So me and my friend decided to do a call of duty nightmare campaign playthrough, we would upload it on each of our youtube channels, for me there is a problem tho, that is that hitfilm somehow manages to desync the audio, slow the audio down or speed the video up, how can I prevent this from happening, also there is always a section at the end of the videos that don't have any material, I dunno if it is because the game can move between fps quickly and hitfilm wants to have a constant fps rate or because of my recorders (Bandicam and Fraps (both of them have this problem)) the problem doesn't occur on any other games, please help me out. Thx
