Stupid questions regarding CUDA, OpenCL and Premiere 6

[Tero Ahlfors] “but when it crashed it crashed HARD.”

can you give the work scenario where it went down? – material on timeline, HD, 2K etc?

[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.

I also tried to bring a 1 hour 20 minute online of a movie (HD prores, HD DPX sequences) that I did with CS 5.5 in. The computer hung up when I just imported the sequence from the project file. Opening the project itself seemed to work better and it ran better than in 5.5.

how limited do you find it as a straight cutter without the GPU hack? will that HD ProRes and C300 play together ok without it? (as in full res 1080p say?) the video demo for the hack indicates that dissolves are red bar without openCL – you get that too? not that… I wildly care there, I’m not much of a dissolves person to begin with. also I take it CC is a red bar without the GPU hack?

this is the thing really – if the hack is liable to turn psychotic, then an awful lot of us are left with a system that can’t do realtime dissolves even.
that is a teeeensey bit limited. I kind of expect to be able to three way colour correct without rendering – up to 1080p – these days. early doors mind you – the app is out three days like.

I forgot to ask – what’s your system?

HD prores/DNxHD footage works great in full quality realtime even with a couple of effects on it. There’s the red bar but you don’t have to render. The Mac is the same as you were thinking of buying except this one has 16 gigs of RAM, a SSD for the system drive and the Pegasus RAID.

Please go get 10.7.4 if you use OpenCL, it is much improved!

Cheers

These two blog posts by Todd Kopriva give you the run down on what CUDA and Open CL can handle in Premiere Pro CS6:

https://blogs.adobe.com/premiereprotraining/2012/05/opencl-and-premiere-pro-cs6.html

https://blogs.adobe.com/premiereprotraining/2011/02/cuda-mercury-playback-engine-and-adobe-premiere-pro.html

To summarise: CUDA accelerates ( and in some cases produces higher quality renders): scaling, deinterlacing, blending modes, color space conversions and some effects, namely:

Alpha Adjust, Basic 3D, Black & White, Brightness & Contrast,Color Balance (RGB),Color Pass, Color Replace, Crop, Drop Shadow,Extract, Fast Color Corrector, Feather Edges, Gamma Correction, Garbage Matte (4, 8, 16), Gaussian Blur, Horizontal Flip, Levels, Luma Corrector, Luma Curve, Noise, Proc Amp, RGB Curves, RGB Color Corrector, Sharpen, Three-way Color Corrector, Timecode, Tint, Track Matte, Ultra Keyer, Video Limiter, Vertical Flip, Cross Dissolve, Dip to Black, Dip to White, Push transition

Open CL accelerates all of the above apart from: Fast Blur effect, Gaussian Blur effect, Directional Blur effect, Basic 3D effect.

This fxguideTV episode is also worth a watch: https://www.fxguide.com/fxguidetv/fxguidetv-145-ae-and-adobe-cs6/

Be interesting to see whether the degree of acceleration provided by Open CL cards matches similarly specced CUDA cards.

[Tero Ahlfors] “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.”

A kernel panic?

This doesn’t sound right. These started after installing Pr?

This happened once after making the OPENCL text hack. I tested the new Premiere without the hack and I didn’t have any problems like this. I’ve never ever gotten a kernel panic on this Mac. I’m not a hardcore IT guy but what I figured out from the panic log was that Premiere was the culprit.
