Coordination: Alejandro Lázaro / Clara Martínez Malagelada

The way in which you present your film, or any audiovisual piece, is fundamental for its visualization and distribution. It is an essential letter of presentation and, surely, very decisive when creating a judgment about your work. It is not something minor but crucial for the good outcome of it.


The teaser or trailer is one of your cover letters. Who do you want to address it to? To the public? To a distributor? To a producer? To a festival? You must consider several factors that guarantee a success to reach who you consider and in the most appropriate way. You must have knowledge about the different screens where your finished project will be shown. What kind of audiovisual piece do we have? We must define it, conceptualize it, synthesize it, and know what we want to do with it.


How many trailers have we seen that do not reflect what we will find later on screen? Is that what we want? Are we interested in that? What tools do we need to reach our end?
The teaser as a provocation, as a claim, as a wake-up call. The trailer as an extension of what you want to tell, as a concept that defines your project. As a structured narrative that summarizes our piece. We will try to address these issues in a theoretical and practical way, with our own and representative examples. We believe that practical implication is essential to teach this process in person, so that the students can share together with us the route from the idea to the final teaser / trailer.
