one core. I tried with mp4/h264-5; webm/VP9; mkv/h264-5 e Prores. A 45<br>
min video takes 3h 30m.<br>
I tried adding the parameters "threads=15", "wpp" which should be<br>
active by default and "frame-threads=3"; but the result is the same.<br>
On average I do 15 fps.<br>
Using h264-5 with nvenc takes 1h20m; but the CPU still uses only one<br>
core. On average I make 115 fps.<br>
Using an external engine (handbrake, which uses ffmpeg) you can use<br>
both the Cpu and the GPU; the rendering will take 10m! (but with lower<br>
quality).<br>
<br>
Since I'm compiling CinGG (note: all threads are used for compiling),<br>
maybe I need to enable some flags or something like that? Are there<br>
any customizations to do? Or should I set something in the operating<br>
system?<br>
<br>
Another question: How do you configure the render farm to use only the<br>
local CPU cores?<br>
