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 Non-Adobe apps and scripts are often outdated and may cause crashes and data loss.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.

Their typical staggered rollout takes up to three days. So by tomorrow, probably everyone will have this.

When will this be available everywhere? By remove 25.6 and not enabling 25.6.1 everywhere, it seems a lot of us are up the creek without a paddle since we uninstalled 25.6 to fix the previous issue expecting an immediate ability to update to 25.6.1

Hi,

Thanks for the post. It's still being rolled out, I believe. Thanks for your patience.

 

Cheers,

OK, I saw another post that you did get 25.6.1, I still haven't down here in LA.

Same thing was happening with the Auto Save backups.

It's a 'staggered sequential' release as they're doing now, by zones around the planet. You might not get it for a few more hours.

Anyone else not seeing the update for 25.6.1 though? I've restarted Creative Cloud multiple times

See Kevin's comment above a couple posts for how to get around this. The 25.6.0 had some code that somehow thought it was actually 26.x I think.

Hello,

I've recently saved several projects using 25.6, but after updating to 25.6.1, I'm getting the message below. Reverting back to 25.5 doesn't allow me to open these files because they give me the same message below. Why am I not able to open 25.6 saved projects with 25.6.1? Will there be a fix for that or am I SOL on that?
