The distribution rule configuration page is used for configuring distribution rules for part of target videos in the target video set, and the distribution rules configured by the distribution rule configuration page are specific to one or a few target videos. In this case, different target videos may be published using different publication rules, or may be published using the same publication rules.
The release rule configuration options refer to options with a video generation function, and after triggering, release rule configuration pages of the target video are displayed, wherein the release rule configuration options can be controls, menu items or specific texts.
The selection operation of the distribution rule configuration option may be, for example, a click or slide operation of the distribution rule configuration option or the like.
In some embodiments, if the distribution rule configuration page is used to configure the distribution rule for the target video set, the target page may be set to further include summary information of the target video set, where a display position of the distribution rule configuration option of the target video is adjacent to a display position of the summary information of the target video set.
The target video set may have a plurality of attributes after being generated, for example, if the video is created for the purpose of commodity promotion, the attributes of the target video set include, for example, a generation time, a task name, a target video content, a name of a commodity promoted, a name of a merchant selling the commodity promoted, and the like. Summary information of a target video set may be, for example, a set of partial attributes of the target video set.
The display position of the release rule configuration options is adjacent to the display position of the summary information of the target video set, for example, the target page may include a plurality of sub-display areas arranged vertically or horizontally, and the release rule configuration options and the summary information corresponding to the same target object set are located in the same sub-display area.
For example, referring to fig. 2, in the target page, a plurality of sub-presentation areas are arranged vertically, and distribution rule configuration options corresponding to the same target object set and summary information of the target video are arranged horizontally to occupy the same line.
In practice, when the video generating method provided in the present application is performed multiple times, it can be regarded that a plurality of video generating tasks are performed, and a plurality of target video sets will be obtained. Because each target object set is provided with the corresponding release rule configuration options, a plurality of release rule configuration options are required to be displayed in the target page, and the user can understand which target video set each release rule configuration option corresponds to by means of the abstract information of the target video set by setting the display position of the release rule configuration option of the same target video set adjacent to the display position of the abstract information.
Illustratively, suppose that the video generation method provided herein was previously performed 4 times in total, see fig. 2, the target page includes summary information of four target video sets and four distribution rule configuration options. In fig. 2, each row represents a target video set. The user can know which target video set each row represents through the summary information in each row. If the user selects the publishing rule configuration option in the first row, see fig. 5, a publishing rule configuration page of the target video set represented by the first row is presented. The distribution rule configuration page includes a plurality of configuration items such as an account number for distributing a target video, POI (address of a store selling a commodity advertised by the target video) setting, distribution mode, and distribution period. When the user configures each configuration item in the release rule configuration page and selects a release option, the release rule defined by the configuration content of each configuration item together releases the target videos in the target video set.
In practice, all video materials in the video material library may be required in the process of generating the target video, or only part of the video materials in the video material library may be used.
Those skilled in the art will appreciate that in practice, the same video material, if applied to make multiple target videos, can be tiring for a user viewing the target videos. In this regard, optionally, each time a video material is used in generating the target video, the video material is marked. The purpose of marking the video material is to indicate that the video material has been applied to generate a target video. On the basis, optionally, if the material consumption proportion of the video material library is greater than or equal to a set threshold value, displaying prompt information for prompting the supplementary video material; the material consumption ratio is the ratio of the number of video materials that have been applied to generate the target video to the total number of video materials in the video material library.
If the material consumption ratio of the video material library is greater than or equal to the set threshold, the number of video materials which are not applied to generating the target video in the video material library is small, and the video materials need to be timely supplemented so as to ensure that the target video can be generated based on the video materials in the video material library.
In the above technical solution, the specific implementation method of S130 is various, which is not limited in this application. Illustratively, the specific implementation method of S130 includes: creating target video according to video creation destination information input in the information collection page; and displaying a video preview page, wherein the video preview page comprises target videos in a target video set.
Further, there are various specific implementation methods for generating the target video, which are not limited in this application. Illustratively, referring to fig. 6, generating the target video includes:
s210, determining a video script based on the video creation destination information.
