Start from a single line of text or a product photo. Pexo writes the script, generates every shot, and stitches them into one continuous, edited video.

Pexo automatically selecting the best AI model for a teaser trailer

10+ models, auto-picked

Every AI teaser trailer shot goes to its best model

Pexo runs across more than ten video engines, including Seedance 2.5, Kling AI 3.0, MiniMax H3, and Happy Horse 1.0, and routes each shot to the model that handles it best. Photoreal hero shots, stylized motion, fast camera moves, each goes to its strongest engine automatically. You can name a specific model when you want fine control, but most of the time you never think about it. You get the best quality available without comparing tools yourself.

How to make a teaser trailer that looks expensive

A teaser has to feel expensive in the first two seconds, so Pexo routes your shots across more than ten video engines, including Seedance 2.5, Kling AI 3.0, MiniMax H3, and Happy Horse 1.0, and sends each one to the model that nails that mood. Slow push-ins, hard cuts to black, a furious set piece, a single haunting image, each goes to its strongest engine automatically. You get moody depth of field, dramatic light, and controlled motion that reads like a marketing team cut it, whether it is a film teaser, a video game trailer, or a product reveal.

A score written for your teaser trailer

Pexo generates an original soundtrack tuned to the mood and pacing of your teaser trailer, so you are not digging through stock libraries or risking a copyright strike. Tell it the feel you want, energetic, cinematic, calm, and it scores the cut and mixes the levels under the narration automatically.

A teaser trailer maker that ships every aspect ratio

Pexo delivers your teaser trailer natively in 16:9 for YouTube, 9:16 for TikTok and Reels, and 1:1 for feeds, up to 4K and anywhere from 5 to 120 seconds. Each aspect ratio is generated fresh for that screen, with the composition framed for it rather than cropped down from one master. Ask for several formats at once and post the right version to every channel. It looks intentional everywhere it lands.

Marketers cutting teaser trailers with Pexo

I described the vibe and Pexo cut a teaser that looked like it came out of a real studio pipeline. Wishlists doubled in a day.

We needed a teaser before picture lock, and Pexo built one from the logline alone. It set the tone perfectly.

The music and the cuts hit together, so the teaser actually felt scored instead of pasted over stock. Our reveal post went viral.

Everything about AI teaser trailers

What is a teaser trailer?+

A teaser trailer is a short promotional clip that reveals very little and hints at a lot, built to spark curiosity before a full trailer or a launch lands. Teasers usually run 15 to 60 seconds. Pexo's AI teaser trailer generator takes your mood and your hook and returns a finished cryptic cinematic cut with visuals, an original score, and captions.

How long should a teaser trailer be?+

Around 15 to 60 seconds. That is noticeably shorter than a full two-minute trailer, and the tight runtime is what makes a teaser read as a withheld secret rather than a summary. Pexo generates anywhere from 5 to 120 seconds, up to 4K, so you can keep the teaser trailer short and still export a longer cut later.

Do I need footage or editing skills to make a teaser trailer?+

No. Pexo generates the shots, scores the cut, adds captions, and delivers a finished teaser trailer from a description alone, in 16:9, 9:16, and 1:1 up to 4K. Drop in a logo, a product photo, or reference footage if you have one, but nothing is required to start.

What is the best AI tool for a teaser trailer?+

Pexo. It runs more than ten video engines, including Seedance 2.5, Kling AI 3.0, MiniMax H3, and Happy Horse 1.0, and sends every shot to the engine that handles that mood best, then scores and captions the cut. One teaser trailer maker gives you 5 to 120 seconds in 16:9, 9:16, and 1:1 up to 4K.

How is a teaser trailer different from a movie trailer or a launch trailer?+

A teaser hints and withholds to build hype early, while a movie trailer shows more of the story and the stakes, and a launch trailer lands on release day. Many campaigns run all three in sequence, and Pexo cuts each one from the same description.

How do I write a good prompt for a teaser trailer?+

Use subject plus action plus camera movement plus setting plus style. Example: a lone figure walking toward a lit doorway, slow push-in, a derelict concrete corridor, moody cinematic light with heavy shadow. Name the runtime and the aspect ratio you want, then let Pexo route each shot to the strongest engine and score it.
