I am trying to slice up a 4GB video into smaller chunks. I've experimented with it before, and it worked just fine yesterday. But, i must've done something, and when i play the vide in the Sequence 01 monitore, the playback jitters the same few frames over and over again, and then moves on and does the same thing to the next frames. It does it kinda fast too. Sound plays just fine.
What did i do to mess it up?

Thanks!
