EDIT: Okay, I just realised that it keeps starting from the very first frame. For example, if I’m on the timeline, and I want to mask something that’s a keyframe 5 minutes into the movie, when I open the Event Pan and Crop window, it acts as if I right-clicked on the first frame of the clip versus what I really wanted, so I have to keep scrolling on the keyframe timeline in the preview window to get to the part that I want. It’s incredibly frustrating but at least we’re somewhat of a step closer.
I’m not sure it’s the file, because it’s doing it with everything I upload. I’ve even tried converting the file and nothing. Not sure what to do. I need this issue fixed by tomorrow, since I have to edit a project for class due Monday, and haven’t been able to work with it. Mediainfo and the other program you gave me both say the videos codecs are installed on Vegas and ready to use. Not sure why I’m still having this issue though.
