Graphics card with at least 4GB of memory (VRAM). Translating that to the real world, tasks such as color adjustments and image size scaling would be GPU accelerated, but H.264 encoding would not. In a quick H.264 export test performed by Adam Patrick Murray, PCWorld’s lead video director, on a system with an Intel Core i7-6900K and a GeForce RTX 2080 Super, activating GPU encoding ramped up GPU utilization—as you’d expect—and cut the render time in half. Once your account is created, you'll be logged-in to this account. I am facing a huge performance issue while using Adobe Premiere Pro. And noticing very poor performance issues. How well does this feature work, and is it faster than the previous hardware decoding that utilized Intel Quick Sync? Note that Premiere Pro can also be set up to use both GPUs, one GPU, or only the CPU. For example, the internal PCIe flash drive in a new Mac Pro is extremely fast: roughly twice as fast as a top-of-the-line SATA-connected SSD. On the Adobe site, it lists a GPU as "Optional". Just painful to use and look at. On top of that, it allows you to edit videos simply, like cut, merge, crop, stabilize and denoise 4K videos shoot by iPhone, GoPro, DJI and 4K camcorders. I have the latest radeon series with latest OpenCL support. Finally, open the Project Settings in Premiere Pro and change the Video Rendering and Playback popup to CUDA. Yes for Premiere Pro, but not so much for After Effects. GPU acceleration isn’t new to Premiere, you can use it with the Mercury Playback Engine for decoding video as you work on the timeline. Save the text document and open up Adobe Premiere. It so happens that Adobe Media Encoder (AME) and Premiere Pro both share the same Mercury Playback engine code. Adobe is terrible. With the new Premiere Pro 14.2, video creators gain massive time-savings with new GPU-accelerated encoding. A graphics card is … Poo2; Oct 14th 2018; Poo2. We also get your email address to automatically create an account for you in our website. “We work closely with NVIDIA to deliver GPU-enhanced features that help make Adobe applications more robust and powerful,” says Sue Skidmore, head of partner relations, Adobe Creative Cloud Video. Filmmakers go-to destination for pre-production, production & post production equipment! If you don't see your device listed here, it is because it has not been tested with Adobe Premiere Elements. Adobe has released important information regarding support for GPU acceleration with CUDA and Apple Metal in future releases of Premiere Pro CC. Keep in mind that a computer is not a single chip; it’s an entire interconnected system. Adobe and NVIDIA have optimized Premiere Pro for the built-in NVIDIA hardware encoder on NVIDIA Quadro and GeForce GPUs. Plus, don’t forget the file system overhead of reading the source file(s) and writing the final output file – this can get significant with larger files such as those saved uncompressed or using camera raw. My laptop is an old MSI gaming laptop, Windows 10, using premiere pro cc 2017.0 and I've set NVIDIA to be used for global application setting (including premiere pro). Speaking of which, Dell also redesigned its Precision workstation lineup, with the Dell Precision 5750 joining the Precision 7000 series in the RTX Studio program. Adobe released updates to a number of its audio and video applications last week, including Premiere Pro, Media Encoder, After Effects, and Audition. Premiere CS6 utilizes the Mercury Playback Engine to take advantage of the video card to vastly improve both the performance and quality of certain features, but there is currently very little information available regarding the performance of different video cards. Premiere does its best to realtime preview your timeline so that you don’t have to transcode your videos or wait on render previews. Timeline is choppy, slow exports, etc etc etc. This frees up speed for the CPU resources and it removes the CPU bottleneck. NVENC is designed to accelerate video encoding by using the GPU hardware only to export H.264 and HVEC (H.265) video files. Copyright © 2020 IDG Communications, Inc. Yes for Premiere Pro, but not so much for After Effects. Adobe Premiere Pro to use GPU acceleration for faster encoding Christopher Nohall May 19, 2020 Featured Tech News , Graphics , Software & Gaming Graphic processing units can be … I will stick to CPU acceleration with AMD Ryzen :D. The takeaway is: A good GPU is almost essential for software that is accelerated by it (such as Adobe Premiere Pro and Media Encoder), and two GPUs can indeed yield appreciable additional speed gains – but when you start going beyond that, the rest of the system may hold you back from enjoying the gains you might expect. It’s a