Abstract:
1. A method for dissolving an incoming scene of video information which comprises a sequence of fields or frame of compressed video information and an outgoing scene of video information which comprises a sequence of fields or frame of compressed video information using a computer-based authoring and editing module, comprising the steps of: a. applying DCT domain motion inverse compensation to obtain DCT coefficients for all blocks of video information which make up a last frame of said outgoing video scene; b. applying DCT domain inverse motion compensation to obtain the DCT coefficients for all blocks of video information which make up the first frame of said incoming video scene; and c. creating a first frame in a dissolve region from said DCT coefficients of said last outgoing frame and said first incoming frame, said dissolve region being made playable as a transition between said outgoing and incoming scenes during playback of a video containing said outgoing and incoming scenes of video information.
