Before a movie is released, filmmakers always release a snippet of scenes from the movie, leaving the audience extremely curious. That snippet of the movie is often called a teaser or trailer. Although people often confuse the terms teaser and trailer, let's clarify the truth about teasers and trailers in the following article!

1. What is a Teaser?

A teaser is simply a short promotional video for a movie, product, or music with a brief duration ranging from a few seconds to under 1 minute. Additionally, a teaser typically exhibits the following characteristics:
- These are the initial images or short videos used to advertise a movie or product.
- The content of a teaser usually consists of gripping, thrilling scenes from the movie or music video.
- Teasers are often released by producers before the product is completed, they may be randomly edited scenes or scenes shot before filming to advertise to the public.
- Short in duration, only about a few dozen seconds for a teaser, yet containing captivating scenes that stimulate the curiosity of the viewers.
- The time from releasing the teaser to the movie or product launch is quite long, it could be over 1 year from the teaser release to the movie premiere. Teasers may present an initial concept of the movie and may differ slightly from the finished product.
2. What is a Trailer?

Similar to teasers, trailers are created to advertise the movie. Additionally, trailers have the following characteristics:
- A trailer is a snippet of scenes from the complete movie about to be released.
- Trailer duration typically ranges from 1 to 4 minutes.
- Often advertised in cinemas before a movie starts.
- The content of a trailer may reveal some of the movie's plot.
- There may be multiple trailers for a movie with sequential numbers like #1, #2, etc. Subsequent trailers are usually longer than the previous ones.
- Since trailers are cut from the complete movie, the time between the trailer release and the movie premiere is usually short, less than 1 year.
3. Conclusion

So, are Teasers and trailers too different? Through the analysis above, we can see the similarities and differences between these two concepts. They are:
- Teasers and trailers are both video products released for the purpose of advertising movies, music products, etc.
- Both teaser and trailer are clips taken from within the movie or during the movie production, so both teaser and trailer may reveal part of the movie's content.
- However, the duration of a teaser usually ranges from a few seconds to under 1 minute, shorter than a trailer which typically lasts from 1 to 4 minutes.
- Teasers often evoke suspense and curiosity, while trailers tend to closely follow the movie's plot, giving viewers the feeling of watching the entire movie in a short time to decide whether to watch it or not.
- Teasers may be released less frequently or not at all after the official movie launch, but trailers are released more frequently and may replace teasers.
- Teasers usually release one version associated with the movie, while trailers may have multiple versions, with the latter parts often longer than the former.
- Teasers are often heavily edited compared to the movie content, so sometimes the visuals in the teaser may differ from the official movie. Trailers, on the other hand, have content with visuals more similar to the official movie.
