Change Day to Night, or Add Rain or Snow, in a Clip You Already Have
A 10-second clip on Wan 3.0 · 480P changed to Night costs 10 × 20 credits; on Wan 3.0 · 720P, 10 × 38.
What each option aims for
- Night — a deep blue-black sky, the scene lit only by its own lamps and lights, deep shadows, a quiet mood. A scene with no lamps in it gets very dark; see the tip below.
- Dusk — low warm orange light from one side, long soft shadows, a sky going from amber to violet.
- Daytime — bright neutral daylight, a clear sky, short soft shadows.
- Rain — visible rain, wet glossy ground with reflections, damp hair and clothes, grey overcast light.
- Snow — snowflakes drifting through the frame, a thin layer settling on surfaces, cold pale light.
- Clear sky — dry ground, a bright sky, crisp daylight. Use it to take rain or snow out.
Step by step
- Select the segment; under the player open Edit this clip → AI visuals.
- For a clip longer than 15 seconds, choose First half or Second half.
- Click Time of day or Weather, then the option.
- Check the price on Edit into a new version and press it. It usually takes a few minutes.
- Watch the new version. If the old one was better, switch back in Version History.
Night and lamps together
Night lights the scene only from the light sources already in it. An interior with lamps, a street with lanterns or a room with a lit screen turns into a convincing night; an open field with nothing in it turns into a dark frame. If the scene has lamps or candles that are off in your clip, you can run Lights → Light them up on the night version as a second edit. Lights and background people.
One change per edit
Time of day and weather are two separate changes. For a rainy night, run Time of day → Night first and Weather → Rain on the result. Each run is charged, and the second AI-edited version replaces the first in the history (the generated clip stays). How versions are kept.
Keep the scene consistent
An AI visuals edit changes this clip only. The storyboard still says what it said, the location image is untouched, and the other segments set in the same place keep their own light. If a whole scene should be at night, it is usually better to change the Time or Weather line in each of those segments’ storyboards and regenerate them, so every segment and any later regeneration agree. Use AI visuals when one or two clips are off. The segment header fields.

| Daytime | Bright neutral daylight, short soft shadows | Turning a night clip into day |
| Rain | Visible rain, wet glossy ground, damp hair and clothes | Exteriors |
| Snow | Falling flakes, a thin layer on surfaces, cold light | Exteriors |
| Clear sky | Dry ground, a bright sky | Taking rain or snow out |
FAQ
Will the next segment match?
Only if you change it too. AI visuals edits one clip; change the storyboard and regenerate for a whole scene.
Can I make it night and rainy at once?
Not in one edit. Run Night, then Rain on the result; each is charged.
Does the dialogue change?
No. The lines, the movement and the timing follow your clip.
Can I choose an exact time, like 5 pm?
No. The options are Daytime, Night and Dusk. For anything more specific, edit the storyboard's Time line and regenerate.
Turn day into night
One change, a price on the button, and the daytime clip stays in the history.
