Abstract

The invention relates to an intelligent video editing algorithm. The method comprises stes of acquiring camera motion track data, removing jitter time frames through a standard median filtering algorithm; obtaining high quality video pictures, dividing the video picture into a smooth track video and an abnormal track video according to the motion track of the camera; then, carrying out picture score analysis on the video marked as the smooth track; performing depth-of-field analysis again to obtain a small depth-of-field blurring close-up shot if the requirements are met; furthermore, retrieving a smooth trajectory video according to the spatial trajectory data of the camera motion, carrying out curved surface fitting to obtain a high-dynamic close-up lens and pick up the high-dynamic close-up lens, and based on the matrix microphone sound detection system, detecting the audio frequency of a shooting site, picking up and marking a site picture as an immediate performance lens, and thensynthesizing the three lenses into a propaganda video conforming to a preset duration. According to the method, no manual participation exists in the video editing process, video screening and editing can be automatically carried out, an automatic synthesis technology is added, and video editing fragment output is instantly provided.

Description

technical field [0001] The invention relates to the technical field of video shooting and editing, in particular to an intelligent video editing algorithm. Background technique [0002] In film and television shooting, sports or various performances, it is generally necessary to set up multiple cameras to shoot at the same time and record the detailed process of the performance. [0003] Multi-camera shooting enriches the video content and allows the audience to see more display perspectives, but multi-camera shooting will increase the difficulty of post-video processing, requiring a large number of people to manually select and edit films, which is costly, time-consuming, and poor in timeliness . Contents of the invention [0004] Based on this, it is necessary to provide an intelligent video editing algorithm for the current situation of high cost, long time, and poor timeliness of video editing, which can be used for large-scale sports games, performances and sports pr...
