As Jim points out, the Copy/Paste operation can go off with Audio. This has been around since at least PrPro 2.0.
There seem to be many scenarios, where this can happen, and it seems to be somewhat Project-specific, in that a user can do Copy/Paste in some Projects, and never see an issue, where on the same machines, with very similar Assets and setting it can manifest itself.
Usually, the Match Frame operation can "fix" the problem, should it surface. That would be where I would explore first.
Good luck, from someone, who has been bitten by Copy/Paste with Audio,
Thank you Bill and Jim. Jim, very helpful discussion. I read all comments.
So, if I want to do it right...What's the politically correct way to do the following:
1. I have an MP4, audio and video. I only need audio, to incorporate into another project and replace existing audio there.
2. What I had done, is I imported my MP4 into a new, blank Pre. project, chopped off what I don't need, unlinked video and audio, and saved only audio. Then I Copied/Pasted that audio into my big, working project, where I'm replacing audio.
3. Should I export my "audio only" file instead, and then import that audio only file into my big project, instead of Copy/Paste, and then work with it?
4. If that's the case, what should I export as? My final project is a video intended for YouTube. I am exporting as .mov
I am trying to export as audio only...Help!
It's asking me for file format, audio codec, sample rate and channels...Please advise.
Given the potential for having the Copied/Pasted Audio to unlink from its CFA (Conformed Audio) file, I would go the Export Audio route, to get a discrete Audio-only file. PCM/WAV @ 48KHz 16-bit would be my choice. Then, in your working Project, just Import that WAV file, and let PrPro Conform it (should happen almost instantly, though that will depend on your system and the Duration of that Audio-only file), and drag that to the Sequence Timeline.
Just bring in the original file. You can always use just the audio.
Thank you both. Very helpful.
