Methods of Delivery

VHS
This is a very common form for delivering video that can be played in a consumer video cassette recorder that uses a 1/2-inch tape. If you are able to capture video into your computer from an analog source like a VHS tape, you should also be able to output the edited video back onto the tape. Generally, this is as simple as making sure the cables are set to OUT, and pressing RECORD -- no compression necessary. Check the documentation with your video editing software for specific instructions.
DVD
Digital video can be burned onto a DVD-ROM if you have the appropriate drive. DVDs look like CDs, but have a much larger storage capacity—more than enough for a feature-length film compressed with MPEG-2. DVDs require special hardware for playback.
CD-ROM
Digital video can also be burned directly onto a CD. While video must still be compressed in order to fit on the average 640 MB CD, it does not have to be compressed as much as a web-delivered video. The result is larger movie dimensions, faster frame rates, and much higher quality video.
Web
Video can also be delivered over the Web. There are three main methods for delivering video over the Web: standard download, progressive download, and streaming. See "Is Streaming Right for Me" for more information about each method. At this time, because of bandwidth considerations, web delivered video is generally the poorest quality because it must be compressed so much. To deliver video to a user over the Internet, the video must be copied to a web server and then linked from a web page. For more information, the UGA Streaming website has extensive information on uploading, embedding, and linking to streamed files.
