[0080] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0081] With the rapid development of short video technology, the variety of short video applications has also gradually increased. Users can process videos using these applications, with video splicing being a commonly used technique.

[0082] Video stitching involves combining multiple videos to create a composite video. However, due to inconsistent video resolutions and potentially different video types (including both landscape and portrait videos), the resulting composite video may exhibit issues during previewing, such as some videos being excessively shrunk, enlarged, or filled with black / white borders, severely impacting the user's preview experience.

[0083] The video processing method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, the server responds to a client's processing request for at least two videos, obtaining the video resolution of each video. Based on the video resolutions of each video, the server determines the maximum resolution and the aspect ratio of each video. Based on the maximum resolution and the aspect ratio of each video, the server determines the global resolution. Finally, the server processes each video according to the processing request and the global resolution.

[0084] In this context, the server refers to the server that provides processing services for the video to be processed. It can be a standalone server or a server cluster. Specifically, the server can be the server-side device corresponding to the short video application, which can receive processing requests for the video to be processed initiated by the client installed on the client.

[0085] A client is a user-side device used to send processing requests for the video to be processed to the server device. The user-side device is configured with a client application to send the processing request and the corresponding video to be processed to the server. Clients can be smart devices such as mobile phones and computers, or smart wearable devices such as smartwatches and smart bracelets.

[0086] In one embodiment, a video processing method is provided, in which the method is applied to Figure 1 Let's take the server-side as an example to illustrate, such as... Figure 2 As shown, it includes the following steps:

[0087] S201, in response to a processing request for at least two videos to be processed, obtain the video resolution of each video to be processed.

[0088] Here, "video to be processed" refers to the video segment that needs to be processed. "Processing request" refers to a request message sent when there is a need to process two videos to be processed. "Video resolution" refers to the number of pixels contained in a video frame.

[0089] In this embodiment, one possible implementation is that the user sends a processing request for the video to be processed to the server through the client, as follows: Figure 3 As shown, in response to a user's video selection operation via the video selection interface on the client, the selected video is displayed. In response to a processing operation on the selected video, the selected video is designated as the video to be processed, and a processing request carrying the video to be processed is sent to the server. For example, as... Figure 3 As shown, Figure 3 The image shown is the video selection interface. In response to the user's selection of candidate videos displayed in the interface, the selected video is shown. In response to processing operations on the selected video, such as clicking "Next," the client treats the selected video as the video to be processed and sends a processing request containing the video to the server.

[0090] In this embodiment, another optional implementation where the user sends a processing request for the video to be processed to the server via a client is as follows: the client sends the processing request to the server via the client; wherein, the processing request carries the video identifier of the video to be processed. After receiving the processing request, the server retrieves the video to be processed corresponding to the video identifier from the database based on the video identifier.

[0091] In this embodiment, another optional implementation where the user sends a processing request for the video to be processed to the server through the client is as follows: in response to the user's triggering operation on the video processing control, the client obtains the video to be processed from the target area of ​​the application (e.g., the video storage area) and sends a processing request for the video to be processed to the server.

[0092] Optionally, in this embodiment, the processing request can be a video merging request, a video preview request, a video display request, etc.

[0093] In this embodiment, one optional implementation method for the server to obtain the video resolution of each video to be processed is to obtain the video metadata of each video to be processed, and then obtain the video resolution of each video to be processed based on the video metadata.

[0094] Another optional implementation method for the server to obtain the video resolution of each video to be processed in this embodiment is to send the videos to be processed to an intelligent analysis tool, which then outputs the video resolution of each video. The intelligent analysis tool can be a video analysis model.

[0095] In this embodiment, another optional implementation for the server to obtain the video resolution of each video to be processed is as follows: After receiving the video to be processed, the server stores it in the target area. Then, it calls FFmpeg or a related library to parse the video to obtain its video resolution.

[0096] S202, determine the maximum resolution and the aspect ratio of each video to be processed based on the video resolution of each video to be processed.

[0097] The maximum resolution refers to the highest video resolution among all the videos to be processed, for example, 1920*1080. The aspect ratio refers to the ratio of the video's height to its width.

[0098] In this embodiment, one possible implementation for determining the maximum resolution based on the video resolution of each video to be processed is to obtain the video resolution of each video to be processed, sort the video resolutions of each video to be processed, and based on the sorting result, take the video resolution with the largest resolution as the maximum resolution.

