So many ways to color correct…

I work in docos and have enough grunt to run R3D files in 1/2 res. Takes a bit longer with the final file renders but the proxy files are nearly always HD ProRes/ DNxHD so I nearly always revert to the RAW

File size is rarely the issue. It’s the TIME that’s the big issue. Again, I’m not wrong that a large portion of mainstream TV series and feature films are not being done from Raw files. There are pros and cons either way.

BTW, whenever I’m asked, I always tell clients not to shoot at a rate greater than 5:1 — I think that’s about the sweet spot for R3D size and artifacts, particularly with smoke and very fine-detailed images (like grandstands or forests).

I agree but there is a certain doco mindset that says ” I have the budget for UHD and want to shoot 6k so 8:1 is OK”. Hard to argue. I’m very pleased with my sweet spot when I shoot which is 4.6 4:1 cDNG on the Ursa Mini. Gives me punch in room, looks good and so far no artifact issues.
