  • Data Transformations must be performed using AutomationWorkflow

  • AW must be used to republish relevant assets when metadata, used in embed, changes, these metafields is not part of the reuse logic as that would severely general transcode performance.

  • ExifTool is slow so use of this feature will impact transcode speeds.
