multi-layer (more than 2) green screen implementations in imovie

>all necessary assets saved as or converted to a video file (mp4, mov., etc.)

>ideally plain background (can play around with textures etc. to see what works but will be more tedious that way)

>can be any file type

*works best on still background but i'm not your boss

lay down plain background as bottom track

first green screen asset on top of background →

use green/blue screen feature and adjust accordingly →

export and repeat for all assets until they're all ready to assemble

to assemble, lay down plain background again and use picture-in-picture to put down first asset →

export and repeat, layering each asset upon the previous assembly→

export when done!
