Replacing green screen with motion

Hello dudes! What's up?
I'm trying to discover a way to replace green screen in premade videos with some kind of movement.
The video I'm trying to do this can be found here: https://www.youtube.com/watch?v=XzHdKv9UDCk
Is there a way to do this easily? I tried to use motion tracker in the green square but it isn't helping at all.
It seems it wasn't designed for it.

Hi,
Not quite sure of your end aim - can you be more specific about what you are wanting to achieve, as in replace the green with what?

I think you're wanting to fit your video content into the frame of the green shape, right? That's not what the typical use of "green screen" is, so it's a little confusing.

In any case you won't be able to use the MT tool at all. Instead you'll need to add a mask to cop the edges to fit, then use keyframes in the PiP Designer or Keyframe tool to manually make all the motion and rotational changes to keep the your content "inside" the moving green shape.

It will take some time and some practice to get it right, but it isn't too hard to do

Thanks for answering me! I'm trying to replace the green screen area with an image or a video (the image or video needs to follow the green screen area.
By the way, is it possible to replace easily green screen areas with a lot of movement, like a man holding and moving a cellphone
or a notebook, changing the camera, perspective, etc?
I found out there are plugins in After Effects that allow make this kind of edition.

Thanks for answering me! And if I wanted to replace the green screen area in a footage with a lot of movement, changing perspective, etc.? Is there a tool that allows to do this easily?

There's a good example bellow. The camera is moving changing the perspective:

Unfortunately there is no tool for automatically doing anything like that. As I wrote above. you'll need to manually set keyframes & masks to accomplish what you want.

You can let the developers know that you'd like to have an automated tool by going to File | Rate Us & Provide Suggestions
