This is from my other channel. Just some ideas on placing another video on top of a background video, and zooming in and zooming out. Like if you want to paste a video insert unto a window..it will be like 'oh anyone can do that'.. then you zoom in and the inserts in the video will also adjust in sync with the background video.. One crude way is to zoom out to max and save the entire video as a new video then edit it again ad zoom in/out of the new video. But then the video insert will be of very low quality.
This tutorial is on how to keep the video insert quality high as you zoom in and out of the entire scene.
Editing software used is Magix Movie Edit Plus Pro 13.
You can visit their site: http://www.magix.com
I downloaded a trial version of the software long time ago and I ended up
using them. Much faster and less bloated as compared to other editing
software.
