What changes when you convert WEBM to FLAC
- WEBM video is lossy and FLAC audio is lossless: converting cannot restore detail the source already discarded, and the FLAC audio file will usually be larger than the original.
- WEBM video transparency is flattened onto a solid background because FLAC audio has no alpha channel.
- WEBM video animation cannot be expressed in FLAC audio; the first frame is converted as a still image.
- The video’s audio track is extracted and re-encoded to FLAC audio; video frames are discarded.
