By playing around with the clips, I found out that the first clip plays normally as long as it does not touch the clips next to it end-to-end on the track/timeline. But then the following clips, even if I move them apart, are all black on the preview screen. If I press "play" while the next clip is selected, then all the following clips play normally. But I if I start "play" from the beginning of the video, it either gets frozen on that first particular clip that originally had the issue, or the screen is all black on the following clips. I don't know what is causing that to happen, but that appears to be the problem.

I'm in the process of making a video. When I play it in the preview box, every time it gets to this one particular cip, it freezes on the image (first second) of the clip. The audio still plays, the clip won't play, and then the next clips won't play, either. When I select that particular clip itself and hit play, it does play. But after I export it as a video, when I play the video, again it freezes on the image/first frame of that clip, and remains there for the rest of the video, while the audio continues to play normally. I cannot figure out how to fix this so that it plays normally. I'm using Windows 10, 64-bit. Does anyone have any suggestions/advice? Thank you.
