Some observations regarding VBR 2 pass coding - Bug reports That's what 2 pass (VBR) is for and why you normally choose 2 pass. It first analyses the video for its visual complexity and then adjusts the required bitrate for it. So you can save some filesize. This is not a bug, it is good! Just like one user said: "I don't like using CRF, I can't reach my usual bitrate with it." FFmpeg-users - 2 pass CBR or VBR not really fixing the bitrate?

Either select MPEG-2 in the Add Settings pop-up (the + button) or better CBR (Constant Bit Rate), One Pass VBR (Variable Bit Rate) or Two Pass. If you don't care how big the file is but want to encode quickly, use One Pass CBR.
And, theoretically speaking, an interesting variation of 2 pass encoding could be to encode first pass using a constant quality mode (user selected) and then, once scene changes and bitrate budgeting is performed, the second pass could be a VBR encode taking into account the information from the first pass. VBR 2 Pass vs VBR 1 Pass vs CBR : letsplay - reddit The difference between VBR 2 and 1 pass differs based on what codec and encoder you're using.
