Hey y'all . . .

I have a pretty high-powered computer that handles most video with no problem. However, when I import GoPro video, the system bogs down. The timeline and preview stops progressing when I'm playing a clip, for example. I can still hear the audio but nothing advances visually. I tried dropping the preview settings down and that didn't seem to help. This only seems to happen with GoPro footage?

Any ideas on what the problem / solution is?
