Description

Technical Field

[0001] This disclosure relates to the field of image processing technology, and more particularly to a video generation method, apparatus, electronic device, and storage medium. Background Technology

[0002] Currently, in fields such as animation, video processing, or game development, video production is often required. During the video production process, it is usually necessary to consider how the object attributes in the video frame sequence change. The object can be a point in the video frame, a local image, or the entire image. The object attributes can be point position or rotation angle, etc.

[0003] In existing technologies, there are generally two ways to determine how object attributes change. One way is to use interpolation algorithms to directly connect two objects, achieving a linear transition between object attributes. This transition can result in abrupt visual changes during video frame transitions. The other way is to use Bézier curves to make the transition trajectory between two object attributes conform to the curve. However, when using Bézier curves for video production, the control points are not directly located on the curve, leading to jitter during the transition. Summary of the Invention

[0004] This disclosure provides a video generation method, apparatus, electronic device, and storage medium to improve the smoothness and stability of video playback, making video playback more natural and enhancing the user experience.

[0005] In a first aspect, embodiments of this disclosure provide a video generation method, the method comprising:

[0006] Obtain the display parameters of the image to be processed under at least one display metric;

[0007] Based on the display parameters and the preset video playback duration, determine at least one target display function associated with the image to be processed;

[0008] When the video display conditions are met, the target playback parameters of the image to be processed at at least one playback timestamp within the video playback duration are determined based on the at least one target display function; wherein, the number of the target display functions is related to the number of the display indicators;

[0009] The image to be processed is played based on the target playback parameters, and a target video is generated.

[0010] Secondly, embodiments of this disclosure also provide a video generation apparatus, the apparatus comprising:

[0011] The sharpening parameter acquisition module is used to obtain the image sharpening parameters of the image to be rendered;

[0012] The display parameter acquisition unit is used to acquire the display parameters of the image to be processed under at least one display metric.

[0013] The target display function determination unit is used to determine at least one target display function associated with the image to be processed based on the display parameters and the preset video playback duration.

[0014] The target playback parameter determination unit is used to determine the target playback parameters of the image to be processed at at least one playback timestamp within the video playback duration based on the at least one target display function when the video display conditions are detected to be met; wherein, the number of the target display functions is related to the number of the display indicators;

[0015] The target video generation unit is used to play the image to be processed based on the target playback parameters and generate a target video.

[0016] Thirdly, embodiments of this disclosure also provide an electronic device, the electronic device comprising:

[0017] One or more processors;

[0018] Storage device for storing one or more programs.

[0019] When the one or more programs are executed by the one or more processors, the one or more processors implement the video generation method as described in any of the embodiments of this disclosure.

[0020] Fourthly, embodiments of this disclosure also provide a storage medium containing computer-executable instructions, which, when executed by a computer processor, are used to perform the video generation method as described in any of the embodiments of this disclosure.

[0021] Fifthly, embodiments of this disclosure also provide a computer program product, including a computer program that, when executed by a processor, implements the video generation method as described in any of the embodiments of this disclosure.

[0022] The technical solution of this disclosure, when producing a video, can first obtain the display parameters of the image to be processed under at least one display metric. Then, based on the display parameters and a pre-set video playback duration, at least one target display function associated with the image to be processed is determined. When the video display conditions are met, based on the at least one target display function, the target playback parameters of the image to be processed under at least one playback timestamp within the video playback duration are determined. Thus, the image to be processed is played based on the target playback parameters, and the target video is generated. This solves the problem of poor video playback effect in the prior art when using interpolation algorithms or Bézier curves to produce videos. It achieves the precise control of the playback parameters under each playback timestamp by combining the display parameters of the image to be processed under at least one display metric and the video playback duration. The target display function represents the target playback parameters of the image to be processed under each playback timestamp within the video playback duration, thereby ensuring the smoothness and stability of video playback, making the video playback more natural, and improving the user experience.

[0043] It is understood that the data involved in this technical solution (including but not limited to the data itself, the acquisition or use of the data) shall comply with the requirements of relevant laws, regulations and related provisions.

