[0025] The following section provides a detailed description of various example implementations of this scheme, with reference to the accompanying drawings.

[0026] Example Environment

[0027] Figure 1 illustrates a schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented. In environment 100, an electronic device 110 and a media content generation system 136 are deployed. In some embodiments, the electronic device 110 receives a media generation request 130 from a user 140. Subsequently, the electronic device 110 invokes the media content generation system 136 to generate target media content 120 based on the media generation request 130. In some embodiments, the media content generation system 136 may run on a local device or a remote device.

[0028] In some embodiments, electronic device 110 may include various types of computing systems / servers providing computing capabilities, and electronic device 110 may include terminal devices. Such terminal devices may be any type of mobile terminal, fixed terminal, or portable terminal, including mobile phones, desktop computers, laptop computers, notebook computers, netbook computers, tablet computers, media computers, multimedia tablets, handheld computers, portable gaming terminals, VR / AR devices, personal communication system (PCS) devices, personal navigation devices, personal digital assistants (PDAs), audio / video players, digital cameras / camcorders, positioning devices, television receivers, radio receivers, e-book devices, gaming devices, or any combination thereof, including accessories and peripherals of these devices or any combination thereof. In some embodiments, electronic device 110 may also support any type of user-facing interface (such as "wearable" circuitry). Electronic device 110 may, for example, include computing systems / servers such as mainframes, edge computing nodes, computing devices in cloud environments, virtual machines, etc. Although shown as a single device, electronic device may include multiple physical devices.

[0029] It should be understood that the structure and function of the various elements in environment 100 are described for illustrative purposes only and do not imply any limitation on the scope of this disclosure.

[0030] The following description will continue with reference to the accompanying drawings, which will provide some exemplary embodiments of this disclosure.

[0031] Generate media content

[0032] Figure 2 shows a flowchart of an example process 200 for generating media content according to some embodiments of the present disclosure. Process 200 can be implemented at electronic device 110. Process 200 will now be described with reference to Figure 1.

[0033] As shown in Figure 2, in box 210, electronic device 110 acquires a first descriptive text about the media content to be generated.

[0034] In some embodiments, the electronic device 110 may acquire a first descriptive text (e.g., script content) input by the user. In some embodiments, the first descriptive text may also be determined based on the user's selection of existing text. For example, the user may select existing script content as the first descriptive text.

[0035] Additionally, the first descriptive text can also be generated based on user input or user selection.

[0036] The following describes an example process for generating media content according to an embodiment of the present disclosure with reference to the media content generation system 136 shown in FIG3.

[0037] Figure 3 illustrates a schematic diagram of an example framework 300 of a media content generation system 136 according to some embodiments of the present disclosure. As shown in the example framework 300 of Figure 3, the media content generation system 136 may include a text expansion entity 310 (optional), a target description entity 320 (e.g., a plot description entity), a picture description entity 330, an audio generation entity 340 (optional), and a picture generation entity 350. As an example, the multiple entities mentioned herein can be implemented as appropriate machine learning models to generate corresponding output results based on the received content. As an example, the text expansion entity 310, the target description entity 320, and the picture description entity can be implemented as language models with different text processing capabilities. The audio generation entity 340 can be implemented as a speech model that generates audio content based on text. The picture generation entity 350 can be implemented as a visual model that generates image content based on text. This disclosure is not intended to limit the specific construction method of the entities. The processing capabilities of each entity are described in the embodiments disclosed later, and will not be repeated here.

[0038] In some embodiments, referring to FIG3, the electronic device 110 can utilize the target description entity 320 to generate a first descriptive text about the media content to be generated based on a media generation request. As an example, the electronic device 110 can receive a media generation request 130 from a user 140, and invoke the target description entity 320 to generate a first descriptive text (e.g., a script) of the media content to be generated corresponding to the media generation request 130. As an example, the media generation request 130 may include prompts, such as requirements for the storyline, character design, and art style (e.g., ink painting style, realistic style, etc.) of the media content to be generated. As an example, the first descriptive text may include, for example, a description of the storyline and character features of the media content to be generated. As an example, the media content may be, for example, video content, graphic content (e.g., comics), etc.

