Hi Alan
What you're asking for sounds reasonable, and like you, the only way I know of to do that is to use
copy keyframe attributes.
It's true that using that feature
does copy many aspects from the original clip to the others - even other settings that have changed but that aren't actually keyframed - but I haven't seen any "random" changes copied over.
In other words, if the audio profile is changed on the copied-to clips, that strongly implies that you've previously made those same changes to the original clip.
If you start with a fresh clip and make the desired changes (again, I realize) and then copy the keyframe attributes, you shouldn't see any other changes on the clip(s) you copy them too. If you DO see an audio profile change when you've just re-created your desired effect on a clean clip, please post the details here and open a ticket with Cyberlink Tech Support.
