Abstract
(EN)
Disclosed by the embodiment are a method, device, apparatus for adding video special effects and a storage medium. The method comprises the following steps: acquiring original video sequence and at least one special-effect video sequence; when there are two or more special-effect video sequences, and the two or more special-effect video sequences have the same frame rate, inserting frames into the original video sequence and superposing the original video sequence with the special-effect video sequences at the same time; and when there are two or more special-effect video sequences, and the two or more special-effect video sequences have different frame rates, determining a target frame rate from the frame rates according to preset rules, inserting frames into the original video sequence according to the target frame rate, and then superposing the original video sequence with the special-effect video sequences.