[0099] In this embodiment, another optional implementation method for determining the maximum resolution based on the video resolution of each video to be processed is to input the video resolution of each video to be processed into the intelligent analysis model, and then have the intelligent analysis model output the maximum resolution.

[0100] In this embodiment, one possible implementation for determining the aspect ratio of each video to be processed based on its video resolution is as follows: for each video to be processed, the aspect ratio is determined based on the ratio between the resolution in the height direction and the resolution in the width direction.

[0101] In this embodiment, another optional implementation method for determining the aspect ratio of each video to be processed based on its video resolution is to input the video resolution of each video to be processed into the intelligent analysis model, and then have the intelligent analysis model output the aspect ratio of each video to be processed.

[0102] S203, determine the global resolution based on the maximum resolution and the aspect ratio of each video to be processed.

[0103] Global resolution refers to the uniform resolution of the final output video, that is, the video resolution of all videos to be processed.

[0104] As an optional implementation of this application, the maximum resolution and the aspect ratio of each video to be processed are input into a trained neural network model, and the neural network model outputs the global resolution.

[0105] Another optional implementation of this application involves determining the long side resolution and short side resolution based on the maximum resolution. The direction of the long side resolution and the direction of the short side resolution are determined based on the aspect ratio of the video. For example, if the direction of the long side resolution is the height direction and the direction of the short side resolution is the width direction, then the final global resolution is the long side resolution in the height direction and the short side resolution in the width direction.

[0106] It should be noted that if there is only one video to be processed, then the video resolution of that video will be used as the global resolution.

[0107] S204 processes each video to be processed based on the processing request and the global resolution.

[0108] Optionally, in this embodiment, when the processing request is a preview request, each video to be processed is previewed based on the global resolution. The preview order of each video to be processed is the same as the order in which the user selects the videos in the video selection interface.

[0109] The aforementioned video processing method, in response to processing requests for at least two videos to be processed, obtains the video resolution of each video to be processed. Based on the video resolution of each video to be processed, it determines the maximum resolution and the aspect ratio of each video to be processed. Based on the maximum resolution and the aspect ratio of each video to be processed, it determines the global resolution. Based on the processing request and the global resolution, it processes each video to be processed. In this application, when the server receives processing requests for two or more videos to be processed, it obtains the video resolution of each video to be processed. Then, based on the maximum resolution and the aspect ratio of each video to be processed, it determines the global resolution. Based on the processing request and the global resolution, it processes each video to be processed, ensuring that the resolution of the processed videos is the global resolution. This effectively solves the problem in existing technologies where some videos are excessively shrunk, enlarged, or filled with black / white borders when previewing videos to be processed, thus improving the user preview experience.

[0110] In one embodiment, to more accurately determine the resolution of the longest side, such as Figure 4 As shown, one optional implementation of determining the global resolution in S203 based on the maximum resolution and the aspect ratio of each video to be processed includes:

[0111] S401, determine the resolution of the longest side based on the relationship between the maximum resolution and the preset resolution threshold.

[0112] As an optional implementation of this application, the maximum resolution and a preset resolution threshold are input into a trained video analysis model, and the video analysis model outputs the longest side resolution. The video analysis model can be a trained neural network model.

[0113] As another optional implementation of this application, if the maximum resolution is greater than a preset resolution threshold, the first resolution is determined as the longest side resolution. If the maximum resolution is not greater than the preset resolution threshold, the second resolution is determined as the longest resolution.

[0114] In another optional implementation of this application, the number of preset resolution thresholds is two or more. Based on this, the longest side resolution is selected from the candidate resolution values ​​according to the relationship between the maximum resolution and each preset resolution threshold. Specifically, the preset resolution thresholds include a first resolution threshold and a second resolution threshold, wherein the first resolution threshold is greater than the second resolution threshold. When the maximum resolution is greater than the first resolution threshold, the first resolution is selected from the candidate resolutions as the longest side resolution; for example, assuming the first resolution threshold is 720*1280, then the first resolution is 1920. When the maximum resolution is not greater than the first resolution threshold but greater than the second resolution threshold, the second resolution is selected from the candidate resolutions as the longest side resolution; for example, assuming the first resolution threshold is 720*1280 and the second resolution threshold is 540*960, then the second resolution is 1280. When the maximum resolution is not greater than the second resolution threshold, a third resolution is selected from the candidate resolutions as the longest side resolution. For example, assuming the second resolution threshold is 540*960, then the third resolution is 960.

[0115] S402, determine the maximum aspect ratio based on the aspect ratio of each video to be processed.

