[0034] Figure 1 A schematic diagram of an exemplary system architecture to which the video preview method of embodiments of the present disclosure can be applied is shown.

[0035] like Figure 1 As shown, the system architecture may include server 101, network 102, terminal device 103, terminal device 104, and terminal device 105. Network 102 serves as the medium for providing a communication link between terminal device 103, terminal device 104, or terminal device 105 and server 101. Network 102 may include various connection types, such as wired or wireless communication links or fiber optic cables, etc.

[0036] Server 101 can be a server that provides various services, such as a back-end management server that supports the devices operated by users using terminal devices 103, 104, or 105. The back-end management server can analyze and process received requests and other data, and feed back the processing results to terminal devices 103, 104, or 105.

[0037] Terminal devices 103, 104, and 105 can be smartphones, tablets, laptops, desktop computers, smart speakers, wearable smart devices, virtual reality devices, augmented reality devices, etc., but are not limited to these.

[0038] In this embodiment of the disclosure, the terminal device 103 can display a video playback interface, which includes a video playback area. The user can click on the target location that they want to zoom in on. In response to the trigger operation on the target location in the video playback area, the terminal device 103 can display a target outline in the associated area of ​​the target location and display a magnified image of the video image in the target outline on the video playback interface for the user to view.

[0039] It should be understood that Figure 1 The number of terminal devices 103, 104, 105, network 102, and server 101 in the diagram is merely illustrative. Server 101 can be a single physical server, a server cluster consisting of multiple servers, or a cloud server. Depending on actual needs, it can have any number of terminal devices, networks, and servers.

[0040] The following will describe in more detail the various steps of the video preview method in the exemplary embodiments of this disclosure, with reference to the accompanying drawings and examples.

[0041] Figure 2 This is a flowchart illustrating a video preview method according to an exemplary embodiment. Figure 2 The method provided in the embodiments can be executed by any electronic device, such as the one described above. Figure 1 Terminal devices in or Figure 1 The server in, or Figure 1 The terminal devices and servers in the process are executed together, but this disclosure does not limit this.

[0042] like Figure 2 As shown, the method provided in this disclosure embodiment may include the following steps.

[0043] In step S210, a video playback interface is displayed, which includes a video playback area.

[0044] In this embodiment of the disclosure, users can watch videos through the video playback area of ​​the video playback interface of the terminal device. Users can be video reviewers or video viewers. The video playback interface can include a video playback area and other areas. The video playback area displays video images, which can be in a playing state or a paused state. Other areas can display relevant information about the video images, such as a brief introduction or evaluation of the video images.

[0045] refer to Figure 3 The video playback interface 301 may include a video playback area 302, which may occupy the entire screen of the terminal device or be located in a part of the screen of the terminal device; the video playback area 302 displays video images.

[0046] In step S220, in response to a trigger operation targeting a target location in the video playback area, the display area of ​​the target frame in the video playback interface is determined based on the overlap between the associated area of ​​the target location and the video playback area.

[0047] The target location can be any location within the video playback area, such as the location of small text or other video details in a video that the viewer wants to zoom in on; the triggering operation can include, but is not limited to, click operation, swipe operation, long press operation, double click operation, hover operation, voice trigger operation, etc.; the target frame can be a solid line or a dashed line of a preset color, such as a blue frame or a red frame.

[0048] In this embodiment of the disclosure, when a video viewer wants to zoom in on the video image of the area surrounding a target location, they can click or hover the mouse over the target location. In response to the click or hover operation on the target location, the terminal device can determine the display area of ​​the target frame in the video playback interface based on the overlap between the associated area of ​​the target location and the video playback area.

[0049] Specifically, the associated area of ​​the target location can be an area centered on the target location; if the associated area of ​​the target location partially overlaps with the video playback area, the position of the associated area of ​​the target location is adjusted to obtain the display area of ​​the target frame; if the associated area of ​​the target location completely overlaps with the video playback area, the associated area of ​​the target location can be directly used as the display area of ​​the target frame.

[0050] In step S230, the target frame is displayed in the display area, and a magnified image of the video image within the target frame is displayed on the video playback interface.

