OpenCL acceleration on Macbook Pro with Certified card is BAD

[Martin Smith]

Just saw there was another thread with the issue. Sorry i posted too fast.

I guess that answers my question. Basically it’s not working. Maybe that’s why we never got any specs on speed improvements with OpenCL.

Nothing to see here either.

So far CS6 on Macbook Pro = FAIL

So much hoopla for a nothing release. Even Speedgrade is a one-way harddrive bloating experience. UltraKey render errors, crashing etc…

If you watch Activity Monitor you will definitely see Open CL slowdown. With Open CL the CPU is between 200-480% usage. MPE only is 500-600+% and renders mucho faster for me. Let’s hope there is an update within a few hours that explains everything.

Sounds like you might want to consider Avid or FCP X since you are having such a miserable experience.

Yeah, I’ve been thinking about it but neither of them give me the performance that Adobe Premier gives me. Neither of those two you want me to use gives me the real-time playback for native formats that Premiere has. i think it would be a step backwards. Have you done any testing with your Boris Red Key compared to CS6 Ultra Key?

To tell you the truth, when I have the need for chroma keying I usually use Primatte in After Effects. I havent had the need to do just chroma keying in Premiere.

Although whenever I use the accelerated effects like the 3 way color correct, most of the time I get real time playback with my Quadro 4000 CUDA card.

I just seem to have a positive experience with CS6.

You don’t have to use Send to SpeedGrade (which transcodes to DPX), you could export an EDL and link to existing media. That method adds no extra space to your hard drive.

If you’ve got problems troubleshooting OpenCL performance with the MacBook Pro, let’s do that.

• What kind of footage are you working with?
• Does footage play any differently with the Mecury Playback Engine GPU Acceleration (CUDA) disabled?
• Are the latest drivers for your AMD card installed?
• Have an external RAID? How is it formatted? How is it connected?
• Are you running OS X Lion, or Snow Leopard?
• Any other devices connected?

Working with MTS files from Nex7.
Playback is much better with Open CL disabled.
Apple does not allow driver updates until they say so, the machine is up to date.
External RAID is Raid 0, attached through Sonnet Tempo Pro eSata card.
OSX Lion 10.7.3
Apogee Duet2 connected for sound, external USB hub connected for mouse and external Apple keyboard.

Erik,

I will say that “today” the OpenCL playback is not as good as software in all cases. I am working on getting an official post out. I can only say that today is only today… New technology sometimes takes a few weeks to iron out…

Cheers

Dave

I know you can’t really go into details but is there a possibility that we will be able to do 1/4 editing of 4K R3D on Macbook Pros?

[Kevin Monahan]

Very subjective, but my MBP is a Corei7, 8GB RAM, NVIDIA GeForce 330M. With 4K footage, I need to drop resolution to 1/8 for zero dropped frames on playback and for editing.

At 1/4, I drop frames too much, so that it wouldn’t be suitable for editing. YMMV with your system and the AMD card. I suggest giving the trial a spin with your footage and your computer.
