AI Trailer Generator

Quick answer: A trailer is a short script of moments, not the whole story. Write 60 to 120 seconds in three beats (the world, the disruption, the rise) and a final button, set the type to Film, and SceneMixer draws the cast once, storyboards each moment and renders the trailer with a narrator and a score. If the story already exists as a project, reuse its cast so the trailer and the film match.

Brief for AI Create: A 90-second trailer for a mystery series: a village where every clock stopped at 4:12 on the same night twenty years ago; a returning daughter, a narrator, the title spoken at the end.

Beat	Seconds	What it does
The world	15–25	Calm. Who, where, what is normal.
The disruption	20–30	The thing that changes everything, in one clear image.
The rise	25–45	Shorter shots, bigger moments, the stakes out loud.
The button	5–10	Silence, one last line, then the title.

Trailers for different things

Trailer for	What to show	Guide
A film or short	Three or four key scenes with the real cast	Movie trailer
A TV pilot pitch	The world, the hero, the hook, the conflict	Pitch trailer
A book	Mood and premise without spoiling the ending	Book trailer
A game or tabletop campaign	The world and its stakes, original characters	Write it as a short script
Your own series	The season's best moments	Reuse the series' cast

Same faces as the real thing

A trailer made in a separate project can pick its characters, places and voices from your library, so the hero of the trailer is the hero of the film. Reuse characters across projects.

Titles and text

Video models are unreliable at drawing legible words, so let the narrator speak the title, or add it in an editor afterwards. For the poster, Cover art paints the title into a key visual. AI movie poster.

Cost

A 90-second trailer is 90 seconds of video: on the default tier that is 990 credits including the join, before retakes. Trailers have many short shots, so plan a retake or two for the key moment.

In SceneMixer vs. stitching tools together

Most AI drama workflows are five or six tools in a row. This is where each step happens here, and what it replaces.

Step	In SceneMixer	Doing it by hand with separate tools
Script and episode plan	Paste a script or a novel, or type one line: it is read into a cast, locations, props and an episode outline you can edit	A chat model writes the script; you split it into episodes and carry the text from tool to tool
Character faces and places	Every character, location and prop is drawn once as a reference sheet and attached to every shot it appears in	An image model, one sheet at a time; you upload the right reference to every clip yourself
Shots	A storyboard per episode with numbered shots and seconds; video is generated segment by segment in 9:16 or 16:9 against the same sheets	A video model, one clip per prompt, describing the same people again each time
Voices and dialogue	Lines are performed in the video itself, one voice per character, in any of 15 languages	A text-to-speech tool for each line, then a lip-sync pass on every clip
Fixing one shot	Edit that shot's text and regenerate the segment alone; the rest of the episode is untouched	Regenerate the clip, then re-cut the timeline
Finishing	Segments are composited into one episode file with its score; members download without the AI badge	A video editor to join the clips, add music and captions, then export
Publishing	You upload the finished episode to TikTok, YouTube, Instagram or anywhere else; nothing is posted for you	Upload by hand, the same as here

Can you make money with AI dramas on TikTok and YouTube?

Yes, within each platform's rules, and the rules are about the account and the video, not about how the video was made. TikTok's Creator Rewards Program (checked November 2, 2026) is open to personal accounts aged 18+ in the United States, United Kingdom, Germany, Japan, South Korea, France, Mexico and Brazil with at least 10,000 followers and 100,000 video views in the last 30 days; a rewarded video must be original, longer than one minute and reach 1,000 views on the For You feed. YouTube's Partner Program needs 1,000 subscribers plus either 4,000 watch hours in the last 12 months or 10 million Shorts views in the last 90 days.

Both platforms require realistic AI-generated content to be labelled, and YouTube states that disclosing AI use alone does not limit a video's audience or its eligibility to earn. SceneMixer episodes are longer than a minute by design, carry an AI badge by default (members can switch it off and add the platform's own label instead), and are yours to publish. The full answer, with sources.

FAQ

Can AI make a movie trailer?

Yes. Write a short trailer script; it is cast, storyboarded and rendered with a narrator and score.

How long should a trailer be?

60 to 120 seconds: three beats and a final button.

Can the trailer use my film's characters?

Yes. Pick them from your library in the trailer project.

Can it write the title on screen?

Not reliably. Have the narrator say it, add it in an editor, or use the poster for the title.

Is there music?

Yes. A score is added under the voices; it can be switched off.

Can I make a trailer for someone else's film?

Only original material; famous films and characters are refused.

Is SceneMixer like ReelShort or DramaBox?

No. ReelShort and DramaBox are apps for watching short dramas. SceneMixer is for making them: it turns your script or novel into episodes with a consistent cast and spoken dialogue, and you publish the episodes wherever you like, including those platforms' creator programmes where they exist.
