Detailed Description
According to the video editing scheme based on subtitle recognition, a user can edit videos like editing documents, delete corresponding video segments while deleting characters, and the video editing method is mainly suitable for live broadcast and port broadcast contents with a large amount of explanation contents. The existing video clipping scheme based on subtitle recognition has the following disadvantages:
1. the operation efficiency is low: after the user deletes a sentence for many times, if the user wants to restore a deleted sentence, the user needs to withdraw the sentence once in order until the sentence is restored.
2. The recovery fragment cannot be accurately selected at one time: the deletion is effective for both deletion operation and subtitle editing operation, and in order to delete a certain deleted content, a user needs to orderly delete all operations such as deletion, subtitle editing and the like before one-time deletion until the deleted content is restored to the sentence, so that all edits made by the user in the process are invalid.
3. The adjusting space is small: the content deleted by the user is not visible.
In view of at least some of the above problems, the following embodiments of the present application are proposed. In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
In some of the flows described in the specification, claims, and above-described figures of the present application, a number of operations are included that occur in a particular order, which operations may be performed out of order or in parallel as they occur herein. The sequence numbers of the operations, e.g., 101, 102, etc., are merely used to distinguish between the various operations, and the sequence numbers themselves do not represent any order of execution. Additionally, the flows may include more or fewer operations, and the operations may be performed sequentially or in parallel. It should be noted that, the descriptions of "first", "second", etc. in this document are used for distinguishing different messages, devices, modules, etc., and do not represent a sequential order, nor limit the types of "first" and "second" to be different. In addition, the embodiments described below are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 shows a flowchart of a video clipping method according to an embodiment of the present application. The execution main body of the method provided in this embodiment may be a client device, such as a mobile phone, a desktop computer, a notebook computer, a tablet computer, an intelligent wearable device, and the like, which is not specifically limited in this embodiment. The client device has installed thereon a computer program product (e.g., a clipping application) that implements the method steps described below, or a functional module added to an existing application that implements the method steps described below, or the like. Specifically, as shown in fig. 1, the method includes:
101. and displaying a plurality of sentences and the clipping operation identifiers corresponding to the sentences respectively.
The audio text synchronous with the video to be clipped comprises the sentences, the sentences are respectively associated with corresponding video segments in the video to be clipped, and the clipping operation identifier represents the type of the clipping operation of the user and is used for assisting the user to randomly delete or restore the video segments associated with the sentences.
102. And restoring the video segments associated with the deleted sentences in response to the restoring operation triggered after the user selects one deleted sentence by referring to the clipping operation identification.
In the foregoing 101, the clip operation identifier has two display icons, which are respectively: a first icon representing that the user has not been pruned and prompting the user that pruning may be performed, and a second icon representing that the user has been pruned and prompting the user that the user may be restored at any time. Correspondingly, the method provided by the embodiment may further include the following steps:
and in response to a recovery operation triggered after a user selects a deleted sentence with reference to the clipping operation identifier, switching and displaying the clipping operation identifier corresponding to the deleted sentence as the first icon from the second icon.
As shown in fig. 2a, 2b and 2c, the first icon may be a graphic icon
The second icon may be in the figure
Of course, the icons may be other than those shown in the drawings, and this embodiment is not particularly limited to this.
In another implementation, the editable operation identifier may not have a specific form, but may correspond to an attribute. For example, the clipping operation identifier has two display attributes, which are: a first attribute representing that the user has not been pruned and prompting the user for pruning, and a second attribute representing that the user has been pruned and prompting the user for recovery at any time. The display modes corresponding to the attributes are different, so that the sentences corresponding to the different attributes are displayed in a distinguished manner. For example, the sentence corresponding to the first attribute is displayed normally; and displaying the gray scale corresponding to the statement of the second attribute. Or, the statements corresponding to the first attribute are displayed normally; the sentence corresponding to the second attribute has a strikethrough, such as "hello", displayed thereon. Or, the sentence corresponding to the first attribute is normally displayed; corresponding to the statement with the second attribute, flashing and displaying; and so on. The scheme will be described below with a corresponding embodiment, and the clipping operation identifier is referred to as "clipping operation attribute" hereinafter.
In 102, the recovery operation triggered by the user based on the clipping operation identifier for a pruned statement may be: clicking operation (shown in fig. 2 b) performed by the user on the clip operation identifier with a specific icon form; or the user right clicks on a sentence corresponding to the cutting operation identification without the specific form representing the display attribute and clicks on a corresponding option in the floating window (as shown in fig. 6 b); or the user directly completes the corresponding recovery operation by clicking the corresponding control (such as backspace or enter key) on the keyboard based on the sentence corresponding to the editing operation identifier without the specific form representing and displaying the attribute. Of course, the control on the keyboard may be set manually, and this embodiment does not limit this.
