Her site-specific pieces in locations such as the Guggenheim Museum, Union Station and the Staten Island Ferry, led naturally to her work in video and film. In 1981 YOU LITTLE WILD HEART, to music by Bruce Springsteen, was Marta's first half-hour for television, followed by MOUNTAINVIEW, made in 1989 in collaboration with independent filmmaker John Sayles. Since 2005 she has self-produced over 25 short videodances, which have shown at film festivals nationally and internationally, releasing her debut feature film HER MAGNUM OPUS in 2017. In 2020 she directed and edited two short films with Island Moving Company of Newport, RI; OUT OF RUIN and THROUGH HER EYES: A NEWPORT NUTCRACKER REIMAGINED to be broadcast on RI PBS in 2020/21.
As part of a continuing commitment to making dance accessible to a wide audience, Renzi helped inaugurate the "Inside/Out" program of public performances at the Jacob's Pillow Dance Festival, and her Project Company makes frequent appearances for free outdoors in public spaces.
In 1992, Marta received a New York Dance & Performance Award (a "Bessie") for her dance VITAL SIGNS, and in 1995 was the first recipient of a Dancing in the Streets award as "a fearless explorer of all manner of unconventional sites, integrating art into everyday life." She was a 2013 Bogliasco fellow at the Liguria Study Center for Arts & Humanities and received a 2015 CSA grant from Rivertown Artists Workshop.
Marta has served on the Board of Advisors for the New York Foundation for the Arts and was a consultant for the New England Foundation for the Arts' program "Building Community Through Culture." In 2008 she joined the Board of Directors of Dance Films Association, a 50-year-old member-supported institution based in New York City.
Renzi has taught in Chile and Paraguay through the International Linkages program of the American Dance Festival and and is a seven-time recipient of Choreographic Fellowships from the National Endowment for the Arts. Her work has been funded by the Jerome Foundation, Metropolitan Life, Con Edison and the Trust for Mutual Understanding. In 2007 she received an SOS grant from the New York State Council on the Arts to participate in a workshop entitled Dance for the Camera. In August of 2008, Renzi presented a new quartet as part of "Through a Choreographer's Eyes", curated by Martha Myers at The Yard in Massachusetts, and returned for several years subsequently since to present new work.
In pre-history, Marta performed with Douglas Dunn & Dancers, in David Gordon's PickUp Company, with Kei Takei's Moving Earth and with Twyla Tharp on the film of HAIR. In theater she has collaborated with William Finn on IN TROUSERS, Andre Gregory in THE PRIMAVERA STRING QUARTET TONIGHT! and with Cecil MacKinnon on Shakespeare's ROMEO AND JULIET performed with the Prokofiev score played live by the Buffalo Symphony Orchestra.
