I'm Using my Canon Vixia HF R11 before I return it for something more compatible with my Macbook Pro, I finally was able to import my videos to iMovie by concerting it on Handbrake and then on Bigasoft Total video converter. I don't know what it was, maybe the software i used or maybe the number of times I converted the files, but the video quality of my movies were TERRIBLE. Please help, thanks
