I’m trying to make a fire VFX for a recorded movie, but I’m having trouble with setting the speed I want.

Here is my render with Time Stretching set to 400. The fire is burning too fast:

And now here is a video with the Time Stretching set to maximum (900). It’s slower, but also the frames got choppy:

I’m new to fire simulations and I can’t seem to find the right settings for this. My scene is a city and I need to apply big fire on buildings, and because of it the fire should burn really slowly. How can I achieve this?

Embergen has some nice freebies that work with Blender. You can import them as VDB sequences and render away.
