I have downloaded a few hd videos in .ts format. They are 1280 x 720 59.94 fps and dolby 5.0. I am looking for a way to convert these videos to apple tv. Or convert them so i can bring them to imovie. I have tried roxio toast. But it changes the frame rate and video size. When i customize the output, the quality looks terrible. Is there a way to convert these files but keep the quality and frame rate?
