DETAILED DESCRIPTION OF THE INVENTION

[0013] In the following, in order to clarify the objectives, technical solutions and advantages of the embodiments of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described in conjunction with the drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, and not all embodiments, and all other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without any creative efforts belong to the protection scope of the present invention.

[0014] It should be noted that all user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in the present invention are information and data approved by the user or fully approved by all parties, and the collection, use, and processing of related data must comply with the relevant laws, regulations, and standards of the relevant countries and regions, and a corresponding operation portal will be provided to allow users to choose to approve or reject.

[0015] The following describes application scenarios of the embodiments of the present invention.

[0016] FIG. 1 is an application scenario diagram of a text video generation method provided by an embodiment of the present invention. The text video generation method provided by an embodiment of the present invention can be applied to an application scenario in which a client of a short video platform edits and uploads videos. Specifically, as shown in FIG. 1, the method provided by an embodiment of the present invention can be applied to a terminal device such as a smartphone. A short video platform client runs in the terminal device. A text editing page is set up in the client. The terminal device triggers a corresponding component in response to a user operation to enter the text editing page. A text input area is set up in the file editing page, and the user edits text in the text input area using an input method. Specifically, as shown in the drawing, for example, when a user clicks on the text input area, the text input area enters an editing state and a text input cursor is displayed. At the same time, an input method interface pops up in the text editing page. The user operates the input method interface to enter text in the text input area and generate target text (in the drawing, an "X" represents a letter). After completing the target text entry, the input method interface disappears, and the complete text input area is displayed in the text editing page. Then, by clicking the "Done" button, the target text in the text input area will be rendered, and the video material will be generated and uploaded to the service side of the short video platform (shown as the platform server in the drawing), thereby completing the process of generating a video work from a plain text work and uploading it to the short video platform. Meanwhile, by clicking the "Back" button, the text editing page can be exited, and the details will not be repeated.

[0017] In conventional technology, a short video platform client typically receives a user-created video and implements necessary steps such as transcoding and compression before uploading it to a service's video pool. The service then pushes the video to different users based on the videos in the video pool. However, for videos with plain text content, a short video platform client typically does not provide a function page for editing. This is because, in the plain text editing process, the length of the text is determined by the text content edited by the user. Therefore, when the text is displayed with a fixed font size and line spacing, the font and line spacing can be too small or too large. For example, taking font as an example, if the target text edited by a user contains five Chinese characters, the font size is appropriate when displayed with a fixed font size of 3 (example). However, if the target text edited by a user contains 500 Chinese characters, the font size is too large when displayed with a fixed font size of 3, and the entire content of the target text cannot be displayed on the same screen. On the other hand, because text videos are videos that statically display text (i.e., the video always displays the same frame of content), this can lead to a problem of missing content in the text video generated based on the rendering of the target text. Conversely, in the above example, when displayed at a font size of 5 (example), if the target text edited by the user contains five Chinese characters, the font will be too small, resulting in a problem of the font being too small in the text video generated based on the rendering of the target text, which affects the video display effect. Because the font and line spacing cannot be automatically adapted, the generated text video will not have normal text content, making it difficult to achieve the purpose of video display of the text video.Therefore, in the prior art, each short video platform can usually receive text videos created by users, but cannot automatically generate text videos with good display effects.

[0018] The embodiment of the present invention provides a text video generation method to solve the above problems.

[0019] Referring to Figure 2, Figure 2 is a flow diagram of a text video generation method provided by an embodiment of the present invention. The method of this embodiment can be applied to a terminal device, and the text video generation method includes the following steps:

[0020] In step S101, a text editing page is displayed, where the text editing page includes a text input area.

[0021] For example, the schematic diagram of the application scenario shown in FIG. 1 shows that a short video platform client (hereinafter referred to as the client) launches a text editing page in response to a trigger operation. Specifically, the functional component for triggering the text editing page may be set on the client's video playback page (i.e., the default page for short video applications) or on the video shooting page for uploading video works, i.e., the frame page. After receiving a user's trigger operation on the functional component, the text editing page is displayed.

