Tribeca Film Institute, the nonprofit affiliated with the Tribeca Film Festival, is expanding its cross-platform multimedia programs with a series of workshops that launches next week in Cambridge, Mass.Tribeca already has a transmedia initiative including a grant program, and the festival will incorporate transmedia content into its 2013 edition. Tribeca is just one of several industry orgs that have recently highlighted a growing awareness of transmedia and new-media storytelling: Film Society of Lincoln Center, for instance, recently launched a programming initiative called Convergence that this year included a chunk of new-media-centric events during FSLC’s New York Film Festival. Tribeca’s new workshop series, Tribeca Hacks, aims to pull together creatives and tech specialists to fertilize new projects, tools and techniques. The Cambridge outing, set for Dec. 8, is presented with interactive storytelling group Zeega. Further outings for Tribeca Hacks in cities around the country, including Tribeca’s homebase of Gotham, are in the works for 2013.
