Bitrate setting doesn't work correctly on both CBR VBR on 4K test

I'm converting simple 4K X4K raw AVI to mp4 with 10Mbps bitrate for streaming test.
When I set CBR 10Mbps with maximum render setting, I get 300 Kbps..
When I set VBR 10Mbps with maximum render setting, I get 1-1.3Mbps..
Maybe it thinks that's enough, but the gradient doesn't look good as the original source.
Also I need accurate size of bit rate data for my test

Happened to me too. Trying to convert a 4K ProRes 422 HQ file to h264, 40 Mbps, outputs a file with just half the expected bitrate.
