Creating MOGRTs: "sticky" keyframes?

[jampff]

I'm trying to create a mogrt (1st time). It's just simple text with a few formatting controls and "in" and "out" animations. I know I've seen the info I'm looking for somewhere but I can't find it. I'm trying to educate myself on it but I don't know the right terms to search for.

I'm happy with everything in my mogrt, EXCEPT: when I bring it into Premiere, I can't change the time duration of it to make it longer. Shorter, yes of course, by simply trimming the mogrt clip in the timeline back. HOWEVER, this just gets rid of the "out" animation I have at the end of the mogrt.

How can I create a text mogrt with "in" and "out" animations that can be extended or shortened to whatever time duration I like in the Pr timeline, AND automatically moves the "out" animation to the end of the graphic, no matter how long or short it is? Currently the comp in Ae that I'm creating the mogrt in is 6 seconds long.

I'm sure there are multiple tutorials out there for this already. I've seen a few before, I believe. I will be grateful for just a link to the education I need if you don't have time for a detailed explanation. I just can't remember what the correct search terms for this are; every search I've tried turns up nothing.

Thanks!

(Also, side quest: is it possible to add SFX to a mogrt? Or is that just wishful thinking at this point...)

Sounds like you are describing Responsive Design - Time, which allows you to locked down parts of a precomp and then when you extend the layer, those parts remain while the rest extends.

I made a video a while back explaining them:

They should export as any regular mogrt and allow you to alter them in PP.

Regarding your side quest, as far as I know pretty much any effect can be exported.  Obviously exceptions for things like tracking, rotobrush, but there should be no reason you can't add others.
