Sci-fi prompts are AI video prompts for quickly creating scenes full of scientific imagination, such as spaceships and fleets, alien worlds, future cities, robots, and extraterrestrial life. In Carat, you generate scenes with video models like Seedance 2.0, then keep going with follow-up work such as editing the result, changing the aspect ratio, adding captions, or stitching multiple cuts together.
In sci-fi scenes, the world's internal logic, how the technology works, the sense of scale, and an air of the unknown create believability more than flashy screen effects. When choosing a prompt, it helps to check the era and tech level, how the camera conveys scale, visual elements like light, particles, and holograms, and the channel you'll use it on.
In Carat, you can build follow-up clips from a generated video, adjust it to short-form ratios, and add captions, music, and overlays to polish it into content ready to post.
