M2TS to FLAC: the audio-stream extraction route explained
Converter.now selects the audio stream in M2TS, leaves the picture stream out, and encodes that sound as FLAC. The result is audio, not a silent copy of the video. M2TS demultiplexing removes Blu-ray-style packet prefixes, reconstructs program timing, and inventories video, language tracks, subtitles, and other transport-stream programs. FLAC output losslessly codes decoded samples and supports rich comments, yet it cannot reconstruct fidelity already removed by a lossy source codec.
Decoded media - A Blu-ray and AVCHD-oriented MPEG-2 transport stream using 192-byte packet framing. Encoded delivery profile - Losslessly compressed audio that preserves decoded samples and supports rich tags.

What the M2TS source carries and the FLAC output demands
What can fail when M2TS video container is interpreted
Extra audio, subtitle, chapter, and timing streams can be omitted by a single-stream conversion.
What Free Lossless Audio Codec cannot safely promise
FLAC does not make a lossy source lossless again, and some basic players reject less common sample rates or channel layouts.
How the FLAC writer handles this route
The verified FLAC profile uses lossless compression level 8; it preserves decoded samples rather than source codec data.
Checking the FLAC result before you trust it
Record the M2TS evidence before conversion
Inspect packet and stream structure, video codec, frame rate, interlacing, audio languages, subtitles, duration, and sync.
Test the FLAC file in its receiving workflow
Compare duration, sample rate, channels, peak levels, and tags with the decoded source.
The delivery decision for this M2TS to FLAC route
Take this route when only dialogue, music, or a soundtrack needs to reach a FLAC-accepting system; hold onto M2TS whenever its pictures, captions, or visual timing still matter.
What changes between the M2TS model and the FLAC deliverable
- The source stores a Blu-ray and AVCHD-oriented MPEG-2 transport stream using 192-byte packet framing; the destination stores losslessly compressed audio that preserves decoded samples and supports rich tags. Compare application metadata after that structural change.
- Metadata handling differs between M2TS and FLAC; do not assume every application-specific field carries across untouched.
