Comment 13 for bug 770316

Hi,

I am seeing this issue on a Quad core as well, the interesting thing is if I import a single clip into Openshot and play it back it works, however opening an existing project with many joined short clips from the same source files results in the playback issues, it is so pronounced than on many of the short clips only a single frame is displayed in the preview window.

For what it's worth the files are 1920x1080 .mov files with AVC Video and PCM Audio from a Canon Digital Camera. I'm uploading one for the sake of testing here (May not be finished uploading until a while after I post this):
