Problems solved by technology

On the one hand, in terms of quality, users on the demand side are increasingly looking forward to video content with better expression and more appropriate integration of audio and video, while inexperienced producers often find it difficult to produce satisfactory content; on the other hand, in terms of efficiency In terms of production and cost, limited by factors such as experience and tools, it is difficult for some video content production to meet the needs of the industry. Although the application of professional production can bring efficient production and high-quality video content, it will inevitably bring additional costs. Especially for some types of product object information, such as fashion, consumer electronics, etc., the product object information in the product object information service system is updated more frequently, and the use of video content is also very frequent. This may bring certain costs to the corresponding provider users

Embodiment 1

[0101] First of all, the first embodiment provides a music information processing method. The execution subject of this method can be a "tool" running in a specific application server. There can be many kinds of specific applications. You can use this tool to process the music in the pre-acquired music library, and you have obtained the music collection corresponding to the specific scene, and then use the music in the music collection to recommend the music matching requirements in the corresponding scene to match the sound. Draw highly integrated video content. Specifically, see figure 2 , the method may specifically include:

[0102] S210: Obtain a first music library, the first music library includes at least one reference music that can be matched with the target scene;

[0103] Wherein, the number of music included in the first music library will be relatively small, specifically, it may be typical music matched by a specific music expert or music worker for a specifi...

Embodiment 2

[0127] The second embodiment protects the tool for extracting music features used in the first embodiment, that is, the second embodiment specifically provides a method for extracting music feature information, see image 3 , the method may specifically include:

[0128] S310: Determine the beats per minute BPM information in the target music, and determine the BPM time points included therein;

[0129] S320: Determine the sampling time point according to the BPM time point, and determine the frequency and corresponding intensity information of at least one sound included in each sampling time point;

[0130] During specific implementation, each BPM time point may be determined as a sampling point respectively. Or, it is also possible to determine the number of beats included in each bar in the target music; then, determine the first beat of each bar according to the number of beats included in each bar, and set the first beat of each bar to The corresponding BPM time point ...

Embodiment 3

[0138] The third embodiment mainly introduces the implementation manner of applying the music set corresponding to the scene information generated in the first embodiment above. In this method, a server and a client can be provided for specific applications, wherein the corresponding relationship between specific scene information and music collections can be saved in advance on the server, and the specific music collections can include Multiple pieces of music that match the scene. The client is mainly used to submit a specific video production request to the server, and at the same time, it can also submit information related to the scene to be delivered, such as the category of the associated product object, the type of promotional activity, the content The subject of the board, etc. In this way, the server can recommend music information matching the scene for the user to select and use.

[0139] Specifically, see Figure 4 , the third embodiment provides a music inform...

Abstract

The embodiment of the invention discloses a music information processing and recommending method and device, and the method comprises the steps: obtaining a first music library comprising a pluralityof pieces of reference music, and determining the corresponding relation between scene information and the reference music which can be matched with a scene; obtaining a second music library; performing music feature extraction on music in the first music library and the second music library respectively; determining the similarity between the music in the second music library and the reference music in a feature comparison mode; and according to the similarity, generating a corresponding relationship between the scene information and a music set, so as to recommend music to music matching requirements in the corresponding scene. Through the method of the invention, more convenient and efficient help can be provided for work in the aspects of video content making, auditing and the like ofthe commodity object information.

Description

technical field [0001] The present application relates to the technical field of video content production and processing, in particular to music information processing and recommendation methods and devices. Background technique [0002] Information media is the carrier of information dissemination, and the emergence of new media forms that carry more and more information more conveniently provides great convenience for information dissemination and people's lives. Among them, the video information medium that combines music and images occupies an unshakable position in various forms of information media due to its vivid expressiveness, richness of content, and the impact of multiple senses on the audience. , has a wide range of applications in various fields of social life. For example, in the product object information service system, the user of the product object information provider can publish the product object information. In the process of publishing information, v...
