Problems solved by technology

[0002] In the process of video production, special effect processing is a crucial link. The existing special effect processing functions are single and rigid. For each frame of the video stream, only one special effect can be selected for overall transformation. In this way, when the video is played, Only one special effect can be displayed. If multiple special effects are to be displayed, one special effect must be completed, packaged into a file, and then the second special effect transformation is performed on the new file, and so on. The procedure is complicated and consumes a lot of unnecessary time, which cannot meet the occasions with high real-time requirements, and multiple times of packaging into files will cause the degradation of video quality
The existing special effect processing methods cannot select multiple areas, and cannot perform different special effect transformations on these selected areas, let alone perform more than two special effect transformations on the same area. Meet the needs of users

Abstract

The invention discloses a method for outputting various stunt effects simultaneously. The method includes, in particular, selecting at least one material segment area from a material source; storing the material source in a material source memory; adding stunts to the at least one material segment area to obtain stunt intermediate processing effects of the at least one material segment area; storing the stunt intermediate processing effects of the at least one material segment area in corresponding intermediate processing effect memories respectively; overlaying the stunt intermediate processing effects of the at least one material segment area in the intermediate processing effect memories and the material source in the material source memory to obtain stunt final processing effects; and outputting the material source, the stunt intermediate processing effects of the at least one material segment area and the stunt final processing effects simultaneously. The method is capable of achieving simultaneous output of multichannel video streams of any stunt intermediate processing effects of any areas and the final stunt processing effects.
