Hi, I have been using Vegas for over a decade, since it was owned by Sony, and have just upgraded to Vegas Pro 20.
I was using Vegas 16, and on 16 there was never any problem using mov files filmed on my iphone. Now all of a sudden however, glitched squares have started appearing when I import any video from my iphone into Vegas. The files themselves play perfectly well outside of vegas, but as soon as they are imported into vegas the glitches appear. They appear on the preview, they appear with no track FX added, and they appear on the final rendered video. Nothing I do seems to fix this issue. I need to be able to render these videos for my job!
Any help appreciated.