[0116] Among them, the maximum aspect ratio refers to the largest aspect ratio among all video aspect ratios.

[0117] As an optional implementation of this application, the aspect ratios of each video to be processed are sorted, and the largest aspect ratio is determined based on the sorting result, which is then used as the maximum aspect ratio.

[0118] S403 determines the global resolution based on the maximum aspect ratio and the resolution of the longest side.

[0119] As an optional implementation of this application, the maximum aspect ratio and the resolution of the longest side are input into the video analysis model, and the video analysis model outputs the global resolution.

[0120] Another optional implementation of this application involves determining the global height resolution and global width resolution based on the maximum aspect ratio and the resolution of the longest side. The global height resolution and global width resolution are then used as the global resolution.

[0121] In this embodiment, the longest side resolution is determined based on the relationship between the maximum resolution and a preset resolution threshold. The maximum aspect ratio is determined based on the aspect ratio of each video to be processed. The global resolution is then determined based on the maximum aspect ratio and the longest side resolution. This embodiment improves the accuracy of the determined global resolution, thereby enhancing the preview effect of the processed videos and increasing user satisfaction.

[0122] In one embodiment, to further improve the accuracy of the determined global resolution and optimize the processing effect of each video to be processed, such as... Figure 5 As shown, the optional implementation methods for determining the global resolution based on the maximum aspect ratio, the longest side resolution, and the aspect ratio of each video to be processed include:

[0123] S501, based on the maximum aspect ratio, determine the first target direction corresponding to the resolution of the longest side.

[0124] The first target direction is either the width direction or the height direction.

[0125] As an optional implementation of this application, when the maximum aspect ratio is greater than 1, the first target direction corresponding to the resolution of the longest side is determined as the height direction.

[0126] As another optional implementation of this application, when the maximum aspect ratio is not greater than 1, the first target direction corresponding to the resolution of the longest side is determined as the width direction.

[0127] S502, based on the maximum aspect ratio, the resolution of the longest side, and the first target direction, determine the resolution of the short side in the second target direction.

[0128] The second target direction is different from the first target direction; if the first target direction is the width direction, then the second target direction is the height direction; if the first target direction is the height direction, then the second target direction is the width direction.

[0129] In a first optional implementation of this embodiment, the ratio of the longest side resolution to the maximum aspect ratio is used as the short side resolution. A second target direction is determined based on the first target direction. Optionally, in this embodiment, if the first target direction is the height direction, it is determined whether the maximum aspect ratio is greater than the first ratio (e.g., 16 / 9). If it is not greater, the ratio of the longest side resolution to the maximum aspect ratio is used as the short side resolution; if it is greater, the ratio of the longest side resolution to the first ratio is used as the short side resolution. Optionally, in this embodiment, if the first target direction is the width direction, it is determined whether the maximum aspect ratio is less than the second ratio (e.g., 9 / 16). If it is not less, the ratio of the longest side resolution to the maximum aspect ratio is used as the short side resolution; if it is less, the ratio of the longest side resolution to the second ratio is used as the short side resolution. If the first target direction is the height direction, the second target direction is determined to be the width direction; if the first target direction is the width direction, the second target direction is determined to be the height direction.

[0130] The second optional implementation of this embodiment involves determining the short-side resolution in the second target direction based on the maximum aspect ratio, the longest side resolution, the first target direction, and the aspect ratio of each video to be processed. Specifically, the second target direction is determined based on the maximum aspect ratio. Specifically, if the maximum aspect ratio is greater than 1, the first target direction corresponding to the longest side resolution is determined as the height direction; if the maximum aspect ratio is not greater than 1, the first target direction corresponding to the longest side resolution is determined as the width direction. The short-side resolution of each video to be processed in the second target direction is determined based on the longest side resolution and the aspect ratio of each video to be processed. Specifically, for each video to be processed, the ratio of the longest side resolution to the aspect ratio of that video to be processed is used as the short-side resolution of that video in the second target direction, and so on, until the short-side resolution of all videos to be processed in the second target direction is determined.

[0131] S503 uses the resolution of the longest side in the first target direction and the resolution of the shortest side in the second target direction as the global resolution.

[0132] Based on the first implementation method in step S502 above, the resolution of the longest side in the first target direction and the resolution of the shortest side in the second target direction are used as the global resolution. Assuming the first target direction is the height direction and the resolution of the longest side is 1920; and the second target direction is the width direction and the resolution of the shortest side is 720, then the global resolution is 1920*720.

