reframing a 4K Red image
on Jan 11, 2011 at 4:07:19 am

Hello!

I recently directed a film shot on the Red. I wish to reframe a number of shots, but I'm not sure how far I can push in on an image before I'll start getting noticeable image degradation/blur when the film is projected at 4K. I've been told not to exceed 115%, but others have told me I can safely go much further. Is there a general rule on this?

Thanks,
Andrew

Are you really screening in 4K?
Most films in theaters are still shown in 2K! If it's really 4K, I wouldn't go much further than 115%, but 2K will give you much more.

Hi, Uli

In all likelihood, we'll be screening in 2K, but there's a possibility that we might screen in 4K. Is there a general rule for reframing for 2K exhibition? I'd love to punch in 130 - 140%, but it feels pretty risky.

Thanks!
Andrew

Try to remember that 4K is 4 times the information of 2K. That means you can fit about 4 2K frames in a 4K frame. Punching in to 150 is fine for a 2K delivery but it also depends on the quality of the image, the surrounding shots, etc. There are a lot of factors.

Why not run some tests to help solve the problem.

David

Peace