[0039] In some embodiments, continuing to refer to FIG3, the electronic device 110 may, in response to receiving a media generation request 130, expand the prompt item of the media generation request using the text expansion entity 310 to generate expanded text content associated with the media generation request 130. It is understood that the expanded text content is derived from the media generation request 130, and is more complete and specific than the prompt item in the media generation request 130.

[0040] In some embodiments, continuing to refer to FIG3, the electronic device 110 may utilize the target description entity 320 to process extended text content and generate a first description text about the media content to be generated.

[0041] In some embodiments, continuing to refer to FIG3, the electronic device 110 may also obtain reference information associated with the media generation request.

[0042] In some embodiments, the reference information may include reference media content associated with the media generation request 130. As an example, the media generation request 130 may be a continuation request for the reference media content. That is, the media generation request 130 may create a media content generation request that continues the plot of the reference media content based on the storyline and / or character portrayals corresponding to the reference media content.

[0043] In some embodiments, the media generation request 130 may be a request issued by user 140 in a video continuation scenario. User 140 may, for example, request continuation of reference media content. The reference media content may be included in a media content set, which stores multiple media content items, including the reference media content.

[0044] In some embodiments, a media content set is associated with multiple media contents, which are organized based on a tree structure of a directed acyclic graph. The tree structure includes multiple nodes corresponding to the multiple media contents, and the edges in the tree structure indicate the content association between the media contents corresponding to two nodes (e.g., plot development relationship, such as the plot development of media content A being the plot development of media content B). As an example, the electronic device 110 can traverse the tree structure based on a depth-first search algorithm to determine at least one media content associated with a reference media content. In some embodiments, the reference information may include a reference media content associated with the media generation request 130 and at least one media content associated with the reference media content.

[0045] In some embodiments, continuing to refer to FIG3, the electronic device 110 can utilize the text extension entity 310 to generate extended text content based on reference information and the media generation request 130. As an example, the extended text content may include character descriptions (e.g., physical features, clothing features, etc.) and scene descriptions (e.g., architectural features, etc.) from the reference media content, thereby ensuring that the subsequently generated media content remains consistent with the relevant descriptions in the reference media content. In this way, the extended text content can take into account both the media generation request and the reference media content, enabling the generated media content to continue the character characteristics, scene features, and plot development of the previous media content while satisfying the media generation request 130.

[0046] As shown in Figure 2, in box 220, the electronic device uses a first processing entity (e.g., screen description entity 330) to generate multiple second description texts based on the first description text. These multiple second description texts can describe the visual information of the media content to be generated (e.g., a description of the screen). As an example, compared to the first description text, the multiple second description texts contain more detailed descriptions of the screen. For instance, the first description text may mention a first scene, and the second description text can add more detailed descriptions of the first scene. For example, the second description text may include elements present in the first scene (e.g., trees, buildings, etc.), the overall screen style, etc., so that the subsequent model can generate the corresponding screen based on the multiple second description texts.

[0047] In some embodiments, the first descriptive text may include plot description text for a first chapter, and the second descriptive text may include scene description text corresponding to multiple storyboard segments of the first chapter. As an example, the multiple second descriptive texts may, for example, describe multiple storyboard segments of the media content to be generated. Multiple storyboard segments can, for example, be understood as visual representations of multiple scenes in the media content to be generated.

[0048] In some embodiments, continuing to refer to FIG3, the electronic device 110 can acquire context information associated with the first chapter, the context information being determined based on at least one second chapter associated with the first chapter. As an example, the at least one second chapter can be a preceding chapter of the first chapter. That is, the first chapter can be a new creation based on the plot content of at least one second chapter.

[0049] In some embodiments, continuing to refer to FIG3, the electronic device 110 can utilize a first processing entity to generate multiple second description texts based on the plot description text and context information. As an example, the second description texts can be obtained by supplementing the scene description content based on the plot description text and context information.

[0050] In some embodiments, continuing to refer to FIG3, the contextual information may indicate: character setting information associated with at least one second chapter. As an example, character setting information may include a visual content description of the character (e.g., the character's physical characteristics, clothing characteristics, etc.), a personality content description of the character (e.g., kind, brave, etc.), or an information content description of the character (e.g., gender, age, story, etc.).

