What to expect
- The H.264 video is re-encoded to VP8/VP9/AV1 with Vorbis or Opus audio, which is lossy.
- WebM plays natively in browsers but is not accepted by some older TVs, phones and editors.
- Re-encoding takes processing time but can produce a smaller file at comparable quality.
Frequently asked questions
Will I lose quality converting MTS to WebM?
Yes, some. WebM cannot hold H.264, so the video is re-encoded to VP8, VP9 or AV1, which is a lossy step. At a well-chosen bitrate the loss is usually small and often offset by WebM's more efficient codecs.
Why convert AVCHD MTS to WebM?
WebM is Google's open, royalty-free web video format that plays directly in modern browsers, making it a good choice for putting camcorder footage on a web page without a plugin or codec pack.
Where does a WebM file play?
Any modern browser opens WebM natively, and VLC plays it as well. Some older phones, TVs and editors do not accept it, in which case MP4 is the more compatible target.
Is the WebM smaller than the original MTS?
Usually yes at similar quality, because VP9 and AV1 compress more efficiently than the H.264 in the MTS, though the re-encoding step itself takes time.
