Does FXbuddy fire VFX look like a real practical fire?

Runway Gen-4 and Kling 2.5 Turbo Pro produce fire and explosion effects that integrate with the scene's existing lighting, which gives them a more grounded look than stock overlays. The quality depends heavily on clip complexity and prompt specificity. Mid-ground and background fire elements tend to look most convincing.

Can FXbuddy add explosions to a clip without destroying the original footage?

FXbuddy generates a new version of the clip with the explosion or fire integrated. The original clip on your timeline is not modified — the generated effect lands as a new layer.

What is the best use case for AI fire VFX compared to traditional stock overlays?

AI-generated fire integrates with the scene lighting and perspective, which stock overlays often don't. If you have a specific shot where the fire needs to feel grounded in that exact environment, FXbuddy's approach is often more convincing. For generic wide-shot fire over black that you're just screen-blending, a good stock pack may still be faster.

Which model does FXbuddy use for fire and explosion effects?

FXbuddy uses Runway Gen-4 Turbo as the default for fire and explosion effects. Kling 2.5 Turbo Pro is available as an alternative for longer clips or when a different motion style is needed.

AI Fire and Explosion VFX in Premiere Pro

Add fire, smoke, and explosions to any clip from inside your timeline. FXbuddy generates pyrotechnic effects that integrate with your scene's lighting and perspective — no stock overlay, no separate compositing session.

Getting fire into a shot without practical pyrotechnics has historically meant either stock footage overlays (which rarely match the scene's light) or expensive CGI. AI-generated fire sits in between: the model sees your actual footage, understands the scene's environment, and generates fire or explosion effects that are grounded in that specific frame. It's not perfect, but for mid-ground elements and establishing shots, it's often more convincing than a blended stock layer.

To be clear about limitations: AI fire generation works best for mid-ground to background elements. Close-up fire interacting with a foreground subject (flames touching an actor's face, for example) is beyond what the current models reliably handle without visible artifacts. Use this for environmental fire, background explosions, and establishing-shot pyrotechnics.

How it works in FXbuddy

Select a clip from your Premiere Pro or After Effects timeline. Think about where in frame you want the fire to appear and how it should interact with the scene.
Describe the pyrotechnic effect in FXbuddy. Include size, position, type (campfire, structure fire, mid-air explosion), and how it should move through the frame.
FXbuddy sends the clip to Runway Gen-4 Turbo (or Kling 2.5 Turbo Pro for longer clips), which generates the fire or explosion integrated into the footage. The result returns to your timeline in 60–120 seconds.

Example prompts for fire and explosion effects

Add a large explosion in the background right of frame at the 1-second mark. Fireball with rolling black smoke. Long lens compression look.

Add a contained campfire in the foreground left. Warm flickering orange light. Smoke drifting upward in the still air.

Make the building in the background look like it is on fire. Flames in the upper windows. Black smoke pouring from the roof.

Add a car explosion in the middle distance at the start of the clip. Fast initial fireball, then rolling black smoke.

Add a small ground-level explosion at the right edge of frame. Debris and dust. Realistic scale for a military thriller.

When to use AI fire and explosion VFX

Action and thriller content: Add background explosions or building fires to establish stakes and genre without a pyrotechnics budget.
Documentary recreations: Fire in background plates for historical or documentary-style reconstruction footage.
Music videos: Dramatic fire elements for high-energy or conceptual visual moments.
Social and short-form content: Explosive transitions or dramatic reveals in creator content where practical fire isn't feasible.
Game trailer and promotional content: Fast iteration on cinematic fire effects without a VFX pipeline.
