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.

Abstract: The video sending method includes: acquiring a video stream to be transmitted; generating consecutive frame groups from the video stream, wherein setting a first frame in the current frame group to be a long-term reference frame that uses a first frame in a previous frame group as a reference during generation of at least one of the current frame group, wherein the long-term reference frame is a predictive coded frame configured to transmit a difference and a motion vector obtained by performing a comparison against the first frame in the previous frame group, the current frame group is a frame group other than the first frame group; and sending the frame groups to a receiving terminal. The video receiving method comprises: receiving the frame groups sent by a sending terminal; and restoring the frame groups to obtain the transmitted video stream.
