Video Relighting
Relight a Video with AI
Change the illumination in footage you already shot. Select the moment and describe the light direction, color, intensity, or time-of-day look while asking the model to keep the subject, location, motion, and composition recognizable.
Relighting keeps the location and objects conceptually the same while changing the light. Use weather editing for rain, snow, or fog, and scene change when the location itself should change.

FAQ
What to know before uploading your clip.
What is AI video relighting?
AI video relighting generates a new lighting treatment for an existing clip from a text prompt. You describe the light and the scene details you want to remain recognizable.
Can I turn a daytime video into night?
You can request a day-to-night concept. New shadows, highlights, reflections, and dark areas can make the result less predictable, so review the generated range carefully.
What footage works best for relighting?
Readable subjects, visible surfaces, and a short selected range give the model a clearer task. Results still vary with movement, reflections, and occlusion. Use only footage you own or are authorized to edit.
