Thanks for the reply.
The footage does play fine in-camera. I transfer the files by using my card reader on my computer. Then, I import the footage into premiere pro cs4. I have a pretty crappy computer (Dell Vostro 230), but my exported footage is fine if there is no movement. I’m thinking it might be the FPS I’m using, but I’m not sure.
Here’s the video:
