Frame problem – Pyro Movie FX Review

Hey I love this app and have been using it for about 3 years making movies but I noticed recently that when I add fire, smoke, or explosion the video, the video will play a frame multiple seconds ahead of the video then come back to where the video is supposed to, and it will do that throughout the video. It is only when I add an effect to the video that it messes up the frames but I don’t know why.
