Show rain streaks on a window behind a still interior

1. Task and boundary

Add a restrained rainy-window atmosphere to an interior scene. Begin with droplets already visible on the glass and move only a few down short paths. The useful contrast is motion at the window against a still room, not a room or outdoor view that melts with the water.

The related droplet exercise concentrates on contact and merging. Here the focus is where the droplets belong: on one pane behind the interior objects, with a stable scene beyond it. See MiniMax H3 two-droplet prompt: contact, form a neck, then merge.

These are suggested visual beats, not guaranteed timing or model controls. Adapt the small movement to the supplied first frame and actual available settings.

2. Authorized first frame

Provide an authorized interior image with a clearly bounded window, a few visible droplets on its outer surface and a simple distant view. Include one still interior object in front of part of the pane. Avoid a pane already covered by opaque water or a foreground object hiding the whole window.

3. Use the generator

Open the image-to-video generator, provide your authorized first frame and paste the prompt. Check available settings and cost before submitting; this page does not upload or submit for you.

1. Opening: locate the glass boundary, foreground object and several original droplets.
2. Action: follow a few downward paths while comparing the room against the window frame.
3. Ending: check the changed droplet positions and the unchanged room geometry.

4. Prompt and timing

Use the supplied first frame with the camera fixed. Keep the original window frame, room and interior objects still. A few of the existing droplets on the glass slowly descend a short distance, leaving narrow wet trails on that same pane. Keep these trails within the visible glass area and behind the foreground interior object. Preserve the distant scene beyond the window. Allow small local optical distortion directly through a droplet, but do not bend or redraw the whole background. Do not add indoor rain, a sheet of water, camera movement or new objects. Finish with the room unchanged and a few droplets visibly farther down the pane; they may continue drifting slowly.

5. Inspect the output

Inspect the actual opening, motion and ending. For each criterion, record a frame or time and pass, fail or inconclusive; hidden details remain inconclusive.

• Moving drops and trails stay within the glass region and behind the interior foreground object.
• The window frame and interior object keep their original outlines and positions.
• At least one original droplet has a readable downward path rather than a sudden jump.
• Outside small droplet-covered areas, the distant scene retains its structure instead of flowing with the water.

6. Fix one failure

• If water appears on the interior object, clarify that the droplets lie on the pane behind it.
• If the whole view warps, reduce droplet density and keep distortion local to visible drops.
• If trails teleport, shorten their travel and use a clearer, more sparsely wet first frame.

7. Ending and limits

The room and window retain their starting composition while several original droplets sit lower on the glass.

This describes a visible atmosphere effect, not a verified weather or optical simulation. Blurred drops may not support individual tracking; mark those paths inconclusive.
