4K or UltraHD upload

I have sold both resolutions about evenly. The pro houses know how to crop, squeeze, stretch according to their needs. Consumers? Old versions of Vegas? If someone has issues along those lines, Pond5 usually helps in most cases.

Interesting debate on aspect ratios here

I like shooting in 4k because you can crop down to UHD and only lose a very slight amount on both sides. I guess you could upscale a small % and go the other direction, but then you would lose some % on top and bottom of image.

I think we should all cover all the bases and just shoot 16K, you can do this with duct tape and 4 gopro's it's totally future proof and understandably the highest standard we should get to in the foreseeable future. I know what your thinking, and thank you for feeling like I am a genius...

Pond5, can we have a "like" button here?
