The invention discloses a time axis calculation method and device, electronic equipment and a storage medium. The method comprises the steps of acquiirng a time axis calculation request and determining a video file matched with the time axis calculation request; In all video materials associated with the video file, obtaining a to-be-calculated video material needing to be labeled with time axis information; Playing the video file, and carrying out screenshot on all image frames contained in the video file; and according to a preset identification algorithm, identifying image contents of all image frames, and calculating time axis information of the to-be-calculated video material in the video file according to an identification result. According to the embodiment of the invention, the time axis of pictures and characters in the video file is calculated manually in the prior art; The method solves the problems that an existing time axis calculation scheme is time-consuming and labor-consuming, and the accuracy of the time axis is difficult to guarantee, can optimize the existing time axis calculation scheme, can automatically calculate the time axis of the video material in the video file, and improves the calculation accuracy of the time axis.
