A teaser trailer typically lasts between 30 seconds and 90 seconds and provides a brief insight into the film's plot through clips and glimpses of main characters, without revealing too much dialogue. It aims to entice audiences with a quick pace that may start slow and then quicken, using buzz words, indications of release dates, and tags to build mystery and intrigue around the film's genre and story. Production studios and distributors are usually identified at the beginning or end to establish authenticity.
