Problems solved by technology

[0006] However, the current video editing work still relies on manual processing to a large extent, requiring editors to manually operate the nonlinear editing machine to select video clips for cutting
This kind of manual editing is still a very cumbersome work, because the existing non-linear video editing is to expand the video file frame by frame and edit it with frame precision.
Due to the huge amount of video data, the frame-by-frame editing of the video requires a lot of human interaction and computer calculations

Embodiment 1

[0041] refer to figure 1 , is a flow chart of a video automatic editing method described in Embodiment 1 of the present invention.

[0042] Step 101, collecting and encoding video source signals to generate video frames;

[0043] Usually the camera completes the acquisition task, and then encodes the signal captured by the camera.

[0044] There are many encoding methods, and MPEG encoding is more commonly used at present.

[0045] The MPEG compression standard is designed for moving images. The basic method is to collect and save the information of the first frame within a unit of time, and then only store the parts of the rest of the frames that have changed relative to the first frame, so as to achieve the purpose of compression. The MPEG compression standard enables compression between frames. Among multimedia data compression standards, MPEG series standards are mostly used. The MPEG series compression algorithm has developed from the early MPEG-1 and MPEG-2 to the cu...

Embodiment 2

[0057] refer to figure 2 , is a flow chart of a video automatic editing method described in Embodiment 2 of the present invention.

[0058] Step 201, collecting and encoding video source signals to generate video frames;

[0059] Usually the camera completes the acquisition task, and then encodes the signal captured by the camera.

Embodiment 3

[0069] The above-mentioned automatic video clipping method can be applied to many fields such as the production of movies and TV programs, and the live broadcast and on-demand of network video. Especially for network video live broadcast, since the live broadcast process has very high time requirements, this automatic editing method is very effective for improving the live broadcast efficiency.

[0070] The current webcasts almost all adopt streaming media technology, and streaming media refers to continuous time-based media using streaming technology in the network, such as audio, video or multimedia files. Streaming transmission technology is a network transmission technology that compresses continuous sound and image information and puts them on the website server, allowing users to listen to and watch while downloading, without waiting for the entire file to be downloaded to their own machine before viewing. .

[0071] Streaming media technology is widely used in all aspe...

Abstract

The invention provides a video clipping method and a video clipping device. By marking a video frame, the video clipping method and the video clipping device can automatically clip according to the mark in the video clipping process without manual operation and clip. Therefore, the video clipping method and the video clipping device realize the automation of video clipping, greatly improve the working efficiency and also lighten the work load of the clipping personnel.

Description

technical field [0001] The invention relates to the technical field of video editing, in particular to a video editing method and device. Background technique [0002] Editing is one of the processes in the production of movies and TV programs. After the film or program is shot, according to the development and structure requirements of the plot or program, the pictures and soundtracks of each shot are selected, arranged and trimmed, and then assembled according to the principle of montage and the order with the most screen effects to become A film with complete structure, coherent content, clear meaning and artistic appeal. Editing is the entire work of decomposition and reorganization of film or TV audio-visual materials, and it is also a re-creation during the production of a film or program. [0003] Video editing is divided into linear editing and nonlinear editing. Linear editing is a traditional editing method for TV programs. In traditional video editing, videotap...