[0051] In this embodiment of the disclosure, after determining the display area of ​​the target frame, the target frame is displayed in the display area, and a magnified image of the video image in the target frame is displayed at any position on the video playback interface. The magnified image is an image of the video image in the target frame after magnification processing, which makes it easier for the video viewer to view the details of the video image in the target frame.

[0052] Continue to refer to Figure 3For example, a video viewer can click on a target location 303 in the video playback area. In response to the click operation on the target location, the terminal device can determine the display area of ​​the target frame line based on the associated area of ​​the target location 303, display the target frame line 304 in the display area, and display a magnified image 305 of the video image in the target frame line 304 on the video playback interface.

[0053] In this embodiment of the disclosure, the magnified image of the video image within the target frame is consistent with the state of the video image within the target frame; specifically, if the video image within the target frame is in a paused state, the magnified image is an enlarged picture; if the video image within the target frame is in a playback state, the magnified image is a dynamic video image, which is magnified and displayed in real time to show the corresponding video content.

[0054] In this embodiment of the disclosure, the size of the target frame and the area where the magnified image is located can be automatically adapted based on the size of the current video playback area and the position of the video playback area in the video playback interface.

[0055] The video preview method provided in this disclosure responds to a trigger operation targeting a target position in the video playback area of ​​the video playback interface. Based on the overlap between the associated area of ​​the target position and the video playback area, the display area of ​​the target frame in the video playback interface is determined. The resulting target frame can include more video content, facilitating magnification of video content details. Displaying the target frame in the display area prompts the user to zoom in on the video image. Furthermore, a magnified image of the video image within the target frame is automatically displayed on the video playback interface. The method is simple to operate, allowing users to view the details of the video image within the target frame more intuitively and quickly, while also enriching the display format of the video playback interface.

[0056] Furthermore, the video preview method provided in this disclosure can be applied to video review scenarios, allowing video reviewers to quickly zoom in on small review points in the video, saving a significant amount of review time and improving review efficiency.

[0057] In an exemplary embodiment, determining the display area of ​​the target frame line on the video playback interface based on the degree of overlap between the associated area of ​​the target location and the video playback area may include: forming an associated area of ​​the target location centered on the target location; if the associated area of ​​the target location and the video playback area partially overlap, adjusting the position of the associated area of ​​the target location to obtain the display area of ​​the target frame line, wherein at least one side of the display area is aligned with at least one side of the video playback area.

[0058] In this embodiment, the target frame can be a square, and its side length can be set according to the size of the video playback area or preset. When the video viewer clicks on the target location or hovers the mouse over the target location, an associated region of the target frame can be formed with the target location as the center and the set side length. That is, the area around the target location is taken as the associated region. At this time, the associated region may be entirely within the video playback area or may partially overlap with the video playback area. Based on the degree of overlap between the initial display area and the video playback area, the associated region of the target frame is adjusted to determine the display area of ​​the target frame. The display area of ​​the target frame can be entirely within the video playback area, which facilitates magnification of details within the video playback area.

[0059] In this embodiment of the disclosure, if the entire associated area of ​​the target frame is located within the video playback area (refer to...) Figure 3 If the area associated with the target frame contains only video content, then there is no need to adjust the area associated with the target frame; the area associated with the target frame can be directly determined as the display area of ​​the target frame.

[0060] In an exemplary embodiment, determining the display area of ​​the target frame line on the video playback interface based on the degree of overlap between the associated area of ​​the target location and the video playback area may further include: if the associated area of ​​the target location is entirely located within the video playback area, then the associated area of ​​the target location is determined as the actual display area of ​​the target frame line.

[0061] In this embodiment of the disclosure, reference is made to Figure 4 If the associated region 402 of the target position formed by the target position 401 partially overlaps with the video playback area 302, that is, the associated region 402 of the target position only partially includes the video content, then the associated region of the target position needs to be adjusted to make it align with the edge of the video playback area 302; see reference. Figure 5 The diagram shows the associated area of ​​the adjusted target position (i.e. the display area of ​​the target frame). It can be seen that the display area 403 of the target frame and the video playback area 302 are adjacent, that is, at least one edge of the display area 403 of the target frame is aligned with at least one edge of the video playback area 302.

[0062] In this embodiment of the disclosure, when the display area of ​​the target frame and the video playback area partially overlap, the position of the display area of ​​the target frame is adjusted to fit the edge, so that the display area of ​​the target frame is entirely video content, which facilitates the magnification of the video content in the display area.

