Problems solved by technology
[0002] Most of the current architectural media screens are simple video splicing; that is, the existing technology cannot apply video cutting technology well to architectural media screens, so that the videos played on architectural media screens cannot be interactive, and the artistic effect is poor ; The existing video cutting technology, after cutting the video, the boundary and outline of the video are blurred, the video is prone to stuttering, the definition is reduced, and the accuracy of the pixel level is not reached, which will reduce the quality of the video and cannot be applied In the light show of the urban media wall; in addition, the cutting algorithm of the existing technology is too slow, the cutting time is long, the efficiency is low, and the cutting has limitations, and still requires a lot of manual steps

Embodiment Construction
[0024] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] Such as Figure 1 to Figure 3 As shown, this example provides a video cutting method for a city media wall light show, including the following steps:
[0026] Step S1, uploading a video file, and converting the video in the video file into a video in a predefined format;
[0027] Step S2, reviewing the converted format video, and jumping to step S3 for video cutting after the review is passed;
[0028] Step S3, setting the node information for video cutting, cutting the original video according to the node information and the video information of the original video, to obtain the cut video;
[0029] Step S4, previewing and playing the cut video after cutting.
[0030] In the step S1 described in this example, the video format in the video file is converted into the format video of MP4; Preferably, in the described step S...
