Detailed Description
The video clipping scheme based on subtitle identification enables a user to edit a video like editing a document, and delete corresponding video clips while deleting characters, and is mainly suitable for live broadcast and oral broadcast contents with a large amount of explanation contents. The existing video clip scheme based on subtitle recognition has the following defects:
1. The operation efficiency is low: after the user deletes the sentences for a plurality of times, if the user wants to recover the sentences deleted for a certain time, the user needs to withdraw the sentences sequentially once until recovering the sentences.
2. Failure to recover fragments one accurate selection: the revocation is effective for both the deletion operation and the subtitle editing operation, and the user needs to sequentially delete all the deletion operations, subtitle editing operations and the like before one revocation in order to revoke the deleted content for a certain time until the sentence is restored, so that the editing done by the user in the process is totally invalid.
3. The adjustment space is small: the content deleted by the user is not visible.
In view of at least some of the problems described above, the following examples of the present application are presented. In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.
In some of the flows described in the specification, claims, and drawings described above, a plurality of operations occurring in a particular order are included, and the operations may be performed out of order or concurrently with respect to the order in which they occur. The sequence numbers of operations such as 101, 102, etc. are merely used to distinguish between the various operations, and the sequence numbers themselves do not represent any order of execution. In addition, 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" and "second" herein are used to distinguish different messages, devices, modules, etc., and do not represent a sequence, and are not limited to the "first" and the "second" being different types. Furthermore, the embodiments described below are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Fig. 1 is a schematic flow chart of a video editing method according to an embodiment of the present application. The execution subject 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, etc., which is not limited in this embodiment. The client device is provided with a computer program product (such as a clipping application) capable of realizing the following method steps, or a functional module added in the existing application capable of realizing the following method steps, etc. Specifically, as shown in fig. 1, the method includes:
101. and displaying the clipping operation identifiers corresponding to the multiple sentences respectively.
The audio text synchronized with the video to be clipped comprises a plurality of sentences, the sentences are respectively associated with corresponding video clips in the video to be clipped, and the clipping operation identification represents the clipping operation type of the user and is used for assisting the user to randomly delete or restore the video clips associated with the sentences.
102. In response to a restoration operation triggered by a user selecting a pruned sentence with reference to a clipping operation identification, restoring a video segment associated with the pruned sentence.
In the above 101, the clipping operation identifier has two kinds of presentation icons, which are respectively: a first icon indicating that the user has not pruned and prompting the user to make a pruning and a second icon indicating that the user has pruned and prompting the user to resume at any time. Correspondingly, the method provided by the embodiment may further include the following steps:
and responding to a recovery operation triggered after the user selects a deleted sentence with reference to the clip operation identification, and displaying the clip operation identification corresponding to the deleted sentence as the first icon by switching the second icon.
As shown in figures 2a, 2b and 2c, the first icon may be in the figureThe second icon may be +_ in the figure>Of course, other icons than those shown in the drawings are also possible, and the present embodiment is not limited in detail.
In another implementation solution, the manipulable operation identifier may not have a specific form, but a corresponding attribute. For example, the clipping operation identifier has two presentation properties, namely: a first attribute indicating that the user has not pruned and prompting the user to prune and a second attribute indicating that the user has pruned and prompting the user to recover at any time. The display modes corresponding to the attributes are different, so that sentences corresponding to the different attributes are displayed differently. For example, a sentence corresponding to the first attribute is normally displayed; and displaying gray scale corresponding to the sentence of the second attribute. Or, the sentence corresponding to the first attribute is normally displayed; sentences corresponding to the second attribute have strikethroughs displayed thereon, such as "hello". Or, the sentence corresponding to the first attribute is normally displayed; a sentence corresponding to the second attribute is displayed in a flashing manner; etc. This scheme will be described below with respect to the embodiments, and the clip operation identifier will be referred to as "clip operation attribute" hereinafter.
