Hi, this is my first post. I am sorry if it is posted in the wrong spot. I have dancer footage and a few sample videos of sand and I'd like to almost mimic what MK12 has done in the Quantum of Solace intro. The link below shows exactly what I would like to happen. Skip to 2:22min:

I have tried using track mattes but of course the sand will stay within the silhouette of the dancer and I am stumped on how to have the sand continue off of the dancer. I have thought of tracking the dancers movement much like how 3D tracking is done in boujou but...its not quite the same...bit confused.

Thank you very much for any help.

This was most likely done using a 3d app and some complex particle systems. If anything, Particular or Form my get close. The silhouette of the dancer comes from a real dancer shot on chroma and there may be some motion capture involved as well..

if you have trapcode's particular, you can try using a layer (the dancer silhouette) as an emitter, then create a sand-like particle system (lots of rather small particles, maybe some wind and a turbulence field).

i've seen a few text-to-sand tutorials using particular that would probably help you get started...

if you don't have particular, then you might check out some of the other text-to-sand tutorials. good ol' particle playground may be able to get similar results (and there are some text-to-sand tuts that use particle playground), but you'll also need to try and incorporate a fractal noise gradient to use with the ephemeral property to get that ripply particle cloud look.

Thanks guys for the quick advice.

I'm actually working with trapcode form and particular in this project as well. The dancer footage I have is also footage of my own that I have keyed out. So I feel I am soo close. I definitely have run into many tutorials making sand to text or vice versa. I do have the equipment (green screen, and a canon hf21 camera) that can help in capturing actual sand. I was thinking real sand would be much better than particles even if it is trapcode particular.

If I use trapcode particular, you're right, wouldn't the particles have to be VERY small? I'd like to keep the silhouette a silhouette and not have the particles define the shape...

Ah, i see. Particular just might do the job. I'll try experimenting with real sand as well.

Okay, I've messed around with trapcode particular and its looking much better than I thought it was capable of. However, I am still going to use real sand keyed out from a green screen. Once I have the footage of sand, how do I "link" the footage to the footage of the dancer. Much like how trapcode particular emits particles from the dancer, I'd like to do the same with the sand footage. Any leads?
