I have gotten MKVs to build using CLI programs, now I am trying to do MP4 video, using the same AAC audio and merge/mux them together.
What CLI program do you suggest to mux MP4 and AAC please?

OK, but what if I have six separate audio files (as in PCM-L.wav, PCM-R.wav, PCM-C.wav, PCM-LFE.wav...)? I'm working with one 1080p ProRes MOV, and six 32-bit float WAV files for full 5.1 sound. I'm trying to merge them into one 480p (or 480i, I don't really care at this point) file which I would like to use for generating a good quality DVD screener. I'm assuming that I have to map the tracks correctly onto the file if they are going to place correctly on the disc, or no?
I'm on Ubuntu 13.04, running 64-bit on a Intel® Core™ i7-2600 CPU @ 3.40GHz × 8. I thank you in advance for any help you can give.
P.S. - When I try using MKVMerge, it rejects the video file, saying "the input file does not contain any tracks." Well, of course it doesn't... am I missing something?

What does your question have to do with this old thread?
Have you ever authored a DVD before?
The OP was talking about muxing together a completed video track with a completed audio track into MP4 format.
You're talking about taking high-quality source files and turning them into a standard DVD-Video disc. They couldn't be further apart. For the audio you will need to map the tracks in an audio editor and export AC3. For the video you will need to downscale and possibly interlace (what frame rate of 1080p?) then encode to MPEG-2 at a standard frame size, bitrate, and level.
Couldn't be further apart? OK.
I thank you very sincerely for the reply, smarmy though it seems to be. I think you've pointed me in the right direction.
