Converting MP4 to FLAC: what to know
MP4 is converted to FLAC when the sound of a video is needed for editing, mixing or archiving without any further loss.
Only the audio track is kept and the video is dropped. FLAC stores the sound losslessly, but it can't bring back what the MP4's compression already removed: the result sounds exactly like the video's audio track, only in a lossless container. You can save just a fragment by setting the start and end on the timeline.
MP4 or FLAC: which to choose?
MP4 (MPEG-4 Part 14)
MP4 is the most compatible video format: it plays on phones, TVs, browsers and social networks.
Best for publishing and sending videos - maximum compatibility at a reasonable size.
FLAC (Free Lossless Audio Codec)
FLAC compresses audio without any loss: CD quality at roughly half the size of WAV.
Best for music archives and listening in maximum quality.
What happens when converting MP4 to FLAC
Only the soundtrack is saved, the video track is dropped. You can trim the fragment and change the bitrate, channels and sample rate.
MP4 files up to 2 GB are supported; the actual limit also depends on the free memory of your device.
