Export 32 bit float AAF

[tc6363]

i'm working with many hours of 32-bit float audio recorded on tentacle track-e's. after pic lock i'd like to be able to send our post house an aaf so they can bring the audio into pro tools in 32 bit-float. but premiere doesn't seem to be able to do this-- only 16 and 24 bit options.

any suggestions for workflow or any planned updates for premiere to be able to export 32 bit float aaf's? i can bounce out an xml to resolve and then resolve can do it. but that's a hassle. hoping this is already implemented in pp or in the works for an upcoming update and i don't know it.

AAF does support 32bit float but Premiere can't export it at the moment.
workaround... export an XML, pull that into Resolve, export AAF from there.

thanks fir the confirmation. i already stated that workaround in my post. dealing with a complex feature length edit, i'm hoping to hear from someone at adobe to find out if they are planning to implement 32-bit float aaf export support.

according to @Kevin-Monahan the Adobe team is aware of this issue and is working on a solution. no timeline at the moment, but sounds like it's coming.

Does anyone here know if the Resolve workaraound actually works? I'm in the same boat here, trying to get my 32bit Float files from Premiere into Pro Tools. 

When I go through Resolve the best I can seem to get is 32bit integer... No option that I can see to output in float. What am I missing?

I actually came here for the opposite of your issue. I couldn't get a film out from Resolve as a 32bit float AAF, so I was hoping Premiere could handle it. I've tried every export option in DaVinci Resolve and it always clips first in an AAF before doing anything else (levels/normalization).

I'm here for the exact same issue. Have you or anyone found a solution/workaround yet? I'm getting audible and visible clipping when importing into pro tools via AAF.

Turns out there’s no way to make a 32bit float AAF.

The only workaround seems to be to normalize all your peaks to 0db before
you make the AAF and export 24bit as always. I did this for a feature a few
months back and it worked like a charm.

Like p-arrow said, I had to normalize everything, which was a massive pain. I duplicated all my production audio to archive, brought everything into Adobe Audition and normalized to 0 or maybe -.1 dB, then the clips relinked and I could make a normal AAF in both Premiere and Resolve. The sucky part is that destroys all premixing you've done and your offline will be completely thrown off by different amounts. Luckily my film was actually locked, so I didn't have to go back in to raws at any point.
