[0042] Figure 1 is a schematic flowchart of a video generation method provided in an embodiment of this disclosure. This embodiment is applicable to situations where a video of a target object is generated when there is limited source material, such as generating a product promotion video or product marketing video based on limited source material. The method can be executed by a video generation device, which can be implemented in software and / or hardware, optionally through an electronic device, such as a mobile terminal, PC, or server.

[0043] As shown in Figure 1, the method includes:

[0044] S110. Display the target material area on the video generation page. The target material area is used to display the media material set associated with the target video of the target object.

[0045] The video generation page is an interactive page representing the video generation service. The video generation service generates promotional or marketing videos for a target object. The target object can be an object to be promoted, such as a product or commodity. The target material area is a control on the video generation page used to display a set of media materials. In this embodiment, the media material set includes the original materials corresponding to the target object. The original materials include locally uploaded images and / or videos. The original materials also include images and / or videos obtained by parsing the webpage associated with the target object. The media material set may also include target recommended materials, which represent selected candidate recommended materials.

[0046] For example, the original materials of the target object can be obtained by uploading images and / or videos associated with the target object, and then loaded into the target material area. Alternatively, the original materials of the target object can be obtained by parsing the details page corresponding to the target object, and then loaded into the target material area.

[0047] Specifically, the process involves retrieving the webpage associated with the target object, parsing the webpage to obtain images and / or videos of the target object, and further parsing the webpage to obtain object information and / or the name of the target object. The images and / or videos of the target object are then displayed in the target material area of ​​the video generation page.

[0048] S120. Display a material recommendation area on the video generation page, and display candidate recommended materials in the material recommendation area.

[0049] The "Material Recommendation Trigger Operation" is used to trigger a material recommendation event. This event queries a pre-defined material set based on at least two screen descriptions corresponding to the object information of the target object to obtain candidate recommended materials. For example, the material recommendation trigger operation might include inputting the URL of the target object. Alternatively, it might include inputting the object information of the target object. Or, it might include inputting the name of the target object, and using a pre-trained text generation model to generate the object information based on that name.

[0050] Optionally, a material recommendation event can also be triggered based on the original materials in the target material area. For example, if the number of original materials in the target material area does not meet a preset quantity requirement, a material recommendation event is triggered. And / or, if the attribute information of the original materials in the target material area does not meet preset attribute requirements, a material recommendation event is triggered. Attribute information includes attributes that affect material quality, such as resolution.

[0051] The candidate recommended materials are obtained by querying a preset material set based on at least two scene descriptions corresponding to the object information of the target object. The scene descriptions are generated based on the object information of the target object and prompt words. For example, the scene description could be a dog running in the sunlight. At least two scene descriptions are generated based on the object information and prompt words using a preset generation model. The prompt words constrain the generation results of the preset generation model. Based on each scene description, a preset material set is queried to obtain candidate recommended materials whose matching degree with the scene description exceeds a set threshold.

[0052] For example, in response to a material recommendation trigger operation on the video generation page, a first form of the material recommendation area is displayed, wherein the first form of the material recommendation area includes a placeholder image of recommended materials. If the candidate recommended materials are successfully loaded, a second form of the material recommendation area is displayed, wherein the placeholder image of recommended materials in the second form of the material recommendation area is replaced with the candidate recommended materials. The second form of the material recommendation area includes at least two material groups associated with different screen description information, and adjacent material groups are associated with different screen description information. Each material group includes at least two candidate recommended materials.

[0053] The recommended material placeholder image serves as a placeholder for candidate recommended materials within the material recommendation area. This placeholder image includes a recommendation identifier to distinguish it from the original materials in the target material area. In response to a material recommendation trigger on the video generation page, the first form of the material recommendation area and a loading prompt text can be displayed. At this stage, the material recommendation area includes the recommended material placeholder image. If the candidate recommended materials load successfully, the second form of the material recommendation area is displayed, showing the candidate recommended materials in the positions corresponding to the recommended material placeholder image, and the loading prompt text changes to a loading completion text. Optionally, the material recommendation area can also display prompts such as the number of selected materials and the total number of available materials. The candidate recommended materials displayed in the material recommendation area can be switched using a swipe gesture.

