Hey there!
I suggest sharing the experience of Dain-app tests in this topic to identify the optimal settings. So that beginners do not to sort through all random combinations of settings through long experiments, and don't use obviously ineffective examples.
I found out about this wonderful application 3 days ago. And starting the selection of optimal settings for fast rendering, I proceeded from the recommendations of users from web sites.
Dain-app has recommended default settings for Section Size:480px and Section Padding:150. I also saw custom examples on the forum, for example 400x100. And when I tried different settings, I basically changed only the value of Section Size, but i don't changes Section Padding, i left it by default.
As it turned out, I underestimated this setting, today's experiments have made me understand that rendering can happen much faster if you set the Section Padding value to 0.
*At least in the configuration of my computer, interpolation has become significantly faster.
My PC specs: Win 10 / RTX 2080 Ti Strix OC 11Gb (EK water cooled) / Ryzen 3970x / 128 RAM / m.2 970 Evo Plus SSD
For the test, several short video clips with different resolutions were choice. Each video is 0.5 seconds long and consists of 15 frames (30fps).
Below I will give the results of my tests.
// test video resolution //
/ @ Section Size x Padding in px / total rendering time / (mb VRAM usage in interpolation process) / CPU load / GPU working frequency /
***I was interested to see how changing the split frame into sections settings will affect the load and distribution of system resources.
