Abstract: Disclosed in the embodiments of the present disclosure are a video frame adjustment method and apparatus, and an electronic device and a storage medium. The method comprises: on the basis of a first video frame and a second video frame in an initial video, by means of quantifying a neural network, determining 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; on the basis of the first optical flow and the second optical flow, determining 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, and determining the intermediate frame according to two initial video frames, the third optical flow and the fourth optical flow; and inserting the intermediate frame between the two initial video frames. By means of the video frame adjustment method provided in the embodiments of the present disclosure, the aim of inserting a frame between two adjacent video frames can be achieved; in addition, a playing effect of a high-frame-rate video after frame insertion can be guaranteed.
