You see it regularly on YouTube: a video titled "Official Teaser Trailer" or "Final Trailer". But what do these terms actually mean? There is sometimes confusion around the different types of promotional material studios release for a film. In this article we explain the difference between a teaser, an official trailer, a TV spot and other variants — so you always know exactly what you are watching.
The teaser: sparking curiosity
A teaser trailer — or simply a teaser — is the first promotional video a studio releases for an upcoming film. The name says it all: it is meant to "tease", to spark curiosity without giving too much away. Teasers are generally shorter than official trailers — typically between thirty seconds and a minute and a half — and rarely reveal much about the plot.
A good teaser does one thing very well: it creates the emotion of anticipation. That can happen through an iconic image, a familiar melody, a glimpse of a lead character or simply an atmospheric build of tension. Think of the first teaser for Star Wars: The Force Awakens (2014), which set the world on fire with nothing more than thirty seconds of footage and iconic John Williams themes.
Teasers are often released long before the film arrives in cinemas — sometimes more than a year in advance. At that point, production is often still in full swing, and studio marketing teams simply don't yet have enough finished footage for a full trailer.
The official trailer: selling the film
The official trailer — also called a "full trailer" or "theatrical trailer" — is the main promotional video for a film. Where the teaser leans more towards atmosphere and intrigue, the official trailer has a clearer narrative structure. It introduces the main characters, sketches the central conflicts and gives the audience enough of the story to understand what kind of film this is — without giving away the ending or all the surprises.
An official trailer typically runs between two and two and a half minutes. It follows a specific three-part structure: a calm opening that introduces the world and characters, a middle section that raises the stakes and conflict, and an explosive finale — the so-called "money shot" — ending with the film title. Music plays a crucial role at every stage of this structure.
Studios sometimes release multiple official trailers for a major film. The first official trailer drops six to nine months before the release date. As the release date approaches, a second and third trailer may follow, each with slightly different footage or emphasis — depending on what previous trailers have revealed and which audience still needs to be reached.
The TV spot: compact and direct
A TV spot is a shorter, more compact version of the trailer specifically optimised for television broadcasts. TV spots typically run thirty to sixty seconds and are edited at a high pace aimed at immediate impact. They are deployed in the final weeks and days before a film's release, when the marketing campaign is at its peak.
TV spots sometimes contain footage or scenes not found in the official trailers. Studios use TV spots strategically to reach specific audiences: an action-driven spot for sports programmes, a more romantic version for lifestyle channels, and a funny spot for comedy shows.
Overview: types of film promotion
- Teaser trailer: 30 sec – 90 sec, atmosphere and intrigue, early in the marketing cycle
- Official trailer: 2 – 2.5 min, narrative structure, 6–9 months before release
- TV spot: 30 – 60 sec, high pace, the final weeks before release
- Extended clip: 2–5 min, shows a complete scene from the film
- Featurette: behind-the-scenes material, interviews with cast and crew
- Final trailer: last official trailer, just before release
Extended clips and featurettes
Beyond teasers, trailers and TV spots, studios also release other promotional material. An extended clip shows a complete, unedited scene from the film — often two to five minutes long. This is used to showcase the quality of the dialogue, acting or a specific action sequence, and is popular on YouTube where viewers look for more depth than a trailer provides.
A featurette is a short behind-the-scenes documentary, usually five to ten minutes long, featuring interviews with the director, cast and crew. Featurettes are designed to generate buzz among a more engaged film-lover audience who wants to know more about the production process.
The "trailer for the trailer": a modern phenomenon
A relatively recent development is the so-called "trailer for the trailer" — a short five to fifteen second announcement posted on social media to signal that an official trailer is coming soon. This sounds absurd, but it is a deliberate marketing strategy: by drawing attention in advance, studios ensure that the actual trailer is already firmly in the spotlight at the moment of release.
Marvel Studios is one of the grand masters of this tactic. Every announcement of a new trailer — even the teaser of an upcoming teaser — generates hundreds of thousands of interactions on social media, creating extra visibility and anticipation.
What does this mean for Teasy?
For cinema programmers and film lovers who want to keep track of all relevant promotional material, this distinction matters. A teaser says something different from an official trailer, and a TV spot has a different function from an extended clip. Teasy makes it clear which type of material is available for each film, so you always know whether you're looking at the first glimpse or the full marketing picture.
