The performance delta between 1 video stream and 2 concurrent video streams when using CPU rendering is what PW would expect - around twice the time for about twice the rendering work. Whether the reason behind this is due to video management, storage, or other issues, is not clear.įor the most common video-editing scenarios, a Quadro K1200 is the perfect graphics card for Adobe Premier Pro The conclusion appears to be that the Mercury Playback Engine itself functions as the performance bottleneck. PW would have expected the much more capable Quadro M4000 to out-pace the more modest Quadro K1200. First, it says that the Quadro K1200 is the right GPU for your Adobe video-editing workstation.
* Rendering time (sec) / sec of video (25 fps) HD video The GPU-accelerated tests ran at the same speed on the Quadro K1200 and M4000.The CPU rendering is faster than the GPU rendering in the MPE when rendering 3 or 4 simultaneous video streams.The MPE performance drops dramatically when a third video stream is rendered simultaneously.
It renders faster than realtime, and it performs at twice the speed of the Mercury Playback Engine using software (CPU) rendering only.
