I am a novice when it comes to handling video. I've never used anything more than iMovie. I have a lot of SD mp4's of home movies and I wanted to be able to watch them full screen in my three year old MBP without the video looking completely like garbage. I know it won't be HD quality, but I just want it to be bearable. What are my options? Is there any simple drag and drop applications that can do this? Can Quicktime pro do it? Any answers will be greatly appreciated.
