Question

How to utilize intel quick sync in premiere cs5 export to H264 (sandybridge laptop)?

As I have a sandybridge laptop on order (Lenovo w520), I wonder what would be the best way of exporting the timeline utilizing the Intel Quick Sync option. Cyberlink has a videoconverter program that utilizes the Quick Sync option. Would I try to use a video frame server, an uncompressed video output or is there any development completed using the SDK? There are indications that the quick sync option may have better quality and half the render time compared to an Nvidia graphic card. Thanks.

    Tried to run the PPBM CS5 under Intel sdk and the discrete NVidia CPU. The benchmark didn't run under intel sdk and the H264 test was not identical as the output was rendered as progressive instead of interlaced. However, just looking at the render times in AME for the different tests I noticed a 15% improvement for the H264 test, identical times for the Mpeg2_dvd test and 4% slower result under the disk speed test. Perhaps other bottlenecks of AME do not allow for taking full advantage of the speed improvement under intel sdk as seen in the previous testing where I compared a simple encoding of HDV material.

    Just finished encoding a typical project for me using the intel sdk and the discrete GPU with AME. This was a 60 minutes multicam project with three HDV streams, color corrections, transitions, and resizing. Under the discrete GPU, it encoded to H264 in 43 minutes. Using the Intel sdk, 33 minutes, about 25% faster.

    Yes, QuickSync does make a difference in CS5.x performance, especially on laptops. Most desktop PCs, however, have much more powerful discrete GPUs than their laptop counterparts.

    Unfortunately, Premiere Pro does not support QuickSync at all. Not even the latest CS5.5 supports QuickSync. (Nor will Adobe support QuickSync in any foreseeable future version of Premiere.) What's more, QuickSync supports only the integrated Intel GPU and is completely disabled with a discrete GPU installed.

    Furthermore, only the H61, H67, B65, Q65 and Q67 chipsets currently support QuickSync. The P67 chipset does not support QuickSync at all because a discrete graphics card is required for that chipset. And the few results that I've seen in the PPBM5 results list of systems that use H67 motherboards show abnormally slow performance in MPE GPU mode when Nvidia cards are used in those systems. In other words, QuickSync is currently of little (if any) use whatsoever to Premiere Pro because the program does not support the feature at all in the exact tests used in PPBM5.

    And the only reason why a given Sandy Bridge system is faster with QuickSync and integrated Intel graphics than an otherwise identical system with a discrete Nvidia graphics card is because the H67 chipset gimps the PCIe-x16 graphics card slot: That slot only runs in PCIe-x1 mode instead of the correct x16 mode by default. Otherwise, a P67-based system with a discrete Nvidia GPU far outperforms the H67 setup with integrated Intel graphics.

    And how 'bout the plugin developed by Intel for Premiere Pro:

    http://software.intel.com/en-us/articles/adobe-premiere-propremiere-elements-encoder-plug-in-using-intel-media-sdk-and-intel-quick-sync-video-technology/

    The description says with a prototype plug-in Premiere Pro supports Intel Quick Sync technology.

    I haven't yet have my Sandy Bridge setup so I don't have any first hand experience.

    As far as chipsets are concerned the new Z68 chipset sort of combines the advantages of H67 and P67, you can use a PCI-E graphics card and can overclock as in P67 but also the GPU integrated into the CPU can be harnessed.

    Cheers,

    MPE does not use the GPU for encoding. It uses it for other operations such as scaling and rendering out effects. What was your resolution settings for export and did you have any effects on the timeline or did you just run a simple transcode with the AME?

    Paramita7 said the following and I simply would like to be able to do the same with AME.

    "AME can be started in either the integrated GPU (Intel Sandy Bridge) or the hardware Nvidia GPU."

    Is there some startup parameter that I need to change to do this?

    Thanks
