Real-Time Video Try-On
Generative AI try-on applied to a live video feed instead of a static photo, like a mirror that changes your outfit.
What is real-time video try-on?
Real-time video try-on applies generative AI try-on to a live camera feed: the shopper sees themselves on screen wearing a different garment, and the rendered clothing follows their movements like a mirror. It combines the fabric realism of garment transfer with the interactivity that was previously exclusive to AR try-on.
It is the emerging frontier of virtual try-on. Photo-based try-on is the production standard today; real-time video generation became credible in 2025-2026 with specialized models (such as Decart's Lucy series) that generate video frames fast enough to feel live.
How it differs from existing methods
| Photo try-on | AR try-on | Real-time video try-on | |
|---|---|---|---|
| Output | Static generated image | Live 3D overlay | Live generated video |
| Fabric realism | High | Limited | High |
| Interactivity | None (one result) | Full | Full |
| Compute cost | Seconds of GPU per image | Runs on device | Very high (GPU per frame) |
| Production maturity | Standard | Standard for rigid items | Emerging |
The hard parts
- Latency: each frame must be generated in tens of milliseconds; a diffusion model normally takes seconds per image.
- Temporal consistency: the garment must stay identical across frames, with no flickering folds or shifting patterns.
- Cost: per-frame GPU generation is orders of magnitude more expensive than one photo render, which currently limits deployment at e-commerce scale.
FAQ
Questions, answered.
Is real-time video try-on available for online stores today?↓
Mostly not yet at production scale. The models exist and demos are public, but per-frame generation costs make photo-based try-on the practical choice for storefronts today. Costs follow the usual trajectory of generative AI: down.
