Crop then center and zoom My video is 1080p HD, shot with GoPro. Using GoPro Studio I have removed the fisheye effect and exported it in AVI format.

Using Pinnacle 17 (or another tool, but this one has to be free), I want to crop some part of the entire image, then zoom it (a little), then center it above another clip. 

I don't know how to do this. I've tried effects in "media editor" but so far I only ended with standalone pictures.
I used Picture in Picture to display my orginal video, cropped, zoomed and where I want above another picture or video.
