[0020] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure.

[0024] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0025] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0026] In order to solve the above problems, the embodiments of the present disclosure provide a method for generating and processing a dynamic image, in which a plurality of video clips are cropped according to a preset dynamic image ratio to ensure that the video frame ratios of the cropped video clips are consistent. Thus, all the cropped video clips are merged to generate a dynamic image, which will not cause a sudden change in the video frame ratio, thereby improving the dynamic image display effect. Moreover, by cropping video clips to generate a dynamic image, not only the computing power consumption of the dynamic image generation is reduced, but also the video content contained in the dynamic image is streamlined, which is conducive to highlighting the expression object of the dynamic image.

[0027] The following describes the method for generating and processing a dynamic image in conjunction with a specific embodiment.

[0028] Figure 1 The present invention provides a flowchart of a method for generating and processing a dynamic image, which can be executed by a dynamic image generation and processing device, wherein the device can be implemented by software and / or hardware, and can generally be integrated in an electronic device. Figure 1 As shown, the method includes:

[0029] Step 101: Acquire multiple video clips corresponding to at least one video source.

[0030] When at least one video source is multiple, the multiple video sources may be from one video or multiple videos, etc. In this embodiment, multiple video clips corresponding to at least one video source are obtained, wherein the multiple video clips are multiple video clips required to generate a dynamic image.

[0031] It should be noted that in different application scenarios, the methods for obtaining multiple video clips corresponding to at least one video source are different, and examples are as follows:

[0032] In some possible examples, multiple video clips actively uploaded by the user may be obtained.

[0033] In some possible examples, in response to obtaining the intercepted time period corresponding to each video source, the intercepted time period may be one or more, and each intercepted time period corresponds to a video clip. The intercepted time period may be input by the user, or may be marked by the user when watching the video source. The video source may also be input into a pre-trained deep learning model, and the deep learning model may output the corresponding intercepted time period. The method of determining the video source may be different in different application scenarios. For example, the video source identifier input by the user may be obtained, and the video source may be determined by querying a preset video library based on the video source identifier. For example, a video retrieval keyword may be obtained, and the video source may be determined in a preset video library based on the video retrieval keyword.

[0034] In this example, after the capture time period is determined, a video segment matching the corresponding capture time period is cut out from each video source to obtain a plurality of video segments corresponding to at least one video source.

[0035] For example, Figure 2 As shown, if the video source includes video A and video B, if the interception time period of video A is 14s-16s, 44s-46s, then the video segment A1 corresponding to 14s-16s in video A and the video segment A2 corresponding to 44s-46s in video A are cut out, and if the interception time period of video B is 29s-31s, 89s-91s, then the video segment B1 corresponding to 29s-31s in video B and the video segment B2 corresponding to 89s-91s in video B are cut out. In this example, a moving picture is generated according to the video segments A1, A2, B1, and B2.

[0036] In the actual execution process, if the above-mentioned video source is an online resource, then in order to realize the cropping of the video source, the video source may not be downloaded as a whole, but the video source may be regarded as a combination of multiple video segments according to time periods. For example, for a video source C with a duration of 58 minutes, one video segment is formed every 6 minutes, which can be divided into 10 video segments, and the duration of the last video segment is 4 minutes. In one embodiment of the present disclosure, multiple segment time periods corresponding to the preset multiple video segments contained in each video source are obtained, and the intercepted time period is matched with the segmented time period of each video segment respectively to determine the successfully matched video segment. Taking the above example as an example, if the intercepted time period corresponding to the video source C is 60-65 seconds, the first video segment is hit; when the intercepted time period is 598 seconds-604 seconds, the first and second video segments are hit at the same time.

[0037] After determining the successfully matched video segments, the successfully matched video segments are downloaded, and the video segments matching the corresponding interception time period are intercepted from the successfully matched video segments. Thus, in this example, only the successfully matched video segments need to be downloaded, which reduces the consumption of download resources.

[0038] Step 102, determining target cropping frame position information corresponding to each video clip, wherein the cropping frame ratio corresponding to each target cropping frame position information is the same as the predetermined target animated image ratio.

[0039] The cropping frame ratio corresponding to the target cropping frame position information is the same as the predetermined target dynamic image ratio. For example, the cropping frame ratio corresponding to the target cropping frame position information is the same as the predetermined target dynamic image ratio, which is 16:9.

