Under the Video preferences? I’ve shut that off, no change… The file isn’t particularly large either – less than 1Gb – and I’ve worked with larger clips from the same source. I found a temporary workaround by just passing the clip through Movie Maker, though I’m afraid that I might have lost clarity in the process.
Also, I noticed that while running through the clip and watching my task manager, the CPU usage is around 10% for the half that works. When it hits the sticking point, the usage jumps up to around 80%. Not sure if that helps diagnose the problem.
Thanks for helping me work through this!
