Supported file formats
Every format Timeliner accepts, and what a reviewer gets for it: a thumbnail, instant playback, playback after processing, or a download. This page is built from the same rules the app uses, so it stays current.
Every format on this page uploads. A format that is not listed is refused at upload; zip it first and it uploads as an archive.

Video that plays after processing
No browser can play these containers directly, so they play once Timeliner has made the streaming copies. Longer and larger clips take longer.
