Vouk 2.2.0 REALLY Slow, 1.1.3 Still Quick (NVENC/HEVC h.265)

  • Hey gang -

    I have both 2.2.0 and 1.1.3 installed with Premiere, and I'm attempting to export a 25Mbit/sec 4K/59.94 video that's about 8 or 9 minutes long. I'm doing so with the HEVC hardware encoder on my 2080Ti card. When I use the older 1.1.3 plugin, it takes about the amount of time I'd expect; if the video is time t, the encoding/exporting is about time t. But with 2.2.0, when I hit the export button, it takes upwards of 2t if not longer.

    I usually cancel it out, which is why it doesn't run that long. It feels like it's trying to do a 2-pass for some reason, but I don't see that option anywhere in the plugin menus.

    I'm sure I'm doing something stupid here; any guess as to what it is?


  • There are many users reporting this. But I never found out why it is like that.

    When i use my test project (2048x1152 / h264_nvenc / default) version 2.3b2 is even faster than 1.1.3.

    All I know it has to do with the time premiere needs to render the raw frame (vRender). Did you try the VRPT tool on the project? Does that finish faster or slower than 1.1.3?

  • I compared the project files and made them almost identical. But that did not fix it.

    In theory we do not need to think about v2 here. The first goal is to make VRPT as fast as v1.1.3 (or find out was has changed).

  • I didn't manage to run the test all the way through. I started it up, saw that the estimated time went up to somewhere around 1.5t and let it go for a minute or two, then killed it. In other words: it's slower than 1.1.3, but a little faster than 2.2.0.

  • I can confirm what jasonvp wrote.

    I did tests with a 1-minute sequence (3840x2160 60p, cineform codec source; no fx or anything).

    With 2.2.0 (and 2.2.3) it exported in around 2:30 (basically 2.5:1 time ratio)

    Then I ran VRPT , and it completed with about 1.6:1 ratio:


    Finally, I've tried 1.1.3 and it finished in 51 seconds (0.85:1).

    I re-ran this several times, and even with different compression/profile settings, these numbers remained pretty much the same.

    My specs are i7-7700k@stock, 32gb ram, 1080Ti, win10. Source/export on fast disk (no bottlenecks).

    Thanks for your work and it's great projects like these exist; the speed of 1.1.3 export is a real incentive to use it over CPU encoding when time is a priority.