[0054] In this embodiment, the material recommendation area includes at least two material groups associated with screen description information, and adjacent material groups are associated with different screen description information. Each material group includes at least two candidate recommended materials. By sorting the candidate recommended materials in descending order according to their matching degree along the screen description information dimension, and grouping the candidate recommended materials according to the sorting result, material groups containing at least two candidate recommended materials are obtained. The material groups associated with each screen description information are then displayed sequentially according to the order of the screen description information. This grouping and dispersing of candidate recommended materials allows for the display of multiple candidate recommended materials associated with different screen description information within the material recommendation area, improving the richness of material selection. Furthermore, it avoids users spending excessive time discovering candidate recommended materials associated with screen description information that match their expectations, thus improving material selection efficiency.

[0055] In this embodiment of the disclosure, the material recommendation area represents the control for displaying candidate recommended materials on the video generation page. In response to a material recommendation trigger operation on the video generation page, a material recommendation area in a loading state is displayed on the video generation page. For the material recommendation area in a loading state, multiple placeholder images of recommended materials are displayed, each including a set recommendation identifier. If the candidate recommended materials are successfully loaded, the material recommendation area in a loading state is switched to a material recommendation area in a loaded state, and the candidate recommended materials are displayed at the corresponding positions of the placeholder icons in the material recommendation area. Figure 2 is a schematic diagram of the structure of a video generation page provided in this embodiment of the disclosure. As shown in Figure 2, the target material area 210 displays original materials and placeholder images of recommended materials. The target material area 210 includes target recommended materials (with a seven-pointed star symbol) and original materials (without a seven-pointed star symbol). The candidate recommended materials in the material recommendation area 220 are displayed in the following order:

[0056] The candidate recommended materials associated with screen description information 1 are A11 and A12; the candidate recommended materials associated with screen description information 2 are B11 and B12; the candidate recommended materials associated with screen description information 3 are C11 and C12; the candidate recommended materials associated with screen description information 1 are A13 and A14; the candidate recommended materials associated with screen description information 2 are B13 and B14; the candidate recommended materials associated with screen description information 3 are C13 and C14; ...; the candidate recommended materials associated with screen description information 1 are A1n and A1n; the candidate recommended materials associated with screen description information 2 are B1n and B1n; the candidate recommended materials associated with screen description information 3 are C1n and C1n. The value of n is determined based on the maximum number of loadable materials in the material recommendation area 220. Because users' creative needs vary greatly, different users may have significantly different choices of candidate recommended materials, making it difficult to predict the user's choice of candidate recommended materials in advance. By prioritizing the display of the two candidate recommended materials with the highest matching degree among the three screen description information associations, users can more easily select candidate recommended materials that match their expected screen description information, thereby improving material selection efficiency and optimizing user experience.

[0057] Optionally, in response to a material recommendation trigger operation on the video generation page, at least one placeholder image of the recommended material is displayed in the target material area. If the candidate recommended material is successfully loaded, candidate recommended materials that meet preset filtering conditions are displayed at the positions corresponding to the placeholder images of the recommended materials in the target material area. The preset filtering conditions are determined by combining the order of the material group and the order of the candidate recommended materials within the material group.

[0058] Since the candidate recommended clips within a clip group are sorted by matching degree, the first candidate recommended clip in the group has a higher matching degree than the remaining candidate recommended clips in the group. A preset filtering condition could be to select the first candidate recommended clip in the target clip group and add it to the target clip area, thus prioritizing the recommendation of the most matching candidate recommended clips in the target clip group for generating the target video. Due to the limited number of clips that can be loaded into the target clip area, N clip groups can be selected as the target clip groups according to the order of the image description information.

