AfterCodecs

1.12.2 - 12 August 2026

• Support for After Effects, Premiere and Media Encoder 2027 / v27.0 BETA released recently in Adobe Creative Cloud
• macOS After Effects : opening AEfx .aep project from Finder was sometimes producing the annoying popup "The document X.aep could not be opened. After Effects cannot open files in the After Effects Project format" instead of opening your project file, until AEfx was restarted, now solved in this version. Others plugins loaded by Adobe could also impact this behavior. This might solve discussion on those forums : https://community.adobe.com/questions-529/after-effects-cannot-open-files-in-the-after-effects-project-format-39556 https://community.adobe.com/t5/after-effects/quot-after-effects-cannot-open-files-in-the-after-effects-project-format-quot/m-p/11836476 https://community.adobe.com/t5/after-effects-discussions/problems-with-opening-a-aep-file-for-after-effects-2022-on-mac/td-p/12999714 https://creativecow.net/forums/thread/after-effects-cannot-open-files-in-the-after-effects-project-format/
• Popup was sometimes waiting a long time before it could be closed, now fixed
• Trial message : improved .txt message written when you are encoding in Trial mode with better explanation as to which license you need to activate to unlock AfterCodecs. This message is also shown as a popup in After Effects, in Premiere Pro console and in Media Encoder logs
