How can I use a green screen to add a video onto a moving plane? So, I've been working on my project for a little bit now.
I'll be holding some boards, and flip through them whilst superimposing videos on them.
I've grasped Plane Tracking, and how to project (superimpose) a video onto it!
But now I hear that using a green screen (as the plane) will be much easier later on, especially when it comes to masking out obstructions (such as fingers holding the screen).
I can manage that. I can get a nice green (or whatever other color) panel and hold it up to the camera.
So, I've gone up to the &quot;Tracking&quot; and &quot;Creating a Plane Track&quot; stage; I've finished those.
But, I can't find many tutorials telling me what to do afterwards!
I did find one, (https://www.youtube.com/watch?v=bGSKjFz4NVg), but it's an older version of Blender and some parts are a bit confusing.
Could someone point me to a tutorial that's updated, so I can simply follow along to achieve this simple effect?
I apologize again for the questions; The deadline is tight on this project and I only need to know how to do about 2 effects, nothing more.. I can do the rest in After Effects, which I actually know how to handle. Please help me!
No need to use afterFX for this.
The idea is quite simple.
You use green, or some color that is not present in the scene, to create a matte (or mask) that can be used to combine other elements in the scene.
In the compositor connect the image that has the green element add a keying node, select the key color and the node will output Image and Matte separately.
Use the Matte to control the mix between the tracked plane and the image.

Or use just use the mask and feed the original image. This setup will avoid correlated alpha issues.
