I'm working with simple stuff where I makes videos by combining screen and audio records. The screen record output file is mp4 , which I know is an inefficient editing format in HitFilm. It both does and should use all my 4,34 GHz 8-core CPU juice. However, very often it goes down to 25% use, leaving 70% unused, and of course lags like it's installed on an underpowered system. How can I keep HitFilm use all available CPU-juice when it indeed is needed by the application anyway?
