Video Playback running choppy

[amac84]

Hi, i've been working on a video project for the past month and the video playback has been running excellent.

today i uploaded a new video project and the video is now running choppy. Its not the same movie but the quality of both films are the same (they both came from the same editing house) and actually the new project is only a 5min short.

When i re-open the first project, the video still runs as smooth as ever, but in the new one, its choppy. I have the same set up in both preferences.


any help would be greatly appreciated!

Is this second project a .mov (Quicktime) file? PT WILL open other video formats but they don't work fer squat.....
