H.264 - Chroma Subsampling Settings

It would be awesome to choose between different chroma subsampling settings in the H.264 codec. Often I can't solve bending issues in red colored gradients because the default setting is 4:2:0. Changing to 4:2:2 could help a lot and for really good quality outputs I would love to choose 4:4:4. Please make this possible for your render community 🙂

Hi, we do make a lot of digital out of home content and for these screens we have to use MP4/H.264. Filesize isn't much of a problem because these screens don't stream videos from a web source, they download it onto a small local drive and play from there. The 4:2:0 chroma subsampling for the H.264 codec sometimes causes very visible artifacts in redish colors and we currently need to fix these with noise but of course some clients don't want to have grainy ads.

Hello, 

We've not had many requests for H.264 output with different chrome subsampling options. Can you tell me a bit more about your workflow? I usually use customers with this requirement exporting in ProRes. 

Regards,

Fergus