dedicated piece of hardware found only on NVIDIA GTX and RTX graphics cards. The power of AI comes to video with Adobe’s release of a new GPU-accelerated AI feature in Adobe Premiere Pro called Auto Reframe. While working with Adobe to update their Hardware Performance White Paper (which contains tips for non-geeks to optimize their hardware based on the different needs of Adobe’s video software), we learned that not only can Premiere Pro take advantage of both GPUs in the new Mac Pro, you can also install multiple GPUs in an older generation Mac Pro as well as Windows workstations to get similar or even greater performance gains. Adobe Premiere Pro CC is the industry's leading video solution, leveraging NVIDIA GPUs to accelerate performance for real-time editing on your most challenging workflows and even with 8K video. My laptop is an old MSI gaming laptop, Windows 10, using premiere pro cc 2017.0 and I've set NVIDIA to be used for global application setting (including premiere pro). I am not into running games on my computers, so I have no idea how much ram your video card would need for the different games. Save the text document and open up Adobe Premiere. When rendering the CPU is the only working also. Premiere Pro is engineered to take advantage of the GPU. The top of the range Intel Core X-Series processor is the very best option for Premiere Pro users featuring 18 cores . Here’s how to solve it. We’ve seen a monumental change in the industry in the last 30 days. It uses Adobe Sensei AI to identify and track the most relevant elements in a video — be it a snowboarder or race car — and intelligently reframes video content for different aspect ratios. C:\Windows\System32\cmd.exe /c start "Adobe Premiere Pro CC" /affinity FFFFFFFF "C:\Program Files\Adobe\Adobe Premiere Pro CC 2015\Adobe Premiere Pro.exe" This is my shortcut to use *all* cores (/affinity FFFFFFFF). NOTE: These recommendations are for Adobe Premiere CC, CS6, CS5.5 and CS5 only. This may change in the future (and you can make GeForce cards work fairly easily), but for now if you want 100% support from Adobe for Premiere … You definitely want to be editing from a computer that has an SSD. Premiere will then use the GPU for what it uses a GPU for ... and when it gets to something that uses one of those effects. Hello. Today, Adobe officially rolled out hardware encoding support for Nvidia and AMD GPUs in Premiere Pro, After Effects, and Adobe Media Encoder, letting you lean on the power of your graphics card to speed up H.264 and HEVC video exporting. “For the first time, video editors and motion graphics artists can import and edit ProRes RAW files in Windows with no need to transcode. Go to the “Project” menu Project Settings General. There are a lot of issues you'll probably face if you have AMD Radeon Graphics on your video editing PC. Note the highlighted estimated time to completion. Under “Video Rendering and Playback” click the dropdown box where it says “Renderer” and choose “Mercury Playback Engine GPU Acceleration”. Your GPU is doing all it can, it's just there isn't much for it to do and what it can do its built specifically for and so the task is quite easy. The results are staggering. This is accelerated by CUDA, available exclusively on Nvidia GPUs.”. While these updates bring a healthy number of individual improvements across the lot, it was the mention of faster GPU encoding in Premiere Pro and Media Encoder 14.2 that caught our eye first. Today's GPUs (2nd half of 2012) can and many do comply with IEEE 754, which is a standard for Floating Point arithmetic computation, but not everyone does. Of course, you can add an AMD video card to an older generation Mac Pro and also see dramatic performance gains; we're looking forward to getting data on their new W9100 card (and will add it to this article once we get them). CPU is much more important in Premiere, only certain effects benefit much from GPU use and GPU use will rarely get above 5-15% in most cases. They also added a Fusion-io PCIe flash drive card to create their highest-end configuration. I am a Premiere Pro CS6 user as well and the GPU acceleration does make a difference. If you’re hoping to hop onboard the GPU encoding bandwagon, Adobe recommends using a graphics card with at least 4GB of onboard memory for 1080p videos, 6GB of VRAM for 4K videos, or 8GB or more of VRAM for higher-resolution tasks. In the latest version of Premiere Pro, Adobe has added support for GPU-based H264/H.265 (HEVC) hardware decoding with both NVIDIA and AMD GPUs. NVENC is designed to accelerate video encoding by using the GPU hardware only to export H.264 and HVEC (H.265) video files. He tweets too. Again, normalizing to the 4-core dual A300 2013 Mac Pro as