So I have an image I want in frame in the corner of my video. When I resize it and use the pip effect it will resize the part how I want, but below it there is a strip that is part of the original image I started working with, and happens by itself and messes up what I'm doing. It does it with video in the pip windows also. I have had this happen on a few videos now, and it has made me ditch what I was trying to do all together and do a different idea. Now i keep getting held up when I need t use this feature in my videos. I have an attached screenshot.

On a side note I have been working with that same part of the video shown I am using the cookie cutter effect, and when it pops up I want the opacity to fade of the main video while the cookie cutter segment pops up. When I go to insert envelope it only displays freeze frame, and not anything else. Not sure what I am doing wrong but somebody can shed light on that also that would be helpful. Thanks!
