Replacing audio in video
Could anyone suggest the best software to use for replacing the audio track in a video.
I would like to avoid having to re-encode the video if possible.
Normally I use Vdub for this process however the video I have is a MOV file using the Animation codec. The audio track in the video is uncompressed I have a WAV file of equal length ready to replace it.* Vdub wont load the MOV file.
* Mediacoder doesn’t appear to have an option to replace audio
* I don’t think AE or premiere can do this without re-encoding the video track (I hope I’m wrong)Any ideas welcome and Happy New Year to all!

I may be wrong, but I think that if you have an animation mov and you just replace the audio in AE and render out agai to Animation at 100% you will not re-compress the video but just replace the audio… Todd?!?

Technically, this would involve decompressing then recompressing the video, but since animation at 100% is mathematically lossless, there’s no generational loss.
This is very fast to do with Quicktime Player Pro.
Open the new audio track in Quicktime Player Pro.
- Edit > Select All
- Edit > Copy
Open the animation movie in Quicktime Player Pro.
- Window > Show properties.
- Select the audio track, then click the delete button
- Edit > Add to movie
- File > Save As… to a new file (to force Quicktime to flatten the movie).

Thanks guys for your ideas.
I don’t have QT pro but I do have access to Adobe audition and after a few attempts managed to get a decent result from it.The original video was using the animation codec at 75% quality so rendering via AE again at animation 100% would have maintained quality for sure but also increased file size (already standing at 5.6GB)
I’m amazed that AE/premiere/Adobe Media Encoder do not have an obvious facility to strip and replace audio tracks in video.

I may be way off here (wouldn’t be the first time) but I have replaced audio in Pinnacle and Avid NLE’s for a long time simply by muting the original audio track, add an additional audio track, import the desired audio and place it on that track – then adjust to taste. Although I haven’t had a need to try it in Premiere, especially with a QT .mov it should be possible there as well.
QT Pro (for $35 US) is the cat’s meow for a huge amount of conversion and edit functions. Worth every bit of the cost many times over.
