How to make an AI game trailer or cutscene

Quick answer: A game trailer is a 60- to 120-second film in three acts: the world, the hero, the threat, ending on the title. A cutscene is one scene with dialogue. SceneMixer makes both from a script: choose Game Engine Realism (sharp materials, no grain, like a next-generation engine) or Cel-shaded 3D for a stylised game, pick a set such as Cyber Metropolis, Wasteland, Starship or Dungeon, and your characters are designed once and kept in every shot. It is for your own game and your own characters; published game characters are refused by the IP check. No HUD or on-screen text is drawn; titles and logos go on a poster and in your edit.

Brief for AI Create: A 90-second trailer for a game about a salvage crew on a drowned Earth: the world (flooded towers), the hero (a diver who hears the city's old radio), the threat (a company that wants the signal); three acts, Game Engine Realism, ends on a black frame for the title.

Your characters, designed once

Describe the hero as a sheet would: build, face, scars, armour, the thing they carry. The sheet is drawn once and every shot is generated from it, so the diver in the first act is the diver in the last. Members can upload concept art as the reference and it is redrawn in the look. Factions get a costume style and a mark; vehicles and weapons are props with their own reference. Character sheet generator · Props and references.

The trailer, shot by shot

ActShot to adapt
The world[Shot 1] 4s: Wide shot, slow push in. Flooded skyscrapers at dawn, water lapping at the twentieth floor. Ambient: wind, a distant radio tone.
The hero[Shot 2] 3s: Medium shot. @Ines, the diver, surfaces beside a rusted sign, pulls off her mask. @Ines (quietly): It's still broadcasting.
The threat[Shot 3] 3s: Low angle. A corporate skiff with a searchlight sweeps the water. Ambient: an engine, a loudspeaker.
The turn[Shot 4] 2s: Close-up on @Ines. She dives.
The title[Shot 5] 3s: Wide shot, black water, a single light descending. Cut to black for the title card in your edit.

Camera language works when written into the shot: slow push in, low angle, orbit. Keep each shot to one move, and show the fight before and after, not the wound. Cinematic camera moves · Fights and crowds.

What it will not do

  • Published characters and franchises. Refused by the IP check. This is for your game.
  • HUD, menus, on-screen text. Not drawn reliably; add them in your edit, and put the title on a poster. Movie poster generator.
  • Gameplay footage. It generates cinematics from text, not captures from a build.
  • Gore. Violence is shown before and after; graphic injury is blocked. Content rules.
