Andrea, If I remember correctly, rendering is not threaded (I will verify with GG later when he gets back from a bike ride). When gg does a 2 hour movie rendering, he almost always uses a local render farm. This is described in 6.4.5 BUT I just noticed that an image showing this that was in Features5.pdf was eliminated (probably by me at some time). I will send a copy of the png to you since it shows a 16 core setup for a "root" user (the 400 range ports work only for root and I have not personally tried the 1025 range for ordinary user). In 6.4.1, just follow the basic steps 1-7 and skip step 2 since there are no clients. I have not tried the Shell Script RenderMux in a long time, but Olaf fixed this for us awhile back and it was working perfectly then.

I have a CPU 8 cores / 16 threads, but the final rendering uses only one core. I tried with mp4/h264-5; webm/VP9; mkv/h264-5 e Prores. A 45 min video takes 3h 30m. I tried adding the parameters "threads=15", "wpp" which should be active by default and "frame-threads=3"; but the result is the same. On average I do 15 fps. Using h264-5 with nvenc takes 1h20m; but the CPU still uses only one core. On average I make 115 fps. Using an external engine (handbrake, which uses ffmpeg) you can use both the Cpu and the GPU; the rendering will take 10m! (but with lower quality).
Since I'm compiling CinGG (note: all threads are used for compiling), maybe I need to enable some flags or something like that? Are there any customizations to do? Or should I set something in the operating system?
Another question: How do you configure the render farm to use only the local CPU cores? -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