[0044] Before introducing this technical solution, an exemplary application scenario can be provided. This technical solution can be applied to any scenario requiring video production. For example, in any scenario such as animation, video processing, or game development, when it is necessary to create a video based on imported images, the technical solution provided in the embodiments of this disclosure can be adopted.

[0045] Figure 1 This is a flowchart illustrating a video generation method provided in an embodiment of the present disclosure. The embodiments of the present disclosure are applicable to any video production scenario. The method can be executed by a video generation device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, such as a mobile terminal, a PC, or a server.

[0046] like Figure 1 As shown, the method in this embodiment may specifically include:

[0047] S110. Obtain the display parameters of the image to be processed under at least one display metric.

[0048] The display metrics can refer to the animation attributes of an image. For example, display metrics include, but are not limited to, at least one of the following: display position metric, image transparency metric, image scaling metric, image rotation angle metric, and video playback speed metric. Display parameters can refer to the specific numerical values ​​of the animation attributes. It should be noted that display parameters under the same display metric include at least two values ​​to be processed. These at least two values ​​correspond to different video frame positions in the video frame sequence. For example, display parameters under the display position metric include two positions (i.e., values ​​to be processed). One position can be used as the starting point, and the other as the ending point, creating a transition from the starting point to the ending point, forming a video frame position change effect. Alternatively, display parameters under the image transparency metric include two transparency values ​​(i.e., values ​​to be processed). One transparency can be used as the starting point, and the other as the ending point, creating a transition from the starting point to the ending point, forming a video frame transparency change effect.

[0049] Specifically, when creating a video based on an image, that image can be used as a target image. To enable the target image to play as a video according to user requirements, display parameters corresponding to at least one display metric can be determined for the target image. These display parameters can be pre-configured or adjusted by the user to create a video corresponding to the target image based on display parameters under different display metrics.

[0050] It should be noted that when there are at least two images to be processed, each image can be processed separately to generate a video based on each image.

[0051] In this embodiment, when acquiring the display parameters of the image to be processed under at least one display metric, the user can edit the display parameters under at least one display metric. Optionally, in response to the display parameter editing operation of the image to be processed in the video editing interface, at least two display parameters of the image to be processed are acquired.

[0052] In this embodiment, the image to be processed can be displayed on the video editing interface. Users can configure display parameters for the image under at least one display metric based on actual needs or image display effects, thereby obtaining at least two display parameters corresponding to the image to be processed.

[0053] For example, some display parameters can be preset. After importing the image to be processed, two transparency values, such as 5 and 25, can be entered in the display parameters under the image transparency index, indicating that the image changes from transparency 5 to transparency 25; or, two scaling values, such as 70% and 80%, can be entered in the display parameters under the image scaling index, indicating that the image changes from scaling 70% to scaling 80%.

[0054] In this embodiment, when obtaining the display parameters of the image to be processed under at least one display metric, the display parameters corresponding to the target video template can also be retrieved in response to the triggering operation of the target video template. When an editing operation on the display parameters is detected, the updated display parameters can be obtained.

[0055] The target video template includes display parameters such as position, transparency, and rotation information. Different target video templates correspond to different transformed videos.

[0056] In this embodiment, users can select a template that meets their needs based on the video template display effect; the selected template is the target video template. Then, pre-cached display parameters corresponding to the target video template are obtained. Users can adjust these display parameters, for example, changing the transparency of point A from 5 to 25, and then updating it from 5 to 45, to create a video based on the adjusted display parameters.

[0057] The advantage of using the above method to determine display parameters is that users can select a template that meets their needs based on the video template display effect and obtain the display parameters. They can also adjust the display parameters according to actual needs and only update the adjusted display parameters. This improves the convenience of determining display parameters while meeting the needs of users' video production.

[0058] S120. Based on the display parameters and the preset video playback duration, determine at least one target display function associated with the image to be processed.

[0059] The video playback duration can refer to the total length of the video to be created. For example, the video playback duration can be 1 second or 2 seconds, which can be set by the user according to actual needs without specific limitations. The target display function can be used to characterize the transformation process from the first display parameter to the last display parameter under the same display metric. Different target display functions correspond to different display metrics, and the number of target display functions is related to the number of display metrics. That is, there is a corresponding target display function for each display metric.

