This is very strange, although it doesn't seem to be affecting the actual exported video: When working on a video's timeline, I've been noticing that some of the clips are showing the image of an unrelated clip that I AM using in a completely separate video! Even the file in the bin is labeled as it should be, but is showing the "picture" of that unrelated clip! On one video I ended up deleting and re-inputting my affected clips, but on another video I just ignored it for kicks and grins, and the exported video came out fine. Anyone happen to know what causes this?
