When a user records a video through the electronic equipment, the electronic equipment continuously detects display content in a video recording interface, the display content is related to a shooting object in the video recording process, and under the condition that the video recording interface comprises the target object, a video index is generated, and the playing time corresponding to the video index is the time of shooting the target object. After the first video is obtained through recording, the electronic equipment can obtain the first video with the video index according to the generated video index and the first video. The user can start playing the target video from the time of the corresponding target object entering the mirror by clicking the video index.

The target object is a shooting object in the shot video and can be selected from a person, a scenery and the like.

The video index may represent an identifier of a target object, and the video index corresponds to the mirror-in time of the target object, and a user may skip the target video to the mirror-in time of the target object to play by clicking the video index, and it can be understood that the user may adjust the playing progress of the target video by clicking the video index. The first video is a video obtained by video recording.

The target video comprises the automatically generated video index, and a user can start playing the target video from the playing time corresponding to the video index by operating the video index.

The preset identification list is a list stored in advance by a user, and comprises a plurality of first target identifications and input characteristics of first input corresponding to the first target identifications. Wherein the input feature is associated with an input form of the first input. Illustratively, in the case that the first input is a voice input, the input features are voice contents, and in the preset identification list, a plurality of voice contents correspond to a plurality of first target identifications one by one. And under the condition that the first input is a sliding input, the input characteristic is a sliding track, and in the preset identification list, a plurality of sliding tracks correspond to a plurality of first target identifications one to one.

It should be noted that, before the video recording starts, a preset identifier list is obtained, where the preset identifier list is a first target identifier list of a target object that is entered in advance in an electronic device by a user, and the entry manner of the first target identifier may be in various manners, specifically, may be in a voice manner, a manual typing manner, or an image with first target identifier information.
