Issues with screen dimming during videos on S4.

I have a Galaxy S4, and only recently started having issues with the screen. When I watched videos before, the screen didn't dim. Now, the just during the past few days, it has started dimming during videos. I have always had my screen set to dim after 45 seconds of inactivity, but never had a problem with it during videos until now. Is there any way to change this?