[0060] In this embodiment, the method for determining the target display function associated with each display metric is the same. For a given display metric, a Bézier curve can be calculated based on at least two display parameters corresponding to that metric and the video playback duration to obtain the target display function associated with that metric. This target display function describes how the image to be processed is displayed at each playback timestamp within the video playback duration. Accordingly, the target display function associated with the image to be processed under each display metric can be obtained.

[0061] S130. When the video display conditions are met, the target playback parameters of the image to be processed at at least one playback timestamp within the video playback duration are determined based on at least one target display function.

[0062] Here, video display conditions refer to the conditions used to determine whether or not to display the video. Each playback timestamp can be considered a point in time within the video playback duration. During video playback, each frame has a timestamp, indicating the playback time of that frame within the video. Target playback parameters can refer to the playback attribute information of the image. Target playback parameters include display position parameters, transparency parameters, rotation angle parameters, and / or video playback speed parameters.

[0063] In this embodiment, video display conditions can be pre-configured. For example, a video display condition could be triggered by a video display control. For instance, when a user clicks the video share button on the interface, it is considered that the video display condition has been met; or, when a user clicks the video creation button on the interface, it can also be considered that the video display condition has been met. Furthermore, the target playback parameters of the image to be processed under one or more playback timestamps within the video playback duration can be determined through the target display function corresponding to each display metric. For example, the target display function contains a correspondence between each input value and a unique output value. The input value is considered a playback timestamp, and the unique output value corresponding to the playback timestamp is the target playback parameter corresponding to that playback timestamp, which is also the target playback parameter of the image to be processed under that playback timestamp.

[0064] S140. Play the image to be processed based on the target playback parameters and generate the target video.

[0065] In this embodiment, the images to be processed can be processed and played sequentially using the target playback parameters corresponding to each playback timestamp according to the temporal relationship of the playback timestamps. The continuous playback of images with multiple timestamps forms a video, which is the target video.

[0066] It should be noted that during video playback, before reaching each playback timestamp, the image to be processed can be used with the target playback parameters corresponding to that timestamp before playback. The processing method for the image to be processed is the same for all images; any of the playback timestamps can be used as the current timestamp. The following explanation uses the processing of the image based on the target playback parameters corresponding to the current timestamp as an example.

[0067] In this embodiment, playing the image to be processed based on the target playback parameters and generating the target video includes: adjusting the image to be processed according to the target playback parameters of the current timestamp to obtain a video frame corresponding to the current timestamp; and generating the target video based on the video frames generated at least one playback timestamp within the video playback duration.

[0068] Specifically, the target playback parameters for the current timestamp can be used to adjust the image to be processed. The adjusted image is then used as a video frame corresponding to the current timestamp. Consequently, the video frame corresponding to each playback timestamp can be obtained. Furthermore, based on the temporal relationship of all playback timestamps, the video frames corresponding to each playback timestamp can be played sequentially, continuously playing the video frames to form the target video.

[0069] For example, assuming the target playback parameters for the current timestamp include: point coordinates (1,1), transparency (25), scaling size (80%), and video speed (1.5), then the point position, transparency, and image scaling size in the image to be processed can be adjusted according to these target playback parameters, and the video speed of the image to be processed at the current timestamp can be adjusted to play the adjusted video frames.

[0070] The technical solution of this disclosure, when producing a video, can first obtain the display parameters of the image to be processed under at least one display metric. Then, based on the display parameters and a pre-set video playback duration, at least one target display function associated with the image to be processed is determined. When the video display conditions are met, based on the at least one target display function, the target playback parameters of the image to be processed under at least one playback timestamp within the video playback duration are determined. Thus, the image to be processed is played based on the target playback parameters, and the target video is generated. This solves the problem of poor video playback effect in the prior art when using interpolation algorithms or Bézier curves to produce videos. It achieves the precise control of the playback parameters under each playback timestamp by combining the display parameters of the image to be processed under at least one display metric and the video playback duration. The target display function represents the target playback parameters of the image to be processed under each playback timestamp within the video playback duration, thereby ensuring the smoothness and stability of video playback, making the video playback more natural, and improving the user experience.

