Hi Guys! New around here so please bear with me. I have downloaded Hitfilm Express for a Christmas House Mapping project and so far it seems awesome! I just seem to be having some trouble getting the Set Matte effect to function properly. I thought I had finally figured it out and it was working on one clip so I attempted another in the same way and that did not work and when I went back to the one that was working it then wasn't. So it seems to be something strange going on. I am using a Dell Inspiron 15 7000 Series 7559 which should have more than enough power to handle running Hitfilm without issue.