[0022] Furthermore, a text input area is set in the text editing page. For example, after receiving a user's click operation on the text input area, the terminal device activates the text input area to obtain input focus, and then the user can input character information such as text or symbols into the text input area using an input method. Here, the position and size of the text input area can be set as needed and are not limited here.

[0023] In step S102, in response to a first input command on the text editing page, display target text in a text input area, where the target text has a first font state in the text input area, the first font state characterizing a font size and / or line spacing of the target text, the first font state being determined by a length of the target text.

[0024] For example, after the text input area has the input focus, the terminal device receives a first input command input by the user, where the first input command is used to generate text information of the target text, and the first input command may include an identifier corresponding to a specific character or symbol, or an identifier for forming the pronunciation element of the character, such as Chinese pinyin, alphabet, etc., which are not repeated here. After receiving the first input command, the terminal device converts the first input command into corresponding text or symbols according to an input method in the system, and displays it in the text input area to form the target text, which is a text to be finally released.

[0025] Here, the target text may include one or more characters or symbols. Here, symbols input and displayed in the text input area include visible symbols and invisible symbols, and visible symbols include symbols for text editing such as commas and periods, and details will not be repeated. It should be noted that invisible symbols include spaces, blank lines, line breaks, etc. The target text composed of characters and symbols has a paragraph structure, for example, the target text is divided into multiple paragraphs and includes blank lines, etc., thereby making the target text in the text input area visually more readable.

[0026] Furthermore, the target text in the displayed text input area has a first font state, where the first font state characterizes the font size and / or line spacing of the target text, and the first font state is determined by the length of the target text. Specifically, the longer the length of the target text, the smaller the font size of the text and symbols in the target text and / or the smaller the line spacing between lines in the target text. Conversely, the shorter the length of the target text, the larger the font size of the text and symbols in the target text and / or the larger the line spacing between lines in the target text. In short, when the length of the target text is longer, the terminal device compresses the target text in the text input area so that the text input area can contain more characters and symbols. When the length of the target text is shorter, the font is enlarged to make the content of the target text more prominent and improve the visual display effect. Of course, it is understood that there is a certain tolerance for adjusting the first font state (i.e., the font size and / or line spacing of the target text), and that there is a predetermined non-linear correspondence between the first font state and the length of the target text, the specific implementation of which will be described in subsequent examples and will not be repeated here.

[0027] Further, based on the above description of the target text implementation, the length of the target text may be determined by the number of characters in the target text, the total number of characters and symbols in the target text, or the overall occupancy length of the target text in the text input area. For example, if the target text includes a blank line character, one blank line character occupies one blank line in the text input area. Therefore, if the target text includes a blank line, determining the length of the target text based on the overall occupancy length of the target text in the text input area can more accurately measure the actual length of the target text, thereby improving the display effect of the final target video.

[0028] 3 is a schematic diagram of displaying target text in a text input area according to an embodiment of the present invention. As shown in FIG. 3, in this embodiment, the total number of characters in the target text is the length of the target text. The terminal device continuously displays the corresponding target text in the text input area based on a first input command. When the length of the target text is N=10 (time 1), the first font state of the target text is Info_1, and the font size characterizing each character and symbol in the target text is #4. With successive input of the first input command, the length of the target text continues to increase. When the length of the target text is N=50 (time 2), the first font state of the target text is Info_2, and the font size characterizing each character and symbol in the target text is #5 (one size smaller than #4). This achieves the purpose of dynamically displaying the font size of the target text in the text input area.

[0029] Further, based on the above-mentioned embodiment, the first font state further includes information characterizing a line spacing, and the line spacing of the target text can be further adjusted according to the first font state. For example, when the length of the target text N is 10, the first font state of the target text is Info_1, the font size characterizing each character and symbol in the target text is #4 size, and the line spacing is 1; when the length of the target text N is 50, the first font state of the target text is Info_2, the font size characterizing each character and symbol in the target text is #5 size, and the line spacing is 0.8.

[0030] Alternatively, in another possible implementation, the line spacing of the target text can also be determined based solely on the length of the target text. For example, as shown in Figure 3, when the length of the target text N is 10, the first font state of the target text is Info_1 and the line spacing of the target text is characterized as 1, and when the length of the target text N is 50, the first font state of the target text is Info_2 and the line spacing of the target text is characterized as 0.8.

