Validity per codec
- VP8: pair common - VP8 inside WebM is the original WebM target.
- VP9: pair common - VP9 inside WebM is the standard VP9 upload pair.
- OPUS: pair common - Opus is the default audio track inside WebM.
- AV1: pair common - AV1 inside WebM is the second standard AV1 upload pair.
- H264: pair invalid - WebM is built for VP8/VP9/AV1; H.264 inside WebM is non-standard.
- H265: pair invalid - WebM HEVC is non-standard and most players reject it.
- PRORES: pair invalid - non-standard; effectively invalid for WebM distribution.
- MPEG4: pair invalid - non-standard.
- AAC: pair invalid - non-standard; WebM uses Opus or Vorbis.
- MP3: pair invalid - non-standard.
- FLAC: pair invalid - non-standard.
- PCM: pair invalid - non-standard.