What needs to be added here is: the video clipping refers to the process of performing processing such as segment interception, position arrangement, play speed adjustment, segment connection effect adjustment and the like on a video material to generate a target video. The technical scheme provided by the embodiment relates to the clipping operations such as segment retention, deletion and the like, clips the video through the operations such as deletion, retention, recovery and the like, and does not relate to the position sequencing, the playing speed adjustment, the segment connection effect and the like of the video segments.
According to the technical scheme provided by the embodiment, the cutting operation identifier is displayed for each statement, represents the cutting operation type of the user and is used for assisting the user to randomly delete or recover the video segment associated with the statement; the user can carry out recovery operation on the deleted sentences which are required to be recovered in a targeted manner, the clipping operation is separated from other operations (such as sentence editing), the efficiency of recovering the deleted sentences is high, and the user experience is good.
Further, in this embodiment, the step 101 of displaying the plurality of sentences and the clipping operation identifiers corresponding to the plurality of sentences may include:
1011. sequentially displaying the plurality of sentences according to the playing sequence of the video to be clipped;
1012. and respectively displaying corresponding clipping operation identifications on the corresponding lines of the sentences.
In this embodiment, only the sentence of the audio text may be displayed on the editing interface, and a plurality of sentences may be simultaneously displayed on the interface. The user can browse sentences not displayed on the interface by a slide operation. Or, besides displaying a plurality of sentences on the clipping interface, the video to be clipped can also be displayed and played. That is, in one implementable embodiment, the method may further comprise:
103. displaying a clipping interface; the editing interface comprises a video playing area and a sentence display area for displaying the plurality of sentences;
104. in the video playing area, playing the video to be edited;
105. and determining the plurality of sentences based on the playing progress of the video to be edited.
As shown in the figure, the video playing area and the sentence display area on the clipping interface can be arranged in an up-down distribution manner, for example, an upper part area of the clipping interface is used as the video playing area, and a lower part area is used as the sentence display area. Alternatively, the upper 1/3 area of the clip interface is a video playing area, and the lower 2/3 area is a sentence display area.
Accordingly, the step 1011 "sequentially displaying the sentences in the playing order of the video to be edited" may include:
and in the sentence display area, displaying the sentences adapted to the playing progress and at least one sentence associated with the video clip to be played in the follow-up playing progress in a rolling manner.
Further, the method provided by this embodiment may further include the following steps:
106. determining a sliding track in response to a sliding operation of a user;
107. determining a plurality of sentences to be operated according to the sliding track;
108. and respectively carrying out switching display on the cutting operation identifications corresponding to the sentences to be operated so as to switch from the first icon to the second icon or switch from the second icon to the first icon.
109. And respectively carrying out clipping operation on the video segments associated with the statements to be operated so as to delete or restore the corresponding video segments.
The step 107 may specifically include the following three ways:
and in the first mode, according to the starting position and the ending position of the sliding track, all the sentences marked as the second icons by the cutting operation between the starting position and the ending position are determined to be the plurality of sentences to be operated.
And secondly, determining all sentences marked as first icons by the cutting operation between the starting position and the ending position as the plurality of sentences to be operated according to the starting position and the ending position of the sliding track.
And determining all sentences between the starting position and the ending position as the plurality of sentences to be operated according to the starting position and the ending position of the sliding track.
In the first mode, when step 108 is executed, the clip operation identifier corresponding to each sentence can be switched from the second icon to the first icon in a unified manner, and when step 109 is executed, the video segments associated with each sentence can be recovered in a unified manner.
In the second mode, when step 108 is executed, the clip operation identifier corresponding to each sentence can be switched from the first icon to the second icon in a unified manner, and when step 109 is executed, the video segments associated with each sentence can be deleted in a unified manner.
In the third way, when step 108 is executed, the editing operation identifier corresponding to the first type of statement may be switched from the first icon to the second icon, and the editing operation identifier corresponding to the second type of statement may be switched from the second icon to the first icon (i.e., the opposite operation is performed in a unified manner); wherein, the first category of statements refers to: the statement that the original clip operation identified as the first icon (i.e., not pruned); the second category of statements refers to: the original clip operation is identified as the statement of the second icon (i.e., pruned). And when step 109 is executed, deleting the video segment associated with the first type of statement and restoring the video segment associated with the second type of statement.
Further, the method provided by this embodiment may further include the following steps:
110. performing voice recognition and/or subtitle recognition on the audio synchronized with the video to be clipped to obtain the audio text;
111. responding to the editing operation of a user for one sentence to be modified in the displayed plurality of sentences, and modifying the sentence to be modified based on the editing content of the user;
wherein the modification to the statement comprises at least one of: modifying text content, modifying text style and modifying punctuated sentences.
In addition, the video to be clipped in this embodiment may be a video from a live television program, a video captured by an internet-side video or a video captured by an image capturing device, and the like. In this embodiment, the Speech request may be subjected to Speech recognition by an automatic Speech recognition technology asr (automatic Speech recognition), a Speech recognition technology based on a deep learning technology, and the like, so as to determine text information corresponding to the Speech. And/or performing text Recognition on the image content on the video frames in the video segment, such as performing text Recognition on the image content by using an Optical Character Recognition (OCR) technology.
