Create a night celebration with one visible firework burst

1. Task and boundary

Create one night-celebration accent from a bright core already present in the source image, ending after its radial light pattern fades.

The movement expands outward from one starting center. It is not a travelling light leaving a trail or several new fireworks appearing across the sky.

Begin in the sky; omit a ground launch, people handling fireworks and text effects.

2. Authorized first frame

Provide an authorized night image with one clear bright core above a recognizable skyline. Leave dark space around the core for expansion and keep the horizon and foreground visible.

3. Use the generator

Open the image-to-video generator, select your authorized first frame and paste the prompt. Review the available controls before submitting; this page does not upload or generate for you.

1. Choose a core with enough surrounding dark sky to contain the whole designed burst.
2. Request one expansion and fade rather than a repeating celebration loop.
3. Pause at the starting center, widest pattern and dimmed finish to compare the skyline.

4. Prompt and timing

Fixed night view of the original skyline and one existing bright core. From that same center, a limited set of luminous streaks expands outward into a single radial burst. Let the streaks grow, slow and dim until the bright pattern mostly fades against the same dark sky. Keep the skyline and foreground still. End after this one burst. Do not add new centers, fireworks text, a sky replacement, camera shake or another explosion.

5. Inspect the output

Review the complete result, then pause at the listed events. Mark an obscured event not visible; the prompt itself is not evidence that it happened.

• The bright pattern grows from the original visible core.
• The expanding streaks belong to one burst rather than new independent centers.
• The light pattern visibly dims instead of freezing at maximum brightness.
• The original skyline and foreground retain their positions throughout.

6. Fix one failure

• If multiple bursts appear, retain one center and remove any request for a fireworks show.
• If the whole sky flashes or changes, reduce the burst size and keep the original horizon as a fixed reference.

7. Ending and limits

The one original burst has mostly faded, leaving the same night skyline readable.

This designed light effect is not a verified event recording or evidence about a real firework’s size, timing or behavior.

If a save or download control is available, retain the complete clip alongside the first frame and the exact prompt.
