The invention discloses a period-adjustable variable-speed special effect rendering method and system and related components thereof, and the method comprises the steps: obtaining a to-be-processed initial video, and a starting position and an ending position of a special effect action segment in the initial video, and calculating the target duration of the special effect action segment according to the starting position and the ending position; obtaining the target duration of the special effect action segment, comparing the target duration with a preset duration parameter, and taking the minimum value of the target duration and the preset duration parameter as the actual duration of the special effect action segment; and calculating a time variable according to the actual duration, calculating an execution speed of the special effect action segment by using a rhythm function, and executing the special effect action segment according to the execution speed. According to the invention, the actual duration of the special effect action segment is adjusted through the preset duration parameter, and the time variable is calculated based on the actual duration, so that the execution speed is calculated, and the variable speed special effect action segment playing effect with an adjustable period is achieved.
Description
technical field [0001] The invention relates to the technical field of graphics special effects rendering, in particular to a variable speed special effect rendering method and system with adjustable period and related components thereof. Background technique [0002] Special effects rendering has a wide range of application scenarios in the field of short video editing. Adding opening and closing special effects during opening and closing can make short videos more overall observable. At present, the opening and closing special effects of clipping have not opened any special effect parameters, and it is difficult for users to adjust the playback speed of the opening and closing actions within a fixed action duration. [0003] The existing opening and closing special effects clipping methods have defects in processing the opening and closing rendering logic: the opening and closing actions all start at the first frame of the special effect action segment and end at the last ...
