IMovie Upload Error Message

Hi, drchen365,

The message means that there is corruption at frame 275, most likely a black frame. The solution is to scroll through the project in that area and look for any signs of corruption such as black frames. white flashes, or artifacts. Cut out any that you find and share out again. Best to first duplicate the project and work with the duplicate.

Here's an online frame converter to assist in finding the 275th frame.

So, for example, if your project is a 30 frame per second project, the 275th frame would be at the 9:05 mark (9 seconds.05 frames. (Edited).