[0071] Figure 2 This is a flowchart illustrating a video generation method provided in an embodiment of this disclosure. Based on the foregoing embodiments, the display parameters under at least one display metric include at least two values ​​to be processed. Accordingly, the statement "determine at least one target display function associated with the image to be processed based on the display parameters and a pre-set video playback duration" can be further refined. For detailed implementation methods, please refer to the detailed description of the embodiments of this disclosure. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here.

[0072] like Figure 2 As shown, the method in this embodiment may specifically include:

[0073] S210. Obtain the display parameters of the image to be processed under at least one display metric.

[0074] S220. For at least one display indicator, based on the two unprocessed values ​​under the display indicator and the control point determination information, determine at least two control point information corresponding to the display indicator.

[0075] The control point determination information can be pre-set attribute information for control points, which are points on the Bézier curve and can be determined by the user. It should be noted that the two pending values ​​under the displayed indicator represent the starting point and the ending point, respectively, requiring a transformation from the starting point to the ending point. For an example, see [link to example]. Figure 3 The black dots pointed to by the arrows on the left and right sides represent the values ​​to be processed, and the remaining black dots in the middle represent control points.

[0076] In this embodiment, control point determination information under the display indicator is obtained. Then, based on the two unprocessed values ​​under the display indicator, the control point determination information can be normalized to adjust the control point determination information to a preset range (such as the range of 0 to 1). The normalized control point determination information can be used as control point information. For example, if the control point determination information is the coordinate position of a point within 0-2s as (1.5, 1.5), (1.5, 1.5) can be normalized to represent the coordinate position of the point within 0-1s as (0.75, 0.75).

[0077] S230. Based on the two unprocessed values ​​corresponding to the display indicators, at least two control point information, video playback duration, and a preset third-order Bézier curve, determine the target display function corresponding to the display indicators.

[0078] The target display function is the function obtained after determining the coefficients of the preset third-order Bézier curve.

[0079] In this embodiment, two values ​​to be processed corresponding to the display index, at least two control point information, and video playback duration can be input into a preset third-order Bézier curve. The coefficients in the preset third-order Bézier curve are calculated, and the Bézier function after determining the coefficients is used as the target display function.

[0080] For example, see Figure 4Users can edit the attribute information of all points (including two values ​​to be processed and at least two control point information) on the client side. This attribute information can then be stored in a library and combined with a third-order Bézier curve to generate the target display function. A third-order Bézier curve is a smooth curve. It is typically defined by four points: two endpoints (e.g., P0 and P3) and two control points (e.g., P1 and P2). Endpoints P0 and P3 are the start and end points of the curve, respectively, while the shape of the curve is controlled by the positions of control points P1 and P2. For example, a third-order Bézier curve can be represented as: B(t) = (1-t) 3 P0+3(1-t) 2 tP1+3(1-t)t 2 P2+t 3 P3; where B(t) represents a point on the Bézier curve (the horizontal axis of the point represents the timestamp, and the vertical axis represents the display parameter), t is the parameter (0≤t≤1), P0 and P3 are the start and end points of the curve, and P1 and P2 are the control points of the curve.

[0081] S240. When the video display conditions are met, based on at least one target display function, determine the target playback parameters of the image to be processed at at least one playback timestamp within the video playback duration.

[0082] S250: Play the image to be processed based on the target playback parameters and generate the target video.

[0083] The technical solution of this disclosure embodiment determines the position of control points in the Bézier curve by user control, allowing users to freely move these points to achieve their desired animation effects. Simultaneously, normalization of the control point determination information ensures data consistency and guarantees the accuracy of video production. Furthermore, based on two unprocessed values ​​corresponding to the display metric, at least two control point information points, video playback duration, and a preset third-order Bézier curve, a target display function corresponding to the display metric is determined. This target display function describes the transformation curve from the first unprocessed value to the second unprocessed value, ensuring the smoothness and stability of the transition.

[0084] Figure 5 This is a flowchart illustrating a video generation method provided in an embodiment of this disclosure. Based on the foregoing embodiments, the display parameters under the display indicators include at least three values ​​to be processed. Accordingly, the statement "determine at least one target display function associated with the image to be processed based on the display parameters and a pre-set video playback duration" can be further refined. For detailed implementation methods, please refer to the detailed description of the embodiments of this disclosure. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here.

