Convert WebM to FLAC

Settings appear after you choose a file.
A WebM video already holds compressed sound, so FLAC will not improve it. Choose it to store that sound in a lossless file. Lost detail stays lost.
WebM or FLAC?
Keep WebM when
- Size matters. A FLAC of a video's sound is several times larger than the sound in the WebM.
Pick FLAC when
- The sound goes through an editor and is saved many times without more loss.
- A player or a library only takes FLAC.
About WebM and FLAC
WebM
An open video format made for the web. Common for screen recordings and clips saved from sites, less so in media players.
FLAC
Lossless compressed audio — CD quality at roughly half the size of WAV. The archival format of choice for music collections.
Questions
Why is the FLAC so much bigger?
FLAC keeps every detail of the decoded sound, while a video's sound is stored in a smaller, lossy form. A lossless file made from a lossy one only gets bigger.
What happens to the video?
The FLAC holds only the sound. The WebM stays as it is.
Do the title and artist stay?
With the FFmpeg lines, yes: FFmpeg carries tags such as the title across to the FLAC.
Can I convert a whole folder at once?
Yes. Drop them all here. In Terminal, one line converts every WebM in the folder.
