Premiere Pro :: Gamma Shift On Blackmagic SDI Output / When Using MPE OpenCL Or CUDA Acceleration
Dec 22, 2013
I'm experiencing an interesting issue in Premiere Pro CC. When using Mercury Playback Engine with either CUDA or OpenCL acceleration, the SDI output from my Blackmagic Design Decklink Extreme 3D+ card exhibits a noticable gamma shift towards the dark. When I switch to Software Only playback, the image appears as it should. The image in the viewer window inside Premiere is not affected in any way, just the SDI output. I've confirmed this behavior at multiple frame rates, resolutions and codecs, including ProRes, XDCam and RED. The "Linear Processing" checkbox in sequence settings makes no difference.
It makes the MPE acceleration unusable, and Premiere is very slow without MPE.

on my system Premiere Pro CC is only using GPU rendering with AVI output formats.
All other formats like MPEG2, Quicktime, H.264 are unfortunatly fully CPU rendered (=slow).
I just upgraded from trial to payed mode and when Premiere started the CUDA was already enabled (might have activated it during trial already).
But anyway I checked if my card was in the support txt file and also used the cuda.zip auto tool to make sure I had no typo.I did this for Premiere Pro CC and also copied the list into the Adobe Media Encoder directory.
So I started playing with input and output formats. It turned out that CUDA is currently only working with AVI output. I installed GPU-Z to check my GPU usage vs CPU usage in the task manager.
As soon as I pick any other output format than AVI - CPU usage during rendering is up to 80-90 and GPU at 0%.
With AVI output GPU ist around 30 and CPU in the 40ties or less as it should be.One of my old applications Cyberlink Power Produces 11 is doing the h264 rendering in half the time.
My System is running on:
Asus P8Z77-V Deluxe with 16GB Ram
Nvidia GeForce GTX 660 Ti (with current Driver - 332.21 )
Windows 8.1 Pro 64-Bit (with Media Center) and latest updates
Current entry in CUDA*.txt file (as printed by Adobe GPUSniffer):
GeForce GTX 660 Ti
And already tried:
GeForce GTX 660Ti
GeForce GTX 660

I am working with MTS files (AVCHD, 1920x1080, interlaced, 25 fps) in Premiere CS 6, Windows, and want to render my project with the same properties as h.264.

A common misconception is that CUDA/OpenCL processing is only used for rendering for previews. That is not true. CUDA/OpenCL processing can be used for rendering for final output, too.
But where/what are the options/settings to use CUDA not only for preview purposes, but for accelerating the rendering of the final output, too?

I have VideoStudio Pro X5 Ultimate (full paid for version) but I am unable to select the 'Enable Hardware Encoder Acceleration' option under Preferences/Performance as the option is greyed out.
I have an nVidia GTX660 Ti 3GB made by EVGA. This has a CUDA based CPU and according to Corel's advertising, VS Pro X5 is designed for this chipset, and so I cannot understand why the option to enable it is not available.
Some comments from Corel support I found that this option isn't required for CUDA cards as they are enabled and used by default. However, I have just done a test render of a 1920x1080 AVI clip to MP4 using H.264 and monitored both my CPU (dual Xeon E5420) and GPU utilisation. The CPUs hit 90% whilst the GPUs sat there doing nothing at all other than basic screen rendering rather than any encoding. Corel's comments are incorrect.
Also, I have a support case open with Corel but TBH, I don't hold out much hope as their last response was "If the hardware acceleration options are greyed out, then your graphics card software is managing the hardware acceleration. Please check with Nvidia whether there is an option to disable this. If there is, then once it is disabled, the hardware accelerations option will become active again.". Now, I don't pretend to be an expert in these matters, but I was under the impression that the hardware was enabled and managed by the drivers, and those drivers also offered out the functions of the card to other software that required it (API?), such as VS Pro when it needs access to the hardware acceleration to encode video. Graphics rendering on games works fine without me having to disable any graphics card software so why doesn't VS Pro?
For info, my hardware / OS is as follows:
Dual Xeon E5420 CPUs at 2.5Ghz (8 cores in total)
16GB RAM
EVGA nVidia GTX 660 Ti 3GB (with 310.61 beta drivers but still same issue with 306.97 release drivers)
240 GB Kingston SSD
Windows 7 64bit Ultimate with SP1
How to get hardware acceleration enabled using a GTX 600 series card? Or any other card that initially had the option greyed out?
I know that some people say that CPU rendering gives better quality, but I have a few hundred hours of old VHS and Video 8 tapes to transfer to digital and burn to DVD so as the quality isn't great to start with, I'm not too concerned about a few artifacts if I can significantly reduce the rendering time.
If I can't resolve this issue then I am going to claim a refund under Corel's 30 day money back guarantee as the product doesn't perform as advertised. However, I'd prefer to get it working as I quite like it.

