The advent of digital broadcasting and the next electronic television transition are in the process of relegating analog video on the standing of a legacy engineering in many areas of the earth. The development of large-resolution video cameras with improved dynamic range and coloration gamuts, combined with the introduction of large-dynamic-assortment electronic intermediate knowledge formats with improved shade depth, has triggered electronic video know-how to converge with film technological know-how. Considering the fact that 2013,[update] the use of digital cameras in Hollywood has surpassed the usage of movie cameras.[seven]
