Abstract

An embodiment of the invention discloses a method for synthesizing video and audio files. The method comprises the steps of obtaining original media files from a network terminal; analyzing and merging original media files, importing materials in original media files into a time line, and obtaining main editing materials; packaging switched or overlapped portions of main editing materials on the time line into new materials, and obtaining sub-editing materials; conducting sequential merging of main editing materials and sub-editing materials to generate object files; and outputting program files after packaging object files. According to the embodiment, materials on the sequential time line are merged, in-and-out point portions, overlapped portions, special technique portions, subtitle portions and the like of all materials form materials in a uniform format, and materials are output after being packaged, so that rapid merging of media files are guaranteed and the producing efficiency is greatly improved on the condition of no program quality loss.

Description

technical field [0001] The invention relates to the field of digital video and audio industry, in particular to a method for synthesizing video and audio files. Background technique [0002] With the continuous development of today's digital media and the continuous emergence of new media services such as network on-demand, IPTV, VOD, NVOD, mobile video, and handheld TV, the business strategy of new media is also based on purchasing and integrating a complete set of programs or low-cost deep processing. , taking into account high efficiency. Most of the program material sources are finished streaming programs. For these streaming media, a fast editing software is urgently needed, which can quickly remove the beginning and end, edit out interstitial advertisements, banned screens and other unnecessary content; or quickly combine the same attribute files The footage can be quickly spliced ​​into a new program stream file without loss of quality, and released to the content in...
