VP seems to have become unusable for me overnight, and I'm not sure why, but it's pretty upsetting. Here's what's going on.
I have a project with four video files in the media bin. Three of them are fine -- or were yesterday, when I was working with them -- but the fourth one is a nightmare. I can click on it so it's showing in "clip preview" but when I try to actually watch the video, only the audio will play, even when the file has been fully cached. The video will move when I drag the start or end points of my selection, but when I click on 'start' or 'end,' it goes back to the old selection with the video frozen. I can watch the clip ONLY if I'm trying to watch a part of it I have not selected to add to the sequence, but once I add it to the sequence, I can no longer watch it in clip preview or change its endpoints. Sequence preview works maybe half the time; the other half it gives me the audio only.
I've tried deleting the file and clearing the cache and adding it all over again. I've tried starting over with a new VP project. That worked fine until I added something to the sequence, and then everything went crazy again. The project is not very complicated so I don't know why VP is freaking out.
Any ideas of other things to try? I guess the file itself could be corrupt but it's the same type & provenance of the other files I'm working with, and it was working fine yesterday.
ETA: I started a new project with a new video file I've worked with before, and this is still happening. I add the clip to the bin and click on it so it appears in "clip preview." I select the part I want and add it to the sequence, no problem. When I try to do it again, I can ONLY watch video I do NOT have selected.
The first image will play; the second one will not. If I drag the endpoint in the first screenshot to encompass the cursor, the video freezes.