[0040] In one embodiment of the present disclosure, target cropping frame position information corresponding to each video clip is determined, wherein the target cropping frame position information is used to limit the cropping area of ​​the target cropping frame in the video frame, etc. For example, if the target cropping frame position information is (30,30,640,360), then the cropping area corresponding to the target cropping frame position information is: an area with a size of 640*360 and a center point at the position (30,30) of the video frame.

[0041] Step 103 , cropping each video frame in the corresponding video segment according to the target cropping frame position information to obtain a cropped video segment.

[0042] After determining the target cropping frame position information, each video frame in the corresponding video segment is cropped according to the target cropping frame position information to obtain the cropped video segment. Therefore, the video frame ratio of each cropped video segment is the target dynamic image ratio, ensuring the consistency of the size ratio when the dynamic image is subsequently synthesized.

[0043] In some possible embodiments, a target cropping area that matches the target cropping frame position information can be determined in each video frame, and the video frames within the target cropping area can be cropped, that is, the area outside the target cropping area is discarded and only the area within the target cropping area is cropped.

[0044] In some possible embodiments, in order to further highlight the object of the animated image, the target video object contained in the first frame of each video segment can be determined based on the target cropping frame position information, and in subsequent video frames of the video segment, the area where the target video object is located in each video frame is identified, and the area where the target video object is located is cropped based on the size information of the target cropping frame corresponding to the target cropping frame position information.

[0045] Step 104: merge all the cropped video clips to generate a moving picture.

[0046] In this embodiment, all the cropped video clips are merged to generate a dynamic image, wherein the video frame ratios of the video frames included in the dynamic image are completely consistent, thereby improving the display effect of the dynamic image. In one embodiment of the present disclosure, a dynamic image format for generating a dynamic image can be obtained, and the dynamic image format can be any one of webp, gif, and avif, and the cropped video clips are used to generate a dynamic image according to the corresponding dynamic image format.

[0047] In some possible embodiments, in order to further improve the display effect of the animated image, the size of the animated image that matches the target animated image ratio can also be determined, that is, the video frame ratios of each video frame in the cropped video clip are consistent, but it is also possible that the sizes of different video frames are inconsistent. In this case, all the cropped video frames can be adjusted to the size of the animated image, and the adjusted video clips can be merged to generate the animated image. As a result, all the video frames included in the animated image not only have the same image ratio, but also the same size, which further improves the display effect of the animated image.

[0048] In different application scenarios, the methods for adjusting all cropped video clips to the size of animated images are different, as shown in the following examples:

[0049] In some possible examples, it can be identified whether the size of all cropped video clips is consistent with the size of the animated image. If not, the inconsistent cropped video clips are determined. If the inconsistent cropped video clips are smaller than the corresponding animated image size, the video frames in the inconsistent cropped video clips are filled, and the size of the filled video frames is consistent with the size of the animated image. The filling processing method can be filling pixel points with predetermined pixel values ​​around the video frame, etc., wherein the predetermined pixel value can be the pixel value with the most pixel points in the current video frame to be filled, etc., thereby improving the display effect of the filled video frame; in this example, if the inconsistent cropped video clips are smaller than the corresponding animated image size, the video frames in the inconsistent cropped video clips are thumbnailed, and the corresponding video frames are downsampled to the size of the animated image, etc.

[0050] In summary, the method for generating and processing a dynamic image in the disclosed embodiment obtains multiple video clips corresponding to at least one video source, determines the target cropping frame position information corresponding to each video clip, wherein the cropping frame ratio corresponding to each target cropping frame position information is the same as the predetermined target dynamic image ratio, and then, each video frame in the corresponding video clip is cropped according to the target cropping frame position information to obtain a cropped video clip, and all cropped video clips are merged to generate a dynamic image. In this technical solution, the video frame ratios of all video frames contained in the dynamic image are guaranteed to be consistent, which improves the dynamic image display effect, and the corresponding video frames are cropped before the dynamic image is synthesized, which reduces the computing power consumption of the dynamic image synthesis, and is conducive to highlighting the object expressed by the dynamic image.

[0051] Based on the above embodiments, in order to further facilitate the dynamic image generation process, the dynamic image generation process of the embodiment of the present disclosure can also be performed in a visual manner. That is, in one embodiment of the present disclosure, a preset cropping interface can be pre-set to provide related functions of video frame cropping on the preset cropping interface.

[0052] Among them, the display function of the preset cropping interface can be set according to the scene requirements. As a possible implementation method, Figure 3 As shown, the preset cropping interface includes a video clip capture area, a dynamic image ratio setting area, a cropping effect preview area, etc.

