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…