being the performance baseline: Not meaning to bash the new Mac Pro – indeed, we’re considering getting one for Trish, who has been surviving with a 2008 vintage 8-core Mac Pro – it is possible to build out a Windows system to exceed the performance of a 2013 12-core Mac Pro with dual A700s when it comes to running certain representative tests using with Adobe Premiere Pro. Adobe Premiere Pro CC CPU & GPU Performance Page 2 : GPU Performance ... it is clear that for generating previews there is rarely a need to use a dual GPU … First off, you want to make sure you have at least 8GB of RAM (I’d recommend even 16GB as a minimum) and a fast graphics processing unit (GPU). PCWorld |. There is a historical reason for this: GPUs have favored speed over accuracy. (Optional) Multiple GPUs, including eGPUs, can be used to speed up rendering and export. Adobe Announces Support Changes for CUDA and Apple Metal in Future Release in Premiere Pro. When you login first time using a Social Login button, we collect your account public profile information shared by Social Login provider, based on your privacy settings. Of course, Premiere Pro is rarely an island; sometimes you need to create assets in After Effects, or convert to a specific file format using Adobe Media Encoder. Understand the GPU and GPU driver requirements for Premiere Pro for the October 2018 and later releases of Premiere Pro (version 13.0 and later) By the way, that’s pretty good scaling of performance for dual GPUs; I expected more losses due to data transfer overhead. The results are staggering. Note: When you purchase something after clicking links in our articles, we may earn a small commission. Also remember that ray-traced 3D in After Effects is also accelerated using NVIDIA’s CUDA (but not OpenCL). Boutique system builder Puget Systems benchmarked Premiere Pro’s new NVENC encoding support while it was in beta, however, and found “this feature resulted in between a 2-4x improvement in export times depending on the source codec with a minimal (if any) decrease in video quality.”. Here’s how to solve it. PCWorld helps you navigate the PC ecosystem to find the products you want and the advice you need to get the job done. Adobe Premiere Pro is probably the best video editing software for 360 videos because of its ever-growing list of capabilities. Basically, you need a CPU that supports Quicksync (pretty much anything with onboard graphics) and you need to have the onboard graphics enabled in the BIOS. Encoding and decoding different video formats currently runs on the CPU (although the prep for encoding does use the GPU with OpenCL when rendering out to final). But it does have bugs, one of which is that sometimes, it can’t find your GPU (graphics card). Entender quais são os requisitos de GPU e Driver da GPU para o Premiere Pro para as versões de 2018 e posteriores do Premiere Pro (versão 13.0 e posterior) The GPU is used for onscreen rendering and export, priority areas for video production. So don't expect butter smooth playback if iGPU is disabled. I want to use Nvidia's GPU as my primary GPU but somehow there is no any option to do so. I’ve just got Premiere Pro CC and H.264 encoding doesn’t use any GPU activity im looking in Catalyst. Applications don’t automatically detect and use multiple GPUs; the drivers must support them, and the software must be written to exploit them. I just realize how washed out and blurry the Adobe Reader is. Content creators, start your engines. I have also been monitoring the GPU … The power of AI comes to video with Adobe’s release of a new GPU-accelerated AI feature in Adobe Premiere Pro called Auto Reframe. Encoding and decoding different video formats currently runs on the CPU (although the prep for encoding does use the GPU with OpenCL when rendering out to final). Welcome to a special podcast series from Steve Hullfish and ProVideo Coalition! Unlike Premiere Pro CC, however, DaVinci Resolve software does have some effects that predominantly use the GPU resources once being applied to your edit. In Premiere Pro, graphics card is used to accelerate encoding times and preview. Keep in mind that a computer is not a single chip; it’s an entire interconnected system. Keen to try out all the new features? While rendering / exporting, Intel's GPU is always at 8-10% while Nvidia's GPU is at 1-2%. Senior editor Brad Chacos covers gaming and graphics for PCWorld, and runs the morning news desk for PCWorld, Macworld, Greenbot, and TechHive. Furthering the “it’s the system” theme, NVIDIA ran a further series of tests including a variety of configurations of HP Z420, Z620, and Z820 Windows machines with their Quadro K5000 and K6000 cards (note that with both AMD and NVIDIA, the higher the model number inside the same family, the higher the performance). CUDA is selected in premiere pro and also in the NVIDIA configuration. “With NVIDIA encode acceleration in Adobe Premiere Pro, editors can export high-resolution videos up to 500% faster than on CPU. The intent of this article was not to sway you to use FCP, Premiere Pro, or Avid for that matter, nor to make you choose between MacOS or Windows or between AMD and NVIDIA; there are numerous reasons why any individual chooses the computer they do. Nvidia says the newfound support for the NVENC hardware encoder in GeForce and Quadro GPUs can allow video editors to export videos up to five times faster than CPU rendering alone. Introduction . 