Bug: Responsive design doesn't work if there's audio
Audio seems to break responsive design.
Today I tried making a graphic template for Premiere. I set an intro and outro protected regions like normal. I also included a sound effect in the intro protected region for this one.
Premiere ignored the responsive design for the mogrt and just trimmed it like a normal clip if I tried to change the out time (I also could not extend it beyond the original run time).
I tried a few things to fix it but the only thing that worked was removing the sound effect. So audio seems to break responsive design.
My sound effect was a standard WAV file. It played fine in both AE and Premiere so there wasn't an issue with reading the file.
The sound effect was only present inside a protected region so it shouldn't have needed to be stretched at all to play.
Thank you for submitting this idea.
This is a known limitation with Responsive Design – Time in motion graphics templates created in After Effects. MOGRTS with audio can not be time-stretched. It is documented here:
