Embodiment 1

[0076] Figure 1a It is a flow chart of a method for adding video special effects provided by Embodiment 1 of the present disclosure. This embodiment is applicable to the situation of adding video special effects to videos. The method can be executed by a device for adding video special effects, and the device can use software and / or or hardware, the device can be configured in a terminal device, such as typically a computer or a mobile terminal. Such as Figure 1a As shown, the method specifically includes the following steps:

[0077] S110. Acquire at least one image frame in the video, and identify at least one target human body joint point of the user in the image frame.

[0078] Generally speaking, video is formed by a series of static image frames played continuously at a very fast speed. In this way, the video can be split into a series of image frames, and an editing operation can be performed on the image frames, thereby realizing the editing operation on the video. ...

Embodiment 2

[0108] figure 2 It is a flow chart of a method for adding video special effects provided by Embodiment 2 of the present disclosure. This embodiment is embodied on the basis of each optional solution in the foregoing embodiments. In this embodiment, acquiring at least one image frame in the video is embodied as: acquiring at least one image frame in the video in real time during the video recording process. Simultaneously, adding a video special effect matching the starting joint action condition at the video position associated with the target image frame in the video is embodied as: using the video position of the target image frame as a special effect A starting point is added, and a video special effect matching the starting joint action condition is added in real time to the video. At the same time, during the video recording process, at least one image frame in the video is acquired in real time, and the image frame in the video is presented in real time on a video pre...

Embodiment 3

[0124] image 3 It is a flow chart of a method for adding video special effects provided by Embodiment 3 of the present disclosure. This embodiment is embodied on the basis of each optional solution in the foregoing embodiments. In this embodiment, the video special effect matching the initial joint action condition adds a special effect to the musical instrument of the set musical instrument type. Before adding the video special effect matching the initial joint action condition in the target image frame, the optimization is as follows: if it is determined that the video special effect matching the initial joint action condition is to add a special effect to a musical instrument of the set instrument type, Then determine the user's human body characteristic information according to the at least one target human body joint point; determine the initial special effect parameters matching the musical instrument added special effect according to the human body characteristic info...

Abstract

The disclosure discloses a video special effect adding method, device, terminal equipment and storage medium. The method includes: acquiring at least one image frame in the video, and identifying at least one target human body joint point of the user in the image frame; if it is determined that the target human body joint point identified in the target image frame satisfies the preset initial Joint action condition, then obtain the video special effect matching the initial joint action condition; add the video special effect matching the initial joint action condition at the video position associated with the target image frame in the video. The embodiments of the present disclosure can add matching dynamic special effects to the joint points of the user, so as to improve the scene diversity of the video interactive application.

Description

technical field [0001] Embodiments of the present disclosure relate to data technology, and in particular, to a method, device, terminal device, and storage medium for adding video special effects. Background technique [0002] With the development of communication technology and terminal equipment, various terminal equipment such as mobile phones and tablet computers have become an indispensable part of people's work and life, and with the increasing popularity of terminal equipment, video interactive applications have become a The main channel of communication and entertainment. [0003] At present, video interactive applications can recognize the user's face, and add a static image on the user's head (such as adding a headgear to the hair) or add facial expressions to cover the user's face. This method of adding images is too limited, and at the same time, the application scene is too single to meet the diverse needs of users. Contents of the invention [0004] Embodi...