[0053] The video clip capture area may provide functions related to capturing video clips. After capturing video clips, identification information of multiple captured video clips may be displayed in the video clip capture area (the corresponding identification information is represented in text form in the figure); the animation ratio setting area may include multiple cropping indicator boxes corresponding to multiple candidate animation ratios. The multiple candidate animation ratios in the figure include 16:9, 3:2, and 3:4. The cropping effect preview area may display cropping indicator boxes and cropped video frames, for example, Figure 4 As shown, when the cropped video frame is video frame Q, the video frame Q and the corresponding cropping frame can be displayed in the cropping effect preview area. In this example, in order to locate the position information of the cropping frame, rightward and downward are the positive directions of the X and Y axes respectively, with the upper left corner of Q as the origin, and the width and height W and H of the cropping frame, so that the specific position information of the cropped frame on Q can be identified.

[0054] In conjunction with the above-mentioned visualized preset cropping interface, the following specifically describes how to determine the target cropping frame position information corresponding to each video segment.

[0055] Reference Figure 5 , determining the target cropping frame position information corresponding to each video segment includes:

[0056] Step 501: Display multiple cropping indication boxes corresponding to multiple candidate animation ratios on a preset cropping interface, and display a reference video frame of the current video segment to be cropped on the preset cropping interface.

[0057] The reference video frame may be the first video frame of the video segment to be cropped, or any video frame selected by the user and belonging to the video segment to be cropped, etc. The reference video frame of the current video segment to be cropped is displayed on the preset cropping interface.

[0058] In this embodiment, a plurality of cropping indication boxes corresponding to a plurality of candidate animation ratios are displayed on the preset cropping interface, for example, Figure 3 As shown, cropping indicator frames corresponding to 16:9, 3:2 and 3:4 are displayed respectively. A reference video frame is displayed in the cropping effect preview area on the preset cropping interface.

[0059] Step 502 : in response to obtaining a selection operation of a target cropping indication frame corresponding to a target animation ratio among a plurality of candidate animation ratios, displaying the target cropping indication frame in a reference video frame.

[0060] In this embodiment, in response to obtaining a selection operation of a target cropping indication box corresponding to a target animation ratio among multiple candidate animation ratios, the target cropping indication box is displayed in a reference video frame, that is, the corresponding target cropping indication box is displayed in the reference video frame to facilitate the user to operate the target cropping indication box.

[0061] Step 503 : in response to acquiring a drag operation on the target cropping indication frame, determining a cropping area within the target cropping indication frame in the reference video frame.

[0062] In this embodiment, in response to acquiring a drag operation on the target cropping indication frame, a cropping area within the target cropping indication frame is determined in the reference video frame, that is, the user drags the target cropping indication frame to circle the cropping area.

[0063] Of course, in the actual implementation process, the user can also scale the target cropping indicator box when dragging the target cropping indicator box. For example, when the target cropping indicator box is 16:9, if the initial size is 1920*800, it can be reduced to 640*360 through scaling operations. If the user drags the reduced target cropping indicator box to the position (30,30) of the reference image frame, the target cropping indicator box position information corresponding to the target cropping indicator box is determined to be (30,30,640,360).

[0064] Step 504: determine the relative position information of the cropping area in the target cropping indication frame in the reference video frame, and determine the relative position information as the target cropping frame position information.

[0065] In this embodiment, the relative position information of the cropping area in the target cropping indication frame in the reference video frame is determined as the target cropping frame position information, which includes the relative coordinate position information of the target cropping frame in the reference video frame.

[0066] In some possible embodiments, a display parameter setting area for the video clip may also be displayed on the preset cropping interface, such as Figure 3 As shown, the display parameter setting area includes at least one display parameter setting control, and the user can set the corresponding reference display parameter based on a triggering operation on the display parameter setting control.

[0067] The reference display parameters that can be set include playback speed, contrast, brightness, etc. The playback speed can include a multiple speed value, etc.

[0068] In one embodiment of the present disclosure, in response to obtaining reference display parameters corresponding to the current video clip set on a preset cropping interface, image processing is performed on the cropped current video clip according to the reference display parameters, wherein the actual display parameters of the current video clip after image processing are consistent with the reference display parameters, that is, after synthesizing the animated image and before synthesizing the cropped video segment, it is also necessary to adjust display parameters such as contrast and brightness, and then, perform transcoding operations on the video segment to obtain the corresponding animated image.

[0069] In summary, the dynamic image generation processing method of the embodiment of the present disclosure can determine the position information of the target cropping frame in a visual manner, etc., thereby improving the intuitiveness of video segment cropping and the interactivity of dynamic image synthesis.
