I fixed the problem on the S3 for those who are wondering how to make it less dark for the videos. It's hard to see the videos when its playing a dark scene and all of the details is hard to see and just black. I downloaded an app called Twilight. Here you can change the color temperature. I have it at maximum. The intensity I have it at 15% and the screen dim I have it at the brightest. Make sure you put it to always. You will notice a big difference.
