I know this is years later, but I’ve found this extension useful for doing this if anyone hasn’t found something by now. You can use it to convert the keyframe values of a tracked mask into transform values. I’ve ended up creating those “camera shake” adjustment layers by tracking a mask over a handheld video in Premiere and applying those as transform values to an adjustment layer. Still have yet to find like a pack of these or something tho
