Converting to FLAC won't restore lost quality
Your M2TS file has already undergone lossy compression. Converting to FLAC preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your M2TS file may contain Blu-ray metadata metadata. FLAC has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

FLAC is lossless audio compression — bit-for-bit identical to the original at roughly 50-70% of WAV size. Converting between these two formats lets you improve file compatibility across devices.
Full Name: M2TS uses Blu-ray Transport Stream, while FLAC uses Free Lossless Audio Codec. Compression: M2TS uses Lossy, while FLAC uses Lossless. Color Depth: M2TS uses 8-bit, while FLAC uses —.
Your M2TS file is decoded and re-encoded as FLAC. Converting M2TS to FLAC maintains high quality with CocoConvert's optimised encoder settings.

What Happens When You Convert M2TS to FLAC
The audio track is extracted from your M2TS video file and saved as FLAC. The video frames are discarded.
Your M2TS file is opened and the container is parsed to identify audio and video streams
The audio stream is extracted — if it's already in the target codec, it's copied directly (no quality loss)
If transcoding is needed, the audio is decoded and re-encoded as FLAC
Video frames, subtitles, and chapter markers are discarded
The FLAC file is saved with preserved metadata (title, artist, etc.) where possible
