Speed in Virtualdub dropped 1/3 of benchmark speed

My source video is 1920x1080, when I ran neatbench5, my highest speed is 33.2 fps. But when I do the analysis pass in virtualdub, I am getting 20 fps, that is 1/3 speed drop. Why is there a huge difference?

The host application is likely losing some time on its processing. Please see this article for details.

Interestingly when I use the NeatVideo's check speed in virtualdub with the clip loaded, the highest benchmark speed I got is 22 fps, which is not far from 20 fps I'm getting. So the neatbench5 app that I used was kind of like a benchmark on different machines overall rather than a benchmark on actual videos.

NeatBench5 uses the default filter settings and the frame size of 1920x1080 with 32-bit bitdepth.

If you use any non-default settings or if your video in VD has different size or bitdepth (which is almost certain because VD doesn't support 32-bit bitdepth), then the Check Speed or Optimize Settings test will show different speeds. Have you run Optimize Settings test?

My video is also 1920x1080, bitdepth is 8, temporal radius is 2.

I ran the optimize test, best speed is 22 fps. But I don't know why the speed is so far off from the neatbench5's default test.

I also don't know. Please post the complete logs of both NeatBench and Optimize.

The quality mode is different. In VD, you use non-default High setting, while NB uses the default Normal setting. That is the most likely cause of the difference of speeds. It should be higher in VD (since it is working with 8-bit data) when all filter settings are equal.

You're right, changing temporal filter quality to "normal" the speed jumps to 36.7 fps.
