[0079] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0080] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein. Obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0081] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner. Furthermore, in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0082] When multiple video editing tools' effects need to be layered, the common practice in existing technology is as follows: first, process the original video using one of the video editing tools, obtain the processing result from that tool, then input the result into the next video editing tool, and so on. Once all video editing tools have processed the video, a video with the combined effects of multiple tools is obtained. However, since only one video with all the effects is ultimately retained, if a user wants to undo a particular effect, they must sequentially reprocess the original video using the corresponding video editing tools for the desired effect. This lack of convenience and speed hinders the efficiency of video editing.

[0083] This application provides a video editing method. Referring to FIG1, the video editing method includes the following steps:

[0084] S101, Receive the first video editing operation and the second video editing operation.

[0085] The first video editing operation and the second video editing operation are used to trigger the editing of the first video based on the first video editing algorithm and the second video editing algorithm in sequence.

[0086] The video editing operations in this application embodiment can be one or more of the following: clicking operations on controls of video editing functions such as flicker removal controls, reverse playback controls, frame interpolation controls, and noise reduction controls in the video editing interface, video trimming interface, etc.; voice commands; or specific gestures. In some embodiments, the specific gesture can be any one of the following: single-click gesture, swipe gesture, pressure recognition gesture, long-press gesture, area change gesture, double-press gesture, and double-tap gesture.

[0087] For example, referring to FIG2, in some embodiments, the video editing page 200 includes: a first control 21 for adding original video, a second control 22 for selecting the start and end positions of the first video, and a plurality of editing algorithm controls 23 for selecting video editing algorithms; the user can add the original video to be processed by operating the first control 21, and specify the start and end positions by dragging the second control 22 to specify the first video. When the user's operation on at least two editing algorithm controls 23 is received in sequence, it is determined that a video editing operation for triggering the editing of the first video based on the video editing algorithms corresponding to at least two editing algorithm controls 23 has been received.

[0088] It should be noted that, compared to related technologies that require waiting for the previous video processing tool or video editing algorithm to complete the video editing before the next video editing operation can be input when multiple video editing tools are superimposed, the embodiments of this application support users to continuously input multiple video editing operations on the original video. The video editor then edits the element video one by one according to the multiple video editing operations. Therefore, the embodiments of this application can avoid interrupting the user's input of video editing operations, thereby improving the user experience.

[0089] S102. Create a video storage queue.

[0090] That is, for the first video, create a data storage queue for storing the video editing results of different video editing algorithms.

[0091] In some embodiments, after the video storage queue is created, the first video may be saved to the video storage queue first.

[0092] S103. Edit the first video based on the first video editing algorithm to obtain the second video, and save the second video to the video storage queue.

[0093] The first video editing algorithm in this application embodiment can be any video editing algorithm, and this application embodiment does not limit it. For example, the first video editing algorithm can be a flicker removal algorithm, a beautification algorithm, a special effects addition algorithm, etc.

[0094] S104. Edit the second video based on the second video editing algorithm to obtain the third video, and save the third video to the video storage queue.

[0095] Referring to FIG3, in some embodiments, after the first video is edited sequentially based on the first video editing algorithm and the second video editing algorithm, the video storage queue 300 may include: the first video 31, the second video 32 and the third video 33.

[0096] In some embodiments, the video editor may read the second video from the video storage queue and then edit the second video based on the second video editing algorithm.

[0097] In other embodiments, the video editor may read the second video from the terminal device's cache and then edit the second video based on the second video editing algorithm.

[0098] The video editing method provided in this application, upon receiving a first video editing operation and a second video editing operation that trigger sequential editing of a first video based on a first video editing algorithm and a second video editing algorithm, firstly creates a video storage queue, then edits the first video based on the first video editing algorithm to obtain a second video, and saves the second video to the video storage queue; and then edits the second video based on the second video editing algorithm to obtain a third video, and saves the third video to the video storage queue. Because the video editing method provided in this application can create a video storage queue to store the video editing results of different video editing algorithms during video editing, and save the video editing results of different video editing algorithms to this video storage queue, this application can directly read the video editing results from the video storage queue when it is necessary to undo some video editing operations, without having to re-edit the original video every time video editing is undone. Therefore, this application can improve the efficiency of video editing.

[0099] Referring to Figure 4, based on the embodiment shown in Figure 1, the video editing method provided in this application further includes the following steps:

[0100] S401, Receive third video editing operation.