[0063] In an exemplary embodiment, the target frame is a square; when the shorter side of the video playback area is less than or equal to a preset length, the length of the target frame is equal to the shorter side of the video playback area; when the shorter side of the video playback area is greater than the preset length, the length of the target frame is equal to a preset percentage of the shorter side of the video playback area, wherein the preset percentage is less than 1.

[0064] In this embodiment of the disclosure, the shorter side length of the video playback area can be represented by x. If the video is displayed in landscape mode, the height of the video playback area is x; if the video is displayed in portrait mode, the width of the video playback area is x.

[0065] In this embodiment of the disclosure, when the short side length x of the video playback area is less than or equal to a preset length (e.g., 200px (pixels)), i.e., the video player is a small-sized video player, the side length of the target wireframe is set to x; when the short side length x of the video playback area is greater than the preset length (e.g., 200px), i.e., the video player is a large-sized video player, the side length of the target wireframe is set to a preset percentage of the short side length of the video playback area, e.g., x*y%, i.e., the side length of the target wireframe is y% of the width of the video playback area. If a decimal point appears, it is rounded up to one place.

[0066] In this embodiment of the disclosure, the size of the target frame can be intelligently set according to the size of the video playback area, making it easier for users to view the details of the video image within the target frame.

[0067] In an exemplary embodiment, the video playback interface includes a left area of ​​the video playback area and a right area of ​​the video playback interface.

[0068] refer to Figure 6 The video playback interface 301 includes a left area 601 and a right area 602 of the video playback area 302. Based on the size of the left area 601 and the right area 602, the larger area is selected to display the magnified image.

[0069] In an exemplary embodiment, displaying a magnified image of a video image within a target frame on a video playback interface includes: determining the wider region between the left and right regions as the target region; magnifying the video image within the target frame according to a preset multiple relationship between the width of the target region and the side length of the target frame to obtain a magnified image; and displaying the magnified image within the target region.

[0070] Continue to refer to Figure 6Compare the width of the left region 601 (i.e., the left margin of the video playback area from the left side of the screen) and the width of the right region 602 (i.e., the right margin of the video playback area from the right side of the screen). Taking the larger width of the right region 602 as an example, the right region 602 is used as the target region, and the magnified image is displayed in the right region 602.

[0071] In this embodiment of the disclosure, the video image in the target frame is magnified according to a preset multiple relationship between the width of the target area and the side length of the target frame. The preset multiple can be a pre-set magnification multiple, such as 2.5 times. By comparing the preset multiple relationship between the width of the target area and the side length of the target frame, it is determined whether the target area can display a magnified image with a side length that is a preset multiple of the side length of the target frame, so as to facilitate the magnification of the video image in the target frame.

[0072] In an exemplary embodiment, the video image within the target frame is magnified to obtain a magnified image based on a preset multiple of the width of the target region and the side length of the target frame. This includes: if the width of the target region is greater than or equal to a preset multiple of the side length of the target frame, the video image within the target frame is magnified by a preset multiple to obtain a magnified image; if the width of the target region is less than a preset multiple of the side length of the target frame, the video image within the target frame is magnified based on the video state of the video image within the target frame to obtain a magnified image.

[0073] Specifically, if the width of the target area is greater than or equal to a preset multiple (e.g., 2.5 times) of the side length of the target frame, it means that the target area can display a magnified image after the video image within the target frame is magnified by 2.5 times. In this case, the video image within the target frame is directly magnified by 2.5 times to obtain the magnified image.

[0074] Specifically, if the width of the target area is less than a preset multiple (e.g., 2.5 times) of the side length of the target frame, it means that the target area cannot fully display the magnified image after the video image within the target frame is magnified by 2.5 times. In this case, the actual magnification factor can be determined based on the width of the target area, and the video image within the target frame can be magnified based on the actual magnification factor (equivalent to filling the target area); or, based on the video status (paused or playing) of the video image within the target frame, the video image within the target frame can be magnified to obtain the magnified image.

