THE CURSE OF THE PHANTOM AUDIO!
Something happened this time, however, that COMPLETELY stumped me! I tried to do this with a very brief clip--about two seconds. When the audio was supposedly extracted, I couldn't find the audio clip to delete it. I pasted it in anyway. Sure enough, double audio. I deleted the clip, thinking I'd get rid of both picture and sound.
I gave up on just going to "Restore Clip" in most cases, as sometimes I've done some difficult editing I want to keep. Instead, what I do when I drag a clip from the Clips Pane to the Clips viewer is copy and paste before I change ANYTHING, then drag the copy BACK into the Clips Pane, which should result in an EXACT copy of the original without having to reimport from the camera no matter what gets screwed up.
So I took a DIFFERENT COPY of the ENTIRE SEQUENCE and tried extracting the audio from the WHOLE THING. What happened was the usual "silent movie" effect--EXCEPT FOR THE TWO SECONDS I ORIGINALLY TRIED TO COPY! THE AUDIO WAS STILL THERE--SEEMINGLY UNREMOVABLE!
To test the possibility of some special curse on those particular two seconds, I imported just that part again from the camera and removed the audio by the usual method. This time it worked. I went to "Restore Clip" to remove any changes on the clip I was pasting into, then edited it back to where it was. BEFORE CHANGING ANYTHING, when I checked it, the phantom audio was STILL THERE! ALTHOUGH I HAD RESTORED THE CLIP--AND THE PICTURE, INCLUDING PARTS I HAD DELETED, CAME BACK!!!!!!!
WHY WAS THE SOUND I HAD ACCIDENTALLY PASTED IN THE ORIGINAL VERSION STILL THERE IN THE RESTORED VERSION??? WHY, WHY, WHY???????
Now I am going to delete everything and start all over with the copy in the clips pane. If these two seconds of "phantom audio" are STILL lurking in the Timeline, I GIVE UP! I don't know how this happened or how to fix it!