I recently moved to CC in order to be able to work with Blackmagic's DNG raw files inside Premiere Pro. The move was successfull, I could work with such files. However, all of a sudden, I cannot import them into Premiere Pro. First, I cannot select the files and import them as a sequence, because the box will not activate.
Second, when I click on the folder containing the files, Premiere tries to import them, but then an error message appears saying "file format not supported".
I have seen other discussion threads about failures to import Blackmagic Cinema POCKET raw files, but I am working with files from the 2.5K Blackmagic Cinema Camera, which should give no trouble. In fact, as I said, I was perfectly able to work with them.
I have introduced no changes in my computer or the CC Suite, so this sudden error is all the more puzzling. The wav file will get imported, but none of the DNG files will.

I installed the 4 beta and am liking it quite a bit, but I'm having trouble with gamma shifts when exporting images. When I export the image, my blacks get completely crunched -- it doesn't match Lightroom at all. It's not just the JPEG being displayed wrong -- I've looked at the exported image on a few different computers and they always appear crunched.
My monitor is calibrated (using an X-rite i1 Display 2), and I re-calibrated it yesterday to make sure that isn't the issue -- it made no difference. I made an image to demonstrate the problem:

I'm running the latest version of Cuda, Premeire Pro CS6 has been updated but my renderer options in Project settings has been greyed out and I'm stuck using "Mercury Playback Engine Software Only".
One of the plugins I use in Premiere (FilmConvert) is using OpenCL fine, but Premiere doesan't seem to reconise it.

My setup is a Mac Pro with GTX 680 card for mac.I bought this card, thinking it would do what Adobe advertised: "GPU Rendering - Work faster and take full advantage of your hardware with full GPU acceleration, now included in Adobe Media Encoder."
I want to transcode FullHD H264 to XDCAM HD. GPU acceleration isn't happening. The GPU is idle, while the CPU does all the work. Sure, it I want do de-interlace or downscale to an SD Format, the GPU works. But apparently not for transcoding.
Adobe should not suggest that AME can take full advantage of my hardware, because it can't.

I was just making a short, 1:12-long video encoded as H.264 in an MP4 wrapper. I had edited the video in Premiere Pro CC, and was exporting through Adobe Media Encoder at a framerate of 29.97 FPS and a resolution of 1920x1080. I wanted to do a test to see how much GPU acceleration benefits me. So, I ran two different tests, one with and one without. The one with GPU acceleration finished in 2:09. The one without it took 2:40, definately enough to justify using GPU acceleration (my GPU is an NVidia GTX 660 Ti which I have overclocked). I am sure my benefits would be even greater in most videos I make, since this one had relatively few effects. However, I checked the file sizes out of curiosity, and found that the one made with GPU acceleration was 175 MB in size, and the other was 176 MB. While the difference is pretty small, I am wondering why it exists at all. I checked the bitrates, and the one made with GPU acceleration is 19,824 KB/s, whereas the other is 19,966 KB/s. I used the exact same presets for both. I even re-encoded the videos again just to test it and verify the results, and the second test confirms what the first showed. So, what I am wondering is: What is it that made this possible, and could this be used to my advantage in future productions?
In case it is in any way relevant, these are my computer's specifications:
-Hardware-
Case- MSI Interceptor Series Barricade
Mainboard- MSI Z77A-G45
Power Supply Unit- Corsair HX-750

Does Premiere CS6 offer an option similar to After Effect CS6's "Match Legacy After Effects QuickTime Gamma Adjustments" option?
Working with 5K .r3d files in my Premiere timeline and all exports from Premiere using the Animation codec and opened in QuickTime Player X appear too bright.

I am on a mac using CS5.5
I am making a short 10 second sequence to be displayed as a new years promo on two digital billboards. The requirements are that it is in .wmv format which doesnt pose much of an issue but is still relevent, and I need a copy in 880x256 and one in 448x160.
I have tried so many different avenues to get this to work over the course of a few hours and cannot seem to find a way for this to work out in my favor.
I started two seperate sequences each of custom settings with the specified resolution (880x256 and 448x160). I create the sequence for each and fit the frames accordingly.

I'm editing with RAW RED files straight from camera. Looking good but just want to know what my best possible output file and quality scheme should be.
I want to send out REDlog Film Gamma space for my color session and I've selected that for all my clips but is there any quality debayering setting I should select before output? And to what file extension output? DPX max bit depth? Uncompressed 10-bit?

I have a GTX 590 and a Geforce 7600GT graphic card installed in my system. Now, in the Iray Render Dialog it says that "No supported cuda devices detected".
I know that the GTX 590 IS a cuda device and is also a multi-gpu so that it should find 2 cuda devices on my system.
Cuda is installed and I use the latest drivers from nvidia "296.10".

