![]() New in Premiere Pro CS5 are little icons to the right of some effects that tell you whether they are accelerated, or work in 32-bit or YUV space. ![]() The little icon on the left in Premiere Pro CS5 tells you that the effect is GPU accelerated.īasically, that means that CUDA lets software developers such as Adobe access the graphics card to accelerate certain functions, such as preview and rendering. CUDA is the computing engine in Nvidia graphics processing units or GPUs that is accessible to software developers through industry standard programming languages.”įigure 1. “CUDA (an acronym for Compute Unified Device Architecture) is a parallel computing architecture developed by Nvidia. Depending upon where you look, GPU acceleration has been described as part of the Mercury engine, and has also been called CUDA technology, since that’s Nvidia’s brand for the underlying technology. The second component, GPU acceleration, only works if you have a supported Nvidia graphics card in your computer (check the Adobe website for compatible cards ). Yes, you can only run CS5 on a 64-bit system (as has been reported for awhile now) and you’ll need gobs of RAM-I’d say at least 16GB, perhaps as much as 24GB-to really see the benefits. Briefly, the Mercury Engine is a brand assigned to a collection of three software improvements: 64-bit native code, the greater memory addressing that this enables, and superior multiple-core CPU use. What produces this speed increase? Three components: the Mercury Playback Engine graphics processing unit (GPU) acceleration and a new, much higher-performance H.264 codec from third-party codec vendor and Adobe supplier MainConcept. At the risk of adding to the iPad effect, that’s simply astounding. Specifically, in one of my tests, which involved a 20-minute ballet audition video, rendering time of the 7D footage dropped from 84:45 (min:sec) to 3:57 on a 12-core HP Z800. Specifically, if you’re working with H.264-based footage, such as footage shot with the Canon EOS 7D or AVCHD camcorders, you could see a drop in rendering time of as much 95 percent. Adobe Story, the start of the script-to-screen metadata workflow. CS5 sings on a multicore computer such as HP’s 12-core Z800. The little icon on the left in Premiere Pro CS5 tells you that the effect is GPU accelerated. The only 2 DSLRs that I'm aware of with "clean" output are the Panasonic Lumix GH2, and the new Nikon D4.Īs mentioned, even if a DSLR camera will put out a good image, you will need a "capture device" with HDMI input such as BMD Intensity or Matrox MXO2 Mini connected to Mac or PC. Do you get a perfect, full-screen image without any overlays or any cropping, and at full quality? My understanding is that they all "dumb-down" the output signal in some regard while recording, unlike video cameras that will all put out a perfect HD image. We're a reseller of the Atomos Ninja portable recorders and this has been a huge issue - DSLR shooters want to use Ninja for the exact purpose you mention, for long, uninterrupted recordings, but the HDMI outputs from those cameras are just not suitable.ĭo this - connect the HDMI out from your camera to an HD display and start recording with the camera. DSLR cameras are notorius for not allowing you to fully turn off info overlays on the HDMI output, or even if you can on your particular camera, the output signal is somewhat cropped or otherwise not a proper HD signal. Please note that I don't believe your camera will put out a proper full-resolution, full-quality HD signal via HDMI while in record mode.