[0075] In this embodiment of the disclosure, in addition to considering a preset multiple of the side length of the target frame, a preset distance between the magnified image and the video playback area can also be considered. For example, if the preset distance between the magnified image and the video playback area is 20px, then the relationship between the difference between the width of the target area and the preset distance (y-20px) and the preset multiple of the side length of the target frame (2.5x) is determined. If the difference between the width of the target area and the preset distance (y-20px) is greater than or equal to the preset multiple of the side length of the target frame (2.5x), then the video image in the target frame is magnified by the preset multiple to obtain a magnified image. If the difference between the width of the target area and the preset distance (y-20px) is less than the preset multiple of the side length of the target frame (2.5x), then the video image in the target frame is magnified according to the video state of the video image in the target frame to obtain a magnified image.

[0076] In this embodiment of the disclosure, the relationship between the width of the target area and the preset multiple of the side length of the target frame can be intelligently determined, and the video image in the target frame can be adaptively magnified.

[0077] In this embodiment of the disclosure, the video playback area can be extended left and right to obtain the display area of ​​the magnified image, and the magnified image and the display area of ​​the magnified image can be aligned, that is, at least one side of the magnified image and at least one side of the display area of ​​the magnified image are aligned.

[0078] refer to Figure 7 The video playback area 302 is extended to the left and right to obtain the magnified image display area 701. The magnified image 305 and the magnified image display area 701 are aligned to make it easier for users to view the details in the magnified image.

[0079] In an exemplary embodiment, the video image within the target frame is magnified according to its video state to obtain a magnified image. This includes: if the video image within the target frame is in playback mode, the video image within the target frame is magnified by a preset factor and then cropped to obtain a magnified image; if the video image within the target frame is in paused mode, color index analysis is performed on the video image within the target frame; if the color index of the video image within the target frame is greater than or equal to a preset factor, the video image within the target frame is magnified by a preset factor and then cropped to obtain a magnified image; if the color index of the video image within the target frame is less than a preset factor, a target factor is determined based on the width of the target region and the side length of the target frame, and the video image within the target frame is magnified by the target factor to obtain a magnified image.

[0080] In this embodiment of the disclosure, color index analysis of a video image may be performed on color gradation analysis of the video image; determining whether the color index of the video image within the target frame is greater than or equal to a preset index may be determined by determining whether the number of primary color gradations in the video image within the target frame is greater than or equal to a preset number; determining whether the color index of the video image within the target frame is less than a preset index may be determined by determining whether the number of primary color gradations in the video image within the target frame is less than a preset number.

[0081] Specifically, if the width of the target area is less than a preset multiple (e.g., 2.5 times) of the side length of the target frame and the video image in the target frame is in playback mode, then the video image in the target frame is enlarged by a preset multiple and then cropped so that the enlarged image obtained after cropping can be displayed in the target area.

[0082] Specifically, if the width of the target area is less than a preset multiple (e.g., 2.5 times) of the side length of the target frame and the video image within the target frame is in a paused state, and the number of main color levels in the video image within the target frame obtained after color level analysis is greater than or equal to a preset number (e.g., 3), it indicates that the video image within the target frame has rich colors and needs to be magnified by a preset multiple. In this case, the video image within the target frame is magnified by a preset multiple and then cropped so that the magnified image obtained after cropping can be displayed within the target area.

[0083] Specifically, if the width of the target area is less than a preset multiple (e.g., 2.5 times) of the side length of the target frame, and the video image within the target frame is in a paused state, and the number of main color levels in the video image within the target frame obtained after color level analysis is less than a preset number (e.g., 3), it indicates that the video image within the target frame has simple colors and does not need to be magnified by a preset multiple. Therefore, a target multiple (e.g., less than 2.5 times) is determined based on the width of the target area and the side length of the target frame, and the video image within the target frame is magnified by the target multiple to obtain a magnified image, which can be displayed within the target area.

[0084] In this embodiment of the disclosure, based on the relationship between the width of the target area and the side length of the target frame, the video status of the video image in the target frame, and the analysis results of the color index analysis of the video image in the target frame, the video image in the target frame is intelligently magnified so that the magnified image can be displayed in the target area, making it convenient for users to view the specific details in the magnified image.

[0085] It should also be understood that the above is only to help those skilled in the art better understand the embodiments of this disclosure, and is not intended to limit the scope of the embodiments of this disclosure. Those skilled in the art can obviously make various equivalent modifications or changes based on the examples given above.
