Quick answer
Upload a head-to-toe photo in everyday clothes to an image-to-video tool, paste the prompt below and replace the costume line with yours. The prompt keeps you in plain clothes until a snap and spin, hides the change in sparks, then names every piece of the costume. Halloween Costume Video does the witch version with no prompt.
A costume reveal is a before, a trigger and an after, and AI tools get it wrong when any of the three is vague. This prompt is built so you only change one sentence: the costume. It’s for general video tools and isn’t the template’s own prompt.
The base prompt
Vertical 9:16 video, 10 seconds. A living-room Halloween party: orange string lights, paper bats on the walls, carved jack-o’-lanterns on a table, friends in homemade costumes chatting in the background. The person in the photo, still in their everyday clothes, waves at the camera, snaps their fingers and spins twice inside a burst of orange sparks and light smoke. They step out of the smoke wearing [COSTUME], strike a pose and laugh while the friends cheer. Keep the face exactly as in the photo. No text.
Replace [COSTUME] with the costume, piece by piece. “A witch costume” gets you whatever the tool imagines; “a tall pointed black hat, a long black dress, a flowing cape and black boots” gets you that.
Costumes to drop in
Vampire
Collar and color, no fangs on the face.
a high-collared black cape lined in red, a red waistcoat and a white shirt with a ruffled front
Old person
The comedy reveal: props, not wrinkles.
a beige cardigan, a grey wig in a neat set, round glasses on a chain, and a walking cane
Ghost squad
Everyone changes at once.
a white sheet ghost costume with two eye holes, and on the snap every guest spins and comes out as a matching sheet ghost
The “old people” costume, done kindly
The old-person reveal is a popular one, and it works best as a costume, not an aging filter. Ask for clothes and props (cardigan, wig, glasses, cane, a shuffle in the pose) and leave the face alone. Prompts that ask for wrinkles or aging tend to replace the face, and the joke stops being you.
Why each line is there
- “Still in their everyday clothes”: without it, many tools put the costume on from the first frame and there’s no reveal.
- “Snaps their fingers and spins twice”: a visible trigger tells the tool when to switch.
- “A burst of orange sparks and light smoke”: covers the change, the way a flash hides a cut in a real edit.
- “The friends cheer”: a reaction turns it into a party moment rather than an effect.
The witch version without prompting
Halloween Costume Video runs the witch reveal with party sound already in, from one everyday photo. 100 credits, back if the run fails.

Common problems
The costume is there from the start
Put “still in their everyday clothes” in the first sentence about the person, and mention the costume only after the spin.
My face changed along with the outfit
Pick costumes without masks or face paint, and keep “keep the face exactly as in the photo” as the last instruction.
Only I changed in the ghost-squad version
Say “every guest” and “at the same moment”, and expect more tries: group changes are harder for general tools.
FAQ
Can AI put me in any Halloween costume?
Generally yes, if you describe the pieces. Branded characters are hit-and-miss and sometimes refused, so describe the look instead of naming it.
How do I make the old people Halloween costume video with AI?
Use the base prompt with an old-person costume: cardigan, grey wig, glasses on a chain, a cane. Ask for clothes and props rather than aging the face.
Can a whole group change costume at once?
In a general tool, yes, with “every guest spins and comes out as…”. The Reelfie template changes one person, with the party around them.
Is this the prompt behind Reelfie’s template?
No. The template runs its own setup. This one is for other generators.
