Please help I have tried all the fixes I can find on this site and YouTube. I shot a movie on my iPhone 12Max and it's a move file and I cannot get it to load to MM17Platinum. It states that file type os not supported. I've converted file to MP4 and AVC and neither work either. They are blank although I don't get the error message. I added an HEVC extension and can play the video on my PC but no joy with MM17. I converted the file using QWinFF and also unclicked the legacy AVC button in preferences. I've spent about 10 hours on this so far and cannot find a way that works.
I have 2TB SS drive and using GeoForce GTX960M with 20GB ram and 2.6Ghz i7 Intel
Please help me :(
