timeline staggers and stalls on playback
Hello Everyone. During playback my timeline staggers and stalls. My clips exclusively contain 1280 x 720 60 frames (mostly all of these clips I conformed them in Cinema Tools to 23.97 for a slow motion effect. Also, I have 1920 x 1080 shot at 29.97. When I'm watching my project on my cinema viewer (all frames mode) at a certain clip the beach ball begins spinning. It also, does this during playback on the editor's Canvas. I've always been a little confused as to what settings I should choose for my playback options. I guess now would be a good time to clear that up if that could be causing the problem. Thank you all for your input.
