My goal was to create a custumable morgt file from After Effects for Premiere Pro with just the setting that the user need to change not more options. And this should automaticly change to the correct aspect ratio for a rezise in 4:5 1:1 and 9:16. The Aspect ratio is based on a HD 1920x1080 16:9 Timeline.
So In AE I createtd for example a Titel in HD, made a null Object with three checkbox effect, 4:5, 1:1 and 9:16, if one of this is checkt then it resize the Titel to the correct aspect ration.
The point of this ist, that the operator do not need to retype all title and lower thirds but only need to tick the right aspect ration in the grafic settings.
