Person to Particle effect
on Mar 26, 2017 at 7:02:16 am

Hey fellow Motion Graphic enthusiasts!
I have a project that I am working on that requires me to turn footage of a person into particles. These particles will loosely form to the subjects body and will trace the motion of this person as they perform. The performance would be a dance and the final product would be just particles that resemble human form and movement against a drab (most likely black) background. I am posting because I have a couple different ideas on how to do this and I wanted to hear the opinions of other pros!

My first attempt would be a layer with an alpha channel applied to it that isolates the subject and then linking that to a Particular emitter layer with the emitter layer (I have been able to do this with text layers but not successfully with keyed footage. )

My other solution would be to dress the subject in a target suit and key multiple particular layers to follow those targets to create a more abstract particle dance. ( A problem that arises with this is that the null tracers will not be able to follow a 3d tracksuit)

Anyway, I thought this would be a fun animators challenge and I would love to hear what people have to think and any suggestions are more than welcomed!

Hi,

When you say you haven't been successful with keyed footage, have you tried pre-comping the footage. Particular can't see the alpha channel when the key is applied in the same comp. Pre-comping should take care of this for you.

Hi Graham,
Yup the pre-comp did it! It initially was not working even with the referenced layer pre-comped because of the order in which I applied Particular. But after stepping backwards and re-attempting it worked like a charm. Thanks for the input!
