Mogtr Problem :( what is this???

there is a way to chat with adobe help and they sometimes use some kind of tricky 'remote access' with you, and they look at your computer specs and program information and sometimes that solves problems for users of this product.  You might consider trying that ( adobe help, chat, etc. ). Plan on being there at your computer for some time ...

That image might be useful to engineers, but to get that to them you would need to post it over on their UserVoice system, as that's their site for bugs/ideas communication with the developers. We're mostly peer users here, so a screen like that means no more to me than you.

You didn't actually answer even one of my questions, btw ... and without those answers, neither I nor anyone else can really do any troubleshooting with you.

No way whatever to give any suggestions as you didn't give any information, at least enough other than simply guessing.

So ... OS/CPU/RAM/GPU ... and the version of Premiere you're running ... and yes, those are important to establish the computer is capable of properly handling a complex graphic file like many mogrts.

Next ... are those the included ones, or have you built or acquired them somewhere?
