Premiere projects saved in v25.6.0 cannot be opened in other v25.x versions

We are aware that customers who saved projects in Premiere v25.6.0 may find that those files now open only in v26 (beta) and cannot be opened in v25 versions. We know this is disruptive, and we’re working on a fix. 

 

What you need to know: 

  • Projects saved in v25.6.0 save in the v26 version format. 
  • Because of this, they can’t be opened in earlier versions, including v25.6.1 (even though it is the current generally available release) 
  • We’re developing a tool that will let you convert affected projects back to a v25-compatible file.  

 

Our Solution 

We’re building a small app that will convert a v25.6.0-saved project back to the v25 format. We’ll share more information, including availability and instructions, as soon as the tool is ready in the coming days.  

 

We know that there is nothing more important than the reliability of a project file, so we’re working with urgency to get this downgrade tool in your hands as quickly as possible. 

 

We know there are a number of downgrading apps available online, but we strongly recommend utilizing our tool when it becomes available. Non-Adobe apps and scripts are often outdated and may cause crashes and data loss.  

 

Further Details 

A bug caused Premiere v25.6.0 to prompt customers to enable Object Masking even though it is not yet in full release. Object Masking (and our yearly major version update) changes the Premiere project file structure such that it can only be opened in v26, which is only available in public beta. Turning this on caused projects to save in the newer v26 project format, even though users were still technically on the v25 release line. 

 

Opening an older project in v25.6.0 triggered a prompt to save a copy of the project with “_1” appended. We know that many customers upgraded the project and continued working in the new copy, potentially also deleting the original. This means the only active version became the file saved in v26 format. 

 

Premiere 25.6.0 was only available briefly before being replaced by 25.6.1 and is no longer available to reinstall. This means impacted users who auto updated to 25.6.1 cannot open v26 formatted projects.

Are seeing a prompt to enable the new masking feature when you launch?

ProRes 4444 exports are always entirely black for sequences sent from Premeire 25.6. This was not a problem in 25.5. 

 

Tried downgrading Media Encoder to 25.5 but the problem persists and seems to be caused by Premiere.

 

Swtiching the export setting to ProRes 422 or other codecs seems to work fine. Happens with any sequence anmd any source media I've tried. 

Anyone else seeing this?

Hi @crabspanner -   Thanks for submitting your bug report. We need a few more details to try to help with the issue.

 

If you make a new project and import one piece of media in 25.5 do you still have the same issue?

 

Can you try and hold down "SHIFT" while launching Premiere and check the boxes
"Reset app preferences" (Backup Preferences first)
"Clear media cache files"
"Reset plugin loading cache"


Sorry for the frustration.

Just updated to 25.6 and now when I start PP, it shows me a dialog box titled, "Try the new AI-powered object masking." On that dialog box is a button "Enable new masking." If I click that, PP crashes and restarts, showing me that dialog all over again. If I click "skip," I can use PP as normal, it seems.

 

OS is macOS 15.7.1 on an M1 Max MPB.

 

I tried clearing my media cache and restarting but that didn't help.

Hi @tonywithasony - 

We are sorry for the troubles you are encountering. We understand where our oversight lies and apologize to the users encountering this frustrating scenario. Rest assured that we are preparing a patch for 25.6 and will release it as soon as possible.In the meantime, we recommend uninstalling 25.6 and reverting to the stable 25.5 release.
 
In the Creative Cloud Desktop app, click the Apps tab in the sidebar.
Locate the Premiere Pro box, then click the three dots in the lower left corner of the panel.
Select Other versions, and from the list, choose Premiere Pro (25.5).
If you’ve enabled the masking feature in 25.6, you’ll also need to clear out some preference data before reinstalling:Remove the 25.0 Preferences Folder
  • Windows: C:\Users\<YourUserName>\AppData\Roaming\<AppName>\Preferences\25.0
  • macOS: ~/Library/Preferences/<AppName>/25.0
 
You can safely delete the entire 25.0 folder.  
Please note that deleting the preference folder will reset all your preferences. 
 
We will update you as soon as the fix becomes available

I just upgraded my released version from 25.5 to 25.6 ... and now on launch, Premiere says my 25.5 Production projects "were created in a previous version  and  must  be updated" ... ?

 

What the hay?

 

@Kevin-Monahan or someone ... ?

When I try to send clips from Premiere Pro to After Effects using “Replace with After Effects Composition”, After Effects opens but doesn’t import the selected footage — I just get an empty composition. The dynamic link between the two apps still works, but the clips themselves never appears in After Effects.

Hi,
Today I created a new project in Adobe Premiere. I cut a film about 2 hours long, turned off AP, came back, turned AP back on, and unfortunately, I can't open the project because it says the project was created in a newer version, but I have the latest one...

 

The second problem is that when I select a section of the film in AP and click "Replace with After Effect Composition," it opens AE and creates a new composition. The composition time is correct, but the audio and video are missing.

 

How can I fix this? I'm currently unable to work in AP or AE, and I won't be editing the film from scratch in the older version because I've invested a lot of time.

Where can I find what is new, or if the bugs I experience have been solved?

I don´t think it has been updated yet. The link below stops at version 25.5.

 

What’s new in Adobe Premiere Pro

I have a project that was "saved in a newer version of Premiere Pro and cannot be opened in this version."

I have the latest version, believe me.

This was tried on another computer with the latest version of Premiere (23.6.0 from August).

With the exception of the project creator having a time machine, how can this happen?

Try creating a new project and import the old one into it.

I just tried that, and when I tried to import the project, it gave me the same message.

 

(Also, thank you for your reply.)