Building a machine for my daughter to run Adobe Photoshop CS6 Extended.I have those 3 cards available. Will CS6 use AMD OpenCL? I get conflicting data.I have Win7-64 and Win8 in boxes as well. I assume Win7 is safer?
Last is multi core CPU's important or not?I have machines from 6 to 32 cores (singles from 6 to 16 cores, duals from 8 to 32 cores).Is core count or clockspeed more useful? The slowest chips are 2.5ghz, the fastest are 3.33ghz.

I've been using AE CS6 on Mac OS 10.7.4 upon release and updated to 11.0.1 when it was released as well, so for a while, but just today I started to get this warning-
"Ray-tracing on the GPU requires CUDA version 4.0 or later. Ray-tracing will use the CPU until you install the latest supported CUDA driver."
I am running a supported Quadro 4000 with the latest CUDA driver, 4.2.7, and about the only thing I know of that I have installed recently was the update for SpeedGrade today. Why I'm now getting the warning?

I have tracked this problem with different versions of everything but can't seem to zero in on a cause. This problem seems to randomly occur when I start up After Effects with other apps already running. I haven't isolated every scenario because sometimes it works, other times it doesn't, and still other times I don't need ray-tracing anyway.
If I then go about clicking things off and re booting, etc, it will eventually work. This past time I started AE after I already had Photoshop and Premiere Pro running. Safari, Outlook, Power Point, a couple of Finder windows and VLC player were also running. After I closed everything and then started AE first, it recognized my CUDA drivers and card.
Then I re opened everything I had open before ... loaded them full of content, went about the business of editing, ray-tracing, rendering, etc. with no issues.
I guess I should be happy with a solution that depends on the order in which I open applications and I am certainly glad there seems to be a work around (albeit a workflow stopper). Are there settings in my other apps that are blocking AE's ability to recognize CUDA? A conflict with VLC player?
With a relatively new iMac, gobs of RAM (some say is way more than needed), a fancy subscription to Adobe Creative Cloud with timely updates, I'd like to get into that comfort zone where everything just works.

Just want to know if this normal. The Opencl option can be checked in the 64 bit version of Photoshop but not the 32 bit. Just updated the drivers for the Intel HD 4000 graphics from the Intel website and Opencl is still not an option. HD 4000 supports OpenGL 4.0 and Opencl 1.1
So is it something I can fix or should I contact Intel about it?Here is the basic OS/video info:
Adobe Photoshop Version: 13.0.1 (13.0.1 20120808.r.519 2012/08/08:21:00:00) x32

Then I open the Performance tab in Preferences, and see that I cannot enable OpenCL and the GPU Acceleration like this:
How come? Is the problem of Mountain Lion or Photoshop? How can I solve the problem?

I see that there have been a number of posts about the Graphics Processor option to use OpenCL being grayed out. Here is another one:
PS CS6 & NVidia GeForce GTX 660 Ti with the latest drivers,
siffer_GPU reports: “OpenCL ok version 1.1 CUDA 4.2.1” but OpenCL remains greyed out.
I have no doubt that the problem exists at the Adobe end.

I have CS6 Extended, and while I can use some 3d features, the options are not available. I've removed and reloaded PS, the graphics driver has been updated, removed completely and then reloaded, but nothing works even though I have never actually gotten a warning that the card isn't supported. It is supposed to be compatible with OpenCL but this isn't available for some reason.
The graphics card has vram of 512, with 503mb available according to PS. In preferences-performance, "use graphics processor" is checked. In the advanced button, "use graphics processor to accelerate computation" is checked, but "use openCL" is grayed out. I've tried unchecking it, restarting the program, and then turning it back on, along with all other forms of "turn it off-turn it back on". The screen resolution is 1366x768, if this matters.
Here are the specifics:
Adobe Photoshop Version: 13.0 (13.0 20120315.r.428 2012/03/15:21:00:00) x32
Operating System: Windows 7 64-bit
Version: 6.1 Service Pack 1
System architecture: AMD CPU Family:15, Model:0, Stepping:1 with MMX, SSE Integer, SSE FP, SSE2, SSE3, SSE4.1, SSE4.2
Physical processor count: 4
[code]....
This graphics card should be enough to work with the 3d of PS, but it isn't, and I've looked at everything that I can find trying to figure this out.

From the Nvidia web site it says that the GeForce GTX 560 Ti supports: DirectX 11 > 3D Vision > PhysX > CUDA > SLI >
301.24 drivers have been used and have downgraded to 296.10 to see if that would work, but it didn't.
When I check the performance tab under Advanced it shows that the OpenCL option is grayed out. When I check the Sys info log it also shows that OpenCL is Not availible (included below).
Why is this and when will it be fixed? Now that CS6 is shipping it should be working.
