While some of the footage shot for "It's All True" was repurposed or sent to stock film libraries, approximately 200,000 feet of the Technicolor nitrate negative, most of it for the "Carnaval" episode, was dumped into the Pacific Ocean in the late 1960s or 1970s. In the 1980s a cache of nitrate negative, largely black-and-white, was found in a vault and presented to the UCLA Film and Television Archive. A 2000 inventory indicated that approximately 50,000 feet of "It's All True" had been preserved, with approximately 130,045 feet of the deteriorating nitrate not yet preserved.
