AI game trailer makers: what AI can and cannot do for a trailer
2 min read
By Eduardo Orellana ·
An AI trailer tool is useful when it works from your real gameplay: finding the best moments in hours of footage, cutting to a track's beats, writing short title cards, reframing for 9:16, and making several cuts to test. It is a liability when it generates footage of a game that does not exist: Steam asks for trailers that show the game, and players notice. Use AI for the edit, keep the footage real, and judge the cut yourself.
The footage must be the game
Generated video can make a trailer for any game, including one you have not built. That is the problem: a trailer that shows what the game is not sets up refunds and reviews that say so. Valve also recommends the first trailer be mostly gameplay with the HUD visible. The useful AI tools edit real footage rather than imagine it.
What AI does well
- Finding highlights: kills, near misses, big moments, in hours of capture.
- Cutting to the beats of a licensed track.
- Short title cards and the end card.
- Reframing a 16:9 trailer to 9:16 for TikTok and Shorts.
- Several versions with different openings, to test which hook works.
What it does not
Choose the one thing your game should be remembered for, judge whether a moment is actually exciting, and know which footage is outdated. Those stay with you.
Kinds of tools
- General AI video editors: auto-cut and captions; they do not know your game.
- Clip finders for streams: good at highlights, weak at structure.
- Game-aware tools: work from the game itself, so footage and context match.
