Make video render multithreading actually good #1

Currently despite using more CPU resources multithreading still finishes rendering in roughly the same time. This was the case even if I disabled autoresetevents that force threads to wait to retain frame order. Maybe has something to do with threads flipping back and forth between it and ffmpeg? If I put extensive maths calculations into frame calculations that caused the render time to increase significantly, then multithreading became noticeably faster than singlethreading.