[0031] In step S103, a target video is generated to display the target text in the text input area.

[0032] For example, target text in a text input area has a corresponding first font state, and then the text input area is rendered to generate a video having a predetermined duration, i.e., a target video. Here, since the target video corresponds to a restored display of the target text in the text input area, the target video not only displays the text content of the target text but also restores the first font state of the target text, i.e., the character size and / or line spacing of the target text. As a result, the target text displayed in the target video can visually match the target text displayed in the text input area. Furthermore, during the process of a user editing the text content in the text input area, the display effect of the final target video (i.e., text video) can be accurately predicted, and the video quality of the final target video can be improved. This avoids problems such as text being too small to view or too large to display the entire text in the text video.

[0033] In one possible implementation, as shown in FIG. 4, the specific implementation of step S103 is as follows: Step S1031: generating a rendered image including the target text having a first font state based on the target text; Step S1032, determining a video duration based on the length of the target text; Step S1033 includes generating a target video based on the video duration and the rendered image.

[0034] For example, after inputting a target text in the text input area, the target text in the text input area with a first font state is converted into an image, i.e., a rendering image, based on the target text in the text input area. There are various ways to convert text into an image, such as taking a picture of the text input area to generate a rendering image, or inputting the target text and the corresponding first font state as input parameters into an image converter to generate a corresponding rendering image. The specific steps for converting text into an image are known to those skilled in the art and will not be repeated here.

[0035] Furthermore, a corresponding video duration is determined based on the length of the target text, such as the number of characters in the target text, and the finally generated target video needs to match the user's viewing time when displaying the target text, so the longer the target text, the longer the time required for the user to view the target text in the target video. Therefore, by setting a video duration that matches the length of the target text, the display effect of the target video can be improved. Then, using the rendering image as a material and the video duration as a parameter, video conversion is performed to generate a static video, i.e., the target video.

[0036] In this embodiment, a text editing page including a text input area is displayed, and in response to a first input command on the text editing page, target text is displayed in the text input area, and a target video is generated to display the target text in the text input area, where the target text has a first font state in the text input area, the first font state characterizing the font size and / or line spacing of the target text, and the first font state is determined by the length of the target text. By configuring the text input area and dynamically changing the font size and / or line spacing of the target text edited in the text input area according to the length of the text, and then converting the target text in the text input area, the generated target video can clearly and comprehensively display the entire content of the target text, thereby achieving the purpose of generating text videos based on plain text, improving the video generation efficiency in the video creation process, and increasing the diversity of video content on the video platform.

[0037] 5 is another flow diagram of a text video generating method provided by an embodiment of the present invention. Based on the embodiment shown in FIG. 2, this embodiment further refines step S102 and adds a step of configuring background images and background music for the target video. The text video generating method includes: Step S201: displaying a text editing page, where the text editing page includes a text input area; Step S202: generating a target text in response to a first input command and obtaining a total number of characters in the target text; Step S203 includes determining a first font state based on the total number of characters and the area size of the text input area.

[0038] For example, an editing page can be displayed, and in response to a first input command on the editing page, corresponding characters and symbols can be generated based on the information in the first input command, and a target text can be further generated. Specific implementation steps have been described in detail in the embodiment shown in Fig. 2 and will not be repeated here. Then, the total number of characters in the target text can be obtained by calling a statistical function to process the string corresponding to the target text. The total number of characters in this embodiment may be only the number of characters in the target text, or the sum of the number of characters and the number of symbols.

[0039] For example, the text input area of ​​the text editing page has an area size. For example, if the text input area is rectangular, the area size of the text input area may be the length and width of the text input area. Furthermore, the area size of the text input area may indicate the area of ​​the text input area, and the larger the area of ​​the text input area, the greater the total number of characters that can be displayed. The area size of the text input area is a predetermined fixed value and can be determined according to the screen pixel size of the terminal device, and will not be repeated here.

