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

[Aditya Dandavate]

Okay, thank you sir.

Should I keep the bufsize 5 times that of maxrate ? Will that help in
effective allocation of bitrates ? Also, for getting the best possible
quality in this case, how high should be the value of bufsize ? What is
your recommendation ?

 (I use the slow preset for both x264 and x265 for getting better quality
at same filesizes btw).
