I have figured out how to add a picture in picture (smaller video playing within a larger main video. However, both videos are dark, and I would like to add a thin, light-colored border around the smaller video in order to create a contrast between that smaller embedded video and the main larger video. I've successfully added a border to the clip, but it doesn't seem to translate to that border being part of the PiP.
As an alternative, I thought about adding a separate empty rectangle around the PiP or a full rectangle behind the PiP in order to "fudge" a border, but I'm not sure how to do that either.
Can anyone help?
