How to Fix After Effects AEGP Plugin Error 5027 12

If you have ever tried to export your composition from After Effects to Media Encoder, you may have encountered the error “After Effects AEGP Plugin Error 5027 12”. This error means that there is a communication problem between the two applications and that Media Encoder is not installed or recognized by After Effects. This can prevent you from rendering your composition in the format and quality that you want. In this article, I will explain some possible causes and solutions for this error and how to avoid it in the future.

Cause and Solution: Firewall or Antivirus Software

One possible cause of this error is that your firewall or antivirus software is blocking the connection between After Effects and Media Encoder. This can happen if your software considers the dynamic link between the two applications as a potential threat or malware. The dynamic link is the feature that allows you to send your composition from After Effects to Media Encoder without rendering it first. It saves you time and disk space, but it also requires a stable and secure connection between the two applications.

To fix this problem, you can try turning off your firewall or antivirus software temporarily and see if the error goes away. To do this, you need to find the icon of your software on the taskbar (usually at the bottom right corner of your screen) and right-click on it. Then, select the option to disable or turn off the software for a certain period of time (for example, 15 minutes or until you restart your computer). After that, try to export your composition again and see if it works.

If it does, you may need to add an exception for After Effects and Media Encoder in your firewall or antivirus settings. This will allow the software to recognize the dynamic link as a safe and trusted connection and not block it. To do this, you need to open your software and go to the settings or preferences menu. Then, look for the option to add or manage exceptions or exclusions. You may need to browse your computer and select the executable files of After Effects and Media Encoder (usually located in C:\Program Files\Adobe\Adobe After Effects [version]\Support Files\AfterFX.exe and C:\Program Files\Adobe\Adobe Media Encoder [version]\Adobe Media Encoder.exe). Alternatively, you can copy and paste the file paths into the exception list. After that, save the changes and restart your software.

If you don’t want to turn off or modify your firewall or antivirus software, you can also export your composition directly from After Effects using the Render Queue instead of Media Encoder. The Render Queue is the built-in feature of After Effects that allows you to render your composition in various formats and codecs. To use it, you need to go to Composition > Add to Render Queue in the menu bar of After Effects. Then, you will see a new panel at the bottom of your screen with your composition name and settings. You can click on the Output Module and Output To options to change the format, quality, and location of your rendered file. After that, you can click on the Render button to start the rendering process. This method may take longer and use more disk space than the dynamic link, but it will bypass the communication problem with Media Encoder.