[0040] Furthermore, after determining the total number of characters and the area size of the text input area, first calculate the total area of ​​the text input area based on the area size of the text input area, then use the ratio between the total area and the total number of characters to obtain the unit area occupied by the font size (and symbol), and further determine the font size and / or corresponding line spacing, i.e., the first font state, based on the unit area and a predetermined correction coefficient. The above-mentioned implementation is suitable for roughly calculating the first font state because it does not take into account the influence of blank areas due to line breaks and blank lines.

[0041] In another possible implementation, the area size includes an area horizontal size and an area vertical size, and as shown in FIG. 6, the specific implementation of step S203 is as follows: Step S2031: determining a number of characters per line based on a font width corresponding to a base font size and an area horizontal size, the number of characters per line characterizing the number of characters that can be displayed in one line of the text input area; Step S2032: determining a first vertical size based on the number of characters per line and the total number of characters; Step S2033 includes determining a first font state based on the first vertical size and the area vertical size.

[0042] FIG. 7 is a schematic diagram of the area size of a text input area provided by an embodiment of the present invention. As shown in FIG. 7, the text input area in the client's text editing page is a vertically oriented rectangular area (suitable for a smartphone display screen). The horizontal size of the area is illustrated as dim_x, and the vertical size of the area is illustrated as dim_y. The user inputs target text into the text input area. The base font size is the font size of a given input character and has a corresponding font width and font height. For example, if the font is a Chinese font, the font width and font height of the text may be the same. The number of characters per line, i.e., the number of characters that can be displayed per line in the text input area, can be determined based on the proportional value between the horizontal size of the area and the font width corresponding to the base font size. For example, 20 characters. The total number of lines can then be obtained by dividing the total number of characters in the target text by the number of characters per line. The average line height is obtained based on the font height and base line spacing, and the product of the average line height and the total number of lines can be calculated to obtain the first vertical size, indicated as dim_Y in the drawing. Here, the base line spacing may be a predetermined value, similar to the base font size, and will not be repeated here with examples.

[0043] Furthermore, after determining the first vertical size, the first vertical size is compared with the area vertical size. If the first vertical size is larger than the area vertical size, it indicates that the font size and / or line spacing are larger at this time, resulting in the text input area being exceeded, making it impossible to display all the content of the target text in a static display manner in the target video to be generated subsequently. In this case, the base font size and / or base line spacing, which affect the first vertical size, are reduced to obtain the first font state. Specifically, for example, the base font size and / or base line spacing are multiplied by a proportional coefficient less than 1 to obtain the first font state. In another case, if the first vertical size is smaller than the area vertical size, it indicates that the font size and / or line spacing are smaller at this time, resulting in the target text not being reasonably laid out in the text input area, affecting the display effect of the target video to be generated subsequently. In this case, the base font size and / or base line spacing, which affect the first vertical size, are increased to obtain the first font state. Specifically, for example, the base font size and / or the base line spacing is multiplied by a proportional coefficient greater than 1 to obtain the first font state.

[0044] Here, for example, the proportional relationship between the first vertical size and the vertical size of the area can be determined by adjusting the base font size and / or the proportional coefficient between the base lines. As shown in FIG. 8, for example, a specific implementation of step S2033 is as follows: Step S2033A: obtaining a proportional value between the first vertical size and the area vertical size; Step S2033B, if the proportional value is less than the first proportional threshold, determining a first font state based on a base font size and / or a base line spacing; Step S2033C includes: if the proportional value is greater than the first proportional threshold, reducing the base font size and / or reducing the base line spacing according to the proportional value to obtain a first font state.

[0045] For example, after determining the first vertical size and the area vertical size, a proportional value between the first vertical size and the area vertical size is calculated. For example, if the first vertical size is 8 (a predetermined unit) and the area vertical size is 10, the proportional value between the first vertical size and the area vertical size is 0.8. The first proportional threshold characterizes the proportion of the text input area, i.e., the screen proportion after generating the target video. When the first proportional threshold is 1, it characterizes the entire area of ​​the text input area, and when the first proportional threshold is 0.8, it characterizes 80% of the area (the ideal display area) of the text input area. Furthermore, in a possible case, if the proportional value is smaller than the first proportional threshold, it indicates that the target text does not exceed the text input area, and the generated target video will not be unable to display all the target text. At the same time, the base font size and / or the base line spacing can be considered ideal parameters set according to specific needs, and therefore the base font size and / or the base line spacing can be set to the first font state.

