What’s happened to Mercury Playback Cuda setting
Hi all
After the latest update of Premier 7.2.0 I only have the option to choose between “Mercury Playback GPU Acceleration (Open CL)” and “Mercury Playback Software Only”.
I have a 17″ MacBook Pro early 2011 model with a Nvidia card in it and up until now the GPU Cuda acceleration has been working great.
I am working on a project that is using Arri Alexa footage shot ProRes 422 in log mode, i have been applying a lut on an adjustment layer to view it. Before the upgraded i could play it back in real time at full quality off my Thunderbolt drive, after the upgrade i could only get it to playback without dropping frames at 1/4 res.
If i switch to Software Only mode it will playback at full quality again but i am not sure if it is using the GPU.
I would think there should be 3 options in the “Video Rendering and Playback” settings i only have the 2 i have mentioned. Anyone else seeing this behavior.
Cheers

Hi Gavin,
Have you updated to the latest CUDA driver? you can find the link below:

Can you tell me what GPU is in your system?

Hi Peter
Cuda driver is up to date it was the first thing I checked. GPU in the Macbook is “AMD Radeon HD 6750M 1024MB”.
I am curious as to why i no longer even have an option to select Mercury Playback with Cuda?
Thanks for your time

Hi Gavin,
What your seeing is correct. AMD cards only support OpenCL. CUDA is proprietary to NVIDIA. That is why you do not see it listed as a renderer option.
Hope that helps.
Happy Holidays!

Hi Peter
If that is the case why is performance significantly worse when i select “GPU Acceleration OpenCL” as opposed to “Software Only” option.
For example this Alexa ProRes footage stutters badly when OpenCL is selected but plays perfectly in software only mode.
Also i have a yellow line above the footage in OpenCL mode and a red line in software only mode which is what i would expect visually to have, but performance is opposite to what i would expect.
Thanks

Hi Peter
I just remembered i have PP CS6 on this system so i loaded up some of this Alexa ProRes footage in a project threw on an adjustment layer and applied an effect that turned the timeline red, with OpenCL selected CS6 plays back the timeline at full res with no dropped frames.
So why does version 7.2.1 choke on the exact same scenario, further more i know this was working in the 7.1 version of Premier because i was playing back this stuff before the update last weekend with on dropped frames.
Thanks

I just rolled Premier back to version 7.0 and the footage is playing back no problems. It appears something has been broken in the latest update that affects Mercury playback with my configuration.
My exact specs are:
Mac Book Pro 2011
2.2 Ghz Intel Core i7
8 GB ram
Graphics AMD Radeon HD 6750M 1024 MB
Software OS X 10.9.1Cheers

Hi Gavin,
Thanks for the information. We’re currently investigating this problem. It seems to be effected slight older AMD cards.
Apologies for the hassle. I’ll write back with any developments.

Thanks Gavin. You have perfectly described the same experience with my MacBook 2.5 GHz Intel Core i7 17 – 16 GB RAM – AMD Radeon HD 6770M 1024 MB
I hope that Adobe will help us to resolve the issue early.