[0051] In some embodiments, continuing to refer to FIG3, the context information may indicate scene setting information associated with at least one second chapter. As an example, scene setting information may include screen background, lighting effects, or scene elements (e.g., buildings, props, etc.).

[0052] In some embodiments, continuing to refer to FIG3, the contextual information may indicate: plot description text associated with at least one second chapter. As an example, the plot description text may include storyline, background information, or major events, etc.

[0053] As shown in Figure 2, in box 230, electronic device 110 uses a second processing entity to generate multiple media materials corresponding to multiple second descriptive texts. As an example, as shown in Figure 3, the third processing entity can be screen generation entity 350.

[0054] In some embodiments, continuing to refer to FIG3, the first descriptive text includes a character description. The electronic device 110 can generate a visual representation of at least one character based on the character description. Further, the electronic device 110 can utilize a second processing entity (e.g., image generation entity 350) to generate multiple media materials corresponding to multiple second descriptive texts based on the visual representation of at least one character. By pre-generating the visual representation of the character, the visual representation of the character can remain consistent across multiple media materials.

[0055] In some embodiments, the multiple media materials may include: multiple video clips corresponding to multiple second descriptive texts, or multiple images corresponding to multiple second descriptive texts.

[0056] As shown in Figure 2, in box 240, electronic device 110 generates target media content based on multiple media materials. As an example, electronic device 110 can merge multiple video clips into a complete video content as the target media content.

[0057] In some embodiments, continuing to refer to FIG3, the electronic device 110 may also utilize the audio generation entity 340 to generate audio content of the media content to be generated based on the first descriptive text. As an example, the audio content may include background music (e.g., background music) of the media content to be generated. As an example, the audio content may also include voice-over (e.g., dialogue voices of characters in the media content, etc.) of the media content to be generated.

[0058] In some embodiments, continuing to refer to FIG3, the electronic device 110 can generate target media content 360 based on audio content and multiple media materials. As an example, the electronic device 110 can match audio content with corresponding media materials and merge the audio content and multiple media materials to generate target media content 360.

[0059] In some embodiments, continuing to refer to FIG3, the electronic device 110 may also create a node corresponding to the target media content 360 in the media content set to store the target media content 360 in the media content set.

[0060] Figures 4A and 4B illustrate example interfaces 400A to 400B according to some embodiments of the present disclosure. Interfaces 400A to 400B may, for example, be provided by a client.

[0061] In some embodiments, as shown in interface 400A of FIG4A, the client can obtain a media generation request initiated by user 140 based on input control 405. This media generation request may, for example, indicate prompts entered by the user, such as script description text about the chapter content to be generated.

[0062] As an example, the media content to be generated can correspond to the first chapter of a collection of works. Further, electronic device 110 (e.g., client or server) can use text extension entity 310 to extend the prompts and generate extended text content. Electronic device 110 can use target description entity 320 to generate a first description text for the first chapter based on the extended text content and previous chapters associated with the first chapter. Further, scene description entity 330 can generate multiple second description texts corresponding to multiple storyboard scenes based on the first description text. Further, scene generation entity 350 can generate multiple media materials (e.g., multiple video clips or multiple images) based on the multiple second description texts. Additionally, audio content (e.g., voice-over, background music) can be generated based on the first description text using audio generation entity 340. Finally, electronic device 110 can generate target media content based on multiple media materials and audio content.

[0063] In some embodiments, as shown in interface 400B of FIG4B, the client can present target media content 360 on interface 400B. Such target media content 360 corresponds, for example, to a new chapter in a collection. As an example, a chapter may include comic content consisting of multiple images (generated based on multiple storyboard description texts) corresponding to multiple storyboards. Alternatively, the chapter may include video content consisting of multiple video clips (generated based on multiple storyboard description texts) corresponding to multiple storyboards.

[0064] Based on the interaction process described above, embodiments of this disclosure can generate media content that meets the user's media generation request. Furthermore, embodiments of this disclosure can also expand existing media content by combining it with existing media content (e.g., reference media content and / or existing chapter content), ensuring that the generated media content continues the existing media content in terms of plot and maintains consistency in character design and scene features. In addition, embodiments of this disclosure can incorporate user interaction content, making the generated target media content better meet the user's needs. Therefore, the efficiency of media content generation is improved.
