Abstract
Video content creation and production has reached the masses, as almost everyone is now able to create video dips on a daily basis. Video editing is a natural and necessary operation that is most commonly employed by users after video capture. Wireless imaging and video capturing devices, with hardware constraints of memory and processing power, are unable to accommodate conventional spatial domain video editing. In this paper we present a set of algorithms for efficiently performing editing effects on video content. The proposed algorithms, covering intra and inter sequence operations, are applied on H.263 and MPEG-4 compressed video sequences. The techniques ensure that the desired effects are achieved generating standard compliant codestreams, with significant savings in computations compared to the convention approach based on spatial domain editing.
