Hey Marc,<br>
<br>
you need to align the two in Premiere or Final Cut or any other cutting program that allows several audio tracks. I cannot give you specifics about other programs because I do that in Premiere. The principle of it is not too hard
to do though. You will have two audio tracks that you can align, which make
things easier. Align the two audio spikes you created with a clap. You
have to zoom in really close to do that. Then shift the new audio track
forward or backward a little until you hear no echo anymore, if you play
both audio tracks simultaneously. Delink the original audio from the video track, link
the new audio to the video track, delete the old audio track and you
are good to go. <br>
<br>
There are plenty video tutorials on You tube. If you cannot find a good
one contact me again and I have the link to one somewhere that I cannot readily find at the moment (for Prmiere only though, but the principles are explained which should enable you to transpose the process to a cheaper video cutter.)<br>
<br>
Best of luck,<br>

Hi All -<br>
<br>
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.<br>
<br>
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.<br>
<br>
Many thanks in advance for any help!<br>
<br>
