V9 DPX RENDER TIMES - Half speed of V8?

Using Resolve Lite to conform and consolidate Arri Alexa ProRes projects.
After conforming the original media (Arri PR), I deliver DPX files to our main Resolve suite.

Resolve V9 is giving me an average of 15-16 FPS when creating the DPX files from ProRes.
Resolve V8 was giving me close to 40 FPS. Same system, same hard drives and shared storage.

Any reason why I am seeing more than a %50 drop in performance?

Can you provide your system specs?

I want to do a test on this here.

What flavor and resolution of ProRes?

What timeline resolution?

Which V8 software version?

Do you have an HD5770 card as your GUI card, or just the single Quadro 4000 graphics card in your system?

- ProRes 444
- 23.98
- 8.2.2
- Yes. I have an HD5770 as the GUI card

Thanks Dwaine!

With a 5,1 MacPro with OS X 10.8.2 and CUDA 5.0.24, using a single GTX570 graphics card, and dual 2.4Ghz 6 core Xeon CPU's. ProRes444 HD file on an HD timeline, no corrections, to HD DPX RGB 10 bit files.

Render Speed

8.2.2 = 40 FPS
9.0.1 = 40 FPS

So no difference here. Are you sure you had the same OS X and CUDA versions with 8.2.2 that you have now with V9? Are you using 9.0.1? Your current CUDA version is pretty old. You should probably be using 5.0.17 at least. 5.0.24 should work as well. You might try that and see if that makes any difference.

But with no corrections and no sizing, the performance is basically down to the CPU performance, for the ProRes444 decoding, and file system I/O. I would not expect either of those to be affected by Resolve versions, and they don't seem to be on our system. GPU performance for a PR to DPX transcode should not have much impact.

Thanks Dwaine!!!
Really appreciate you testing that. Must be an issue on my end.
