Were both your main video and your "B roll" footage shot with the same camcorder?
It could be that you are mixing video formats, and the footage you use for your second video track using different project settings.
This is less of an issue in version 11. But, in earlier versions of the program, mixing video formats can cause this kind of issue.
Yest both footages were shot with the same camcorder. So that shouldn't be the problem.
Could it be that I export it wrong? I export the video as a MPEG HD 720p 30.
Lately I've also been finding difficulties after exporting it as WMV. At some points the video will become slow and faltering as if it couldn't render or something. A few seconds later in the movie the images just run nice and smooth.
I'm sorry, then. I don't know what would cause this shakiness.
Although, when I watch your video, I can't see the shakiness -- so it must not be too bad!
