Once your video has been created, produced, captured, and edited for viewing, it may need to be encoded for Symposium submission. So that files are not too large and can be more quickly streamed or downloaded by viewers, they must be compressed and formatted. Doing such is called “encoding” and requires encoding software.
The device that compresses data is called a codec. One or more codecs are built into various programs for preparing video. Please encode your video in either mp4 or m4v format before submitting to Symposium.
