Processing notes
- Processing demand varies with the codecs found in the source while preparing FLAC from HEVC.
- High-resolution HEVC footage increases conversion time and memory use.
- Check picture, sound, and timing in FLAC before removing the source.
Compatibility notes
- FLAC is appropriate for music archives, mastering, and lossless playback.
- The HEVC source must contain a readable audio stream; a silent container cannot supply one.
- For the next step, account for larger files than lossy formats.
Troubleshooting
- No sound found? Play the HEVC source and confirm it contains an audio track.
- Extraction from HEVC slow? Reduce other processor activity and leave the page open until completion.
- Inspect the generated streams when an app recognizes FLAC but refuses playback.
