[RNLD] Import .wav into .mp4?

[Mark W. Post]

Hi All -

I've been trying to figure out something which I feel *should* be pretty 
straightforward for quite some time now, but can't seem to find an ideal 
solution. Advance apologies if this is old hat.

I'd like to import a .wav file into an .mp4 container, ideally without 
using a big expensive program like Final Cut or Premiere. So, according 
to my poor understanding of things, an .mp4 contains an MPEG-4 video 
stream and a PCM audio stream. What I would like to be able to do is 
disassociate the audio stream, import a distinct .wav file, sync up the 
two streams audio-visually (i.e., with a clap), and export a new .mp4 
file. And, to make it even more interesting, I would like to know how to 
do this on both a Mac and a PC. So, the situation I have in mind is when 
someone has a good HD camcorder with terrible audio, but a good separate 
audio recorder, and needed one resulting file (e.g. to import into 
ELAN). I realize that ELAN also has the ability to sync multiple 
streams, but I'd like to know how to create a stand-alone container file.

Many thanks in advance for any help!

Cheers
Mark