[0059] Optionally, in response to a click operation on the delete control corresponding to a target recommended material in the target material area, the deleted target recommended material is restored from the target material area to the corresponding material group in the material recommendation area, thereby replacing the target recommended material in the target material area. For example, after adding candidate recommended material B11 to the target material area, if a deletion operation is detected for candidate recommended material B11, candidate recommended material B11 can be moved to the display position of the material group associated with screen description information 2, and displayed before candidate recommended material B12.

[0060] Optionally, if the duration of all video materials in the target material area is less than a set threshold after deleting the target recommended material in the target material area, a prompt message will be displayed indicating that candidate recommended materials of at least the set duration will be loaded, in order to guide the user to continue selecting target recommended materials.

[0061] In some embodiments, if the candidate recommended materials fail to load, the first-form material recommendation area on the video generation page is deleted, and the recommended material placeholder image in the target material area is deleted. Specifically, if no candidate recommended materials associated with the image description information are matched, it is determined that the candidate recommended materials have failed to load. Deleting the first-form material recommendation area on the video generation page and deleting the recommended material placeholder image in the target material area allows the target video to be generated based on the original materials in the target material area. In the case of candidate recommended material loading failure, this embodiment deletes the recommended material recommendation area and the recommended material placeholder image in the target material area, and generates the target video using the original materials, which can avoid the problem of blocking subsequent video generation operations due to candidate recommended material loading failure.

[0062] It should be noted that the recommended content area will not be displayed if the information on the video generation page does not belong to any target object. However, if any of the following actions are detected on the video generation page: inputting the product name, object information, or original footage of the target object, a recommended content area will be displayed on the video generation page.

[0063] In some embodiments, in response to the input of an object name on the video generation page, a first form of the material recommendation area is displayed. A preset generation model predicts the target object based on the object name association, determines the scene description information based on the predicted object information, and then determines a recommended material list based on the scene description information. The recommended material list includes candidate recommended materials, which are determined based on the matching degree and the number of scene description information. For example, if there are 6 scene description information, the top five candidate recommended materials with the highest matching degree for each scene description information constitute a recommended material list containing 30 candidate recommended materials. The recommended material list is loaded onto the video generation page. If the candidate recommended materials are loaded successfully, the candidate recommended materials in the recommended material list are displayed in the material recommendation area.

[0064] Furthermore, after displaying candidate recommended materials from the recommended material list in the material recommendation area, if an input operation on object information is detected on the video generation page, new scene description information is determined based on the object information, and candidate recommended materials are determined based on the new scene description information. The recommended material list is updated based on the newly determined candidate recommended materials. If the recommended material list before and after the update is different, the material recommendation area is reloaded.

[0065] Furthermore, in response to updates to object names and / or object information, the screen description information is updated. Candidate recommended materials are determined based on the updated screen description information. The recommended material list is updated based on the newly determined candidate recommended materials. If the recommended material lists before and after the update differ, the recommended material area is reloaded.

[0066] S130. In response to the material selection operation for the candidate recommended material, the target recommended material is transferred from the material recommendation area to the target material area to add the target recommended material to the media material set.

[0067] The media selection operation is used to trigger a media selection event. This event moves the target recommended media from the media recommendation area to the target media area, adding it to the media media set. For example, clicking the media add control corresponding to a candidate recommended media triggers the media selection event. Alternatively, selecting candidate recommended media triggers the event. Or, dragging candidate recommended media triggers the event. This disclosure does not specifically limit the meaning of the media selection operation.

[0068] Optionally, the candidate recommended materials can be previewed before selecting the target recommended material. For example, the duration of the material is displayed at a designated position within the candidate recommended material. In response to a click operation on the duration of any candidate recommended material, a preview page corresponding to the candidate recommended material is displayed, and the candidate recommended material is played on the preview page.

