[0047] Those skilled in the art know that the embodiments of the present application can be implemented as a device, apparatus, method or computer program product. Therefore, the present application can be specifically implemented in the following forms, namely: complete hardware, complete software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

[0048] According to an embodiment of the present application, a video generating method, a video generating device, an electronic device and a computer-readable storage medium are proposed.

[0049] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0050] The principles and spirit of the present application are explained in detail below with reference to several representative implementations of the present application. SUMMARY OF THE INVENTION

[0052] At present, the existing technology for generating target videos usually involves: manually editing or splicing video materials using video software, or randomly selecting video clips from a video material library, shuffling their order and then splicing them to generate the target video. However, no matter which of the above schemes is adopted, the editor is required to have certain editing skills, and in the second scheme, due to the high randomness, the generated target video may have logical problems and the quality is difficult to guarantee. Therefore, the above schemes will consume a lot of manpower and brainpower in the process of generating the target video, and at the same time, the accuracy of the logic of the generated target video cannot be guaranteed, thereby increasing the complexity of generating the target video and reducing the efficiency of generating the target video.

[0053] Based on the above problems, the applicant has thought of specifying the splicing order in the process of generating the target video. By presetting multiple video groups, multiple video groups store video materials with similar video features, and determine the splicing order between multiple video groups, so that in the subsequent process of generating the target video, the video materials to be spliced ​​can be randomly determined from the multiple video groups, and the video materials to be spliced ​​are spliced ​​according to the splicing order, which not only improves the efficiency of the target video, but also ensures the accuracy of the narrative logic displayed by the generated target video, and can also achieve mass generation of target videos.

[0054] Application Scenario Overview

[0055] It should be noted that the following application scenarios are only shown to facilitate understanding of the spirit and principle of the present application, and the implementation of the present application is not limited in this respect. On the contrary, the implementation of the present application can be applied to any applicable scenario.

[0056] When applied to the scenario of product introduction, it can avoid the inaccuracy of the product introduction logic displayed in the target video, improve the efficiency of generating product introduction videos, and generate introduction videos of related products in large quantities.

[0057] Exemplary Methods

[0058] In combination with the above application scenarios, refer to Figure 1 and Figure 7 A video generation method according to an exemplary embodiment of the present application is described.

[0059] See also Figure 1 , Figure 1 FIG. 2 is a flow chart of a video generation method according to an example implementation of the present application. Figure 1 As shown, the video generation method may include:

[0060] Step S110: determining a plurality of preset video groups, and determining a splicing order between the plurality of video groups and video materials respectively associated with the plurality of video groups; wherein the video materials in the same video group have similar video features.

[0061] Step S120: respectively determining the video materials to be spliced ​​from the video materials respectively associated with the plurality of video groups, and splicing the plurality of video materials to be spliced ​​in a splicing order to obtain a target video.

[0062] Implementation Figure 1 The video generation method shown can preset multiple video groups, and there is a preset splicing order between the multiple video groups, and video materials with similar video features are associated in the multiple video groups. Based on this, the target video can be obtained by splicing the multiple video materials to be spliced ​​in the multiple video groups according to the splicing order. Compared with the prior art, the implementation of the embodiment of the present application does not require the disassembly of different video materials, and does not require the manual editing of multiple video materials. A large number of target videos can be obtained by splicing the video materials to be spliced ​​in the multiple video groups through mixed editing, which reduces the complexity of generating the target video and improves the efficiency of generating the target video.

[0063] These steps are described in detail below.

[0064] In step S110, a plurality of preset video groups are determined, and a splicing order between the plurality of video groups and video materials respectively associated with the plurality of video groups are determined; wherein the video materials in the same video group have similar video features.

[0065] Specifically, the preset multiple video groups are preset according to the final generation requirements of the target video. For example, for product A, the final generated target video needs to include the unpacking of the outer packaging of product A, the unpacking of the inner packaging of product A, the ingredient list of product A, and the close-up shot of product A. Based on this, five video groups need to be preset, namely, video group 1-1 corresponding to the unpacking of the outer packaging of product A, video group 1-2 corresponding to the unpacking of the inner packaging of product A, video group 1-3 corresponding to the ingredient list of product A, video group 1-4 corresponding to the close-up shot 1 of product A, and video group 1-5 corresponding to the close-up shot 2 of product A.