In 102 above, the recovery operation for a pruned sentence triggered by the user based on the clipping operation identification may be: clicking operation (shown in fig. 2 b) performed by the user on the clip operation identifier with the specific icon form; or the user performs right click on the corresponding sentence based on the clipping operation identification of the characterization display attribute without the specific form and clicks the corresponding option in the floating window (as shown in fig. 6 b); or the user directly completes corresponding recovery operation by clicking corresponding controls (such as a backspace or an enter key and the like) on the keyboard based on sentences corresponding to the clipping operation identifiers of the characterization display attributes without concrete forms. Of course, the controls on the keyboard may be manually set, the present embodiment is not limited thereto.
What is needed here is that: the video clipping refers to the process of generating a target video by performing processing such as segment interception, position arrangement, play speed adjustment, segment engagement effect adjustment and the like on video materials. The technical solution provided in this embodiment relates to clip operations such as clip retention, deletion, etc., by which video is clipped, the video clip position ordering, play speed adjustment, clip connection effect and the like are not involved.
According to the technical scheme provided by the embodiment, the clipping operation identifiers are displayed for each sentence, and the clipping operation identifiers represent the clipping operation types of the users and are used for assisting the users to randomly delete or recover video clips associated with the sentences; the user can pertinently restore the deleted sentences which are wanted to be restored, the editing operation is separated from other operations (such as sentence editing), the efficiency of restoring the deleted sentences is high, and the user experience is good.
Further, in the embodiment, the step 101 of displaying the plurality of sentences and the clipping operation identifiers corresponding to the plurality of sentences respectively may include:
1011. sequentially displaying the sentences according to the playing sequence of the video to be clipped;
1012. and respectively displaying the corresponding clipping operation identifiers on the corresponding rows of the plurality of sentences.
In this embodiment, only sentences of audio text may be displayed on the clipping interface, and a plurality of sentences may be displayed on the interface at the same time. The user can browse sentences not displayed on the interface by a slide operation. Or, besides a plurality of sentences, the editing interface can display and play the video to be edited. That is, in one possible embodiment, the method may further include:
103. Displaying a clipping interface; the editing interface comprises a video playing area and a sentence displaying area for displaying the sentences;
104. playing the video to be clipped in the video playing area;
105. and determining the sentences based on the playing progress of the video to be clipped.
As shown in the figure, the video playing area and the sentence displaying area on the clip interface may be arranged in a top-bottom manner, for example, a partial area on the clip interface is used as the video playing area, and a lower partial area is used as the sentence displaying area. Or, the area of the upper part 1/3 of the clipping interface is a video playing area, and the area of the lower part 2/3 is a sentence display area.
Accordingly, the step 1011 "sequentially displaying the plurality of sentences according to the playing order of the video to be clipped" may include:
and in the sentence display area, scrolling and displaying at least one sentence associated with the sentence matched with the playing progress and the video clip to be played after the playing progress.
Further, the method provided in 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 switching and displaying the clipping operation identifiers corresponding to the multiple sentences to be operated respectively so as to switch from the first icon to the second icon or from the second icon to the first icon.
109. And respectively performing clipping operation on the video clips related to the multiple sentences to be operated so as to delete or restore the corresponding video clips.
The above step 107 may specifically include the following three ways:
in the first mode, according to the starting position and the ending position of the sliding track, all sentences with the clipping operation identification of the second icon between the starting position and the ending position are determined to be the multiple sentences to be operated.
And secondly, determining all sentences of which the clipping operation mark is a first icon between the starting position and the ending position as the multiple sentences to be operated according to the starting position and the ending position of the sliding track.
And thirdly, determining all sentences between the starting position and the ending position as the multiple sentences to be operated according to the starting position and the ending position of the sliding track.
In the first embodiment, when step 108 is executed, the clip operation identifier corresponding to each sentence is uniformly switched from the second icon to the first icon, and when step 109 is executed, the video clips associated with each sentence are uniformly restored.
