Rain Window AI Video Effect

Rain Window builds a moody, half-obscured moment: rain runs down a pane of glass between the camera and your subject, blurring the lights behind. The subject leans close to the glass, draws a slow line through the condensation with one fingertip, then looks out through it into the lens. The camera holds still in soft focus throughout, so the whole clip depends on the rain and the fingertip line doing the visual work.

In our test runs on MiniMax H3, a woman in an off-shoulder knit, seen through a rain-streaked window, raised her hand to the glass and looked out at the lens while the drops ran down. A man in a grey henley behind a rainy window pressed his hand to the glass and looked out through it. Both runs kept the rain layer consistent through the clip and the face clearly visible despite the glass and condensation between camera and subject.

Because this effect adds its own rain and glass layer over the frame, it works on essentially any portrait — you don't need an actual window or rainy scene in your source photo.

Five seconds on MiniMax H3 is only the default. Before you generate you can lengthen the clip, raise the resolution, or switch to one of the other models listed for this effect, such as Wan 3.0 for clips of up to 30 seconds or Seedance 2.0 for 1080p, and the Generate button shows the new price first. Our samples come from MiniMax H3, so expect a slightly different take on other models.

It suits a moody, cinematic opener, a quiet transition shot in a longer edit, or an atmospheric header for a rainy-day or melancholy-themed post.
