How it works

  1. 1. Choose fire VFX
    Start with sparks, embers, flames, heat bursts, film burns, or explosive overlays.
  2. 2. Apply in the Finisher
    Open the effect in SizzleFinisher and place it over your footage.
  3. 3. Blend and time it
    Use intensity, opacity, screen-style blending, and timing so the fire feels intentional.
  4. 4. Export the final shot
    Download an MP4 for action edits, trailers, gaming videos, ads, or social posts.

Why creators use this workflow

  • Adds instant energy to action, horror, music, and sports edits
  • Works as downloadable assets or browser-applied effects
  • Good for thumbnails, intros, title cards, trailers, and dramatic transitions
  • Pairs well with cinematic grades, shake, glow, and glitch presets

Pro tip: Keep fire overlays motivated by the scene. Sparks near impact points or edges usually feel more believable than full-screen flame.