5. During real-time playback, only one GPU is used; Adobe has found that in this time-critical application, the overhead required to swap data between multiple GPUs more than cancelled out any speed gains. A typical example in that regard is the Noise Reduction filter that is only available in the paid version of the platform. The GPU only does specific things, like the LUT you applied, but that's crazy easy. In previous versions, hardware decoding was supported, but was only available if you had a CPU that included Intel Quick Sync. I recently updated a 2017 Apple MacBook Pro to the larger 2019 model. You would need to look at a third-party solution such as a Fusion-io in a PCI Express slot to get similar performance out of a different computer. It’s expected that Apple’s own Final Cut Pro can; many seem to assume that Adobe’s Premiere Pro can’t – but that’s not the case. ... A community-run subreddit for Adobe video editing apps including Premiere Pro, Premiere Rush, Premiere Elements, and Media Encoder. Keep in mind that a computer is not a single chip; it’s an entire interconnected system. In Premiere Pro, graphics card is used to accelerate encoding times and preview. NVIDIA GPUs now have NVENC, which stands for N VIDIA’s V ideo ENC oder. Adobe Premiere Pro runs perfectly well on a 4 or 6-core budget processor option when working with lower resolutions, but you may be left wanting a bit more power at times. In the latest update of Premiere Pro, Adobe has added GPU-accelerated hardware decoding for H.264/HEVC media (not to be confused with the GPU encoding we got back in April). NVIDIA GPUs now have NVENC, which stands for N VIDIA’s V ideo ENC oder. There is a historical reason for this: GPUs have favored speed over accuracy. Reactions Received 6 Posts 110. In their case, make sure you buy that system configured up front the way you plan to use it. It should be stressed that this is not an overall comparsion of OpenCL versus CUDA; just one manufacturer's implementation of both on their own hardware. Adobe and NVIDIA have optimized Premiere Pro for the built-in NVIDIA hardware encoder on NVIDIA Quadro and GeForce GPUs. For Adobe Premiere users, if you get any trouble with GPU acceleration, check the hardware info with VideoProc to solve it pertinently. Apple’s inclusion of dual GPUs in every model of their new Mac Pro has caused a bit of a stir (and confusion) among video editors wondering if their NLE of choice can take advantage of them. We’d like to share that information with you here, hopefully boiling the raw numbers down to a few takeaways for you to consider when choosing or configuring a system. With the new Premiere Pro 14.2, video creators gain massive time-savings with new GPU-accelerated encoding. Having 2 GPUs is a huge problem as Intel's GPU is not allowing Nvidia's GPU to function properly. Although the new Mac Pro is indeed a very slick, well-integrated machine, it is possible to recreate essential parts of its magic by upgrading existing computers. Their results are below, with the charts being adjusted to show a new 4-core Mac Pro as being the baseline (1x performance): The takeaway here is that although a single K5000 does not quite elevate an older 12-core Mac Pro the level of a new base model 4-core Mac Pro, under some circumstances adding a pair of K5000s can elevate it beyond the speed of even a new 12-core Mac Pro. Does Premiere actually use nvidia/amd gpu for DECODING? Having 2 GPUs is a huge problem as Intel's GPU is not allowing Nvidia's GPU to function properly. It uses Adobe Sensei AI to identify and track the most relevant elements in a video — be it a snowboarder or race car — and intelligently reframes video content for different aspect ratios. 6. But it does have bugs, one of which is that sometimes, it can’t find your GPU (graphics card). 