Will the whole photo turn dark?

The light cools to deep blue dusk, but the person stays lit and readable. The fireflies add their own warm glow around them.

Can I use a photo taken indoors?

You can, but fireflies look most natural outdoors. For indoor photos, a window or plant in the background helps the scene feel plausible.

Can I use a different model, or make it longer?

Yes. Five seconds on MiniMax H3 is the default; before you generate you can set up to 15 seconds or 2K on H3, or switch to another model listed for this effect in Studio, such as Wan 3.0 for up to 30 seconds. The Generate button shows the updated price first. Our samples were made on MiniMax H3, so other models may interpret the prompt a little differently.

Will it change what's in my photo?

No. The effect only adds motion, light and atmosphere; everyone in the photo stays exactly as they appear in it. The default model doesn't filter photos. Some models you can switch to in Studio apply their own content filters and may turn a photo down.

Is my result private?

Yes. Your upload and the finished clip stay private to your account and never appear on a public page.

Each effect defaults to a five-second clip priced in US dollars on the Generate button. Before you run it, you can switch to a different model, adjust the length, or change the resolution in Studio, and the price on the Generate button updates to match. An ordinary failed or expired run normally releases the reserved amount. For a content refusal, follow the selected model’s billing policy.

Will this effect change how the person in my photo looks?

Your photo anchors the subject; the effect adds the motion and look described in its prompt. Check the face, hands and clothing in the result. If a gesture distorts them, try a clearer crop or a simpler movement.

Can I upload a photo of someone else?

Only one you have the right to use, and never to make intimate content of a real person without their documented consent. The content policy has the full rule.

What this effect sends

This is the full prompt, word for word. Copy it, or open it in the generator and change anything you like.

Within the first second the light cools to deep blue dusk and fireflies start rising out of the ground all around the person. By the third second there are hundreds of them, warm yellow-green points of light swirling up past the face and shoulders, several drifting right past the lens as big glowing blurs. The final frames hold on a blue night scene packed with glowing fireflies, the person standing in the middle of them and smiling into the lens. The person stays exactly as they appear in the photo.

Customize in the generator

Pictures that work best

Pick a photo with grass or foliage around the feet so the fireflies appear to rise from something.
Daylight photos work well. The shot cools to blue dusk, so a bright start makes the change more visible.
Keep the face unobstructed. The final frames hold on a smile into the lens, with lights close to the face.
If you want fewer lights, lower the number in the prompt. Large counts make a dense, glowing finish.

How it works

01
Add one photo
Choose the photo to match the example: include both people for a shared gesture, and keep the face and any hands involved clearly visible. Upload your own photo or start with a Fireflies at Dusk sample.
02
Check the price
Fireflies at Dusk defaults to a 5-second clip for $0.185. Swap the model or change the length and resolution before you run — the price on the button updates to match, and that's the whole cost of the clip.
03
Generate
Your Fireflies at Dusk clip renders in the background, lands in History and is never published.

What it does to your photo

Within the first second the light cools to deep blue dusk and fireflies start rising out of the ground all around the person. By the third second there are hundreds of them, warm yellow-green points of light swirling up past the face and shoulders, with a few drifting right past the lens as big glowing blurs. The final frames hold on a blue night scene packed with glowing fireflies, the person standing in the middle and smiling into the lens. The person stays exactly as they appear in your photo throughout.

In our test runs on MiniMax H3, a white-haired, white-bearded man in a royal blue linen suit and white shirt standing in tall grass by a lake watched the light cool to deep blue dusk by second one and a half, fireflies rise from the grass at second two, and hundreds of them swirl past him and drift by the lens as big glowing blurs by the end while he smiled.

Outdoor photos with grass, fields, a garden or a lakeshore look most natural, since fireflies rise from the ground. Mid-length portraits give the lights room to swirl around the body. Indoor shots and busy city backdrops work, but the effect feels less grounded. Very dark photos leave the blue dusk little room to read as a change. The effect leaves the person exactly as they are in your photo and only adds the motion, light and atmosphere.

It runs on MiniMax H3 for five seconds by default, and H3 itself goes up to 15 seconds and 2K if you want more. Studio also lets you move the same prompt to another model before you generate, such as Seedance 2.0 or Wan 3.0, and the price on the Generate button updates with every change. Our samples were all made on MiniMax H3, so other models will read the prompt in their own way.

Suits summer-evening posts, fantasy and storybook portraits, and calm atmosphere clips.

Open the prompt in the generator and change "warm yellow-green points of light" to "soft white points of light" for a quieter, starlight look, or change "hundreds of them" to "a few dozen" for a sparser scene.
