Premiere Pro - Warp Stabilizer + Transition --> fails

Try applying Warp to the clip, then nesting the clip, THEN add the transitions.

Warp is the single heaviest effect used, even more so than Neat video noise reducer. I normally apply Warp, then do a render and replace operation to new media for the clip.

Then the processing is all done, and other effects work without bogging the computer down. And exports take a lot less time.
