Hey. Installed the Hitfilm 4 express today, and it seems great.. BUT..
I was going to try it out and noticed that the clips i was adding, became veery slow in both the ''trimmer screen'' and the one on the other side. First i was going to trim my video using the trimmer option. To do that i thought i was going to view the video until the part i wanted to start on. But, it was impossible. The sound comes first, and the footage comes lagging, jumping 2-3 seconds between every image that poppes up. (I'm a really bad explainer, but if you dont understand, just ask me and i'll try to describe it more exact). The footage is a MP4 file. Is this lag because hitfilm do not support it? Do i have to convert it to any other, like mp3, avi or wmv?