[0085] like Figure 5 As shown, the method in this embodiment may specifically include:

[0086] S310. Obtain the display parameters of the image to be processed under at least one display metric.

[0087] S320. Based on preset conditions, group at least two values ​​to be processed under the displayed indicators to obtain at least one data group.

[0088] The preset conditions can refer to the conditions for grouping numerical values. A data group includes two numerical values ​​to be processed that are adjacent in the editing or display order.

[0089] In this embodiment, grouping conditions can be pre-configured. For example, the preset conditions can be conditions for grouping values ​​according to editing order or display order. In this way, according to the preset conditions, every two values ​​to be processed that are adjacent in editing order under the display indicators can be grouped into a group to obtain at least one data group; or, according to the preset conditions, every two values ​​to be processed that are adjacent in display order under the display indicators can be grouped into a group to obtain at least one data group.

[0090] For example, the display parameters under the display position index include four values ​​to be processed: (0,0), (0.25,0.25), (0.75,0.75), and (1,1). They can be divided into three groups according to the display order: ((0,0),(0.25,0.25)), ((0.25,0.25),(0.75,0.75)), and ((0.75,0.75),(1,1)). Each group is called a data group.

[0091] S330. For at least one data set, based on the two values ​​to be processed in the data set and the control point determination information, determine at least two control point information corresponding to the data set.

[0092] It should be noted that the method for determining the segmented display function corresponding to each data group is the same. We can take the determination of the segmented display function corresponding to any one of the data groups as an example for explanation.

[0093] In this embodiment, the method for determining at least two control point information corresponding to the data group is similar to the method for determining at least two control point information corresponding to the display indicators. Both are for the purpose of normalizing the control point determination information and ensuring data consistency, and will not be elaborated here.

[0094] S340. Based on the two values ​​to be processed associated with the data group, at least two control point information, the image display duration of the image to be processed corresponding to the data group, and the preset third-order Bézier curve, determine the piecewise display function corresponding to the data group.

[0095] The image display duration is the duration parameter in the video playback duration. The piecewise display function is a function obtained after determining the coefficients of a preset third-order Bézier curve. Each piecewise display function is a third-order Bézier function.

[0096] In this embodiment, the image display duration corresponding to a data group can be determined based on the interval between two values ​​to be processed in the data group; alternatively, the image display duration corresponding to each data group can be pre-configured. Further, the two values ​​to be processed in the data group, at least two control point information, and the image display duration of the image to be processed corresponding to the data group can be input into a preset third-order Bézier curve. The third-order Bézier curve between the two values ​​to be processed is solved to obtain the coefficients in the third-order Bézier curve. The third-order Bézier function with determined coefficients is used as the piecewise display function corresponding to the data group. Accordingly, the piecewise display function corresponding to each data group can be obtained, and each piecewise display function is a third-order Bézier function with a continuous second derivative.

[0097] The following is an example of how to determine the coefficients of a preset third-order Bézier curve:

[0098] Given n+1 (e.g., x0, x1, ..., x... n Generate n segments of Bessel function from ) points, with x0 as the starting point and x... n The endpoint is defined as y = a, and the remaining points are intermediate points between the starting point and the endpoint. Two adjacent points form a data set, and n data sets correspond to n segments of Bessel functions. Each segment is a second-order continuous function and a cubic polynomial with four variables. The cubic polynomial is represented as: y = a i +b i x+c i x 2 +d i x 3 (1). Among them, variable a i b i c i and d i These are the coefficients to be determined in the function.

[0099] First, we can define a function S(x)∈C2[a,b], which is a cubic polynomial on each subinterval [xi,xi+1], where a=x0 <x1<...<x n =If b is a given node, then S(x) is called a node x0, x1, ..., xn. n A cubic spline function on [a node x]. If at node x... i Given the function value y i =f(x) i (i = 0, 1, ..., n), then S(x) i )=yi (i = 0, 1, ..., n) holds true.

