Abstract
Provided are a method, apparatus and device for adding a video special effect and a storage medium. The method includes: acquiring a source video sequence and at least one special effect video sequence; in the case where frame rates of the two or more than two special effect video sequences are same, inserting a frame into the source video sequence and superimposing the two or more than two special effect video sequences on the source video sequence at the same time; and in the case where frame rates of the two or more than two special effect video sequences are different, determining a target frame rate from the frame rates of the two or more than two special effect video sequences inserting frames into the source video sequence and then superimposing the two or more than two special effect video sequences on the source video sequence.
