Reason to film in 4k
I'm coming to the end of filming a project for a drama course and I’ve shot everything in 4K on my Galaxy S20 Ultra. As I’ve been going along I’ve been editing shots and scenes, and have kept my composites and outputs at 4K.
However, I’m wondering if that’s the best approach and am questioning whether people film at 4K so they have greater resolution on output, ie, a native 4K, or whether it’s so they can reduce the resolution of the composites and outputs, eg, a 4K shot on a 1080 canvas, and make use of having more shot space to play with, eg, being able to zoom into a shot without losing quality, being able to add pan in post shooting, removing scene artefacts, etc?
I appreciate the answer is probably “It depends” but in terms of the latter approach above, is that a reasonable way of looking at it?
Thanks in advance,
