AAC codecs : No 320 and 256 kbit/s ?

[NXYZ]

Hello everyone !

About AAC codecs.

Why are not proposed 320 and 256 kbit/s ?
Is there a setting or trick, to restore these bitrates ?

Thanks in advance.

Why are not proposed 320 and 256 kbit/s ?

Probably some copy and paste from older to newer AAC audio encoder plugins in action here. Higher bitrates with AAC make sense only with 6 (up to suppoted max value of eight) channels. I don't think this is relevant in any way to "fill the gaps" in the bitrate menus, but less than 64 kbit/s per channel may be undesirable regarding quality.

Is there a setting or trick, to restore these bitrates ?

Create a project script for your encode (prior to exporting = saving the output, use "File" --> "Project Script" --> "Save As Project..." to generate the .py file), modify the value matching the bitrate in the script to your liking, run the script via "File" --> "Projekt Script" --> "Run Project...", do not open audio codec configuration dialog, save / export the video.

(1) Find on the official site : Up to 256 kbit/s per channel. So it is relevant.

(2) It works !

Thanks for the solution.