In the second embodiment, when step 108 is executed, the clip operation identifier corresponding to each sentence is uniformly switched from the first icon to the second icon, and when step 109 is executed, the video clip associated with each sentence is uniformly deleted.
In the third mode, when executing the step 108, the clip operation identifier corresponding to the first type sentence is switched from the first icon to the second icon, and the clip operation identifier corresponding to the second type sentence is switched from the second icon to the first icon (i.e. the opposite operation is uniformly performed); wherein, the first type of statement refers to: the original clipping operation identifies the sentence as the first icon (i.e., un-pruned); the second type of statement refers to: the original editing operation is identified as the second the sentence of the icon (i.e., pruned). And when step 109 is executed, deleting the video segments associated with the first class of sentences and recovering the video segments associated with the second class of sentences.
Further, the method comprises the steps of, the method provided by the 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 multiple sentences, and modifying the sentence to be modified based on the editing content of the user;
Wherein the modification to the statement includes at least one of: text content modification, text style modification, sentence breaking modification.
In addition, the video to be clipped in the embodiment may be a video from a live television program, a video on the internet side, or a video acquired by an image acquisition device. The present embodiment can determine the text information corresponding to the voice by performing voice recognition on the voice request by using an automatic voice recognition technology ASR (Automatic Speech Recognition), a voice recognition technology based on a deep learning technology, and the like. And/or text recognition of image content on video frames in a video clip, such as by optical character recognition (OCR, optical Character Recognition) techniques.
In this embodiment, the editing operation is separated from the editing operation, the editing operation type is characterized by the editing operation identifier, and each sentence corresponds to one editing operation identifier. The user refers to the clip operation to identify the operation on the sentence, and only the clip-related operation such as deletion, restoration. Text editing, i.e., editing operations on sentences, is independent of the clipping operations. Even if the user deletes the associated video clip by deleting the first sentence, then edits and modifies the fifth sentence, and then performs other clipping operations, etc. If the user wants to recover the deleted first sentence, the user can accurately recover the deleted first sentence without withdrawing the editing and modifying operation on the fifth sentence and other clipping operations performed by the user.
Referring to the examples shown in fig. 2a, 2b and 2c, after a user guides a video to be clipped into an Application (APP), there are two areas on a clip interface of the application, and an area located at the upper part is a video playing area for playing the video to be clipped, and a playing progress is displayed on the playing progress. The area at the lower part is a sentence display area, and the clipping operation identifier 1 is used for displaying a plurality of sentences and corresponding sentences. As shown in fig. 2a, when the video is to be clipped, before the user has not operated, the clipping operation identifier 1 corresponding to each sentence is a first icon (indicating that the user has not pruned and prompting the user to delete). The user triggers the deleting operation on part of the sentences in multiple times or once, as shown in fig. 2b, the second sentence, the third sentence, the fourth sentence, the seventh sentence and the eighth sentence are deleted by the user operation; correspondingly, the video segments associated with the second sentence, the video segments associated with the third sentence, the video segments associated with the fourth sentence, the video segments associated with the seventh sentence and the video segments associated with the eighth sentence are deleted from the video to be clipped. Wherein the second, third and fourth sentences can be deleted at one time 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 be deleted multiple times, which is not particularly limited in this embodiment.
Suppose that the seventh and eighth sentences are deleted first, and then the second, third and fourth sentences deleted later. At this time, the user feels that the context continuity is bad after the fourth sentence is deleted, resulting in some abrupt video editing, which is wanted to withdraw the resume. With the technical solution provided in this embodiment, as shown in fig. 2b, the user may click on the clip operation identifier corresponding to the fourth sentence, so as to delete the fourth sentenceThe recovery is performed and the recovery is performed, as shown in fig. 2 c. In FIG. 2c, the clip operation corresponding to the fourth sentence is identified from the second icon (e.g) Switch display as the first icon (e.g +.>).
