Thanks in advance!
It's an mpeg transport stream in a .ts wrapper. Layout would be as follows:
Video (MPEG2, 80Mbps, CBR, All I Frame,422@HL)
Audio1 (Track1/PID1) 1 pair LPCM(SMPTE 302M)48kHz
Audio2 (Track2/PID2) 1 pair LPCM(SMPTE 302M)48kHz
Audio3 (Track3/PID3) 1 pair LPCM(SMPTE 302M)48kHz
Audio4 (Track4/PID4) 1 pair LPCM(SMPTE 302M)48kHz
FFmpeg is out because it won't encode LPCM into .ts.
I'd rather not go down the AVISynth wormhole because I'm Mac based but if there is a CLEAR solution (as opposed to random AVISynth fiddling) by trying that route, I'd definitely be willing to give it a go.
I tried AME/Adobe.
I tried Telestream.
I tried Resolve.
I haven't tried Compressor this go around but I know it's there to try if I don't hear anything else.
I've done this a bunch with hardware encoders but I'm on my own now and a dedicated HW encoder is not in the budget for this project.
I look forward to and appreciate your input!
