# How to change clothes in a video with AI

**How do I put different clothes on a person in a video with AI?**

Use a video virtual try-on model. Decart Lucy 3.5 VTON takes your clip and an image of the garment, and returns the same clip with the person wearing it, at 720p. For other changes to a person, a general video edit model such as Kling O3 Video Edit takes a prompt instead of a garment image.

## Models that do this

| Model | Maker | Pick it for | Takes | Credits per run |
|---|---|---|---|---|
| [Lucy 3.5 VTON](https://otoy.studio/models/decart-lucy) | Decart | Garment image onto a person in a video | Prompt plus video or image | 37 (from €0.37) |
| [Kling O3 (Video Edit)](https://otoy.studio/models/kling-o3) | Kuaishou | Prompt-based edits, up to 4K | Prompt plus video or image | 174 to 696 (from €1.74) |

The lowest-cost option here is **Lucy 3.5 VTON**, from 37 credits (€0.37) per run. Credits are OTOY Studio's currency: 1 credit = €0.01. Prices are list prices before plan discounts (paid plans take 10% to 25% off every run). Every model is on every plan, including Free.

## How to do it in OTOY Studio

1. Upload the clip of the person.
2. Upload a clean image of the garment, ideally on a plain background.
3. Add the Lucy 3.5 VTON node and connect both.
4. Run it. Use Topaz Video Upscale afterwards if you need more than 720p.
