Is there a way to copy and paste repeated copies of very short portions of a clip? I'm editing a video of a lecture, and there's one point, that lasts about 20 seconds, where the video image and the audio are confusingly different (don't ask). I'd like to replace the confusing visual by copying and pasting in something from elsewhere in the project. Is that possible? And if it is, how would I do this WITHOUT changing the audio?
Thanks!
