The core part of this tool is to have at least a rough roto of your moving subject and for that I used Runwayml, it's an amazing platform to create such garbage mask, after that we go through the following steps:
- Trace that roto sequence inside of Houdini.
- Move that trace to camera space so it matches %100 the back plate "crucial for compositing".
- emit particles with some turbulence, you can color them by age.
- Rasterize them.
- Shade & Render.
Note:
- Renderer is Redshift.
- File is indie license.
