P: Changing frame rate of a video clip only changes the duration of the first audio track

We have the same issue, Premiere Pro 25.5 and also tested in 25.6 beta. Windows 11 23H2 OS Build 22631.5472. Nvidia driver 573.42. We are seeing this across multiple users, systems and projects. 

Hi Dani, do you know if this has been addressed?

Thanks,

Dan

Same bug happening here with a 16 track Prores, only A1 gets Interpretted, the rest are ignored by Premiere. 25.4.0

Hi @Peter DPP,  
Our engineers always appreciate a screen recording of the issue, so if you are able to provide one, that would be awesome. Can you also provide more details on your system specs? Thanks. I hope we can help you soon.

Hi Rach

Thanks for your reply. I have seen this with both MXF files (OP1a) and Quicktime ProRes. These are full length feature films or trailers and they are multichannel audio (usually 8 discrete mono tracks), and yes, the modify -> Audio channels does acknowledge all audio channels.

I might be able to do a small screen capture showing the issue if that helps? Let me know.

Hi @Peter DPP, 

Thanks for submitting your bug report. We need a few more details to try to help with the issue. What type of footage are you working with?  Are these clips coming in with multichannel audio, or are you syncing/ linking them in Premiere?  When you go to the Modify Menu and look at the Audio Channels, does that acknowledge all the audio channels in the clip?  Please see: How do I report a Problem?  Sorry for the frustration, and thanks for reaching out.

Version 25.3 - when you modify (interpret footage) from 24 fps to 23.976 on a 110 min. feature your audio track decreases by 6 seconds and 14 frames. So my master is 24 fps I modify to 23.976. I make a new sequence from clip and the clip in the timelines shows the audio out by the above amount.  Sync is affected in playback.  This happens if I make a new sequece myself or generate one by right clicking and adding new sequence from clip.

In version 25.0 and 25.1 - if I follow the same step as above the audio track is actually extended by 1 frame which is not an issue and has always been the norm. No sync issues.

In order to complete this project I have to go back to these versions to work.  I'm not exatly sure at which version the error starts but I just noticed it in version 25.3.  Is anyone else having this problem?
