[HELP] how to encode variable bitrate AAC audio?

[Selur]

yes, i set audio passthrough, but hybrid hints error, can't support EAC3 in cut.

Okay, I give up on that since you really don't want help other wise you at least would have shared the error message.

audio that only can be set one of bitrate or QF, and there are no variable bitrate options, in bitrate, only can be set a number, no variable bitrate.

Atm. you are using ffmpeg aac encoder which only offers vbr through setting a target quality factor.
Qaac would allow to encode to vbr using cvbr (=constained variable bitrate) with a bit rate or by setting a target quality factor.
FHG (which you don't have) and FDK would allow to encode to vbr (mode) by setting a target bitrate.
FAAC and Nero AAC like ffmpeg offer vbr through setting a target quality factor.
