The principal objective of this article is to approach the interactive and transmedia documentary as a new narrative practice constructed through other narratives composed by different registers (textual, visual, sounds, blogs, websites) that allows the potential for an interactive, multilinear and multifocal narrative. From this perspective, I am located in a reflection about the possibilities of producing knowledge from the mixed media. I understand the documentary practice and the ethnography as forms where theory, research and creation co-exist and are co-elaborated. At the same time I am interested in the interrogation on how this transmedial and interactive narratives are implicated in the emergence of new ways of understanding and approaching the documentary practice.