[0066] After determining the preset multiple video groups, the splicing order between the multiple video groups can be determined, and the video materials respectively associated with the video groups can be determined. Specifically, Figure 2 The following schematic diagram shows an interface diagram for generating a target video in the embodiment of the present invention. Figure 2 As shown, including the generated video group 1-1, video group 1-2, video group 1-3, video group 1-4 and video group 1-5. By adjusting the arrangement order of video group 1-1, video group 1-2, video group 1-3, video group 1-4 and video group 1-5, the splicing order between multiple video groups can be determined. When video group 1-3 is touched, the following will be displayed Figure 3 The video material selection interface shown.

[0067] Figure 3 The video material selection interface in the embodiment of the present disclosure is schematically shown. Figure 3 As shown, the touch control 310 can select the corresponding video group, for example, select video group 230 at this time. After selecting video group 230, you can select the video material corresponding to the video group in the video material library, for example, select the video material for displaying the material table of commodity A. The selected video material will be displayed in the interface 320 and associated with the video group 230. Subsequently, if you need to continue to associate the video material corresponding to the video group 230, you can add a video control through the touch control 330. It is worth noting that for a video group, the video materials associated with it have similar video features. For example, the video materials associated with video group 230 all describe the material table of commodity A.

[0068] As an optional embodiment, multiple preset video groups are determined, and video materials respectively associated with the multiple video groups are determined, including: responding to a video group adding operation, generating a video group corresponding to the video group adding operation; responding to a material association operation for a target video group, selecting video materials to be associated from the original video materials, and determining the video materials to be associated as video materials associated with the target video group.

[0069] Among them, Figure 2 As shown, Figure 2 There is a control called Add Video Group in the , and when a touch operation is performed on the control (that is, when a video adding operation is performed), a video group will be generated.

[0070] After generating a video group, you can touch the video group (i.e., perform material association operations on the target video group) to select one or more video materials to be associated that correspond to the video group from the original video material (i.e., the video material library). At this time, the video materials to be associated have an association relationship with the corresponding target video group.

[0071] It can be seen that by implementing this optional embodiment, a video group that meets the target video splicing requirements can be preset, and the corresponding video materials to be associated are associated with the video group, which lays a foundation for the subsequent generation of the target video.

[0072] As an optional embodiment, determining the splicing order between the multiple video groups includes: determining an operation order between video group adding operations, and determining the operation order as the splicing order between the multiple video groups.

[0073] Among them, each time a video group adding operation is performed, a video group can be generated. The operation order refers to the order in which different video group adding operations are performed. For example, the user has performed 5 video group adding operations in succession, and video group 1-1, video group 1-2, video group 1-3, video group 1-4 and video group 1-5 are generated in sequence. Based on this, the splicing order between multiple video groups is video group 1-1, video group 1-2, video group 1-3, video group 1-4 and video group 1-5.

[0074] It can be seen that the implementation of this optional embodiment clarifies the correspondence between the splicing order between the video groups and the operation order between the video group adding operations, which ensures that the target video generated subsequently will not have the problem of inaccurate narrative logic.

[0075] In step S120, video materials to be spliced ​​are respectively determined from the video materials respectively associated with the plurality of video groups, and the plurality of video materials to be spliced ​​are spliced ​​in a splicing order to obtain a target video.

[0076] Specifically, a video material to be spliced ​​is randomly selected from the video materials respectively associated with the plurality of video groups. For example, a video material C-1 to be spliced ​​is randomly selected from the video group 1-1, a video material C-2 to be spliced ​​is randomly selected from the video group 1-2, a video material C-3 to be spliced ​​is randomly selected from the video group 1-3, a video material C-4 to be spliced ​​is randomly selected from the video group 1-4, and a video material C-5 to be spliced ​​is randomly selected from the video group 1-5.

[0077] According to the splicing order of video group 1-1, video group 1-2, video group 1-3, video group 1-4 and video group 1-5, the video material C-1 to be spliced, the video material C-2 to be spliced, the video material C-3 to be spliced, the video material C-4 to be spliced ​​and the video material C-5 to be spliced ​​are spliced ​​in turn to generate the target video for introducing product A.

