DESTINATION RULE

Ask what opens it

The receiving app decides, not the file suffix

Confirm the specific program, device, or platform on the other end before picking an output format.

WEBM in practice

A video is a container plus codecs, and both determine what plays back - Picture, sound, captions, chapters, metadata. Getting the container right does not guarantee the codecs inside are supported.

KNOWN LIMIT

The failure mode worth testing

Encoding can be slower and older Apple or editing software may not support WebM reliably.

ACCEPTANCE TEST

Evidence to collect after conversion

Test browser playback, seeking, VP9/Opus support, dimensions, and audio sync.

Shared rules for this video family

  • Check every stream: Confirm audio, captions, duration, frame rate, and sync after conversion.
  • Confirm the audio track: Verify the destination container actually carries the expected audio codec.
  • Name the target device: Choose codecs that the final browser, phone, TV, or editor can decode.