[0100] Constraints: From the above cubic polynomial (1), we know that there are a total of n segments of function, each function has 4 parameters, for a total of 4n parameters, so 4n equations are needed to solve the problem. Because the function is continuous as a whole, at node x... i The continuity condition should be satisfied at (i = 1, 2, ..., n-1): 3*(n-1). Each (x i y i The condition (n+1) is satisfied, i.e., S(x) i )=y i (i = 0, 1, ..., n).

[0101] The two boundary lines are: S"(x0) = S"(x n ) = 0.

[0102] Furthermore, the three-moment equations can be solved by defining a set of numbers M. i =S"(x i ). Due to S i "(x) is [x]" i x i+1 A cubic polynomial over ], therefore S i "(x) is a condition that satisfies S"(x) i ) = M i and S"(x i+1 ) = M i+1 It is a linear function, therefore S i (x) is also M i and M i+1 The straight line between them: Among them, h i =x i+1 -x i .

[0103] Equation (2) can be obtained by integrating equation (3); Equation (3) is expressed as: Interpolation condition S i (x)=y i and S i (x i+1 )=y i+1 Acting on S i We can determine C and D in equation (3) and obtain equation (4).

[0111] S350. Determine the target display function based on the segmented display function corresponding to at least one data group.

[0112] In this embodiment, the segmented display function corresponding to each data group constitutes the entire target display function. For an example, see below. Figure 3 The curve segment between two adjacent points can be represented as a piecewise display function, and the entire curve segment from the starting point to the end point is called the target display function.

[0113] S360. When the video display conditions are met, based on at least one target display function, determine the target playback parameters of the image to be processed at at least one playback timestamp within the video playback duration.

[0114] S370: Play the image to be processed based on the target playback parameters and generate the target video.

[0115] The technical solution of this disclosure embodiment groups at least two values ​​to be processed under the display index according to preset conditions, and determines at least two control point information corresponding to the data group based on the two values ​​to be processed in the data group and the control point determination information, so as to ensure data consistency. Then, based on the two values ​​to be processed associated with the data group, the at least two control point information, the image display duration of the image to be processed corresponding to the data group, and the preset third-order Bézier curve, a piecewise display function corresponding to the data group is determined, so that each data group corresponds to a piecewise display function, ensuring the smoothness and stability of video frame changes.

[0116] Figure 6 This is a flowchart illustrating a video generation method provided in an embodiment of this disclosure. Based on the foregoing embodiments, the statement "When video display conditions are detected, based on at least one target display function, determine the target playback parameters of the image to be processed at at least one playback timestamp within the video playback duration" can be further refined. For detailed implementation methods, please refer to the detailed description of the embodiments of this disclosure. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here.

[0117] like Figure 6 As shown, the method in this embodiment may specifically include:

[0118] S410. Obtain the display parameters of the image to be processed under at least one display metric.

[0119] S420. Based on the display parameters and the preset video playback duration, determine at least one target display function associated with the image to be processed.

[0120] S430. When the system detects that the editing completion control has been triggered and / or the editing duration has reached the preset editing duration threshold, obtain the current timestamp of the target video.

[0121] Among them, editing time can refer to the duration after editing the display parameters.

[0122] In this embodiment, the video display condition can be triggered by the completion of the editing control and / or the editing duration reaching a preset editing duration threshold. Thus, when the system detects that the user has clicked the completion of the editing control, or that the duration of the editing operation on the display parameters has reached the preset editing duration threshold, it confirms that the video display condition is met. At this point, the first playback timestamp of the target video can be obtained as the current timestamp.

[0123] S440. Substitute the current timestamp into at least one target display function to obtain the target playback parameters corresponding to at least one display indicator at the current timestamp.

[0124] In this embodiment, the current timestamp can be substituted into each target display function, and each target display function can output the target playback parameters corresponding to the display index at the current timestamp, so that the image to be processed can be played at the current timestamp according to each target playback parameter.

[0125] For example, see Figure 7 The timestamp X is input from the client to the target display function, and the output ordinate Y is the target playback parameter corresponding to the timestamp X.

[0126] It should be noted that if there are multiple data groups, the timestamps belonging to the data group need to be input into the segmented display function corresponding to that data group to ensure the accuracy of the target playback parameters.