[0133] Based on the second implementation of step S502 above, for each video to be processed, the resolution of the longest side in the first target direction and the resolution of the shortest side in the second target direction are used as the global resolution of the video to be processed. In this embodiment, each video to be processed has a corresponding global resolution, so that the real scene of the video to be processed can be displayed during preview.

[0134] In this embodiment, a first target direction corresponding to the longest side resolution is determined based on the maximum aspect ratio; wherein, the first target direction is either the width direction or the height direction. The short side resolution in a second target direction is determined based on the maximum aspect ratio, the longest side resolution, and the first target direction; wherein, the second target direction is different from the first target direction. The longest side resolution in the first target direction and the short side resolution in the second target direction are used as the global resolution. Based on this embodiment, the accuracy of the determined global resolution is further improved, ensuring that when previewing each video to be processed based on the global resolution, there will be no excessive scaling, scaling, or excessive black and white borders, thus improving the video processing effect and the video display effect in multi-video scenarios.

[0135] In one embodiment, to better suit real-world application scenarios, such as... Figure 6 As shown, one possible implementation method for processing each video to be processed based on the processing request and the global resolution includes:

[0136] S601, when processing a video merging request, adjusts the video resolution of each video to be processed based on the global resolution.

[0137] As an optional implementation of this application, when the global resolution is the same for all videos to be processed, the video resolution of each video to be processed is adjusted based on the global resolution so that the video resolution of each video to be processed is the global resolution.

[0138] As another optional implementation of this application, if each video to be processed has a corresponding global resolution, the global resolution of each video to be processed is obtained. Based on the global resolution, the video resolution of the video to be processed is adjusted so that the video resolution of the video to be processed is the global resolution.

[0139] S602, merge the adjusted videos to obtain the target video.

[0140] As an optional implementation of this application, the adjusted videos to be processed are merged using a video processing tool to obtain the target video. The video processing tool can be a video processing program or a standalone video processing device.

[0141] Based on the above embodiments, another optional implementation of the video processing method involves detecting blank edges on the video cover frame of the target video. If blank edges are detected, the video cover frame is cropped according to the global resolution and the aspect ratio of the video to be processed corresponding to the video cover frame. One optional implementation involves cropping the video cover frame while maintaining the video aspect ratio until at least one edge is free of blank edges; the resolution of the cropped video cover frame is then adjusted based on the global resolution to match the global resolution. Another optional implementation involves cropping the video cover frame while maintaining the global resolution to obtain a first cover frame. While maintaining the video aspect ratio, the video cover frame is then cropped again to obtain a second cover frame. The blank width of the first and second cover frames is obtained, and the cover frame with the narrowest blank width is selected as the final video cover frame. Another alternative implementation involves obtaining the aspect ratio of the preview window, and cropping the video cover frame based on the global resolution and the aspect ratio of the preview window, so that the cropped video cover frame fills the preview window as much as possible while maintaining the global resolution.

[0142] It should be noted that another optional implementation method for cropping the video cover frame is to crop the video cover frame based on the global resolution. Specifically, while keeping the resolution of the video cover frame at the global resolution, the blank areas of the video cover frame are cropped.

[0143] In this embodiment, when the processing request is a video merging request, the video resolution of each video to be processed is adjusted based on the global resolution. The adjusted videos are then merged to obtain the target video. This ensures that the target video does not exhibit situations where some videos are suddenly excessively shrunk, enlarged, or have excessively wide black / white borders, thus improving the user's browsing experience of the target video.

[0144] In one embodiment, to more accurately determine the maximum resolution, such as Figure 7 As shown, an optional implementation method for determining the maximum resolution based on the video resolution of each video to be processed includes:

[0145] S701, for each video to be processed, determine the resolution quantization value of the video to be processed based on the product of the resolution in the width direction and the resolution in the height direction.

[0146] Optionally, in this embodiment, for each video to be processed, the product of the width resolution and the height resolution of the video to be processed is used as the resolution quantization value of the video to be processed.

[0147] S702 takes the video resolution of the video to be processed, which is pointed to by the largest resolution quantization value, as the maximum resolution.

[0148] Optionally, in this embodiment, each video to be processed is sorted according to the resolution quantization value, and the video resolution of the video to be processed pointed to by the largest resolution quantization value is taken as the maximum resolution.

[0149] In this embodiment, for each video to be processed, a resolution quantization value is determined based on the product of the width and height resolutions of the video. The video resolution pointed to by the largest resolution quantization value is taken as the maximum resolution. This embodiment makes the determined maximum resolution more accurate, thereby improving the video processing effect.

