Audition not able to open Premiere Project

[Dominic Witherow]

I have a long (1hr 40mins) project in Premiere Pro that I am trying to edit in Audition, as normal. However, about 50% of the way through the Audition 'opening project' dialogue, I get the following error:

/Volumes/****.prproj

Error: File not supported by any currently registered plug-ins.

That is the entirety of information given by the error message and then Audition opens, but with no data imported from Premiere. I have been using this workflow ever since Adobe launched Mercury Transmit and have never seen anything like this before.

My system is fully updated, with the latest Adobe and Apple software versions:

Premiere 25.4.1 (build 3)

Audition 25.3.0.71

MBP M4 Max, 128GB, 4TB SSD

OSX 15.6.1

Next step will be uninstalling and re-installing Audition, but any other ideas will be very well received!

I have fixed the immediate issue, but there clearly remains a bug in the software.

Having discovered a couple of similar errors mentioned by others, I suspected the issue could be caused by the nested sequences in my timeline (another user had the same issue that was caused by multi-cam clips, hence my suspicion). I rendered out the video and put it into a duplicated timeline with the audio from the nested clips rendered out too. Now, the 'clean' timeline transitioned to Audition with no issues at all.

Conclusion - there is a problem with nested and multi-cam clips going through dynamic link into Audition and there are reports of it from at least 5 years ago.

UPDATE! I think I was wrong as to the primary cause of my issue, but have determined what it was. Whilst the issue DID lie within the nested clips, the specific nested clips that caused the issue were all using ProresRAW exclusively and even more likely to be the cause, they all used Neat Video v6. No other clips on the timeline were ProresRAW but I am now convinced the real issue was the denoising software.

On an adjacent note - why does Premiere not offer a native denoiser, especially as RAW is key to professional workflows now?
