Audio bitrate and bit depth

[Victor Gonzalez Motos]

Hi everyone!

First of all, thank you very much for your time. I have a problem with audio bitrate and bit depth in DaVince Resolve 17 Beta and I am looking for some help or advice.

The original source is a video in mov. format and 1080p/60FPS that I have edited in DaVince Resolve. The audio of the video is stereo and has a bitrate of 255 Kbps and a bit depth of 32. However, when I export the audio only using the source format (mov.) or mp4 for further editing in Audacity, the exported audio has a bitrate of 196 Kbps and a bit depth of 16. Does anybody knows how can I keep the source properties of the audio when I export it?

I have been playing around with the different options, formats and codecs in the delivery section, and even when I set up a 255 Kbps bitrate, the software continues to export in 196 Kbps. The only way to export in higher bitrate is exporting in mono instead of stereo.

Does anybody knows why I cannot set up a higher bitrate? Am I missing something?

Thank you very much for your help,

V

You are talking about AAC encoded audio. Resolve does have limited output options for AAC. However you should be exporting PCM 24 bit if you want to do further work in Audacity. Re-encoding to AAC is lossy. Audio files are small and there is no reason not to use uncompressed (PCM).

Also Fairlight in Resolve is a vastly better featured audio editor/ mixer than Audacity.
