About IVF
IVF is the simplest container for VP8, VP9 and AV1: a 32 byte header, then each frame with its size and time. vpxenc, aomenc and FFmpeg write it, and codec developers and test suites trade it.
An IVF holds only video, a stream of compressed frames with no sound.
Filepeek plays VP8 and VP9 in every browser, through FFmpeg where the browser lacks them, and AV1 where your browser decodes it. Export saves an MP4 that plays on anything.

Questions
Why is there no sound?
IVF holds only video frames.
Why won't my AV1 IVF play?
AV1 needs a browser that decodes it, as Chrome, Edge and Firefox do, and Safari on newer Apple devices.
Can I convert it to MP4?
Yes. Choose Export, then Save as MP4.
