“Audio 2: 5.1 AAC (source: 1997 DVD)”
AAC isn’t blu ray compliant. Why not AC3 instead?
Is that still a concern? I figured most people play MKV as such.
The Premiere I used only exports 5.1 audio in AAC. To export 5.1 AC3, I would have to take the extra steps of exporting the audio channels into individual PCM tracks, then re-combining them back 5.1 AC3 in Audacity. I didn’t think that was necessary, and didn’t want to re-encode the audio more times than needed. I can make a separate AC3 track if needed, but I consider the Laserdisc stereo the primary sound mix. Listening back and forth, the fidelity of the laserdisc sound is superior.