1. The estimated time to completion cuts in half. Student. You can get a significant speed boost using a variety of hardware solutions. Adobe has released important information regarding support for GPU acceleration with CUDA and Apple Metal in future releases of Premiere Pro CC. We just wanted to present the facts and dispel some confusion around getting the most out of Adobe Premiere Pro on a variety of systems, including the new Mac Pro as well as other upgraded systems. So, we started out looking at Assimilate Scratch in our last article, where we looked at creating a new... © 2020 ProVideo Coalition, a Moviola Company. (R370) “””My understanding is that the stock codecs are not GPU accelerated, “” Ferreira’s first test was just a straight-up 10 minute 4K video without any effects or graphics. You also should know that solid state drives (SSDs) are much faster that than hard drives that depend on a spinning disk. “Also included in today’s release is support for Apple’s ProRes RAW in both Premiere Pro and After Effects,” Nvidia says. Here are my recommended laptop computer systems for both Mac and PC users. Adobe Premiere Pro uses a single GPU during playback and multiple GPUs for other tasks such as Render In to Out and for export. We’re already seeing it available on our systems. On top of that, it allows you to edit videos simply, like cut, merge, crop, stabilize and denoise 4K videos shoot by iPhone, GoPro, DJI and 4K camcorders. If you rely on this particular feature, it may sway your decision on how to configure your machine – whether you run MacOS or Windows. Read our, Learn more about PCWorld's Digital Editions, [ Further reading: Best graphics cards for PC gaming ], Nvidia’s creation-focused RTX Studio laptops, redesigned its Precision workstation lineup. Premiere Pro CC can employ both of these GPUs for rendering and exporting. The devices listed in this document have been tested for Adobe Premiere Elements. Only Intel's iGPU can be used for that. 5. All Rights Reserved. Now, you can use the GPU to speed up your exports. I don't know what to do. A typical example in that regard is the Noise Reduction filter that is only available in the paid version of the platform. Scroll down a bit and you will see the instructions for "unlocking" the card for use with Premiere Pro CS6. Adam reports that you can’t use GPU encoding with two-pass VBR (variable bitrate), only one-pass VBR or CBR (constant bitrate). If you’re using an AMD card or chips, this setting would be OpenCL. I want to use Nvidia's GPU as my primary GPU but somehow there is no any option to do so. Adobe released updates to a number of its audio and video applications last week, including Premiere Pro, Media Encoder, After Effects, and Audition. With 2 E5 2670 Xeons, you have 16 cores, plus 16 logical ones that amounts to a total of 32 CPUs. It comes with swanky Quadro RTX 3000 graphics and the free three-month subscription to Adobe’s Creative Cloud common to all Studio notebooks. Adobe Premiere Pro CC is the industry's leading video solution, leveraging NVIDIA GPUs to accelerate performance for real-time editing on your most challenging workflows and even with 8K video. level 2. Of course it came pre-loaded with Catalina. Encoding and decoding different video formats currently runs on the CPU (although the prep for encoding does use the GPU with OpenCL when rendering out to final). Adobe Premiere Pro is probably the best video editing software for 360 videos because of its ever-growing list of capabilities. Your mileage will vary depending on the workload, however. Running on a Windows 7 computer with dual 2.7 GHz Intel E5-2680 CPUs, 32 GB of RAM, and a pair of SSDs, the software-only render took 136:22 (136 minutes and 22 seconds). Adobe's Premiere Pro finally supports hardware encoding support for Nvidia and AMD GPUs, letting your render H.264 and HEVC videos much faster than on the CPU alone. For example, NVIDIA ran their own tests comparing a variety of configurations of the new Mac Pro (4-core with A300 GPUs, 8-core with A500s, and 12-core with A700s), with an older (2010) 12-core Mac Pro that has been upgraded with one or two of their Quadro K5000 video cards as well as a fast Samsung SSD. It does not use the GPU … By entering your email, you agree to our Terms & Conditions and Privacy Policy. Premiere Pro supports both, but in the case of NVIDIA GPUs, you may see a roughly 30% to 40% performance benefit to running then in CUDA mode over OpenGL: To use CUDA in these situations, Mac users must make sure they install both the latest Quadro driver for your NVIDIA video card, and then the CUDA driver as well – the CUDA driver is not installed by default; you need to do it yourself to realize this speed increase. Putting numbers to the theory, AMD ran some tests rendering a Premiere Pro sequence through AME for output. It’s a dedicated piece of hardware found only on NVIDIA GTX and RTX graphics cards. For Adobe