Need alot more information. Type of file, programs you know how to use, What problem if any are you having. P.S. And please turn your cap locks off.
I downloaded a movie and it is very dark.As I am quite new to this I thought that there was a programme similar to adobe photoshop where you can enhance the picture quality.
Thats the problem with downloaded movies if its captured that way it is difficult to change it back. Some video edditing sofware can do this but with a 2 hour movie its very system demanding. Just like with Adobe Photoshop if you make a change in size, quatity or change the image and save it you can't change it back if you don't have the original work. At least without effecting the original quality. I will adjust my picture brightness with the moniter, video driver or TV to compensate.
