Recently we experimented on how to generate a realistic fog effect with AI models.

VFX Generation Prompt for Fog Effect

A good VFX generation prompt should consist of the following

  1. Subject
  2. Subject Movement
  3. Camera Movement
  4. Environment
  5. Lighting/Aesthetic

But what is a good fog effect VFX generation prompt?

Feature Prompt following ability (⭐ worst, ⭐⭐⭐⭐ best) Examples
density ⭐⭐⭐⭐ sparse, thin, exceptionally sparse, semi-transparent, varying densities
texture ⭐⭐⭐⭐ wispy, delicate tendrils, gossamer-thin, swirling, billowing, dry ice fog, mist, cloud
movement direction ⭐⭐⭐ left to right, right to left, upward, outward from background to foreground, inward from foreground to background, diagonal, toward the upper left of the frame
movement speed ⭐ slow-motion, unhurriedly, steady, gentle
source ⭐⭐⭐⭐ from lower portion of frame, from center point, from bottom, from background, from the lower right corner
movement style ⭐⭐⭐ twisting and curling, bubbling, rolling waves, drifting, dispersing, flowing, swirling

Fog effect videos and their prompts

You will notice there are colored texts in the prompt, Red means generation will follow this section nicely. Yellow means it might or might not follow the prompt section. Green means it doesn’t have any impact on the final generation.

AI Fog Effect Video Prompt: A thin stream of white smoke is gently blown into a dark space, moving in a smooth, slow-motion flow. The smoke twists and curls as it expands, forming delicate, swirling patterns. The soft wisps gradually disperse into the air, creating an ethereal, dreamlike effect against the pitch-black background. The lighting subtly highlights the intricate details of the vapor, emphasizing its graceful movement.

AI Fog Effect Video Prompt: A black background with a sparse, semi-transparent fog blowing toward the camera from the lower portion of the screen. The fog is light, drifting gently, and appears to dissipate slightly as it moves forward. Its movements are slow and ethereal, with the fog's density fluctuating as it progresses, creating a soft and mysterious atmosphere.