Premiere users, if you get any trouble with GPU acceleration, check the hardware info with VideoProc to solve it pertinently. Premiere Pro does not use the GPU for H.264 decoding/encoding, it uses Intel Quicksync. Elevate Editing Workflows with GPU Acceleration. To keep things straight as we get deeper into this, know that AMD APUs and GPUs (FirePro and Radeon) employ the OpenCL standard. And when we say speed up, we mean speed up, as you can see in Adobe and Nvidia’s comparison graphs below. You will render faster with more cores. By taking advantage of NVIDIA’s NVENC tech, Premiere can use GPU acceleration to speed up the export process for H.264 and H.265 files. I am a Premiere Pro CS6 user as well and the GPU acceleration does make a difference. For Nvidia GPUs, that would be CUDA of course. Installing one AMD W9000 into that computer dropped the render time by more than a factor of ten to 11:31; replacing it with their new W9100 shaved it to 10:45. Production During a Pandemic: Working as a COVID 19 Compliance Officer for a Film Production, Insights and Advice from a COVID-19 Compliance Officer for Pre-production and Production, Aging an actor with Adobe Sensei and Mocha Pro 2021, Reviewing The DZOFilm 10-24mm T2.9 M4/3 Cinema Lens, Review: Smart V2M mobile audio interface with 2 lav mics for USB and Lightning, 16″ Macbook Pro Video Export Performance Tests, Voices From Sundance: “Spree” Editor Benjamin Moses Smith, Learn Assimilate Scratch – Audio Syncing and Basic Conforming. That’s a big win for Nvidia’s creation-focused RTX Studio laptops. GPU acceleration isn’t new to Premiere, you can use it with the Mercury Playback Engine for decoding video as you work on the timeline. While neither AMD nor NVIDIA has released new consumer GPUs since our last Premiere Pro GPU roundup 10 months ago, there are a number of other factors that have changed since then. However, even with a fast computer and GPU, sometimes what you have going on in your timeline is still too much to handle and you … A graphics card is practically a requirement for editing 360 videos on […] So don’t forget about how much ram the video card has when you are purchasing a new video card for use with Adobe Premiere. Note that Premiere Pro can also be set up to use both GPUs, one GPU, or only the CPU. When it comes to running Premiere Pro on a system with NVIDIA GPUs, an additional choice is whether to use the OpenCL or CUDA languages (AMD cards or chips only employ OpenCL and not CUDA). At the bottom of here lists the cards they fully support. [Case Mod] Operation: The Division --- … The good news here is that you can upgrade existing machines to get performance that competes with the lastest machines, if that's how you want to spend your money. Create a new Project. It was scaled down to a 1080p 24 fps HD frame size (remember that scaling is also GPU accelerated), and encoded to the H.264 format using two pass VBR (variable bit rate), which is a CPU-only task. CrossFire can be set up to present multiple GPUs as a single logical GPU and for that case, Adobe Premiere Pro treats it as a single GPU. Today's GPUs (2nd half of 2012) can and many do comply with IEEE 754, which is a standard for Floating Point arithmetic computation, but not everyone does. Elevate Editing Workflows with GPU Acceleration. On the 8-core new generation Mac Pro, the performance gains were even more dramatic: 7.6 to 8.4 time faster with a single GPU, and 13.9 to 14.1 times faster with both GPUS being used. I am facing a huge performance issue while using Adobe Premiere Pro. Adobe explained to us that the performance gain from GPU-assisted rendering in AME is dependent upon the encode job as a ratio of rendering time to encoding time. Scroll down a bit and you will see the instructions for "unlocking" the card for use with Premiere Pro CS6. So im trying to Render some 4K 25FPS footage and somehow the Media Encoder doesnt utilize the GPU, only the CPU which is constantly at 100% Load. In the new 14.2 version, Adobe has added GPU-based hardware encoding that supports most modern GPUs from both NVIDIA and AMD. Adobe and AMD ran a series of tests to see just how much difference GPU acceleration made in the new Mac Pro. Installing additional GPUs did indeed further lower the times, but the CPU-dependent portions of the render – including H.264 compression, as well as file shuttling overhead – become a larger portion of the cumulative time: Two W9100s dropped the render time to 7:11; three W9100s required 6:46; four W9100s required 6:40. Our video director exporting a video using traditional CPU encoding. Just open up Premiere Pro, one of many programs worth paying for. Adobe Premiere does not use dedicated/external GPU to decode h.264 videos.
