    adobe mercury playback engine question

    Themis_37 Level 1

      Hi all. Firts of all, sorry for the forum nickname, the registration process drove me crazy with the unavailable names... :-)

       

      I own a post production studio and one of my  workstations is a quad core (9400 Intel cpu) equipped with 4GBs of DDR3  RAM at 1333 MHz. Recently I read about the Adobe Mercury Playback  Engine.I usually work with 720p and 1080i HDV material and often with  1920x1080 at 35 Mbps and also AVC-Intra 100 (100 Mbps). If I install the  Adobe Production Premium suite on the above workstation (under Windows 7  64bit), raise my RAM amount to 8 GBs and also install an Nvidia Quadro  FX 3800 graphics card, how much will my workstation benefit from these  changes? For example, how many video tracks with applied  picture-in-picture effects will I be able to play realtime? Or is the  above graphics card only beneficial when installed in an 8-core Xeon  system?

       

      Thanks a lot in advance

          The Q9400 is not very fast. A certified nVidia card will help with PIP and other supported effects, but the CPU will still be a bottleneck.

           

          If you run the PPBM4 Benchmark test and submit the results to Bill, and possibly to me by PM, you will have in idea of the speed of your own system in comparison to others. With CS4 I expect your system to come up with a score around 110 - 130 seconds, which is more than 3 times slower than the top performing CS4 scores.

           

          Whether the FX3800 would be the best video card for you is not really clear. The new Quadro line based on the Fermi architecture is expected to be announced in june.

           

          Your luck is that HDV, XDCAM-EX and AVC-Intra are formats that are pretty easy on your system.

            Thanks a lot, I will do the test. so if I get it right, what you're saying is that it's a CPU-graphics card combination. I'm guessing with an I7 Extreme Edition (980x) and, say, 8 or 12 GBs of RAM things will be much better, right? I was considering an 8-core Mac Pro but I'd like to have a second, more affordable option...

              In that case an i7-930 is far more affordable, but of course not as fast as the i7-980X, but with proper tuning and some overclocking, the performance is nearly equal, only the price is significantly different.

                I see... So would you recommend I7 980 even for RED material or would an 8-core Xeon be prefered? Do you think in these two cases a Quadro FX 3800 be of more use?

                    This is way off. I suggest you go to the PPBM folder, open the Adobe Premiere Pro Preview Files folder and then open Benchmark.PRV folder.

                    Press CTRL-A and then SHIFT-DEL to delete all preview files. Next open PR and the Benchmark project. Select skip all previews and then render the timeline again. Close PR and run Statistics.vbs again. Only answer the first two questions about location and for all the rest just press Enter.

                     

                    It you now open Output.txt again, you will likely see a render time of around 35 seconds and a total time around 104 seconds. Report these here if you please.
