How to fix a Premiere Pro export stuck on Content Credentials

Updated 7 stepsFor Adobe Premiere Pro

The short answer

If your export stops at Validating ingredients and the sequence has AI-generated media in it, you've hit a known Premiere bug that Adobe has no fix for yet. Adobe lists it for Premiere 26.5 and 27.0 on Mac and Windows, still under review on November 10, 2026: the export never starts encoding and shows no error. It happens when the AI-generated media's Content Credentials list a very large number of ingredients. Turning off Content Credentials doesn't help, because Premiere always applies them to exports that contain AI-generated media, and exporting through Media Encoder stalls the same way. Watch Adobe's known issues page for the fix and update when it ships.

7 steps

In Premiere Pro

  1. 01Check that it's the known issue
  2. 02Don't count on the Content Credentials switch
  3. 03Don't switch to Media Encoder for this one
  4. 04Revert AI frames you don't need
  5. 05Know what Render and Replace does and doesn't do
  6. 06Run Adobe's general export checks
  7. 07Go back a version as a last resort

  1. 01

    Check that it's the known issue

    Adobe's entry matches three things: the export or Media Encoder job stops at Validating ingredients, no error appears, and the sequence contains AI-generated media, such as Generative Extend clips or Firefly videos you sent with Open in Premiere desktop. It lists Premiere 26.5 and 27.0. Adobe's help has no separate entry for a stall called Preparing Content Credentials.

  2. 02

    Don't count on the Content Credentials switch

    In Export mode (File > Export > Media, Cmd+M or Ctrl+M), the Content Credentials section sits below the output preview, with Apply Content Credentials preferences at export, and the General section has Export Content Credentials. You can turn these off for ordinary exports. Adobe says doing so in Preferences or on the Export screen doesn't prevent this stall, because exports with AI-generated media always carry Content Credentials.

  3. 03

    Don't switch to Media Encoder for this one

    Adobe's entry covers exports from Premiere and from Media Encoder, so queueing the sequence won't get round it. Media Encoder's known issues page also says that for a Premiere project it uses the Content Credential information already in the project file.

  4. 04

    Revert AI frames you don't need

    For a Generative Extend clip, right-click the AI-generated label on the clip and choose Revert to Original to go back to the original media. Adobe ties the stall to AI-generated media in the sequence, but it doesn't say that removing that media lets the export finish, so treat this as a test, not a documented fix.

  5. 05

    Know what Render and Replace does and doesn't do

    Clip > Render and Replace flattens a selected clip into a new MXF OP1a or QuickTime file, and Restore Unrendered brings the original back. Adobe tells you to use it on each Generative Extend clip before Project Manager, XML, AAF, EDL, OMF or OTIO exports, Audition or After Effects. It doesn't list it as a workaround for the Validating ingredients stall, and its Render and Replace page says nothing about Content Credentials.

  6. 06

    Run Adobe's general export checks

    For a hang during export, Adobe suggests exporting to a different format, switching a custom preset to a built-in one, turning off Enable hardware accelerated decoding in Preferences > Media for H.264 or HEVC, and temporarily removing third-party transitions or plug-ins. If only one project fails, import its .prproj into a new project with File > Import and export again. Adobe doesn't tie any of these to this bug.

  7. 07

    Go back a version as a last resort

    When the cause stays unclear, Adobe suggests an earlier version: in the Creative Cloud desktop app, open Apps, click More actions on Premiere, choose Other versions and install one. Adobe lists only 26.5 and 27.0 as affected and doesn't say which earlier version avoids the bug.

Good to know

Before you start

Note 1
Content Credentials are metadata about who made a file and how, including whether it was generated by AI. Premiere adds the creator details you set on Adobe's Content Authenticity site, and Media Encoder applies the same settings automatically.
Note 2
Large files are scanned in the background: Adobe's Media Encoder known issues page (25.2) says Premiere scans imported files for Content Credentials, a very large file may not finish before you export, and you should wait until the status shows correctly in the Project panel if you need the credentials in the file. A 25.2 bug where that scan congested networks during import is fixed in 25.2.
Note 3
Another Content Credentials entry, listed for 25.2 and still under review: videos imported from Sora and then extended with Generative Extend don't show their Content Credentials correctly. Adobe gives no workaround.
Note 4
Checked against Premiere 27.0 and Adobe's known and fixed issues page as updated on November 10, 2026.

Do it in Eddie

If the edit is in Eddie, its MP4 renders in the cloud, not in Premiere or Media Encoder.

Ask Eddie to export an MP4 and it renders the edit in the cloud, in 1080p or 4K, up to 60 minutes long, and gives you a download link. The desktop app renders on your own computer from your local source footage, with no length limit. This only helps for an edit you build in Eddie: it doesn't render a sequence that exists only in Premiere.

FAQ

Questions

Why is my Premiere export stuck at Validating ingredients?
Adobe lists it as a known issue in Premiere 26.5 and 27.0: the export hangs when the sequence contains AI-generated media whose Content Credentials list a very large number of ingredients. Encoding never starts and no error appears.
Can I turn off Content Credentials in Premiere Pro?
For ordinary exports, yes: the setting is in Export mode, in the Content Credentials section below the preview and as Export Content Credentials under General. Adobe says exports that contain AI-generated media always carry Content Credentials, so turning it off doesn't stop this stall.
Is there a fix for the Validating ingredients hang?
Not yet. On November 10, 2026, Adobe's known issues page listed it as under review with no workaround and said to check back for updates.
Will exporting through Media Encoder get round it?
No. Adobe's entry says exports from Premiere and from Media Encoder can both stop at Validating ingredients.
Does Render and Replace fix it?
Adobe doesn't say so. It documents Render and Replace for flattening clips, and recommends it on Generative Extend clips before Project Manager, exchange-format exports, Audition and After Effects, but not for this export stall.
