I created a MOGRT in After Effects 25.0 (on Windows 10) with intro/outro animations in protected regions. Works fine with only visual layers.
But whenever I try to add a sound effect to the MOGRT inside a protected region, the template cannot be extended beyond the initial duration of the After Effects composition. Suddenly the clip of the MOGRT displays a little triangle in Premiere Pro 25.0, as if it was a fixed-length video clip. However, it normally behaves as a MOGRT (options can be changed in the Properties panel).
I attach a screenshot showing two versions of the same MOGRT, one exported with the sound effect muted and perfectly resizeable, and the other exported with the sound effect on and limited to the 5 sec length of the AE composition.
Could Adobe devs please try to fix this ? It's been years since I try to make use of MOGRT with responsive design with sound effects, and it's always been plagued with bugs. This complicates my workflow significantly.
I am available to provide further information if needed.
Thanks
