Playback lag with low opacity visuals
Greetings,
I am working on a youtube video, but I have encountered a problem. The top visual layer has its opacity lowered anywhere from 30% - 5%, depending on the clip (pictured below with the yellow fx). However these layers with low opacity cause extreme playback lag when playing that section of video. If I delete the clips or increase they opacity to 100%, the playback lag goes away. Initially, when I made the clips, they didnt cause any lag at all, but at some point the started causing playback lag. I am really confused and I have not been able to find any other mention of this problem online. Anybody know what this problem might be?
