I have video (avi) from a screen capture (1920x1080) recorded with CamStudio that is crystal clear and plays smoothly when I play it in Windows Media Player, but when I bring it into Adobe Premiere at the same resolution and render it, it becomes blurry and choppy. I even created a new sequence from the avi file so that the settings from the source would be used to create the new clip. Still no dice.

Next, I created a new sequence at 720x405, imported the avi file, scaled it down, and rendered it out at 1920x1080 and everything looks crisp, but it still plays choppy.

Any idea what the hell is going on?
