I tried putting an aiff file into my timeline and it made the audio on my narration track lower and now my video ads a few frames every second or so to make up for some sort of time accomodation that this aiff file created for my project. I don't know where to even start to fix this problem. Help!
just a thought to try to narrow down what's causing the issues, try converting the aiff to wav and see if that changes any of the issues your having. Also check the kHz. I've encounter some stange issues here and there mixing 44.1 kHz and 48 kHz in early versions of Premiere.
The aiff file may be "associating " to a QT Player in the background.
Try changing that but definitely try converting to a wav.
