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

    I don't think recording as a .wav file is gonna make a perceptable difference but testing is the way to find out, but converting to wav or aiff with a standard sampling rate of 48k before editing is always a good idea.   And not sure about hitting a precise bitrate on your output, but for posting on youtube/vimeo/instagram/facebook the export presets in premiere/ame are all aac and I've never had any issues.. In fact, I don't think you can actually output an h264 with uncompressed audio...  I recently cut a music video and the audio engineer insisted that I output the final piece for posting on youtube as uncompressed and I had to output as prores to be able to have uncompressed audio.  Don't think I could change the audio to uncompressed with an h264 video compression (unless I'm having a senior moment and misremembering.


    yup, just looked.  you cannot encode an h264 file with uncompressed audio at least in AME...   The OP didn't say what format he was encoding to and even if he's posting as a quicktime file, almost all websites will eventually enocde as h264.   Not sure about the apple app store.  Maybe the OP can post the requirements...

    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?
