I've been editing a pretty big project with multiple clips, and after I produced the project, I noticed something that has been infuriating. In only one instance of my video, there is a random black frame that flashes for just a millesecond in between two of the clips. I have done everything I can to try and fix this, including deleting and replacing the clips on the timeline. I have also zoomed in fully to ensure that both clips are placed directly next to each other. I have also checked the clips themselves and there is no black frames in them which could cause this problem; it only seems to show up after I render or produce the video as well. This is incredibly frustrating and any help anyone could give would be much appreciated. Thanks.
