I'm fairly new to Blender and video editing as a whole. I understand that the playback in Blender's VSE needs to load a video once before playing at full framerate. After playing through a video once, when I return to the beginning, I'm able to play it smoothly at 60fps. However, after around 1000 frames, I get a brief freeze in the video followed by ~24fps playback for the remainder. The audio plays fine at full speed, not freezing with the video and finishing long before it. I've tried this with multiple different clips (flv files recorded with OBS) and the problem is consistent in each clip, though there doesn't seem to be anything wrong with the clips themselves if just played raw through a media player. Does anyone have a fix for this?
