When I first got a version of Hitfilm (I can't, now, remember if it was Express or my recently acquired Pro2017) - I would be confronted with a dialogue box offering a chance to alter or approve imported media (fitting [or not] my project perimeters). For some reason, this doesn't happen anymore. Consequently, my videos are comprised of clips with different perimeters. This hasn't seemed to matter, when exporting, until yesterday.
I pulled off my first Mocha plainer track with a 90% result (a complicated move), but could not export it because it was too large. I'm thinking that, if that clip size was the same size as my project size, it would have gone through.
How can I fix this?
