[0003] However, the traditional video clip generation method requires the user to manually specify the time slice. When the user finds a favorite clip and wants to capture it, it is difficult to find the corresponding location, and a video is often relatively long. If there are many favorite clips in the middle that need to be intercepted, Need to find out one by one, the operation is cumbersome, if you see the clip you like, stop watching and intercept immediately, although you can find the location, but it will affect the effect of playing the video and bring inconvenience to the user

Embodiment 3
[0057] In the third embodiment, as image 3 As shown, when the interception type is a screenshot, a method for generating a video clip includes the following steps:
[0058] Step S300, playing a video file.
[0059] Step S310, capturing the user's facial expression data in real time, and comparing the captured facial expression data with typical expression element data in the facial feature database. Capture the user's facial expression data through a video input tool such as a camera.
[0060] Step S320, judge whether the facial expression data is typical expression element data, if so, execute step S330, otherwise, execute step S340.
[0061] Step S330, generating an interception start command, obtaining an interception type as a screenshot, capturing a picture, and saving it to a set path.
[0062] Step 340, judging whether a screenshot operation is in progress, if yes, execute step S350, otherwise end.
[0063] Step S350, generating an interception end instruction.
Embodiment 4
[0064] In embodiment four, such as Figure 4 As shown, when the interception type is continuous shooting, a method for generating video clips includes the following steps:
[0065] Step S400, playing video files.
[0066] Step S410, capture the user's facial expression data in real time, and compare the captured facial expression data with the typical expression element data in the facial feature database. Capture the user's facial expression data through a video input tool such as a camera.
[0067] Step S420, judge whether the facial expression data is typical expression element data, if yes, execute step S430, otherwise, execute step S440.
[0068] Step S430, generating an interception start instruction, and obtaining the interception type as continuous shooting.
[0069] Step S440, judging whether continuous shooting is in progress, if yes, execute step S450, otherwise end.
[0070] Step S450, generating an interception end instruction.
[0071] In step S460, a series...

Abstract
The invention relates to a method and system for video clip generation. The method comprises the following steps: playing a video file; capturing facial expression data of a user in real time and comparing the captured facial expression data with typical expression element data in a facial feature database; and intercepting the video according to the comparison result to obtain a video clip. According to the method and system for video clip generation, when the video file is played, facial expression data of a user are collected in real time; the collected facial expression data are compared with the typical expression element data in the facial feature database; and according to the comparison result, the video is intercepted to obtain the video clip that corresponds to the typical expression element data. Therefore, a needed video clip can be intercepted accurately and a playing effect is not influenced.
Description
【Technical field】 [0001] The invention relates to video processing technology, in particular to a method and system for generating video clips. 【Background technique】 [0002] The traditional method of generating video clips is to specify the time slice by the user, such as selecting the start time point and the end time point, and then the video editingsoftware intercepts and generates the original video based on the time slice specified by the user. [0003] However, the traditional video clip generation method requires the user to manually specify the time slice. When the user finds a favorite clip and wants to intercept it, it is difficult to find the corresponding location, and a video is often long. If there are many favorite clips in the middle that need to be intercepted, Need to find out one by one, the operation is loaded down with trivial details, if see the segment that likes then stop watching immediately and intercept, although can find the position, influence...
