4K Grading & Monitoring

[Joakim Ziegler]

Actually, I’m kind of the other way around, capturing in as much resolution as you can makes sense, and sending it to VFX in 4k makes sense too (those extra pixels help in tracking, matching, and all sorts of stuff), but seeing color is not resolution-bound.

For me personally, we also do film out and DCP only in 2k at the moment, but that might change soon (well, it may change for DCP, film out is dying).

The few times I’ve had to deliver 4K was because the client insisted “it’s so freakin’ cool to have a 4K master!”

FYI – We’ve yet to see anyone saturate a PCIe Gen2 x16 Xpander box Kevin. I’m sure the day will come sooner or later, but not just yet.

My guess, and BMD would be the ones to make the definitive call on this subject, is that the number of NVIDIA CUDA cores and VRAM capacity would have more of an impact on 4K performance than the PCIe Gen2 x16 bus bandwidth (which = 80Gbps theoretically, a little bit less when figuring in system overhead and other related factors).
