Let the hive mind of Engadget get that for you.
"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!"
"With that said, movies are filmed in what could be considered 4000p. IMAX is even higher. But unless media is available, I dont see the point beyond outputting from a beefy computer with SLI videocards to a projector."
Digital media (downloaded content) could probably be made available in the future, when/if these screens become available at an affordable price. Whether studios would want to release 4000p content into the wild is highly debatable, even if they are able to hamper it with what they perceive to be unpenetrable encryption and DRM. I could see home videos shot in 4000p, though, at some point in the future. Wouldn't it be funny if your home movies looked better than the video the studios and networks allowed you to see?
