Abstract:
A video editing apparatus comprising:a scene information input means for inputting scene information, where a scene is a plurality of consecutive frames extracted from an edit stream; a re-encoding target picture selector for selecting as target pictures for re-encoding the smallest number of pictures that must be re-encoded for the scene to be independently reproducible; a stream structure data generator for generating structure information for a stream in a range containing a target picture and an intra-coded picture referenced for coding the target picture; a buffer fullness calculating means for calculating, from stream structure data, buffer fullness at a target picture boundary to a recycled picture not requiring re-encoding; a re-encoding range code allocation calculator for calculating a code allocation to a re-encoding range based on buffer fullness and target picture count, said re-encoding range being one or a plurality of target pictures near an edit point between scenes; a re-encoding target picture target code size calculating means for calculating a code allocation to each target picture based on the re-encoding range code allocation, target picture count, and picture type after re-encoding; and a scene linking means for connecting scenes and producing a new stream.
