Lots of AI teams were experimenting on best article title generator using GPT2, no one would ever dare to try agentic workflow at that time. Now with AI video it seems we are at the same time of GPT2, you want a car but AI Video can only give you faster horse. Almost everyone is working on gimmicks and bells and whistles instead of pushing another video version of scaling law.
If we must stay in GPT2 video for quite sometime, then let’s find out if we could at least make some use of the current AI video model. Recently we spent sometime and experiment 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
- Subject
- Subject Movement
- Camera Movement
- Environment
- 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.
Ground Emission Atmosphere Towards Cam 1
× Features not working: move toward the viewer / camera / screen √ Features working nicely: density/texture
- 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.
- 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.
- Prompt: In a pure black void, delicate wisps of smoke drift gracefully toward the viewer. The smoke is exceptionally sparse and ethereal, floating with a dreamy slowness that creates an almost hypnotic effect. Each tendril of smoke is remarkably thin and translucent, barely visible against the darkness, yet distinct enough to create depth. The smoke emerges from the lower portion of the frame, steadily advancing forward with subtle, gentle turbulence. As it moves, it maintains its wispy nature, never becoming too dense or overwhelming. The static camera captures this ethereal dance as the smoke particles spread out while approaching, creating an intimate connection with the viewer. The smoke's pure white color contrasts beautifully against the pitch-black background, with its movement remaining consistently gentle and measured throughout.
