Known issues in Adobe Media Encoder

This document provides information on the list of known issues in the Adobe Media Encoder.

December 2021 Release (Version 22.1.1)

If Premiere Pro or Media Encoder is experiencing out-of-memory errors on M1-based Macs, adjusting the amount of memory allocated to Adobe applications may help decrease or eliminate the occurrence of these errors. You can try increasing the amount of memory that the operating system uses to achieve a 50% balance between Adobe and other applications/OS.

To work around this issue:

In the memory allocation area in the Memory preferences dialog (Preferences > Memory), it shows the amount of RAM available to Adobe and other applications.

  1. Change the value listed for other applications to represent 50% of the total installed RAM.
  2. Restart Adobe application to activate new memory allocation.