[0127] In this embodiment, the current timestamp is substituted into at least one target display function to obtain the target playback parameters of at least one display metric under the current timestamp, including: for the target display function of at least one display metric, determining the target segmented display function of the current timestamp under the current display metric; substituting the current timestamp into the target segmented display function to obtain the playback parameters to be merged under the current display metric; and determining the target playback parameters based on the playback parameters to be merged under at least one display metric.

[0128] In this embodiment, after determining the current timestamp, the data group containing the current timestamp and its corresponding segmented display function for the current display metric can be determined, and this segmented display function is used as the target segmented display function. Then, the current timestamp is input into the target segmented display function, and the output value of the target segmented display function is used as the playback parameter to be merged for the current timestamp under the current display metric. The playback parameters to be merged under each display metric can be used as the target playback parameters.

[0129] For example, see [link to previous article] Figure 7 The client inputs a timestamp X, where x is the x-coordinate value. The system calculates which interval x falls within (i.e., the duration of the image display), inputs the result of the segmented display function corresponding to that interval's data set, and returns the Y-value corresponding to x to the client. This Y-value is the target playback parameter. (See also...) Figure 3 , Figure 3 The horizontal axis represents the timestamp, and the vertical axis represents the playback parameters. Each timestamp corresponds to a target playback parameter.

[0130] S450. When playing the image to be processed corresponding to the playback timestamp according to the target playback parameters, obtain the next playback timestamp as the current timestamp.

[0131] In practical applications, after determining the target playback parameters corresponding to at least one display indicator at the current timestamp, the image to be processed can be adjusted according to the target playback parameters, and the adjusted image to be processed can be played at the current timestamp (i.e., the playback timestamp). The next playback timestamp is then used as the current timestamp, and steps S440-S450 are executed again to continuously play images at multiple timestamps and generate the target video.

[0132] S460: Play the image to be processed based on the target playback parameters and generate the target video.

[0133] The technical solution of this disclosure, by detecting that the editing completion control is triggered and / or the editing duration reaches a preset editing duration threshold, obtains the current timestamp of the target video, and then substitutes the current timestamp into at least one target display function to obtain the target playback parameters corresponding to at least one display indicator under the current timestamp. When playing the image to be processed corresponding to the playback timestamp according to the target playback parameters, the next playback timestamp is obtained as the current timestamp, thereby realizing real-time playback of video frames, ensuring the smoothness of video playback, and making the video playback more natural.

[0134] Figure 8 This is a schematic diagram of the structure of a video generation apparatus provided in an embodiment of this disclosure, as shown below. Figure 8 As shown, the device includes: a display parameter acquisition module 510, a target display function determination module 520, a target playback parameter determination module 530, and a target video generation module 540.

[0135] The system includes a display parameter acquisition module 510, used to acquire display parameters of the image to be processed under at least one display metric; a target display function determination module 520, used to determine at least one target display function associated with the image to be processed based on the display parameters and a pre-set video playback duration; a target playback parameter determination module 530, used to determine the target playback parameters of the image to be processed under at least one playback timestamp within the video playback duration based on the at least one target display function when the video display conditions are detected; wherein the number of target display functions is related to the number of display metrics; and a target video generation module 540, used to play the image to be processed based on the target playback parameters and generate a target video.

[0136] The technical solution of this disclosure, when producing a video, can first obtain the display parameters of the image to be processed under at least one display metric. Then, based on the display parameters and a pre-set video playback duration, at least one target display function associated with the image to be processed is determined. When the video display conditions are met, based on the at least one target display function, the target playback parameters of the image to be processed under at least one playback timestamp within the video playback duration are determined. Thus, the image to be processed is played based on the target playback parameters, and the target video is generated. This solves the problem of poor video playback effect in the prior art when using interpolation algorithms or Bézier curves to produce videos. It achieves the precise control of the playback parameters under each playback timestamp by combining the display parameters of the image to be processed under at least one display metric and the video playback duration. The target display function represents the target playback parameters of the image to be processed under each playback timestamp within the video playback duration, thereby ensuring the smoothness and stability of video playback, making the video playback more natural, and improving the user experience.
