locker), but will rely on the browser to have the appropriate plugin(s) to play the video. Merely pointing to a video file using "http://" in front of the file path will make downloading the file easy, given sufficient bandwidth. Note that storage lockers have space limitations, and video files are generally very large.

Physical Media (e.g., DVDs, tape, blu-ray)
Videos maybe stored on DVDs, tape, blu-ray, hard drives, or other physical media. These can make a particularly effective strategy for Archiving.
