Change Outfit in Video with AI: New Clothes, Same Shots and Cuts

You can change the outfit in a video with AI and keep every shot, cut and pose. Here is how with Riffkit's Swap mode, from a real test: three outfits in one 12-second clip, the exact brief, the cost and what drifted. A disclosure first: we make Riffkit.

Click for the silent side-by-side: the original on the left, the Swap on the right. Seedance 2.5, 720p, 12 seconds, 2,340 credits, about 6 minutes to render.

How an AI outfit change works

Swap renders the whole video again on the source's own clock. The shots, cuts, camera moves, poses and timing stay where the original has them, and the clothes you name change. That is why the new clothes look worn. It is also why small details can drift, so check the result before you post.

Higgsfield's Video to Video page lists an AI Outfit Swap that changes the color, cut and fabric of the clothes in your clip, using Kling 3.0 Omni Edit or FLUX 3 Video Edit. It says the person keeps their poses and pacing while the new clothes blend with the light and shadows. In Riffkit Swap, you write the outfit change as a brief, for clips up to 45 seconds.

The test: three outfits in one Swap

The source is our own 12-second red-carpet clip (720x1280), made with AI and saved as a template in our account. It moves from a fire escape to a car to a red carpet, with a different look in each, under the caption "can't tonight, way too much going on". We typed this into "What to change", word for word:

Change her outfits and keep her the same woman: on the fire escape, the grey sweatshirt becomes an oversized cream cable-knit sweater; in the car and on the red carpet, the gold satin gown with long gloves becomes a deep emerald velvet gown with long black satin gloves, and the long cream coat becomes a long black tailored coat. Keep her face, hair, every shot, cut, camera move and pose. Keep the on-screen caption text exactly as it is.

We ran it as one job on Seedance 2.5 at 720p. It took about 6 minutes and cost 2,340 credits. The source runs 12.04 seconds and each render bills whole seconds, rounded up, so that is 13 billed seconds x 180 credits, the Seedance 2.5 Swap rate at 720p.

All three outfits changed as written. Shots, cuts, poses, camera moves and timing line up with the original. Her face, hair and earrings stayed, and so did the car, the chandeliers, the gold columns, the petals and the caption.

Two details drifted: the phone moved from her shoulder to her hand, and her shoes turned black, which the brief didn't ask for.

How to change an outfit in a video with Swap

1. Open Swap. It's the first card on the Make videos page.

2. Add the clip. Upload a file up to 100 MB, paste a TikTok link or pick a template. Swap keeps the full length, up to 45 seconds, so trim a longer clip first.

3. Write the change in "What to change". Name each look and the scene it's in. To change only the opening look, tap New outfit under the box to add this sentence, then edit it:

   Change the opening outfit to a fresh, put-together look: a white tee under an open light-blue denim shirt, beige straight-leg trousers and clean white sneakers.

   A video with an outfit change keeps its later looks unless you name them too.

4. Optionally, change who wears it. With no character picked, the original person stays. Pick a saved character to replace her, keep the outfit lines in "What to change" and take her face out of the keep-line. Our Seedance character swap guide shows how to set one up.

5. Pick an engine. A paid Swap defaults to Seedance 2.5 at 720p, the settings we used. Free accounts can Swap on Seedance 2.0 Fast 480p, Seedance 2.0 480p or MiniMax H3 768P.

6. Check the price and submit. The page shows each engine's rate per second, then the billed seconds and credit total, before you tap Riff it →.

How to write an outfit brief

• Name each look and where it appears. "On the fire escape" and "in the car and on the red carpet" tell the model which outfit goes where.
• Give each piece a color, a fabric and a cut. "Deep emerald velvet gown" and "oversized cream cable-knit sweater" leave little to guess. Name the accessories you want too, like "long black satin gloves".
• End with a keep-line. Ours listed her face, hair, shots, cuts, camera moves, poses and the caption. Her face, hair, cuts and caption all held.
• Expect unnamed pieces to follow the new look. Her shoes turned black with no word about shoes in the brief. If shoes, a bag or the way she holds a prop matter, name them. Next time we'd add the phone on her shoulder to the keep-line.

What it costs, and how to start free

Swap bills per second of finished video, at its own rates:

Each render bills whole seconds, rounded up. Failed renders aren't charged, and if a run fails partway, only the seconds already rendered are billed. Seedance 2.5 at 480p is half its 720p rate, so a 480p draft lets you check a brief before the final. Plans start at $15 a month for 3,000 credits.

New accounts start with free credits, no card needed, and can Swap on Seedance 2.0 Fast 480p, Seedance 2.0 480p or MiniMax H3 768P. A short clip comes back whole; most longer ones start with a free first section, and a plan finishes the rest. Seedance 2.5, 720p and above, and H3 at 2K come with a plan. Riffkit adds no watermark on any plan. So far we've run this outfit brief on Seedance 2.5 only.

Rights: use footage you own

The red-carpet footage is ours; we made it with AI. Its soundtrack is the original TikTok's music, and Swap keeps the source's music, so this comparison is silent. Use your own footage or footage you have the rights to. The people and music in someone else's TikTok still belong to them, new clothes or not. For someone else's winner, Adapt, Riffkit's other mode, keeps the formula and makes new footage. Adapt keeps the source's music by default, so pick "Reference original BGM" for an original track in that style.

Try it on your own clip

Open Swap, add a clip of your own up to 45 seconds, tap New outfit or name each look, and submit. For a whole new look, the same clip restyled as 90s anime is in our video to anime guide.
