Hi.

I read about the new BM RAW here:

Quote: 'This results in significantly reduced processing on your computer, making it faster to decode and use the files'

I wonder what Resolves new hardware requirement for BM RAW will be?

Specially for a Constant bitrate of 3:1 or a Constant quality of Q0 in both 4K/UHD and in HD?

You also write: 'it’s multi‑threaded and it works across multiple CPU cores.'
Please also tell us, what is the max number of cores. Do it scale well all the way up to 32?

Regards Carsten.

No problem with 24p UHD timeline (out of BM samples) on MacBook Pro with AMD Pro 455 and 4 cores at 2.7GHz. If anything it's GPU which is struggling.
If you have powerful CPU you can switch debayering to CPU and save your GPU for other tasks, like NR.

With the test clips, the additional load on a hexcore Windows machine, compared to prores, is negligible. Averages 30%-40%

The GPU, with some grading, ranges from 70% to 100%, but it's a a pretty weak 600 series gtx, with only 2GB vram. CDNG 4K would never playback real-time with full debayering, but this GPU manages to do it with this 4K test footage.

CPU decoding is now less an issue, which is how it should be.

For CPU any intel 4th gen and later will be ok with the instruction sets. For what I've tested so far with the clips provided as samples I can say that without an i7 or 3rd gen (or ealry) you'll have to lower the decode quality for a UHD+ source. But still on all my machine (even those that should not support Resolve) the new BRAW is lighter then everything I've tested so far (even lighter then Gopro Cineform). As GPU any of the last couple year would work. On the nvidia side any GTX 1050Ti or later, on amd side any Radeon RX 500 series or PRO will do any moderate work (and by moderate I mean low to non NR and low Fusion, if those are in need go bigger with a GTX 2070 or GTX2080 nonTi/Ti with i7 8th gen+ and 64GB ram at least).
