I have been trying out HitFilm Express and am very impressed with it but it has major performance issues on my laptop.
Once I am into a project, even when I am doing basic functions like trying to scroll or zoom in and out in the timeline, the application jumps and freezes and CPU max's out over 95%. Also, when I do scroll, the images and audio disappear in the tracks until the scrolling stops and it redraws it after a few seconds.
This all makes the program pretty much unusable as it stands. I have a reasonably good laptop computer that I have been using for with other video editing products like ShotCut and VideoPad and it has performed relatively well without any freezing or very slow response times. I updated my video card drivers to the latest version.
Any suggestions or performance tweaks I can try?