In this embodiment, the clipping operation and the editing operation are separated, the type of the clipping operation is represented by a clipping operation identifier, and each statement corresponds to one clipping operation identifier. The user refers to the operation identification of the cutting operation to the statement, and only the operation related to the cutting, such as deleting and restoring. Text editing, i.e. an editing operation on a sentence, is independent of a clipping operation. Even if the user deletes the associated video segment by deleting the first sentence, and then performs editing and modifying operations on the fifth sentence, the user performs other editing operations, and the like. If the user wants to restore the deleted first sentence, the user does not need to withdraw the editing and modifying operation of the fifth sentence and other clipping operations performed by the user, and the deleted first sentence can be accurately restored by the technical scheme provided by the embodiment.
Referring to the example shown in fig. 2a, 2b and 2c, after the user imports the video to be edited into the Application (APP), the editing interface of the application has two areas, the area located at the upper part is a video playing area, which is used for playing the video to be edited and displaying the playing progress on the playing progress. The lower area is a sentence display area for displaying a plurality of sentences and the editing operation identifiers 1 corresponding to the sentences. As shown in fig. 2a, when a video to be clipped is imported, before the user does not operate, the clipping operation identifiers 1 corresponding to the respective sentences are all first icons (indicating that the user does not delete and prompting the user that the user can delete). A user triggers a deletion operation on a part of sentences in a plurality of sentences for a plurality of times or once, as shown in fig. 2b, the user operates to delete the second sentence, the third sentence, the fourth sentence, the seventh sentence and the eighth sentence; correspondingly, the video segment associated with the second sentence, the video segment associated with the third sentence, the video segment associated with the fourth sentence, the video segment associated with the seventh sentence and the video segment associated with the eighth sentence are all deleted from the video to be edited. Wherein the second, third and fourth sentences can be deleted at once by the sliding operation mentioned in the present embodiment. For example, the user slides from the second sentence to the fourth sentence, and the second, third, and fourth sentences are deleted at once. Of course, the second, third and fourth sentences may also be deleted in multiple times, which is not specifically limited in this embodiment.
Suppose that the seventh and eighth sentences are deleted first and then the second, third and fourth sentences are deleted. At this time, the user feels that the context continuity is not good after the fourth sentence is deleted, which causes the clipped video to be more obtrusive and wants to withdraw the recovery. By adopting the technical scheme provided by the embodiment, as shown in fig. 2b, the user only needs to click the editing operation identifier corresponding to the fourth sentence, and the deleted fourth sentence can be recovered, as shown in fig. 2 c.

The method provided by this embodiment is that the above-mentioned "clipping operation identifier" is a scheme that has no specific form, but corresponds to an attribute.
The clipping operation attribute in this embodiment may include: a first attribute representing that the user has not been pruned and prompting the user for pruning, and a second attribute representing that the user has been pruned and prompting the user for recovery at any time. There may be different display modes corresponding to different attributes. For example, the clipping operation identifier has two display attributes, which are: a first attribute representing that the user has not been pruned and prompting the user for pruning, and a second attribute representing that the user has been pruned and prompting the user for recovery at any time. The display modes corresponding to the attributes are different, so that the sentences corresponding to the different attributes are displayed in a distinguished manner. For example, the sentence corresponding to the first attribute is displayed normally; and displaying the gray scale corresponding to the statement of the second attribute. Or, the statements corresponding to the first attribute are displayed normally; the sentence corresponding to the second attribute has a strikethrough, such as "hello", displayed thereon. Or, the sentence corresponding to the first attribute is normally displayed; corresponding to the statement with the second attribute, flashing and displaying; and so on.
For example, as shown in fig. 6a, the user selects the second sentence, and then clicks the right button; displaying an operation selection box as shown in fig. 6b on the editing interface, and the user can restore the sentence and restore the video segment associated with the sentence by clicking a 'restore' option in the operation selection box; the operation here can also be cancelled by clicking the "cancel" option in the operation box.

As can be seen from fig. 8, with the solution provided in the embodiment of the present application, the deletion of the sentence and the clipping operation of the video segment are separated from the other two types of operations in the embodiment; even if these types of operations are mixed together, the user can accurately withdraw when the user wants to withdraw a certain operation.
In summary, the embodiment of the present application provides a scheme for unordered recall, and a user can flexibly restore deleted content through the scheme, so that the flexibility and efficiency of editing a video by the user are improved. The following points can be embodied:
1. the operation efficiency is high: after the user deletes the sentence for many times, if the user wants to restore the sentence deleted once, the sentence can be directly restored.
2. Accurate recovery of deleted sentences: when the unordered withdrawal is carried out, a user can directly withdraw a certain deletion operation, and the deletion operation is separated from the editing operation and other adding operations.
3. The adjusting space is large: the deleted content of the user is still visible, and the user can flexibly restore, delete and preview the content in real time again.