[0101] The third video editing operation is used to trigger the undoing of the second video editing operation.

[0102] That is, the video editing result corresponding to the third video editing operation is the video editing result obtained by editing the first video based solely on the first video editing algorithm.

[0103] S402. In response to the third video editing operation, read the second video from the video storage queue to obtain the video editing result corresponding to the third video editing operation.

[0104] Compared to re-editing the first video based on the first video editing operation to obtain the video editing result corresponding to the third video editing operation, the embodiments of this application can directly read the second video from the video storage queue as the video editing result corresponding to the third video editing operation. Therefore, the above embodiments can improve the video editing efficiency.

[0105] Referring to Figure 5, based on the embodiment shown in Figure 1, the video editing method provided in this application further includes the following steps:

[0106] S501, Receive the fourth video editing operation.

[0107] The fourth video editing operation is used to trigger the cancellation of the first video editing operation.

[0108] That is, the video editing result corresponding to the fourth video editing operation is the video editing result obtained by editing the first video based solely on the second video editing algorithm.

[0109] S502. In response to the fourth video editing operation, the first video is edited based on the second video editing algorithm to obtain the fourth video, and the fourth video is saved to the video storage queue.

[0110] Since the video storage queue does not include the video editing result obtained by editing the first video solely based on the second video editing algorithm, this embodiment of the application edits the first video based on the second video editing algorithm to obtain the video editing result obtained by editing the first video solely based on the second video editing algorithm, and saves it to the video storage queue for use in subsequent video editing processes.

[0111] Referring to Figure 6, based on the embodiment shown in Figure 1, the video editing method provided in this application further includes the following steps:

[0112] S601, Receive the fifth video editing operation.

[0113] The fifth video editing operation is used to trigger the editing of the second video based on the third video editing algorithm.

[0114] That is, the video editing result corresponding to the fifth video editing operation is the video editing result obtained by editing the first video sequentially based on the first video editing algorithm, the second video editing algorithm, and the third video editing algorithm.

[0115] S602. In response to the fifth video editing operation, read the second video from the video storage queue, edit the second video based on the third video editing algorithm to obtain the fifth video, and save the fifth video to the video storage queue.

[0116] In some embodiments, step S103 (editing the first video based on the first video editing algorithm to obtain the second video, and saving the second video to the video storage queue) includes:

[0117] Based on the first video editing algorithm, the video frames of the first video are edited one by one to obtain the corresponding video frames of the second video, and the video frames of the second video are saved to the video storage queue respectively.

[0118] Step S104 (editing the second video based on the second video editing algorithm to obtain the third video, and saving the third video to the video storage queue) includes:

[0119] When the video storage queue contains video frames to be edited, the video frames to be edited are edited based on the second video editing algorithm to obtain the corresponding video frames of the third video, and the video frames of the third video are saved to the video storage queue respectively.

[0120] The video frame to be edited is a video frame in the video storage queue of the second video that has not been edited based on the second video editing algorithm.

[0121] It should be noted that when the first video editing algorithm edits the first video frame by frame, it processes the video frames in the first video in any order. For example, when the first video editing algorithm is used to reverse the video, it can start processing the video frames one by one from the end of the first video. As another example, when the first video editing algorithm is used to deblur the video, it can start processing the video frames one by one from the beginning of the first video.

[0122] For example, referring to FIG7, based on the above embodiment, the implementation process of editing the first video sequentially based on the first video editing algorithm and the second video editing algorithm in the video editing method provided in this application includes: First, reading and processing each video frame of the first video 31 by the first video editing tool 71, and writing the video frames of the second video 32 obtained by processing each video frame of the first video 31 based on the first video editing algorithm into the video storage queue 300. The second video editing tool 72 determines whether the video storage queue 300 includes video frames of the second video that have not been edited based on the second video editing algorithm. If not, it waits for the first video editing tool 71 to write new video frames of the second video into the video storage queue 300. If yes, it reads the video frames of the second video that have not been edited based on the second video editing algorithm from the video storage queue 300, and edits the video frames read based on the second video editing algorithm. Then, it writes the video frames of the third video 43 obtained by processing each video frame of the second video 32 based on the second video editing algorithm into the video storage queue 300.

