Is there any way to add -maxrate control?

Open Lew340 opened this issue 2 years ago • 2 comments

ive been experimenting with a bunch of different ffmpeg filters and can't manage to get max bitrate control working.. e.g. custom ffmpeg filters: -c:v h264_nvenc -qp 12 -maxrate 140M -bufsize 15M

im finding it very difficult to find a balance of good quality without the bitrate being 3-5x what the original recording is. my recordings are around 100-120mb/s because of type of game.

I understand this isnt really your problem, but would greatly appreciate any help or advice. I've been using the dev build.

i was able to somewhat control the bitrate whilst maintaining the best quality with the following:

  • advanced rendering gpu interpolation: true gpu rendering: true gpu type (nvidia/amd/intel): nvidia video container: mp4 custom ffmpeg filters: -c:v h264_nvenc -preset p7 -tune:v hq -rc:v vbr -cq:v 10 -b:v 0 -profile:v high -bf:v 4

still not sure what the optimal way is to do it, but this is something that seems to be working for now

I don't have that much experience in advanced ffmpeg configuration, so I can't really help you sorry. You should definitely be able to do what you're wanting through the custom ffmpeg filters option though 👍
