Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 and figure 2 As shown, a video processing method for sound-driven particle effects, specifically comprising the following steps:

[0025] 101) Step of selecting video and special effects: the user selects the video to be edited and the particle special effect template to be driven.

[0026] 102) audio and video synchronization step: the video selected in step 101) is read out a section of PCM data, namely pulse code modulation data, that is, audio by the Audio decoder, and by performing data segmentation by the time step of the audio time, with This achieves the synchronization of audio and video effects, ensuring the real-time interaction of the effect experience.

[0027] 103) Fast spectrum analysis step based on FFT: analyze the audio information in step 102) by FFT, obtain audio parameters, and cache the analysis...

Abstract

The present invention discloses a video processing method of a sound-driven particle effect. The method specifically comprises the following steps of: video and special effect selection; audio and video synchronization; FFT-based fast spectrum analysis; audio information and particle corresponding; and particle effect generation. With the method of the invention adopted, a whole process is quick and smooth and has high visualization performance.

Description

technical field [0001] The present invention relates to the field of video, and more specifically, it relates to a video processing method for sound-driven particle special effects. Background technique [0002] In recent years, smart phones have become more and more popular, and their functions have become more and more powerful. It is also more and more common to use mobile phones to share the videos you shoot in your daily life. In addition to adding some special effects to the expressiveness of traditional video sharing content, there are few interactive effects with the sound in the video, and the production of special effects is not convenient and intuitive enough. Contents of the invention [0003] The purpose of the present invention is to provide a video processing method for sound-driven particle special effects, which makes the whole process fast and smooth and highly visualized. [0004] In order to solve the problems of the technologies described above, the t...