[0046] In another possible case, if the proportional value is greater than the first proportional threshold, it indicates that the target text exceeds the text input area or the ideal display area of ​​the text input area, which may result in the generated target video being unable to display all of the target text. In this case, the base font size or the base line spacing is adjusted based on the proportional value, where the first proportional threshold is, for example, 1. Specifically, for example, if the proportional value is greater than or equal to 0.8 and less than 1, the font size is reduced by one level, and if the proportional value is greater than or equal to 0.6 and less than 0.8, the font size is reduced by two levels. By analogy in this way, the target font size and / or the target line spacing obtained by reducing the base font size and / or the base line spacing are determined as the first font state.

[0047] In step S204, display the target text in the text entry area based on the first font state.

[0048] In this embodiment, a proportional value between the first vertical size and the vertical size of the area is calculated, and the corresponding first font state is dynamically determined by reducing the proportional value according to the base font size and the base line spacing, thereby more accurately controlling the length of the target text in the text input area, improving the content length of the final generated target video, and improving the display effect of the text video and the user's viewing experience.

[0049] In step S205, in response to a second input command to the text edit page, a background image is displayed within the text edit page.

[0050] For example, based on the above steps, a component for configuring a background image is further configured on the text editing page. A user can trigger the component through an operation command to display the background image on the text editing page. Specifically, the display area corresponding to the background image is a background image area, which covers the text input area. FIG. 9 is a schematic diagram of a background image provided by an embodiment of the present invention. As shown in FIG. 9, after receiving a user's click on the "Add Background" control, the terminal device generates and executes a second input command to automatically add the background image to the background image area on the file editing page, where the background image area covers the text input area and the text input area is located at the center of the background image. In a subsequent step, the background image area is rendered as a target area to generate a corresponding target video. The target text in the generated target video is then displayed on the background image, improving the display effect of the target text in the target video.

[0051] Here, for example, the target text further has a second font state, and the second font state characterizes the font color of the target text. As shown in FIG. 10, the specific implementation of step S205 is as follows: step S2051, in response to a second input command, matching a target color based on a second font state, where a color difference between the target color and the font color is greater than a color difference threshold; Step S2052 includes obtaining a background image whose main color is the target color based on the predetermined gallery, and displaying the background image in the text editing page.

[0052] For example, after receiving the second input command, the second font state of the target text, i.e., the font color of the target text, is first obtained. The second font state may be set by an operation command input by a user. The specific implementation is conventional technology, and details will not be repeated. Then, based on the font color characterized by the second font state, another color, i.e., the target color, whose color difference is greater than the color difference threshold is determined. Simply put, a color with a high font color difference of the target text is determined as the target color. For example, if the font of the target text is black, the target color may be white, light green, light blue, etc. (colors whose color difference from black is greater than the threshold). Then, a main color is obtained from a predetermined gallery as a background image of the target color, thereby ensuring that the background image has a higher contrast with the font color of the target text. This avoids the problem of the target text being difficult to distinguish due to the similar colors of the background image and the target text, and improves the display clarity of the target text in the target video.

[0053] In step S206, background music is obtained based on the background image.

[0054] Furthermore, after obtaining a background image, background music that matches the background image is automatically selected based on the background image. For example, if the content of the background image is "landscape," a song tag for music with a matching soothing rhythm is obtained based on the semantic information of the background image. If the content of the background image is "people dancing on a dance floor," a song tag for music with a matching dynamic rhythm is obtained based on the semantic information of the background image. Then, a corresponding target piece of music is selected as background music from a music library based on the song tag. Here, a specific implementation of obtaining the semantic information of a background image and obtaining the corresponding song tag based on the semantic information can be realized using a pre-trained image semantic model, so it will not be repeated here.

[0055] In the steps of this embodiment, by obtaining background music that matches the background image, the background image and the background music have semantic consistency, the video expression of the final generated target video is better, and the quality of the text video is improved.