[0069] Figure 3 is a schematic diagram of another video generation page structure provided in this embodiment. As shown in Figure 3, the material recommendation area displays candidate recommended materials 310 associated with different scene descriptions. The lower left corner of the candidate recommended material 310 displays the material duration. The upper right corner of the candidate recommended material 310 displays a material addition control 320. Clicking on the material duration displays a preview page 330 in the form of a pop-up window on the video generation page. The candidate recommended material 310 is played on the preview page 330 so that the user can select the candidate recommended material 310 that meets their expectations.

[0070] For candidate recommended materials that meet the expectations, a target recommended material can be determined through a material selection operation, and then transferred from the material recommendation area to the target material area. For example, in response to a click operation that adds a control to the material corresponding to the candidate recommended material, the target recommended material is transferred along a preset movement path to a set material display position in the target material area. Here, the target recommended material represents the candidate recommended material associated with the click operation, and the preset movement path represents the line segment between the position of the target recommended material in the material recommendation area and the set material display position. The target recommended material is then displayed at the set material display position. Optionally, the set display position can be the position in front of existing materials in the target material area. For example, each time a target recommended material is added to the target material area, it is added before all materials in the target material area to display the target recommended material at the head of the target material area. By transferring the target recommended material along a preset movement path, the transfer process of the target recommended material can be presented, improving the interactivity of the candidate recommended materials.

[0071] Furthermore, in response to a click operation on the control added to the material corresponding to the candidate recommended material, the target recommended material is moved along a preset movement path to a set material display position in the target material area, including:

[0072] In response to a click operation on the control for adding the material displayed at a set position of the candidate recommended material, the target recommended material is moved along the preset movement path. During the movement of the target recommended material along a first path segment of the preset movement path, the target recommended material is transformed from a first form to a second form, wherein the first path segment represents a line segment between the position of the target recommended material in the material recommendation area and the target position on the video generation page. During the movement of the target recommended material along a second path segment of the preset movement path, the target recommended material is restored from the second form to the first form, wherein the second path segment represents a line segment between the target position and the set material display position.

[0073] In this embodiment of the disclosure, the thumbnail representing the target recommended material in the first form is gradually reduced in size from its original size. The thumbnail representing the target recommended material in the second form is gradually enlarged back to its original size after being reduced in size.

[0074] Figure 4 is a schematic diagram of another video generation page provided in this embodiment. As shown in Figure 4, a material addition control 420 is displayed in the upper right corner of the candidate recommended material 410. Based on the click operation of the material addition control 420, the target recommended material is moved along a preset movement path 430. The preset movement path includes a preset target position 431. The line segment between the position of the target recommended material and the target position is taken as the first path segment 432. The segment between the target position and the set material display position in the target material area is taken as the second path segment 433. During the movement of the target recommended material along the first path segment 432, the thumbnail of the target recommended material is gradually reduced. The distances of points A, B, and C on the first path segment 432 from the starting point of the path increase sequentially, and the size of the corresponding target recommended material thumbnail decreases sequentially. During the movement of the target recommended material along the second path segment 433, the reduced thumbnail of the target recommended material is gradually enlarged until the target recommended material moves to the set material display position in the target material area, and the thumbnail returns to its original size. On the second path segment 433, the distances between points D and E and the path endpoint decrease sequentially, while the sizes of the thumbnails of the corresponding target recommended materials increase sequentially.

[0075] S140. In response to the video generation trigger operation on the video generation page, generate the target video of the target object based on the original materials and target recommended materials in the media material set, and display the target video.

[0076] The video generation triggering operation is used to trigger a video generation event. The video generation event is used to generate a target video of the target object based on a media material set associated with the target material area. Optionally, the target video is generated by combining original materials and target recommended materials within the media material set using a pre-trained generation model. The pre-trained generation model can be a video generation model based on deep learning technology. Optionally, before inputting the original materials and target recommended materials into the preset generation model, image preprocessing and image-text matching operations can be performed to establish a correspondence between images and text.

