I shoot video from a Versacopter using an SJ4000 Action Cam (go pro knock off). The video looks great in raw form -- HD quality. However, after I edit it using iMovie and then post it to Facebook or Youtube it is quite pixelated. Even the post-production file that I save to a local drive is pixelated when not viewing over the internet. Do you have any tips or is it just that iMovie sucks? I can't spend money on software at this point. Cheers!
