I'm a newbie with Avid. I'm taking some online courses where they allow you to download project files to follow along with the instructor. I just completed a splicing of back and forth shots with extreme long shots and medium shots.
The instructor then taught me how to do an overwrite in the middle of the timeline. I noticed after completing that, there was a duplicate clip somewhere else in my timeline. I highlighted one clip, clicked delete and moved the video timeline over.
Now, the video no longer plays in the record monitor (it's grey), but the audio plays just fine.
