I'm trying to edit a film my friend and I put together, I've done it hundreds of times before. My camera is a Canon Vixia HF200, when I import my clips through iMovie every once in a while it'll tell me that some of the clips didn't go through due to error. But since today no clips are uploading, it only says error uploading so and so number of clips out of so and so number of clips were not uploaded. I need to upload through iMovie so that I can transfer my clips to Final Cut Pro, which is what I use to edit. Can anyone please help me out?

import them to your desktop or a folder and when iMovie
starts let it search for new movies.

I have them in a folder on my external, how do I let it search for new movies?

click on file then import and browse to the folder
