R4D 8K vs 4K

Deciding between 8k and 4k resolution for an upcoming job.

Also a bit torn about going ProRes Raw vs 422HQ.

My plan was to do 4K ProRes Raw but would love to hear others thoughts. I am bummed that it’s not true 4k it is actually 3.8k 16:9. My A and B cams are shooting true 4k.

I’ve only used the 6K head so these recording options are new for me on the 8K head.

Would love to hear what combo of resolution and codec y’all have been liking the most.

I should note this is for a proper documentary production so it’s not straight to web. Hard drive space is still a consideration though.
