You know Captain Disillusion? "The World's Greatest Blenderer"? Well, he does this effect all the time in his videos; Adding videos on top of a board he's holding, to make it seem like he's holding one large, suspiciously bezel-less, screen.

SUSPICIOUS BEZELS INDEED!!

Now, I'd like to emulate that in my video project. This MUST be a simple process, easier than adding a 3D object to a scene, since it's simply tracking a 2D plane and superimposing a 2D layer on top. But I just can't figure out HOW I would look this up! "Chroma keying" just turns up tutorials of how to remove backgrounds from videos (Done that before), and other keywords didn't help.

So, how can I do this? And, do I need a green board for this, or would a white board with dots on it be better? And importantly, how would I go about masking the video (to compensate for fingers, etc)? Would it be better to use Adobe After Effects, since I have that in hand?

Thank you guys for the help! It would be amazing to be able to make this effect work.

What you want is called Plane Tracking. The idea is that you associate 4 trackers to the vertices of a plane or an image.

Track the elements and select Create Plane Track. enter image description here

In the compositor you use the tracking information to deform an image.

For more detail read the following links:

Can't choose Plane Track in Plane Track Deform node while compositing

Is it possible to take a mask clip and 'connect' it to a specific point on a moving object?

And yes, it would be easier to use a green (or blue) screen on the card you film, otherwise you will need to create masks over the fingers and other elements that occlude the card. Such process is called rotoscoping, it is more complicated and tedious than dealing with green screen.

    I was JUST trying out masking.. It is a real big pain. Could you please tell me more about using green screens to add plane trackers? I have no idea how to start off, and every tutorial I see just uses trackers and masks.. I would REALLY appreciate it if you can tell me, that would make the process so much easier! Thank you for the help! – BeardWix Jun 18 '20 at 12:30
