When I want to modify them by checking the Fade in and Fade out in the PIP Designer window, and then preview the movie, the PiP track takes forever before the transparency goes to full resolution. For a 2 minute clip, it took 40 seconds before the fade in went away.
Seems like it should only take a few seconds, or better yet, you should be able to pick the amount of time it takes, like you can with transitions.
Am I missing something or any ideas?
