"I need help! I want a small pocket camcorder but I'm not sure which one to get. I don't want to fall into the hype of the Flip because I worry two hours won't be enough. What should I be looking for when considering a small camcorder and where can I get a good quality one with expandable memory? Thanks!"
The Red One is not used by the major studios. Also, Hancock was the only 4K film released in the last year. To date I think there have only been 3 or 4 4K releases and only 3 currently planned for future release. Not surprisingly all of the 4K films are from Sony, the only company manufacturing these projectors for public exhibition.