[0056] In step S207, a target video is generated based on the target text in the text input area, the background image, and the background music.

[0057] The process of obtaining a target text, background image, and background music, and performing rendering based on the target text and background image to obtain a corresponding rendered image has already been described in the embodiment shown in Fig. 2, and will not be repeated here. Then, the rendered image and the background music are merged and converted to obtain a target video. Here, for example, the video duration of the target video in this embodiment may be determined by the music duration of the background music, and the specific implementation steps have already been described in the embodiment shown in Fig. 2, and will not be repeated here.

[0058] Of course, in other possible embodiments, after obtaining the target text and the corresponding first font state, only the background image or background music corresponding to the target text can be obtained, and then the target video can be generated based on the target text and the background image, or the target video can be generated based on the target text and the background music, where it is understood that the background music is determined based on the semantic information of the target text. The specific implementation process is the same as the implementation process in the above-mentioned embodiment steps, and the details will not be repeated.

[0059] Corresponding to the text-video generating method of the above embodiment, Fig. 11 is a block diagram of the text-video generating device provided by the embodiment of the present invention. For convenience of explanation, only the parts related to the embodiment of the present invention are shown. Referring to Fig. 11, the text-video generating device 3 includes: an editing module 31 for displaying a text editing page, the text editing page including a text input area; a display module 32 for displaying target text in a text entry area in response to a first input command on the text editing page, the target text having a first font state in the text entry area, the first font state characterizing a font size and / or line spacing of the target text, the first font state being determined by a length of the target text; A generation module 33 for generating a target video for displaying the target text in the text input area is provided.

[0060] In one embodiment of the present invention, the display module 32 specifically generates a target text in response to a first input command, obtains the total number of characters in the target text, determines a first font state based on the total number of characters and the area size of the text input area, and displays the target text in the text input area based on the first font state.

[0061] In one embodiment of the present invention, the area size includes an area horizontal size and an area vertical size. When determining the first font state based on the total number of characters and the area size of the text input area, the display module 32 specifically determines the number of characters per line based on a font width corresponding to the base font size and the area horizontal size, where the number of characters per line characterizes the number of characters that can be displayed in one line of the text input area. The display module 32 determines a first vertical size based on the number of characters per line and the total number of characters, and determines the first font state based on the first vertical size and the area vertical size.

[0062] In one embodiment of the present invention, when determining the first font state based on the first vertical size and the area vertical size, the display module 32 specifically obtains a proportional value between the first vertical size and the area vertical size, and if the proportional value is smaller than a first proportional threshold, determines the first font state based on the base font size and / or the base line spacing; and if the proportional value is larger than the first proportional threshold, reduces the base font size and / or the base line spacing based on the proportional value to obtain the first font state.

[0063] In one embodiment of the present invention, the generation module 33 specifically generates a rendering image including a target text having a first font state based on the target text, determines a video duration based on the length of the target text, and generates a target video based on the video duration and the rendering image.

[0064] In one embodiment of the present invention, before generating a target video for displaying the target text in the text input area, the display module 32 further displays a background image in the text editing page in response to a second input command for the text editing page, and the generation module 33 specifically generates the target video based on the target text in the text input area and the background image.

[0065] In one embodiment of the present invention, the target text further has a second font state, which characterizes the font color of the target text. When the display module 32 displays a background image within the text editing page in response to a second input command for the text editing page, the display module 32 specifically matches the target color based on the second font state in response to the second input command, where the color difference between the target color and the font color is greater than a color difference threshold. The display module 32 obtains a background image whose main color is the target color based on a predetermined gallery, and displays the background image within the text editing page.

[0066] In one embodiment of the present invention, the generation module 33 further obtains background music based on the background image, and when generating a target video for displaying the target text in the text input area, the generation module 33 specifically generates the target video based on the target text in the text input area and the background music.

[0067] Here, the editing module 31, the display module 32, and the generating module 33 are connected in sequence. The text video generating device 3 provided by this embodiment can implement the technical solutions of the above-mentioned method embodiments, and its realization principles and technical effects are similar, so this embodiment will not be repeated here.
