As you probably know, quicktime videos are saved as .mov files. However, if you rename the extension to .hdmov, the video will play smoother, have better color accuracy and brightness, and you won’t experience image tearing while watching it. There are several programs that play .hdmov files, but I recommend Media Player Classic. Also, Dave’s Trailer Page is a great place to directly download movie trailers to your hard drive. If you’re not familiar with renaming extensions, you have to go to Tools –> Folder Options in Windows Explorer, click on the View tab, and deselect “Hide extensions for known file types.” Now you can see that all your quicktime videos have a .mov extension afterwards. Just add an hd before it, play it in Media Player Classic, and you should definitely notice a difference like I did.
