I spend far too much time nesting clips in Premiere for warp stabilizer.
It probably should be possible to drop warp stabilizer onto any clip in the timeline, if no speed or different dimensions to the timeline then it works as normal.
If it does have speed or different size then Premiere auto nests, deals with the warp stabilizer and then adjusts speed or scale in the working timeline.
Seems like an easy fix that would save me a bunch of time.
