I'm asking in relation to the vse as a standalone, as well as the 3d viewport.

Where can I specify what chroma subsampling I want for my output? i.e. 4:4:4 vs 4:2:2 vs 4:2:0?

Are presets applied to each of the render options that aren't otherwise visible? What are these options?

I feel like I'm missing something. Is chroma subsampling a "physical" film only thing? I know you can select the sampling for your 3d renders, but I mean that's variable whereas chroma subsampling is like 3 main options. I'm guessing those are different things.

Do 3d renders not follow the convention of chroma subsampling. And when just using the video sequence editor then, do I not get the option of specifying a chroma subsampling?
