Abstract: A method for video clip extraction includes: obtaining a video, and sampling the video to obtain N video frames, wherein N is a positive integer; inputting the N video frames to a pre-trained frame feature extraction model to obtain a feature vector of each video frame in N video frames; determining scores of the N video frames based on a pre-trained scoring model; and extracting target video clips from the video based on the scores of the N video frames.

Abstract: A method for extracting a video clip includes obtaining a video and splitting the video into multiple clips. The multiple clips are input into a pre-trained scoring model, to obtain a score of each of the multiple clips. The scoring model is obtained by training based on data pairs including first clips and second clips, the data pairs including first clips and second clips are obtained based on labeled clips labeled with target attributes, and the target attributes include attributes that characterize clips as target clips or non-target clips. A target clip is extracted from the multiple clips based on the score of each of the multiple clips. An apparatus for extracting a video clip and a computer readable storage medium are also disclosed.

Abstract: A method is provided for loading a rendering engine of a browser on a mobile terminal. The method includes receiving a user interface installation file and a rendering engine file separately and independently when an update to the browser is needed, wherein the user interface installation file includes a user interface module and an interface adapter module. The method also includes installing the received user interface installation file. Further, the method includes loading dynamically a corresponding function file and an object library file in the rendering engine file through the interface adapter module when an application runs. The corresponding function file and the object library file are not compiled together with the user interface adapter module.