[0078] As an optional embodiment, video materials to be spliced ​​are respectively determined from video materials respectively associated with multiple video groups, including: determining dubbing audio and dubbing duration of the dubbing audio; determining target video materials from video materials respectively associated with multiple video groups, and determining the total video duration of the multiple target video materials; based on the relationship between the dubbing duration and the total video duration, determining the multiple target video materials as video materials to be spliced.

[0079] The interface for generating the target video may also include an audio input box. A text version of the dubbing may be input in the audio input box, or a voice version of the dubbing may be input. When a text version of the dubbing is input, the text version of the dubbing may be converted into a dubbing audio; when a voice version of the dubbing is input, the dubbing is the dubbing audio. The dubbing duration is the duration of the dubbing audio.

[0080] The target video material refers to the video material randomly selected from different video groups, and the total video duration refers to the total playback duration of these randomly selected video materials. According to the relationship between the dubbing duration and the total video duration, it can be determined whether the determined target video material is determined as the video material to be spliced ​​for subsequent generation of the target video.

[0081] It can be seen that the implementation of this optional embodiment introduces dubbing audio, and determines whether to determine the target video material as the video material to be spliced ​​based on the duration relationship between the dubbing audio and the total video duration, thereby improving the logic of determining the video material to be spliced.

[0082] As an optional embodiment, determining the dubbing audio includes: responding to a dubbing text input operation, determining a dubbing text corresponding to the dubbing text input operation; and converting the dubbing text into dubbing audio.

[0083] Among them, the dubbing text input operation refers to the operation performed in the interface used to generate the target video. After the dubbing text input operation is performed in the interface used to generate the target video, a dubbing text will be obtained. At this time, the dubbing text needs to be converted into dubbing audio in voice form.

[0084] It can be seen that by implementing this optional embodiment, even if the input is a dubbing text, the dubbing text can be converted into dubbing audio, which lays a foundation for adding dubbing to the video later.

[0085] As an optional embodiment, based on the relationship between the dubbing duration and the total video duration, multiple target video materials are determined as video materials to be spliced, including: if the total video duration is greater than or equal to the dubbing duration, multiple target video materials are determined as video materials to be spliced; if the total video duration is less than the dubbing duration, other video materials are determined in sequence from the video materials respectively associated with multiple video groups until the total video duration of the multiple other video materials is greater than or equal to the dubbing duration; wherein the other video materials do not include the target video material; and the other video materials are determined as video materials to be spliced.

[0086] Among them, when the total video length is greater than or equal to the dubbing length, it proves that the dubbing audio can be played completely. Based on this, the target video material determined at this time is determined as the video material to be spliced.

[0087] If the total video length is less than the dubbing length, it means that the dubbing audio has not been played after the target video material has been played. Therefore, the target video material determined at this time cannot be determined as the video material to be spliced.

[0088] At this time, it is necessary to re-determine other video materials from the video materials associated with multiple video groups. It is worth noting that other video materials do not include the target video material determined last time. If the total video duration of the other video materials currently determined is greater than or equal to the dubbing audio, the other video materials are determined as the final video materials to be spliced. If the total video duration of the other video materials currently determined is less than the dubbing audio, the above steps are repeated until the total video duration of the other video materials is greater than or equal to the dubbing duration.

[0089] Figure 4 The following is a schematic diagram of a process for determining video materials to be spliced ​​in an embodiment of the present disclosure, wherein: Figure 4 As shown, first determine the dubbing audio, calculate the dubbing duration of the dubbing audio, and then randomly select a video material in each video group to form a target video material; then determine the total video duration of the target video material; when the total video duration is less than the dubbing audio, reselect another video material from the first video group to re-determine the total video duration of the target video material; judge the relationship between the re-determined total video duration and the dubbing duration, until the total video duration is greater than or equal to the dubbing duration, at which time the determined target video material is determined as the video material to be spliced.

[0090] It can be seen that when implementing this optional embodiment, when the total video length is less than the dubbing length, it is necessary to determine other video materials in sequence from the video materials associated with multiple video groups until the total video length of other video materials is greater than or equal to the dubbing length. This allows the subsequently generated target video to contain complete dubbing audio, which helps the audience understand the video information in the target video.

