Problems solved by technology

[0002] In the prior art, video special effects processing is mostly based on graphics and image processing technology, and a single frame of image itself is processed in real time to generate specific special effects. The special effects generated are usually just repeated effects of a period of time, and the special effects are single and homogeneous, which cannot satisfy users. individual needs

Embodiment Construction

[0035] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0036] ginseng figure 1 As shown, this embodiment provides a method for generating special effects based on music rhythm, including:

[0037] Step S1, extracting pulse code modulation data of a piece of music;

[0038] Step S2, performing mathematical operations on the extracted pulse code modulation data to obtain a numerical value representing the rhythm of the music;

[0039] Step S3, using the numerical value representing the rhythm of the music to drive the special effect.

[0040] In this embodiment, step S2 includes:

[0041] Calculate the root mean square or variance of the pulse code modulation data of the combined audio sample to obtain the effective value of the sample; wherein the combined audio sample is obtained by mixing several samples of multiple channels.

[0042] In this embodiment, before ca...

Abstract

The invention belongs to the technical field of video production, in particular to a method and a device for generating special effects based on musical rhythm, wherein the method comprises the following steps: extracting pulse code modulation data of a piece of music; performing mathematical operation on the extracted pulse code modulation data to obtain a numerical value representing the rhythmof the piece of music; driving special effects with numerical values representing the rhythm of the music. The special effects include, but are not limited to, special effects such as brushes, pictures, vibrations, and the like. The invention introduces an audio dimension on the basis of graphics image processing, so that the special effect of a video can be changed along with the audio rhythm, and the personalized requirements of users are met.

Description

technical field [0001] The invention belongs to the technical field of video production, in particular to a method and device for generating special effects based on music rhythm. Background technique [0002] Most of the video special effects processing in the prior art is based on graphics and image processing technology, and the single frame image itself is processed in real time to generate specific special effects. The special effects generated are usually just repeated effects of a period of time, and the special effects are single and homogeneous, which cannot satisfy users. individual needs. Contents of the invention [0003] The purpose of the present invention is to provide a method and device for generating special effects based on music rhythm, combining special effects with music rhythm changes, so that the results of each special effect are different, and it is a meaningful change, rather than random chaos carried out. [0004] The invention provides a meth...
