4k file type recommendations
I have to request some 4k from a movie studio. They have asked what format I want. I’m wondering if anyone has had experience with this in CS4 and could recommend the best to work with. PNG sequence, QT uncompressed, Animation? This is not RED Footage and I’ve never used 4k before. Not sure what AE can handle.

First you need to know if you are working in 32 bit? 16 bit? Log or Linear color space?
Most likely dpx sequences.

Keep in mind you will need to add an adjustment layer on top of your footage with the cineon converter effect added to see the color space properly.

AE could handle any of these formats, and supports comps up to 30,000 x 30,000 pixels in size. I agree with Mr. Fuller that Cineon/DPX is probably your best bet.
I’d add one other comment — 4K frames are big! If you work in 32bpc, a single 4K frame will require just under 200 MB of RAM.
You didn’t mention how much RAM you have, but unless you need some 32-bit only plugins for the project, this might be a good time to consider maxing out your RAM and upgrading to CS5.

I’d check with the people you return your project too what they prefer you work in. I’d opt for DPX, TIFF or OpenEXR. I’d also as the above poster mentions highly recommend you going to AE CS5 – it’s a ton better at handling massive comp’s compared to CS4. 4K will mean RAM is an issue even in CS5 so I’d max that out. Just working in 2K stresses my setup out (16GB RAM / CS5).
Last but not least – do a trial round trip before you start working so you don’t run into format issues (i.e. gamma or color shifts). You want to sort that out before you’ve done X days or weeks of work.
Good luck!
