  • Mogrt Responsive Design – Time functions clarifications

    Posted by Cricket Collins on September 25, 2025 at 7:17 pm

    Hi all,

    I’m in the process of building out a mogrt in After Effects and am testing it in Premiere. I have a protected region, then some static frames, then an unprotected animation, more static frames, and a protected outro. I would ideally have a mogrt where the in/out are protected but the animation in the middle is rate-stretchable, which doesn’t seem like a hugely complicated thing but I’m running into issues.

    The protected regions are functioning as expected, but when I try to rate-stretch the middle animation, it behaves… not how I would expect it to. And the Adobe Help page on Responsive Design – Time only discusses mogrts that are static except for the in/out. What I was hoping would happen is that I could add cuts on either side of the middle animation, the first and last frames of that segment would be “anchored” in a way, and I could stretch the clip as needed in between those anchor frames. Instead, if the clip is trimmed to be longer on the right end, it does slow down the animation, but then the first frame is different. To be more specific:

    I’m animating on text, which will need to be timed out to speaking speeds. The first frame before rate-stretching has no text; after rate-stretching “Lorem ips” is visible. It seems to both rate-stretch and slip the clip. Is there a way this can be avoided? Is the RDT function just too new and unpolished to use it for anything other than lengthening static graphics? Am I missing something obvious?

    Responsive Design Time in MoGRTs produces iffy/maybe/meh results, at times. This is my experience. Then, it’s designed for stretching only the head and tail of a MoGRT but what you’re trying to achieve is beyond the feature’s design.

    An option is to deliver the MoGRT as part of a PPro Project file with a sequence set up with two copies of the MoGRT at the head and tail which the user can time stretch. For the middle section, you will have to look at using a Dynamic Linked AEP. It can get tricky but this is a bullet-proof option.

    Thanks for the response, Roland. I was worried that was the case… my unit has been using Dynamic Linking, so I was investigating mogrts as a way to possibly speed up that workflow/avoid opening After Effects… maybe one day!
