After Effects 2025 PNGIO library error PCS illuminant is not D50

Question

With a project set up as "Adobe color managed" with a working Color Space of "Rec.709 Gamma 2.4" trying to export as a png sequence returns the error "... PNGIO library error: profile 'After Effects ICC Profile': 0h: PCS illuminant is not D50 (5027 :: 12)". This does not occur in After Effects 2024 with exactly the same settings. To reproduce the error set up a project with the settings as in the screenshots and attempt to export a png sequence. Windows 11.

I have found the fix to the problem. Seems like it was corrupt preferences. I reset my preferences to the defaults through the preferences dialog and now I am able to export to .png without any errors.

Thanks for sharing the screenshots, Darryn.

I tried the same settings and exported successfully. Does this happen with a specific project? Is there any media imported into the project that you're trying to export? Are you able to export a different format?

Let us know. Moving this thread from Bugs to Discussions for troubleshooting.

Thanks,
Nishu
