What about the default file size and colors of the vulkan output file

I append my test and my preset. I have not color problem.

Yeah, thanks.

Your ffmpeg and ffprobe outputs confirms that the video+audio

input bitrate: 768 kb/s
output bitrate: 2175 kb/s (2176.9)

No rate control settings specified, using fixed QP = 18

As mentioned I tested with global_quality=28 and got much lower output bitrate (file size)

And as Andrew mentioned, the color issue seems to be a bug in the ANV driver.
