Video Relighter changes the lighting of a video while preserving the original composition, camera movement, subject motion, and scene structure. Choose a daylight or night lighting preset, set the sun direction when applicable, and generate a relit version of the same shot without prompt writing.
Video relighting workflow
Change the lighting of an existing video while keeping the original shot structure intact.
Daylight and night presets
Choose from daylight looks such as hard_sunlight, golden_hour, or overcast, or night styles such as moonlight, street_lights, or city_glow.
Sun direction control
Set where the sun comes from for daylight presets using sun_direction.
Outdoor scene enhancement
Relight landscapes, streets, drone footage, outdoor people shots, and other exterior scenes.
Multiple output resolutions
Choose 480p, 720p, or 1080p while preserving the original aspect ratio.
Seed support
Set a seed when reproducible relighting results are needed.

time.sleep(2)Video Relighter is a WaveSpeedAI model for video editing, exposed as a REST API on WaveSpeedAI. Video Relighter re-lights outdoor footage to a chosen lighting preset and sun direction, or re-renders the same shot at night, keeping composition, camera movement and subject motion intact. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates Python, JavaScript, and cURL examples for submitting requests and polling results. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/video-relighter.
Video Relighter starts at $0.2 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `video`, `seed`, `lighting`, `sun_direction`, `target_resolution`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/wavespeed-ai/video-relighter.
Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.
Commercial usage rights depend on the model's license, set by its provider (WaveSpeedAI). Check the provider's applicable terms and WaveSpeedAI's Terms of Service before commercial use.
