About this conversion

What happens

After consent, the server converts supported streams using the selected quality and resolution. A separate validator checks WebM structure and output streams.

Limits

250 MiB input. 15 minutes, up to 3840×2160, and 500 MiB output.

Things to know

VP9 video with optional Vorbis audio. Encoding takes time; this is not lossless remuxing. Unsupported codecs, HDR, extra tracks, malformed containers and excessive duration or dimensions are rejected.