[0077] This embodiment of the disclosure displays a material recommendation area in response to a material recommendation trigger operation on the video generation page. This area includes candidate recommended materials for creators to select target recommended materials from. The target recommended material is then transferred from the material recommendation area to the target material area, adding it to the media material set associated with the target material area. Finally, the original materials in the media material set and the target recommended material are combined to generate a target video of the target object, which is then displayed. Since the candidate recommended materials are obtained by querying a preset material set based on at least two screen descriptions corresponding to the object information of the target object, the candidate recommended materials have a close correlation with the target object. Adding the target recommended material from the candidate recommended materials to the media material set generates a rich target video based on the media material set, reducing material duplication in the target video, increasing the richness of the target material, and improving the video effect.

[0078] Figure 5 is a flowchart illustrating another video generation method provided in this embodiment. This embodiment, based on the above embodiments, adds a method for querying candidate recommended materials. As shown in Figure 5, the method includes:

[0079] S500. Display the target material area on the video generation page. The target material area is used to display the media material set associated with the target video of the target object, wherein the media material set includes the original material corresponding to the target object.

[0080] S510. Display a material recommendation area on the video generation page, the material recommendation area including a placeholder image of recommended materials.

[0081] S520. Obtain at least one object information associated with the target object, and generate at least two screen description information associated with the object information based on at least one object information and prompt words using a preset generation model.

[0082] The prompt words are used to constrain the generation results of the preset generation model. The prompt words can be set according to business needs.

[0083] Optionally, the video generation page includes an input box control where object information can be entered. Alternatively, the target object's webpage can be obtained; for example, the target object's details page. The webpage content is parsed to obtain images and / or videos from the target object's webpage, which serve as raw materials. Furthermore, parsing the webpage can also obtain at least one of the target object's description information, selling point information, and name information. The object description information can be split into N segments of object information. Then, based on prompts, a preset generation model generates at least two screen descriptions for each segment of object information, resulting in 2N screen descriptions.

[0084] S530. Perform vector matching between the image description vector corresponding to the image description information and the material vector associated with the preset material set to obtain the matching material and the matching degree corresponding to the matching material.

[0085] The preset material set is a collection of images and / or videos. It includes a large number of high-quality materials. The image description vector is a vector obtained by vectorizing image description information. The material vector is a vector obtained by vectorizing multimodal information such as images, videos, and text in the preset material set. Optionally, the image description vector corresponding to the image description information is generated through an embedding model. Furthermore, the material vector corresponding to the materials in the preset material set is generated through the embedding model.

[0086] For example, for any image description information, the vector distance between the image description vector corresponding to the image description information and the vector of the material corresponding to the material in the preset material set is calculated. The matching degree between the material in the preset material set and the image description information is determined based on the vector distance. Material in the preset material set whose matching degree exceeds a set threshold is determined as matched material. The matching degree corresponding to the material in the preset material set whose matching degree exceeds the set threshold is determined as the matching degree corresponding to the matched material.

[0087] Optionally, determining matching materials based on a matching degree exceeding a set threshold in the preset material set further includes: determining matching materials based on the recall priority and matching degree of materials in the preset material set. Specifically, video materials have a higher recall priority than image materials. Vertical video materials have a higher recall priority than horizontal video materials. Video materials of different durations have different recall priorities. For materials in the preset material set with a matching degree exceeding the set threshold, matching materials are determined based on the recall priority, and materials with a matching degree exceeding the set threshold are cached. If the matching materials cannot meet the video generation requirements, the cached materials are added to the material recommendation list.

[0088] S540. Determine the candidate recommended materials among the matched materials based on the matching degree.

[0089] For example, for any scene description information, the matching materials associated with the scene description information are sorted in descending order according to their matching degree. Candidate recommended materials corresponding to each scene description information are determined based on the sorting results. For instance, for each scene description information, the matching materials are sorted in descending order based on their matching degree, and the top n matching materials are selected as candidate recommended materials. A list of recommended materials is generated based on the candidate recommended materials.

[0090] S550. For any one of the screen description information, the candidate recommended materials associated with the screen description information are grouped according to the matching degree to obtain the material group associated with the screen description information.

