Hmmm ... strange IDEA for sure. But a well-designed AeMoGRT with less compute-intensive components at play can be played back in realtime in PPro.
This feature will be useful for previewing AeMoGRTs in the Source Monitor; allowing the user to better engage with the AeMoGRT prior to committing them to the Timeline.
I appreciate not all AeMoGRTs will be suitable but the idea to first preview an asset before commiting it to the Timeline is Editing 101. So ... nothing strange here. - just allowing a user the ability to audition/engage with an AeMoGRT will allow them to make better decisions.
