What happens to your file
The video stream is dropped (-vn) and only the audio is kept, re-encoded to MP3 with libmp3lame at VBR quality 2 (~190 kbps). What you get back is an audio file the length of the original clip — no picture, no thumbnail.
Settings this conversion runs with
| Engine | ffmpeg |
|---|---|
| Video stream | Discarded (-vn) |
| Audio codec | libmp3lame |
| Audio setting | VBR quality 2 (~190 kbps) |
What changes
- We check the WEBM file for an audio stream with ffprobe first — a silent screen recording or a camera clip with no microphone track will fail fast rather than hand you an empty file.
- The audio inside a WEBM file is already compressed, so this is a second lossy pass. It is fine for listening; it is not the route to take if you plan to master or re-edit the audio.
