An electronic device, comprising:

• one or more processors;
• a storage apparatus, configured to store one or more programs;
• the one or more programs, when executed by the one or more processors, cause the one or more processors to perform a method, wherein the method comprises:
• determining, based on a first video frame and a second video frame in an initial video, a first optical flow from the first video frame to the second video frame and a second optical flow from the second video frame to the first video frame through a quantization neural network, wherein the first video frame and the second video frame are two adjacent initial video frames;
• determining, based on the first optical flow and the second optical flow, a third optical flow from an intermediate frame to the first video frame and a fourth optical flow from the intermediate frame to the second video frame, wherein the intermediate frame is an estimated video frame to be inserted between the first video frame and the second video frame;
• determining the intermediate frame according to the first video frame, the second video frame, the third optical flow and the fourth optical flow;
• and
• inserting, in the initial video, the intermediate frame between the first video frame and the second video frame to obtain a target video,