The video script may be, for example, a planning scheme for the target video, which defines that several shots are required for generating the target video, the content or expressed emotion to be exhibited by each shot, and the like.
Optionally, the video script includes a plurality of shot scripts, and the shot scripts are planning schemes for one shot. Illustratively, one shot script includes at least one of a shot name, a document, screen information, and highlight information. The document is information describing the contents of the shots. The screen information is information describing features of the shot content. The highlight information is information that is desired to be presented in a highlighted form in the shot. Further, it may also be set that the screen information includes at least one of a scene, a subject, and a style. The scene refers to a background environment in a picture, the main object refers to a person, an animal or an object which takes the dominant role in the picture, and the main object is a core object for showing the lens. Style refers to the overall visual effect of a picture. The style may convey the emotional mood of the picture, such as happy, sad, serious, or relaxed, etc.
A target video is formed by arranging a plurality of shots in a certain order. Accordingly, in one video script, a plurality of shot scripts are arranged in a certain order.
There are various ways to implement this step, and this application is not limited thereto. In one embodiment, the implementation method of the step includes: extracting keywords from the video creation destination information to obtain target keywords; and determining the video script corresponding to the target keyword in the video script library.
Illustratively, assume that the video creation purpose is to advertise a certain merchandise. And extracting keywords from the video creation destination information, wherein the obtained target keywords are commodity propagandas, and searching video scripts for carrying out commodity propaganda in a video script library.
In practice, the video creation purposes are various, and even if the video creation purposes are all used for advertising goods, angles and modes of different goods are slightly different. This makes it possible that the method for generating the video script of the target video determined by the method for querying the video script library may occur that the determined video script is not well suited for promoting the merchandise that the user wishes to promote, eventually resulting in a failure to achieve the video creation purpose well.
In another embodiment, the implementation method of this step includes: and inputting the video creation destination information into a video script generation model to obtain a video script corresponding to the video creation destination. The video script generation model is a neural network model taking video creation destination description information as input information and taking video script as output information. The "video script generation model" mentioned in this paragraph is a trained neural network model. By the arrangement, the determined video script can be well adapted to the video creation purpose.
In practice, a good quality sample video including multiple shots may be selected to train the video script generation model. The specific training process can comprise the following steps: obtaining a sample video; converting the sample video into a sample video script and creating target information of the sample video; the video script generation model is trained based on the sample video script and sample video creation destination information.
Further, the method further comprises: acquiring play data of the released target video; and adjusting the video script generation model according to the play data.
The play data may be, for example, an indicator reflecting the quality and popularity of the target video. Illustratively, the play data includes at least one of: the completion rate, the praise number, the comment number and the play amount. The playback completion rate may be, for example, a ratio of the number of times the target video is viewed to the number of times the target video is played.
"adjusting the video script generation model according to the play data" means optimizing the video script generation model so that it can output a higher quality video script. The better the video script, the better the quality of the generated target video, and the higher its popularity.
The evaluation criteria for the high-quality video script are various. Such as high video playback rates or high popularity.
Illustratively, the preset shot script includes: the method comprises the steps of dividing a scene into a plurality of parts, and dividing the scene into a plurality of parts, wherein the part comprises a division name, a text, picture information and highlight information, and the picture information comprises a scene, a main body object and a style. Optionally, an auxiliary rule may be further set, such as that the screen information does not include a shop name, the highlight information needs to select text that can attract a video viewer when determining, the word count limit condition of the text, and the style in the text and the screen information is determined according to the promotion degree.
In one example, if the video creation destination information includes: the store is described as a newly opened XX coffee shop, is positioned beside a YY subway station, has a core selling point of low price and good environment, and has the trade name of osmanthus latte which only needs zz yuan and has low propaganda degree. Wherein XX represents a coffee shop name, YY represents a subway station name, and zz represents the price of the osmanthus latte. After the video creation destination information is input into a video script generation model, the obtained video script comprises 3 shot scripts. Specifically, the video script is as follows.
