About Truehd to Flac

[foreverbelmont]

I have a .m2ts file with a Truehd track, and i want to use eac3to to convert it to Flac. All i have to do is simply use the command like

eac3to xxxx.thd xxxx.flac

and then waiting? THX!

Hi! Welcome to doom9!

You're almost there, but not quite. Start with the following:


eac3to input.m2ts


THis will first print out the listing of each PID in the m2ts file. It will look something like this:


M2TS, 1 video track, 1 audio track, 1 subtitle track, 2:19:03, 0.106p
1: Chapters, 12 chapters
2: h264/AVC, 1080p24 /1.001 (16:9)
3: DTS Master Audio, French, 5.1 channels, 24 bits, 48kHz
(core: DTS, 5.1 channels, 24 bits, 1509kbps, 48kHz)


In my example I have DTS-MA, but for your sake, let's pretend track 3 in this case is TrueHD.

You then re-run eac3to like this


eac3to input.m2ts 3:audio.flac


This open the m2ts, selects track 3 (your TrueHD track), and re-encodes it to FLAC. You're in luck because eac3to can fully handle TrueHD on its own. DTS-MA requires having the Arcsoft decoders installed to get full resolution (else you fall back to the vanilla DTS "core").

Cheers,
