Good to know
- Three video formats: MP4 and MOV (from phones and cameras) with AAC or MP3 audio, and WebM with Opus or Vorbis audio. Other containers such as MKV or AVI are not accepted yet.
- The original codec is not kept: The sound is decoded and written again as MP3 or WAV. WAV avoids a second compression, but it cannot improve the original audio.
- Long videos are fine: Because the video pictures are never decoded, an hour-long video takes about as long as an hour of audio.
Frequently asked questions
What if the video has several audio tracks?
The main (first) audio track is used. Separate commentary or language tracks are not extracted in this version.
Are the video title and other tags kept?
Tags such as title, artist, album and cover art are not copied into the new file. The result contains the sound and the technical information a player needs.