[0091] As an optional embodiment, the method also includes: determining the number of video generation, and based on the number of video generation, determining the number of videos to be spliced ​​from the video materials respectively associated with multiple video groups; splicing the videos to be spliced ​​belonging to different video groups in a splicing order to obtain a video splicing result; and combining the video splicing result with the dubbing audio to obtain a target video.

[0092] The number of generated videos refers to the number of generated target videos. For example, if the number of generated videos is 20, 20 video materials to be spliced ​​are determined in video group 1-1, 20 video materials to be spliced ​​are determined in video group 1-2, 20 video materials to be spliced ​​are determined in video group 1-3, 20 video materials to be spliced ​​are determined in video group 1-4, and 20 video materials to be spliced ​​are determined in video group 1-5.

[0093] Based on this, according to the splicing order, one is randomly selected from the 20 video materials to be spliced ​​corresponding to each video group for splicing. For example, the video material V01 to be spliced ​​is determined from the 20 video materials to be spliced ​​corresponding to the video group 1-1, the video material V23 to be spliced ​​is determined from the 20 video materials to be spliced ​​corresponding to the video group 1-2, the video material V44 to be spliced ​​is determined from the 20 video materials to be spliced ​​corresponding to the video group 1-3, the video material V71 to be spliced ​​is determined from the 20 video materials to be spliced ​​corresponding to the video group 1-4, and the video material V90 to be spliced ​​is determined from the 20 video materials to be spliced ​​corresponding to the video group 1-5. The video material V01 to be spliced, the video material V23 to be spliced, the video material V44 to be spliced, the video material V71 to be spliced, and the video material V90 to be spliced ​​are spliced ​​to form the first video splicing result. According to the above steps, 19 video splicing results can also be formed. By combining the dubbing audio with the above 20 video splicing results, 20 target videos can be obtained.

[0094] Figure 5 The schematic diagram of the process of batch generating target videos in the embodiment of the present disclosure is shown as follows: Figure 5 As shown, a plurality of preset video groups are determined, video materials associated with the plurality of preset video groups are determined, a splicing order of the plurality of preset video groups is determined, and a number N of video generation is determined.

[0095] According to the number of videos generated N and the batch task information of the above information integration, a video material to be spliced ​​is selected from the preset multiple video groups respectively, the video materials to be spliced ​​are spliced ​​to obtain the target video, and this is repeated N times to finally obtain N target videos.

[0096] It can be seen that by implementing this optional embodiment, multiple target videos can be generated in batches according to the number of videos generated.

[0097] By implementing the embodiments of the present application, multiple video groups can be preset, and there is a preset splicing order between the multiple video groups, and video materials with similar video features are associated in the multiple video groups. Based on this, the target video can be obtained by splicing the multiple video materials to be spliced ​​in the multiple video groups according to the splicing order. Compared with the prior art, by implementing the embodiments of the present application, there is no need to disassemble different video materials, and there is no need to manually edit multiple video materials. By splicing the video materials to be spliced ​​in the multiple video groups, a large amount of target videos can be mixed and cut, which reduces the complexity of generating the target video and improves the efficiency of generating the target video.

[0112] Exemplary Devices

[0113] After introducing the medium of the exemplary embodiment of the present application, next, reference is made to Figure 6 A video generating device according to an exemplary embodiment of the present application will be described.

[0114] See also Figure 6 , Figure 6 FIG. 2 is a block diagram of a video generation device according to an exemplary embodiment of the present application. Figure 6 As shown, a video generating device 600 according to an exemplary embodiment of the present application includes: a video material determining unit 610 and a video splicing unit 620, wherein:

[0115] The video material determination unit 610 is used to determine a plurality of preset video groups, and determine a splicing order between the plurality of video groups and video materials respectively associated with the plurality of video groups; wherein the video materials in the same video group have similar video features;

[0116] The video splicing unit 620 is used to determine the video materials to be spliced ​​from the video materials respectively associated with the multiple video groups, and splice the multiple video materials to be spliced ​​in a splicing order to obtain a target video.

