Vouk's Render Performance Test

  • This is the result I got with Premiere Pro CS6 (v. 6.0.5) on my main rig - 244 fps @ 1920x1080:



    I also tested a few different encodes of the same files to better examine Premiere's decode speed with VRPT. For that, I created 5 identical timelines each containing 5 identical video clips without audio, effects, or transitions, with identical resolutions and framerates. The only difference between these timelines was video codecs used to encode said clips.

    Original ProRes 444 LOG source footage (avg. 215 Mb/s-) - 48 fps:


    The same footage encoded with HandBrake's Production Max preset (avg. 127 Mb/s) - 78 fps:


    The same footage encoded with HandBrake's Production Standard preset (avg. 55 Mb/s) - 140 fps:


    The same footage encoded with HandBrake's Production Proxy 1080p preset (avg. 19 Mb/s) - 248 fps:


    The same footage encoded with a custom NVENC CQP18 HQ preset in HandBrake (avg. 5 Mb/s) - 356 fps:


    Interestingly enough, despite the fact that ProRes and Production Proxy timelines were the fastest in terms of forward and backward live playback and playhead scrubbing, due to their I-frame-only nature, it was actually much faster to render an NVENC timeline, which was the only one among these timelines to actually contain all 3 frame types (I, P, B). You might think that this was due to disk throughput (the smaller the videos the faster the render), but all these videos were stored on a fast modern SSD with DRAM cache, and the disk load during rendering was fairly low.


    All the above tests were run with Mercury Playback Engine GPU Accelerated (CUDA).

    I did try to disable CUDA, but, I didn't notice any significant speed change when rendering these effectless/transitionless timelines with CUDA disabled.
