[Eric Santiago] “Then, of course, there is the “what if I need the 4K and up version of this movie” problem”
I always prefer to have the R3D files. These days editors punch in on shots as many DPs are encouraged to frame wider. Stabilising shots also punches in so I prefer to have the files that let me do this, not an HD baked version. Also fixing exposure or color temp issues, I much prefer RAW.
And these days I mostly work to a UHD finish timeline and make the lower res deliverables from that. Basic future proofing. It doesn’t cost much more to do it properly but redoing later does. False economy. Just wait till they tell you they want to sell to Netflix.
