I want to recreate this smoke/cloud effect which is used in the Arrival (2016) movie end credits.
I uploaded a sped up version of the credits to see the smoke dynamics.

I know how shaders work and can comfortably implement simple GLSL fragment shaders, but looking at this I can't seem to find a way to get started.
Starting points I considered:
- Using a noise function: Every noise function I could find looks unnatural and unsmooth. Not what I need.
- Creating 2D/3D particle simulation: This seems a bit overkill and even then I need functions that do not look calculated.
- Just use some sprites and transform them randomly around: That's lame and still looks 'fake'.
If you could guide me to a starting point on how to accomplish a somewhat similar looking GLSL shader implementation that would be great!
