[FFmpeg-user] Can this trigger VBR encoding for x264, x265, and libvvenc ?

If I set " -b:v 5000k -maxrate 6000k -minrate 4000k " for x264, x265 and
> vvenc, will this enable VBR encoding for these three encoders ?

If "constrained VBR" is what you want then the answer is yes.

It is not true VBR because it will never get below minrate or above 
maxrate even if it would be possible/necessary for maintaining the 
encoding quality
