Premiere export video -audio bitrate problem

As per apple app store launching requirement, video audio bitrate is requested to be 256 kbps,

so I need the file having the exact specification.

However, Premiere export the file with the audio bitrate a bit lower than the one in setting, i.e.setting 256 kbps and outcomes 247 kbps.

I have tried so many settings within the requirement but neither one gives me a correct exported file.

The source file is 3xx kbps which exceed the rate I need. So I'm really confused and hope to know the solution....

Honestly, I'd try submitting it with the approximate requested bit rate... bwdik.

Just doubt if app store launch my video successfully with a approx. bitrate,

it's a task for work & another department help with the launching & judge me with the specification

...so let's see

Your problem here is that anything using a variable bitrate can only ever provide an approximate bitrate to the app store. You need fixed bitrates with audio - this is yet another reason why lossy audio is bad for your general wellbeing & state of mind.

What you need to do is extract the audio from these Hero devices and turn it into something nice & sensible - PCM. This will give a fixed bitrate, and you will find a lot of audio problems, glitches & upsets will melt away like the spring snow on a sunny morning. You will also have less stress in your life.

The best place to start is with the devices themselves - tell them to use PCM WAVE files, not MP3, AAC-LC or any other lossy garbage. Honestly.

Are you using a VBR or a CBR encoding please?

Also how are you ascertaining the audio bitrate is 247kbps instead of 256kbps?

Is the source file lossy or lossless?

Are you on a Mac or a PC?

The more information you can give the better chance we have of actually solving your problems.

Thanks for the detail,

I'm not sure about the encoding, where can I do the setting & which one is better?

For the audio bitrate I check it in file information by Mac "Music" App,

and the source file got higher bitrate than I need so I think it should be ok for the export?
