  • Premiere Pro CC 24-bit Audio in Timeline

    For anyone who can assist:

    Is there any way to get 24-bit audio in a sequence or project setting?

    We recently made the jump over from FCP 7 to Premiere Pro CC and we are hoping this is an ‘audio works differently in Premiere’ issue.

    We have been editing ProRes (422HQ) as that is how our broadcast clients require final delivery. However, they also request 24-bit audio. That’s how our audio designers have delivered our final mixes for years.

    We see no option to create a 24-bit project or 24-bit sequence in Premiere Pro CC.

    We see there is only an option on export…also if we use the Match Sequence setting during export, Premiere reveals to us the audio is 16-bit (even though 24-bit audio is in the timeline). Yes, if it’s unchecked we can create a custom 24-bit preset.

    HOWEVER, is Premiere currently converting our 24-bit audio to 16-bit in our sequence, thus forcing us to convert a lower quality audio (16-bit) back to 24-bit for the exported master? This seems like it would be detrimental to the quality of our audio delivery. How can we use the original 24-bit audio file from our designer?

    Can we adjust the audio settings in Premiere Pro CC project or sequences to reflect a 24-bit audio.

    Thanks!

    That didn’t answer the question. It was a helpful link to understand more about the audio in Premiere, thank you.

    However, if the only audio I was using in my timeline had uncompressed 24-bit properties, why does the Premiere option for exporting with Match Sequence Settings say it’s 16-bit? In fact, I don’t have a single piece of 16-bit audio media anywhere in the project. And if ‘settings’ was mentioned, why does an option for the bit-depth not exist…only the Sample Rate & Display format?

    I really hope I’m missing the obvious, and I appreciate any thoughts.

    Just uncheck “match sequence settings” select ProRes and the appropriate output. Premiere does its audio calculations natively in 32 bit float so you can export 24 bit audio masters.
