Very new to blender video editing, I have found an animated style I want to replicate (gif below) and include in a video but I don't know what it's called and thus cannot look for a tutorial without knowing the jargon around it. It's the character shadow animation bit in the gif.
Could someone please point me in the right direction or give me a name of what this might be called? Assume I have no prior knowledge of animating or creating mattes in blender, where do I start if I want to animate a frame of video like the example and put it back in the target video? Cheers in advance
