I'd like to replace the audio track in movies captured w/ Snapz Pro X.

Movies typically use the Animation codec and all attempts up to now resulted in seriously degraded video
(video contains interaction w/ editors and other command line tools and it is essential that text shows
very clear).
I've tried iMovie and Garage Band, but I couldn't get those tools to operate on the audio track only, without re-encoding the video. Anything that can be done with those tools?

Alternatively, any good (and reasonably cheap) tool that I can use? I'm on Mac OS X on Intel-based systems.

Best regards,

Maurizio

Hello-
I'm confused, you say the video is degraded due to the animation codec, but you want to edit/replace the audio track?

You can use QuickTime Pro to extract the audio or video track, and then edit a replacement back in.

I'm sorry for the confusion, I meant that with all the tools I tried for editing audio, I was not able to preserve the initial quality of the video. What I was getting was:

w/ both Garage Band and iMovie:
Input: good video, crappy audio (my fault, not the tool) [this input was produced w/Snapz Pro X]
Output: crappy video, good audio.

Since my post I've been able to get much better video quality out of Garage Band, and although I haven't tried it yet, I've found similar settings for iMovie.

Still if there was a good way for replacing the audio track in a movie, I'd be interested in earing.

With QuickTime Pro you can delete an audio track, and then paste a new one in.

Hello-
You can use QT Pro to extract either track.

Open the .mov file in QuickTime Pro. Go to the Window menu to Show Movie Properties.

Then select the track you want removed, and click on the Delete button.

Open the sound recording you want to use (I'm not sure which audio file formats will be acceptable, for my tests today I just used a QuickTime, .mov file with no video track), select all, copy, then go back to the movie you want to add the soundtrack to and paste it in.
