The Setting: I am a motion designer that has made a Mogrt template in After Effects for an Editor to use on long form content in Premiere. in AE, I animated an Intro and Outro for the template and created protected regions around the keyframes and the beginning and end of the comp. At first it was working as intended: when the Editor uses the template in Pr, he can lengthen and shorten the template as necessary without effecting the intro and outro animations.

The Problem: The Editor has found over time, when revisiting the project file, or even letting it sit open overnight and coming back to it in the morning, that the timing of the template has changed. The intro and outro animations change where they appear (randomly it seems). The duration of the template clip appears the same, but the timing within is off. It happens about 20-30% with the templates on his timeline.

Attempted fixes that failed: Clearing the memory cache, closing and restarting the program, restarting the computer, opening the file on another PC with an earlier version of Pr (13.1.2), dragging the template from Essential graphics panel onto the broken template on the timeline

Our Current Workaround: The Editor has recently discovered that if he nests the templates, they do not experience the problems templates on the main timelines have. We don't know for sure if this trend will hold, but it's been working for a few days now.

This problem happens randomly to some template clips, and to different degrees, so it is a huge problem for my Editor when he has to drag new templates to the timeline and re-enter new information every time this happens. And on long form content, it is incredibly time-consuming to keep checking on all the templates before rendering each time.

I've attached a ZIP that contains 2 samples of this problem occurring (labeled Bad), along with how they are supposed to look (labeled Correct) and images of the timeline for each clip. One is much more drastic than the other, but the problem occurs in both. The Editor has some text he created in Pr that dissolves in, which is supposed to happen after the intro transition. You can use it to see how off the timing of the Mogrt has become.

As a motion design template I use an after effects composition with responsive design segments - intro and outro. When I reload the project in Premiere Pro,the outro animation disappears and my motion graphic ends with a regular cut. This problem exists since the beginning of Motion Graphic template's functionality.

Also, this problem appears when I cut a template's clip into two pieces - each piece doesn't have a new outro/intro, but it starts/ends with a regular cut. Once I loose an intro/outro segment, there is no way to get it back, other than dropping a new template on a timeline and changing all of the properties again.

I have mogrts in FHD 25fps in AE and the sequence in Prpro is also FHD 25fps. Hmm.
Ok, so what happens is that when I apply them in the sequence they always seem fine. The ins and outs works like a charm. But, (and here's the kicker) when I change the duration of the mograph, sometimes the in OR out (it's different) aren't respected and the mograph "cuts off without the animation. And sometimes, when I change the duration of tha mograph by draging it, the animation starts or stops somewhere towards the middle of the mograph (not at start/end). AND, sometimes it looks perfect, but when reopening the project the animation is cut off again. But other instances of the samne mograph works just fine. This has happend also before, on a Mac, so I think I am doing something wrong here... :-(

The Reset Duration saved our team from the ongoing timing issue.
However, when I stretch the mogrt in the sequence, the protective region gets stretched a little bit. It's more noticeable when I stretch it more than 1000%. It's a problem when I need to add more than one template with different durations.
For now, the only way to fix it is by Reset Duration.
The fact that I have to hit Reset Duration over and over when the timing gets changed is annoying, and also our team is not allowed to update Premiere Pro to CC 2020 yet which has the Reset Duration feature.
