Warp Stabilizer

Hey, 

Sometimes when I'm using the Warp Stabilizer effect on Premiere Pro, the last frame of the used video becomes black for some reason. It happens randomly, and I've never found a proper solution expect deleting the last frame which is super inconvienet to do sometimes. I've tried to nest the specific video and applying the effect to the nested video, sometimes it helps, but in general it just turns everything to be much messier and deorganized that way. I hope Adobe sees this and fix this bug in the future updates. 

Thanks, 

Nadav
