[Aindreas Gallagher] “can you give the work scenario where it went down? – material on timeline, HD, 2K etc?”
Most problems came about when I cleared my whole project panel, imported footage (HD prores, C300 test footage) and made a new sequence. There wasn’t any video in the source or program monitors and the playback controls didn’t work or Premiere would hang up. Also changing MPE settings (I did this for testing purposes) while having a project open is a big no-no. While you can now manipulate effects in realtime some of them will freeze your system so hard you will need to hard reset the computer. This can be done accidentally because Premiere will keep playing pretty much no matter what you do. I got the Mac OS panic when I sent some C300 footage from Premiere to Speedgrade. I was testing Speedgrade and didn’t even use Premiere.
For some strange reason the 4K and 5K R3D files worked without any problems. I couldn’t get any performance boosts for the red footage with OPENCL. It worked in 1/4 quality just as it worked without the GPU acceleration.

[Jeremy Garchow] “Is that totes for realsies, or just for realsies?”
Like totes really realsies! Also I got one of those Mac OS X “hold the power button down to shut down the system” in five languages kernel panics and the error log had something about Premiere and Atiwhateverdriver in it.

[David Cherniack] “The hack means means they haven’t tested the card. The card may fully work or it may cause instability in some cases, though I really haven’t heard of any except when loading 5k still sequences with effects on a 1gB of memory card.”
Yeah. It worked for fine for some footage and situations but when it crashed it crashed HARD. I’m still going to test it out and maybe figure out the limits of it, but when I’m doing something for realsies I’ll probably disable it.

[Aindreas Gallagher] “hey – unstable as in crashy?”
Unstable as in not updating the video in source or program monitor, not accepting any command inputs and freezing up the Mac (MenuMeter just showed the computer ate all the RAM and processor power) so you can only move the cursor on the screen so you have to hard reset.

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.

[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…

[Oliver Peters] “.. SG is missing curves, user-drawn shape masks, tracking and an effects node tree (like Color)”
SG has shape tracking and it’s layer based so I don’t think it’s missing nodes.

[Aindreas Gallagher] “Premiere doesn’t have CUDA its dead in the water in those scenarios dealing with native camera codecs. that’s right isn’t it?”
As said before R3D footage works pretty nicely, Prores too. I can try out some 5D mk II footage tomorrow, but I can’t say anything about c300 and af100 footage. Unless you have some to share or know where I could find some.

We have an i7 iMac with a Pegasus RAID as a extra edit unit with CS5.5 Production Premium and now I downloaded and tried the CS6 trial on it. Even without the GPU support it is very responsive and wayyyyyy faster than CS5.5. I can run R3D 4K in 1/4 quality with a couple color correctors on it in realtime. 1080p prores and DPX sequences also work without any hassle in full res.

[Lin Sebastian Kayser] “Lin Sebastian Kayser – Adobe SpeedGrade Engineering Director – Founder of IRIDAS”
Hey,
I was wondering on how I should be working with transitions (cross dissolves) when sending the timeline as DPX footage from Premiere. When we use Lustre we just render out the necessary heads and tails on the dissolvable clip and put them in place manually. Speedgrade renders the dissolve as it’s own clip but it doesn’t help because you can’t “dissolve” the grade. Or can you? The EDLs work great when using the original footage clips.