[0123] Since the video frames of the first video can be edited based on the first video editing algorithm, the resulting video frames of the second video can be written into the video storage queue. Moreover, when the video storage queue includes video frames of the second video that have not been edited based on the second video editing algorithm, the editing of the video frames to be edited based on the second video editing algorithm can begin. Therefore, the above embodiment does not need to wait for the first video editing algorithm to complete the editing of all video frames of the first video before performing video editing through the second video editing algorithm. Thus, the embodiment of this application can reduce the editing time of video editing, thereby improving the user experience.

[0124] In some embodiments, the video editing method provided above further includes naming the second video and the third video by performing the following steps:

[0125] Step a: Generate a video ID based on the video content of the first video and the first algorithm.

[0126] In some embodiments, the first algorithm is a hash algorithm. That is, the video content of the first video is calculated using a hash algorithm, and the calculation result is used as the video ID of the original video.

[0127] That is, Video ID = hash(First Video)

[0128] If the draft video obtained from editing uses an absolute path, the filenames of the draft video and the original video may be duplicated. In order to distinguish them, this application embodiment calculates a hash value based on the video content to generate a video ID, and uses this video ID to replace the original video name as part of the naming parameters.

[0129] Step b: Combine the video ID and the configuration parameters of the first video editing algorithm to obtain the first combined value.

[0130] For example, the configuration parameters of a video editing algorithm may include: the type of algorithm used by the video editing algorithm, speed information, and other configuration parameters.

[0131] Let the first stitching value be defined as stitching value_1, and the configuration parameter of the first video editing algorithm be defined as info_1. Then: Stitching value_1 = Video ID + info_1

[0132] Step c: Obtain the first product ID based on the first splicing value and the second algorithm.

[0133] In some embodiments, the second algorithm is a hash algorithm.

[0134] If we define the first product ID as ID_1, then we have: ID_1 = hash(video ID + info_1)

[0135] Step d: Combine the product ID of the second video and the configuration parameters of the second video editing algorithm to obtain the second splicing value.

[0136] Let the second stitching value be defined as stitching value_2, and the configuration parameter of the second video editing algorithm be defined as info_2. Then we have: Stitching value_2 = ID_1 + info_2

[0137] Step e: Obtain the second product ID based on the second splicing value and the second algorithm.

[0138] If we define the ID of the second product as ID_2, then we have: ID_2 = hash(ID_1 + info_2)

[0139] Step f: Name the second video and the third video according to the first product ID and the second product ID, respectively.

[0140] In some embodiments, the second video and the third video are named according to the first product ID and the second product ID, respectively, including:

[0141] The second video is named according to the first product ID, the start timestamp of the second video, and the duration of the second video;

[0142] The third video is named according to the second product ID, the start timestamp of the third video, and the duration of the third video.

[0143] For example, if the second video is in MP4 format, its start timestamp is 02:16, and its duration is 05:30, then the name of the second video could be:

[0144] First Product ID_02:16_05:30.mp4.

[0145] It should be noted that the naming method for the video obtained by further editing the third video based on the video editing algorithm is similar to the naming method for the third video. For example, referring to Figure 8, Figure 8 illustrates the implementation method of naming the products of video editing algorithms based on video editing algorithm A, video editing algorithm B, and video editing algorithm C in sequence. The implementation process of obtaining the names of the video editing results corresponding to video editing algorithm A, video editing algorithm B, and video editing algorithm C includes:

[0146] S81. Perform hash calculation on the video content of the first video to generate a video ID.

[0147] S82. Combine the video ID with the configuration parameters (info_a) of video editing algorithm A to obtain the splicing value corresponding to video editing algorithm A, and perform hash calculation on the splicing value corresponding to video editing algorithm A to generate the product ID (ID_a) of video editing algorithm A.

[0148] S83. Obtain the splicing value corresponding to video editing algorithm B by combining the product ID of video editing algorithm A with the configuration parameters (info_b) of video editing algorithm B, and perform hash calculation on the splicing value corresponding to video editing algorithm B to generate the product ID (ID_b) of video editing algorithm B.

[0149] S84. Obtain the splicing value corresponding to video editing algorithm C by combining the product ID of video editing algorithm B with the configuration parameters (info_c) of video editing algorithm C, and perform hash calculation on the splicing value corresponding to video editing algorithm C to generate the product ID (ID_c) of video editing algorithm C.

