How to Write AI VFX Prompts for Fire and Explosions

Fire and explosion prompts are among the most common requests in FXbuddy. Getting them right means specifying three things: where the fire is in frame, what it erupts from, and how big you need it. This guide shows you exactly what to include.

Generic prompts like "add fire" produce generic results. The AI video engine works best when you give it a spatial anchor (where in the frame), a physical cause (what's burning or exploding), and a mood or intensity (raging inferno vs. small campfire). The difference between a forgettable overlay and a shot that looks planned from the start is usually a single sentence of scene context.

Fire and explosion VFX in FXbuddy are fully AI-generated and match your scene's ambient lighting, so a fire added to a night exterior will cast warm light onto nearby surfaces. You don't need to manually key or composite anything.

What FXbuddy needs in a fire or explosion prompt

5 example prompts you can copy

add a large vehicle explosion in the mid-ground centre frame. shockwave ripples forward. thick black smoke column rising. debris scattered left and right. camera shakes on impact.
place a controlled building fire in the background, upper left. orange and red flames licking broken windows. heavy smoke obscuring the roofline. no foreground debris.
add a ground-level fireball erupting from the centre of a dirt road. brief bright flash, then rolling orange fire and white smoke. camera lens flare on the ignition frame.
small campfire in the foreground, bottom centre. low warm flames, crackling embers drifting upward. soft orange light spills onto the ground and the lower edge of the frame.
add a close-range explosion from a pipe bomb at ground level, right side of frame. sharp concussive flash, dust and gravel kicked forward toward camera. no large fireball — keep it practical scale.

Tips for better fire and explosion results

Frequently asked questions

How do I make an explosion look grounded in my scene?
Tell the AI the surface the explosion erupts from, the camera distance, and whether you want debris. For example: "mid-distance car explosion, concrete surface, shockwave shakes camera, debris scattered left." The more scene context you give, the more the effect integrates with your footage.
What is the difference between a fireball and an explosion prompt?
A fireball prompt focuses on the rising ball of flame and smoke without specifying an impact source. An explosion prompt implies an originating impact point, shockwave, and debris. Use "fireball" when you want atmospheric fire; use "explosion" when you need a physical event with spatial context.
Can I add fire to an existing clip rather than replacing it?
Yes. FXbuddy generates fire and explosion VFX that composite onto your clip. The AI engine matches your scene's lighting so the effect looks integrated. Describe where in frame the fire should appear and the AI positions it accordingly.
How many credits does a fire or explosion generation use?
A 5-second generation uses 10 credits. A 10-second generation uses 20 credits. Starter plans include 100 credits per month; Pro plans include 750 credits per month.
Do fire prompts work for smaller practical fire like candles or torches?
Yes, though results vary with scale. Practical-scale fire works well when you specify the size explicitly — for example: "add a single flickering torch mounted on the left wall, warm orange glow, no smoke." Large-scale explosions and fireballs tend to produce the most consistent results.