[0117] It can be seen that the implementation Figure 6 The device shown can preset multiple video groups, and there is a preset splicing order between the multiple video groups, and video materials with similar video features are associated in the multiple video groups. Based on this, the target video can be obtained by splicing the multiple video materials to be spliced ​​in the multiple video groups according to the splicing order. Compared with the prior art, the implementation of the embodiment of the present application does not need to disassemble different video materials, and does not need to manually edit multiple video materials. The target video can be generated by splicing the video materials to be spliced ​​in the multiple video groups, mixing and splicing a large amount, which reduces the complexity of generating the target video and improves the efficiency of generating the target video.

[0118] In one embodiment, based on the aforementioned scheme, the video material determination unit 610 determines a plurality of preset video groups and determines video materials respectively associated with the plurality of video groups, including: in response to a video group adding operation, generating a video group corresponding to the video group adding operation; in response to a material association operation for a target video group, selecting video materials to be associated from the original video materials, and determining the video materials to be associated as video materials associated with the target video group.

[0119] It can be seen that by implementing this optional embodiment, a video group that meets the target video splicing requirements can be preset, and the corresponding video materials to be associated are associated with the video group, which lays a foundation for the subsequent generation of the target video.

[0120] In one embodiment, based on the above solution, determining the splicing order between the multiple video groups includes:

[0121] An operation sequence between video group adding operations is determined, and the operation sequence is determined as a splicing sequence between the multiple video groups.

[0122] It can be seen that the implementation of this optional embodiment clarifies the correspondence between the splicing order between the video groups and the operation order between the video group adding operations, which ensures that the target video generated subsequently will not have the problem of inaccurate narrative logic.

[0123] In one embodiment, based on the above solution, respectively determining the video materials to be spliced ​​from the video materials respectively associated with the plurality of video groups includes:

[0124] Determine the dubbing audio and the dubbing duration of the dubbing audio; determine the target video materials respectively among the video materials respectively associated with the multiple video groups, and determine the total video duration of the multiple target video materials; based on the relationship between the dubbing duration and the total video duration, determine the multiple target video materials as the video materials to be spliced.

[0125] It can be seen that the implementation of this optional embodiment introduces dubbing audio, and determines whether to determine the target video material as the video material to be spliced ​​based on the duration relationship between the dubbing audio and the total video duration, thereby improving the logic of determining the video material to be spliced.

[0126] In one embodiment, based on the above scheme, determining the dubbing audio includes:

[0127] In response to a dubbing text input operation, a dubbing text corresponding to the dubbing text input operation is determined; and the dubbing text is converted into dubbing audio.

[0128] It can be seen that by implementing this optional embodiment, even if the input is a dubbing text, the dubbing text can be converted into dubbing audio, which lays a foundation for adding dubbing to the video later.

[0129] In one embodiment, based on the above solution, based on the relationship between the dubbing duration and the total video duration, multiple target video materials are determined as the video materials to be spliced, including:

[0130] If the total video duration is greater than or equal to the dubbing duration, multiple target video materials are determined as video materials to be spliced; if the total video duration is less than the dubbing duration, other video materials are determined in sequence from the video materials respectively associated with the multiple video groups until the total video duration of the multiple other video materials is greater than or equal to the dubbing duration; wherein the other video materials do not include the target video material; the other video materials are determined as video materials to be spliced.

[0131] It can be seen that when implementing this optional embodiment, when the total video length is less than the dubbing length, it is necessary to determine other video materials in sequence from the video materials associated with multiple video groups until the total video length of other video materials is greater than or equal to the dubbing length. This allows the subsequently generated target video to contain complete dubbing audio, which helps the audience understand the video information in the target video.

[0132] In one embodiment, based on the above solution, the device further includes:

[0133] Determine the number of videos to be generated, and based on the number of videos to be generated, determine the number of video materials to be spliced ​​from the video materials respectively associated with the multiple video groups; splice the video materials to be spliced ​​belonging to different video groups in a splicing order to obtain a video splicing result; combine the video splicing result with the dubbing audio to obtain a target video.

[0134] It can be seen that by implementing this optional embodiment, multiple target videos can be generated in batches at one time according to the number of videos to be generated.

[0135] It should be noted that although several modules or units of the video generation device are mentioned in the above detailed description, this division is not mandatory. In fact, according to the embodiments of the present application, the features and functions of two or more modules or units described above can be embodied in one module or unit.