[0150] Finally, the names of the video editing results corresponding to video editing algorithms A, B, and C are obtained based on the product IDs of video editing algorithm A, B, and C, respectively.

[0151] Based on the video editing method provided in the above embodiments, the video editing method provided in this application embodiment may further include the following steps ① to ⑥:

[0152] Step ①: Receive the sixth and seventh video editing operations.

[0153] The sixth video editing operation and the seventh video editing operation are used to trigger the editing of the sixth video sequentially based on the first video editing algorithm and the second video editing algorithm; the sixth video and the first video are different video segments that overlap in the same video.

[0154] The overlap between the first video and the sixth video means that the start and / or end point of the first video clip is located between the start and end points of the sixth video clip.

[0155] Step 2: Based on the start and end points of the first video and the start and end points of the sixth video, obtain the segments in the sixth video that belong to the first video and the segments in the sixth video that do not belong to the first video that need to be edited.

[0156] For example, referring to FIG9, the starting point of the first video 91 is S1, the ending point of the first video 91 is E1, the starting point of the sixth video 92 is S2, the ending point of the sixth video 92 is E2, the segment to be spliced ​​in the sixth video 92 that belongs to the first video 91 is video segment 93 (starting point S2, ending point E1), and the segment to be edited in the sixth video 92 that does not belong to the first video 91 is video segment 94 (starting point E1, ending point E2).

[0157] For example, referring to FIG10, the starting point of the first video 101 is S1, the ending point of the first video 101 is E1, the starting point of the sixth video 102 is S2, the ending point of the sixth video 102 is E2, the segment to be spliced ​​in the sixth video 102 that belongs to the first video 101 is video segment 103 (starting point S1, ending point E1), and the segments to be edited in the sixth video 102 that do not belong to the first video 101 include video segment 104 (starting point S2, ending point S1) and video segment 105 (starting point E1, ending point E2).

[0158] Step 3: Read the third video from the video storage queue.

[0159] Step 4: Extract the video editing results corresponding to the segment to be spliced ​​from the third video.

[0160] That is, the video editing result corresponding to the segment to be spliced ​​is cropped from the third video according to the start and end points of the segment to be spliced.

[0161] As illustrated in the example in Figure 9, step ④ involves cutting out video segment 93 from the third video as the video editing result corresponding to the segment to be spliced.

[0162] Step 5: Edit the segment to be edited sequentially based on the first video editing algorithm and the second video editing algorithm to obtain the video editing result corresponding to the segment to be edited.

[0163] As illustrated in the example shown in Figure 10, step ⑤ involves processing video segment 104 and video segment 105 sequentially based on the first video editing algorithm and the second video editing algorithm.

[0164] Step 6: Combine the video editing results corresponding to the segment to be combined and the video editing results corresponding to the segment to be edited to obtain the video editing result corresponding to the seventh video editing operation.

[0165] In the above embodiment, when obtaining the video editing result corresponding to the seventh video editing operation, the starting and ending points of the first video clip and the starting and ending points of the sixth video are used to obtain the segments to be spliced ​​that belong to the first video and the segments to be edited that do not belong to the first video in the sixth video. Then, the video editing result corresponding to the segments to be spliced ​​is extracted from the third video, and the segments to be edited are processed sequentially based on the first video editing algorithm and the second video editing algorithm to obtain the video editing result corresponding to the segments to be edited. Finally, the video editing result corresponding to the segments to be spliced ​​and the video editing result corresponding to the segments to be edited are spliced ​​together to obtain the video editing result corresponding to the seventh video editing operation. Therefore, the above embodiment can avoid repeatedly processing video segments, thereby further improving the efficiency of video editing.

[0166] Based on the video editing method provided in the above embodiments, the video editing method provided in this application embodiment may further include the following steps 1 and 2:

[0167] Step 1: Receive the eighth and ninth video editing operations.

[0168] The first video editing operation and the second video editing operation are used to trigger the editing of the seventh video based on the first video editing algorithm and the second video editing algorithm respectively, wherein the seventh video belongs to the first video.

[0169] In this embodiment of the application, the seventh video belonging to the first video means that the start and end points of the seventh video are both located between the start and end points of the first video.

[0170] Step 2: Crop the third video according to the start and end points of the seventh video to obtain the video editing result corresponding to the ninth video editing operation.

[0171] In other words, when the length of the first video is shortened, the third video can be directly cropped without having to process the new video again.
