In photoshop I use the "color range" Selection menu to do very detailed (but automatic selections)
I can easily select dozens of foreground > middle > background alpha channeled images
separate the layers a bit and you have an interesting pseudo 3D "Model" built of layers.
But it is a still image & I want to do this with Video
I am wondering it there is a way to do such a "color selection " for every frame uniquely
so that I can divide my video into many "layers" of foreground middle & back automatically
without having to "animate a mask" with motion tracking.
(or maybe there is a better automatic way to do it with masking)
I actually think it might be More difficult in After Effects
