Stupid questions regarding CUDA, OpenCL and Premiere 6
-
[Andrew Richards] “CUDA is not what he is enabling. “
wellll, quite right yes – but the point would be that this baby can actually be made play with the hardware on all our minds?
your cuda drool post makes it pretty clear that what’s going on over in windows completely slays the OSX environment, but as a rejoinder – that involves windows.
I still view that as a howling gale of things I don’t want to get involved in.My primary concern would be that this can lock into recent OSX GPUs to get me rolling with an open format timeline, with geometrics and colour correction.
Everything past that, I am going to be nipping around the Adobe ecosystem like a gambolling Lamb for – from AE, PS Speedgrade etc.
The one thing I need to know is that the timeline is ready to function within say, V1 to V4 for stacked shot alternates, with shot dissolves, with certain shots having geometrics and CC, and all this up to 1080p with the kinds of avchd stuff coming off the kinds of cards being popped out of all the cameras out there, on an iMac made in the last 12 months with over a gig of vram (and sure, please drop fidelity as needs be)… well then.
given the inherent power of the new timeline, avid equivalent trimming, FCP style timeline malleability, scrubbable bins, effects architecture etc – as long as I simply know that steady playback is ready to go, at up to 1080p resolution on 12-ish month old hardware – then…
I tell you, I am liable to do an Orson.https://vimeo.com/user1590967/videos

I think you guys are making way too big of a deal with CUDA. All it does is accelerate scaling functions and some of the built-in effects, like Premiere’s color correction. If you don’t use any of these, you will see no difference between a CUDA and non-CUDA card. I’m running an ATI5870 (not a CUDA card) and with 1080p/23.98 ProRes footage, I’m getting great performance.
Premiere offers a performance throttle by changing the viewer playback resolution. So if I set it to 1/4 and apply an effect like MB Looks, it will still run in real-time without rendering. If I swapped this card for a Quadro 4000 (a CUDA card), I wouldn’t get any better performance with this same MB Looks effect.
If you bounce heavy effects out to After Effects instead of doing them in Premiere Pro, then it also doesn’t matter, since CUDA and the Mercury engine don’t benefit AE.

You’re right to an extent Oliver. If a plugin isn’t CUDA optimised (i.e. MB Looks), a CUDA card won’t help. But if it IS optimised for it, you can pile effect upon effect on your footage and get realtime playback at full resolution. I’m yet to test out how far you can push an OpenCL card on a MacBook or iMac, but I’d hazard a guess that it won’t be as far.
One other benefit of the Nvidia CUDA cards is that if you use After Effects, it will also take the load off the CPU when working with RayTrace 3D compositions. The difference between CPU vs GPU acceleration, like in Premiere, is night and day. As far as I’m aware, OpenCL based cards (i.e. ATI cards) aren’t supported.

[Andrew Richards] “Does anyone know if OpenCL Mercury Playback Engine GPU Acceleration is possible on Windows?”
The Windows version has that opencl_supported_cards.txt so…
-
[Aindreas Gallagher] “thunderbolt won’t be in a position to hande GPU throughput until later, faster 100 Gbps specs are introduced in about three years time. I’m repeating that like a parrot mind you. 20Gbps doesn’t and won’t cut it for external GPU throughput.”
You saw this, right? https://www.youtube.com/watch?v=koE5r0Kg1Rc&feature
On LongGOP codecs, CPU is important.
Effects on those LongGOP codecs, GPU is important.

There is no OpenCl code compiled on windows at this time. We focused on Mac first for OpenCL support. The card file being there on windows doesn’t mean it will work…

I tried the OPENCL text hack and it works, but then Premiere got pretty unstable in certain situations e.g. manipulating effects in realtime. The accelerated 3-way corrector worked pretty nice on 1080p prores.

Thanks Shane.
It was interesting to see the video was different from the text instructions.
Outside of trying to impress someone with your ability to use Terminal, I’m not sure why you would bother with this approach. Showing the Package Contents and then editing the file with Text Edit seems not only easier, but less chance of typing something wrong.
So what’s the catch? If this is all it takes, why doesn’t Adobe do it? Is it because Adobe didn’t test the various other ATI configurations?
