Rendering on GPU and -c very heavy

[whatforiam]

Is it possible to render via gpu? Write -a "-c:v hevc_nvenc" is not an option, because automatic bitrate detection will then be unavailable, and if you do something like this, the bitrate will be too high for many scenes.

And also, my original video weighs 350mb, and if you run it through -c, then the final weight will be 700mb, it doesn't seem to me that it should be.

I have this command

``` scenedetect -i " " -d 2 -b pyav detect-adaptive -w 0.1 0.1 1.0 0.0 - c 34 -t 2.7 split-video -o "" -a "-c:v libx265 -crf %crf%" -p fast 

Ideally, the rendering would take place on a video card, and the result would be equal to the command that I gave
