FFmpeg is CPU intense

[Sneffel]

FFmpeg uses too much CPU, all it can have to the ceiling, even 90% of the total. I'm on a commercial build of AMD 64. It makes the PC freeze and crash. How can I limit the processing to 50% of the CPU?

I'm calling auto-editor like this:

@echo off set "input_file=%~1" "C:\Users\Username\AppData\Local\Programs\Python\Python312\Scripts\auto-editor.exe" --margin 1s,2sec --no-open "%input_file%" --my-ffmpeg %ffmpeg_threads% -c:v libx264 -b:v unset --extras "-preset slow -crf 22" pause
