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...

Examples

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...
