Embodiment 1

[0053] A video editing method provided by an embodiment of the present invention is introduced in detail.

[0054] refer to figure 1 , shows a flowchart of a video clipping method in an embodiment of the present invention.

[0055]Step 100, perform scene switching recognition on the pre-edited video, and obtain at least one scene switching picture and at least one scene switching video segment.

[0056] Wherein, the scene switching picture has a corresponding relationship with the scene switching video segment.

[0057] For example, scene switching recognition is performed on a pre-edited video, and 5 scene switching pictures and 5 scene switching video segments are obtained. The 5 scene switching pictures and the 5 scene switching video segments have a one-to-one correspondence: picture a corresponds to video segment A, picture b corresponds to video segment B, picture c corresponds to video segment C, and picture d corresponds to video segment D Correspondingly, picture e...

Embodiment 2

[0066] A video editing method provided by an embodiment of the present invention is introduced in detail.

[0067] refer to figure 2 , shows a flowchart of a video clipping method in an embodiment of the present invention.

[0068] Step 200, perform scene switching recognition on the pre-edited video, and obtain at least one scene switching picture and at least one scene switching video segment.

[0069] Among them, the scene switching recognition is based on the YUV (a color coding method adopted by the European television system) data analysis of the pre-edited video decoding. The scene switching picture has a one-to-one correspondence with the scene switching video segment.

[0070] Preferably, the step 200 may include the following sub-steps:

[0071] In sub-step 2001, scene switching recognition is performed according to the picture color difference of two consecutive video frames of the pre-edited video.

[0072] The pre-edited video is composed of a plurality of co...

Embodiment 3

[0098] A video clipping device provided by an embodiment of the present invention is introduced in detail.

[0099] refer to image 3 , shows a structural diagram of a video clipping device in an embodiment of the present invention.

[0100] The device may include: a scene switching identification module 300 , a picture selection module 302 , a video segment determination module 304 , and a video merging module 306 .

[0101] The functions of each module and the relationship between each module are introduced in detail below.

[0102]The scene switching identification module 300 is configured to perform scene switching identification on the pre-edited video to obtain at least one scene switching picture and at least one scene switching video segment.

[0103] The scene switching picture has a corresponding relationship with the scene switching video segment.

[0104] The picture selection module 302 is configured to select, among the scene switching pictures, a scene switch...

Abstract

The invention provides a video editing method and device. The video editing method comprises the steps that scene switching and identification are carried out on a pre-edited video to obtain at least one scene switching image and at least one scene switching video section, each scene switching image and the corresponding scene switching video section are in a corresponding relation, scene switching images belonging to the same video scene are selected from the scene switching images, the scene switching video sections belonging to the same video scene are determined according to the corresponding relation between each scene switching image and the corresponding scene switching video section and the scene switching images belonging to the same video scene, the determined scene switching video sections belonging to the same video scene are fused to form a video and video editing is completed. By means of the video editing method and device, editors are liberated, an editor can simultaneously edit several videos, the editors do not need to stare at the videos the whole time in the preview process for live broadcast streams, and the working efficiency of video editing is improved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video editing method and device. Background technique [0002] The existing video clipping process judges the clips in the video by means of manual preview. For example, in the process of editing a variety show video, editors judge the program time segment and advertisement time segment by previewing the entire video, and then complete it through video editing software. [0003] This method requires high skills of editors, and the process of previewing the entire video is time-consuming, and the efficiency of video editing is low, especially when editing news clips of live streams, which requires higher effectiveness of editing. [0004] Moreover, the way of manual preview not only requires editors to concentrate, but also an editor can only edit one video at the same time. Contents of the invention [0005] The present invention provides a video editing me...
