I recently bought an Aiptek Action HD GVS camera and have some footage on it. I watched it on my non-hd tv and it looked great, but when I put it on my MBP, the quality drops greatly. Dark shots get grainy and outdoor shots look pixelated. Why would this be? Is there a better way to get files off of a SD card then plug in the camera? Or are there settings or programs that allow for better HD playback?
