videos imported to imovie are solid green
Hi,
I took some videos with my Samsung Galaxy S3 phone and uploaded them to my Mac. I want to use iMovie to splice the 5 short clips together into one video. For some reason when I import the videos using iMovie, the videos don't appear for editing as I've seen in tutorial videos on YouTube. All I see is green where I should be seeing video stills. I can click play and hear the audio but am unable to see video. Is there any way to fix this? Thanks
