I have a job that will export an XML file of videos from MAC FCP

But I have found that even though the audio depth of my video is 24Bit, the depth will become 16 after transferring out through Premiere

What should I do to make Premiere output XML with the same audio depth as video audio?

The audio bit depth is usually set in the 'Export Media' dialogue, under the 'Audio' tab. It defaults to 16-bit, and if you are using 24-bit or anything in floating point (Adobe's idea of floating point can be strange too - in Audition it can be eitjher 16-bit fixed with a 16-bit mantissa or 24-bit fixed with an 8-bit mantissa) and you are outputting to fixed point you should be using dither - assuming that there are no more tweaks to be done to the audio, of course.

Hi Chris

 

thank you for reply

I need some clarification, are you talking about adjustments when outputting the video?
Because I can't find an option to adjust the audio depth in the output XML.

 

thanks again~~

If there are still things that need to be done to the audio then you should output in floating point again.

Hi Neil

 

Thanks for the detailed explanation
I refer to your introduction to operate, the options I modified allow me to get 24bit output video
But when I export XML, the audio depth still shows 16Bit
Premiere Pro's FCP XML confuses me...
