maximum resolution

Movie Cameras of totay are usualy very high def, and even 1080p masters are down converted form the actual film it's self. However there is a lot of old movies that were either filmed at lower resolutions simply because the technology was not there, or they could have been fillmed at a high resolution (for theater) yet mastered at DVD resolution for home video. Some film studios either destroy the film original or lockit up some where and forget about it. Digital remasters of old movies come from the original film source which is why they look so much better. However some movies just don't have that, so upsampling is the only thing availible.