[0091] For example, for any given image description information, the candidate recommended materials associated with the image description information are grouped according to the matching degree and a grouping strategy to obtain a material group associated with the image description information. The grouping strategy is used to characterize the number of candidate recommended materials within a material group. For example, the candidate recommended materials are grouped according to the descending order of the candidate recommended materials and the number of candidate recommended materials within the material group.

[0092] S560. Based on the order of the screen description information, the material groups associated with the screen description information are displayed sequentially in the material recommendation area.

[0093] For example, following the order of the image description information, the placeholder images in the material recommendation area are replaced with candidate recommended materials from the material groups, so that the material groups associated with each image description information are displayed sequentially in the material recommendation area. Optionally, the display priority of a material group can be determined based on the matching degree of the candidate recommended materials associated with that material group. The undisplayed material group with the highest display priority corresponding to the image description information is displayed at the position corresponding to that image description information in the material recommendation area.

[0094] S570. In response to the material selection operation for the candidate recommended material, the target recommended material is transferred from the material recommendation area to the target material area to add the target recommended material to the media material set.

[0095] S580. In response to the video generation trigger operation on the video generation page, generate a target video of the target object based on the original materials and target recommended materials in the media material set, and display the target video, wherein the video generation trigger operation is used to trigger a video generation event.

[0096] In this embodiment of the disclosure, in response to the video generation trigger operation on the video generation page, a target video of the target object is generated based on the original materials and target recommended materials in the media material set associated with the target material area, and the target video is displayed.

[0097] Optionally, in response to a video generation trigger operation on the video generation page, if the media material set associated with the target material area only contains the target recommended material, then at least one video material in the target recommended material is replaced with a video material from the parsed original material. If the original material is an image material, then the image material in the target recommended material is replaced with the image material.

[0098] In some embodiments, if the duration of the landscape video footage in the media footage set associated with the target footage area meets the preset split-screen conditions, then the target video is a split-screen video. Split-screen mode refers to a video display mode that combines at least two landscape video footage.

[0099] Figure 6 is a flowchart of a video generation method provided in an embodiment of this disclosure. As shown in Figure 6, the method includes: obtaining a webpage 610 of a target object; obtaining images and / or videos associated with the target object from the webpage 610 as raw material 620. Optionally, the raw material 620 may also be images and / or videos uploaded by a user. In addition, the webpage 610 may also obtain object description information, selling point information, and name information of the target object. The user inputs business information and marketing target. A script copy 600 is generated based on the object description information, selling point information, name information, business information, and marketing target. The script copy 6100 is segmented. The object description information can be split into N segments of object information 630. Then, based on prompt words, a preset generation model is used to generate at least two screen description information 640 for each segment of object information 630, resulting in 2N screen description information 640. For example, for object information that is curved and curled and has good waterproof properties, the two generated screen description information 640 may be: Screen 1: A person with long eyelashes blinking; Screen 2: A close-up of washing a face. Based on the image description information 640 and the preset material set 650, a material retrieval 660 is performed. A recommended material list 670 is generated based on the retrieved candidate recommended materials for user selection. Based on the selection operation of the candidate recommended materials, the target recommended material 680 is determined. Preprocessing 690, such as material understanding, is performed on the target recommended material 680 and the original material 620. The preprocessed material is then matched with the segmented script using image-text matching 6100. Based on the image-text matching results and the script text 600, the target video is generated.

[0100] This embodiment of the disclosure matches the image description vector with the material vectors associated with a preset material set to obtain matching materials with a matching degree exceeding a set threshold. The matching materials are then sorted in descending order based on the matching degree to obtain candidate recommended materials, achieving rapid and accurate acquisition of candidate recommended objects associated with the target object. The candidate recommended materials associated with the image description information are grouped according to the matching degree to obtain material groups associated with the image description information. Then, according to the order of the image description information, the material groups of each image description information are displayed alternately, making it easier for users to select candidate recommended materials associated with image description information that meet their expectations, improving material selection efficiency and optimizing user experience.
