Room Flood AI Video Effect

Water pours into the scene and the level rises fast, over the floor and the furniture. Within four seconds everything is underwater. The person stays calmly in place as they begin to float, with hair drifting and bubbles rising. The light turns deep underwater blue with shimmering ripples.

In our test runs on MiniMax H3, a grey-bearded man in a mustard cardigan sitting on a green velvet sofa in a bright living room watched water flood in over the floor at second one and rise past his neck by second two, and from second three the whole room was underwater in deep blue light, bubbles rising and his hair drifting as he sat calmly. In a second run, a white-bobbed older woman in red glasses and a royal blue wrap dress sitting on a pink velvet sofa in a bright living room watched water flood the floor at second one, rise past the sofa by second two and submerge the whole room by second two and a half, ending underwater with her hair floating and bubbles rising.

Works best on a photo of a person in an indoor or enclosed space with visible floor or furniture, since the rising water is clearest against objects. The flood and underwater look are generated, so the scene gets a strong blue color shift. Open outdoor scenes work too, but there is less to submerge.

It runs on MiniMax H3 for five seconds by default, and H3 itself goes up to 15 seconds and 2K if you want more. Studio also lets you move the same prompt to another model before you generate, such as Seedance 2.0 or Wan 3.0, and the price on the Generate button updates with every change. Our samples were all made on MiniMax H3, so other models will read the prompt in their own way.

Good for dreamy or dramatic scenes, and for turning an ordinary room photo into an underwater mood.

Change "deep underwater blue" to "deep underwater green" for a different tint, or change "within four seconds" to "within six seconds" for a slower flood.
