I just purchased the $59 AVI Video Editor and tried it for the first time last night. I captured several clips from my sd card A of my Canon HF S200. When I finished editing, I removed the card and produced a movie which I uploaded to You Tube. My movie is black. I did try to save the new project but apparently didn't. Also, the audio on my timeline was very "jerky". How do I properly capture video? I have watched all the AVI tutorial videos which are very abbreviated.
