I have these .MOV files. They are were from the same camera from the same event and some will load and some will not and give me the same error. I did notice that the ones that would load also have a .sfk file created and the ones that don't do not ( I don't know that this .sfk file does). All video play fine with a video player, just some wont load at all into my project media at all.
I'm happy to provide more details, I just don't know what info is needed. I had problems with .MOV files and Studio 13 so I upgraded to 17 Platinum and changed a Deprecated Features to Enabled the QuickTime plugin. But now this is happening.
