I purchased and installed Movie Studio 2022 Platinum yesterday and I am getting glich and jitter of the video in the preview and exported movie which does not appear in the original video, how do I solve this as it makes the product unusable? Note, the video is AVI 1920x1080 @ 29.97 FPS... I don't get the problem with AVC 1920x1080 @ 50 FPS videos.