[0150] In one embodiment, a video processing method is provided, in which the method is applied to Figure 1 Let's take the client in the example of this as an example. Figure 8 As shown, it includes the following steps:

[0151] S801 sends a processing request to the server for at least two videos to be processed.

[0152] The processing request is used to instruct the server to obtain the video resolution of each video to be processed, determine the maximum resolution and the aspect ratio of each video to be processed based on the video resolution of each video to be processed, determine the global resolution based on the maximum resolution and the aspect ratio of each video to be processed, and process each video to be processed based on the processing request and the global resolution.

[0153] As an optional implementation of this application, the client can package at least two videos to be processed selected by the user into a processing request and send a processing request for the at least two videos to be processed to the server.

[0154] Another optional implementation of this application embodiment is to display a video selection interface. In response to a selection operation of at least two videos to be processed in the video selection interface, a processing request for the at least two videos to be processed is sent to the server. The video selection interface can be an interactive application's video selection interface, displaying some videos or images uploaded by the user. Optionally, the selection operation in this embodiment can be a response to a user's selection operation of at least two videos to be processed, displaying the selected at least two videos to be processed, and a response to a confirmation control in the video selection interface (e.g., a confirmation button). Figure 3 The triggering operation of the "Next" control shown executes a selection operation on at least two videos to be processed in the video selection interface. Optionally, the selection operation in this embodiment can also be a response to the selection operation on candidate videos in the video selection interface, where the at least two videos to be processed pointed to by the selection operation are used as the selection operation on at least two videos to be processed.

[0155] Optionally, in some embodiments, an optional implementation of a video processing method is to receive a target video sent by a server and, in response to a playback operation for the target video, play the target video based on the global resolution.

[0156] In one embodiment, such as Figure 8 As shown, an optional implementation of a video processing method in this embodiment includes:

[0157] S901, in response to a processing request for at least two videos to be processed, obtains the video resolution of each video to be processed.

[0158] S902, for each video to be processed, determine the resolution quantization value of the video to be processed based on the product of the resolution in the width direction and the resolution in the height direction.

[0159] S903 uses the video resolution of the video to be processed, which is pointed to by the largest resolution quantization value, as the maximum resolution.

[0160] S904: Based on the relationship between the maximum resolution and each preset resolution threshold, select the longest side resolution from the candidate resolution values.

[0161] S905: For each video to be processed, determine the aspect ratio of the video to be processed based on the ratio between the resolution in the height direction and the resolution in the width direction.

[0162] S906: Determine the maximum aspect ratio based on the aspect ratio of each video to be processed.

[0163] S907: When the maximum aspect ratio is greater than 1, the first target direction corresponding to the resolution of the longest side is determined as the height direction; when the maximum aspect ratio is not greater than 1, the first target direction corresponding to the resolution of the longest side is determined as the width direction. The first target direction can be either the width direction or the height direction.

[0164] S908, based on the maximum aspect ratio, the resolution of the longest side, and the first target direction, determine the resolution of the short side in the second target direction. The second target direction is different from the first target direction.

[0165] S909 uses the resolution of the longest side in the first target direction and the resolution of the shortest side in the second target direction as the global resolution.

[0166] S910, when processing a video merging request, adjusts the video resolution of each video to be processed based on the global resolution.

[0167] S911 merges the adjusted videos to obtain the target video.

[0168] S912 performs blank edge detection on the video cover frame of the target video.

[0169] S913, when a blank edge is detected, performs cropping of the video cover frame according to the global resolution and the aspect ratio of the video to be processed corresponding to the video cover frame.

[0170] In this embodiment, in response to processing requests for at least two videos to be processed, the video resolution of each video to be processed is obtained. Based on the video resolution of each video to be processed, the maximum resolution and the aspect ratio of each video to be processed are determined. Based on the maximum resolution and the aspect ratio of each video to be processed, the global resolution is determined. Based on the processing request and the global resolution, each video to be processed is processed. In this application, when the server receives processing requests for two or more videos to be processed, it obtains the video resolution of each video to be processed. Then, based on the maximum resolution and the aspect ratio of each video to be processed, the global resolution is determined. Based on the processing request and the global resolution, each video to be processed is processed so that the resolution of the processed videos is the global resolution. This effectively solves the problem in the prior art where some videos are excessively shrunk, enlarged, or filled with black / white borders when previewing videos to be processed, thus improving the user preview experience.
