Gudday mate,
Ghosts in the machine is all I can say because now it seems to work just fine.. I’d already pre-keyed the footage in AE and it looked great. But when I put it on C4D the key worked great but the image was semi transparent. I always back my work up to another drive and when I opened the back up, the damned thing works perfect!! Still can’t get the main project to work without it being ‘ghosty’ but the back will work just as well. If anyone has a theory, I’d love to hear it!
