The head model in this embodiment is not a head model for a specific user, and cannot reflect personal information of a specific user.
Fig. 2A and 2B illustrate a video processing method flowchart according to an embodiment of the present disclosure, and as shown in fig. 2A and 2B, a video processing method includes: step S201, acquiring at least one text information segment of a video to be processed, wherein each text information segment in the at least one text information segment is a part of text information corresponding to voice information of the video to be processed; and step S201, aiming at any one text information segment in the at least one text information segment, executing the following processing: step S201-1, in response to determining that a first processing instruction for the text information segment is received, determining a related video segment corresponding to the text information segment in the video to be processed, wherein the text information segment corresponds to voice information in the related video segment; and step S201-2, executing the first processing of the relevant video segment corresponding to the text information segment.
Because the text information can intuitively reflect the content displayed in the video, the user can quickly determine the corresponding video segment to be processed in the video to be processed by browsing the text information segment, so that the situation that the user can know the content of each part in the video to be processed only by dragging the video progress bar can be avoided, the video processing efficiency is improved, and the user experience is improved.
Aiming at some videos taking voice content as a main factor, such as live television and the like, the problem that users pay most attention to ensuring accuracy, clearness and smoothness of the voice content in the videos is often solved. According to the scheme, the text information corresponding to the voice information in the video to be processed is used as a clue, and the corresponding relation between the text information segment and the video segment is established, so that the user can automatically and synchronously realize the corresponding processing of the video segment to be processed through the processing of the text information segment, and finally the processed video with smooth voice information can be obtained.
With respect to step S201, according to some embodiments, acquiring at least one text information segment of the video to be processed may include: acquiring text information corresponding to voice information in a video to be processed; and dividing the text information to obtain at least one text information segment. Thereby, at least one text information segment for video processing can be conveniently acquired.
The text information corresponding to the voice information of the video to be processed can be acquired through a voice recognition technology, and can also be manually entered, which is not limited herein.
According to some embodiments, dividing the text information may comprise: identifying at least one stop point in the text information; and dividing the text information based on the at least one stop point. Therefore, the text information can be conveniently divided.
In one embodiment, the pause point may be a semantic break point. Specifically, by performing semantic analysis on the text information, at least one semantic break point in the text information is identified, and the text information is divided at a position corresponding to each semantic break point in the at least one semantic break point. Each text information segment obtained by dividing the text information has complete semantic content. For example, each piece of textual information may be a complete sentence. Thus, the user can perform processing on the video to be processed in units of each sentence in the voice information.
In another embodiment, the pause point may be a time pause point. Each character in the text information has a respective timestamp, and identifying at least one stopping point in the text information may include: and in response to the time difference between a previous time stamp corresponding to a previous character and a next time stamp corresponding to a next character in any two adjacent characters in the text information being larger than a preset threshold value, at least one of the previous time stamp and the next time stamp is taken as a time stop point. Thus, the text information can be divided into positions corresponding to each of the at least one time stop points. So that each text information segment obtained by dividing the text information has coherent voice information. Therefore, the silent paragraphs in the video to be processed can be identified from the video to be processed, and subsequent targeted processing is facilitated.
According to some embodiments, dividing the text information may further comprise: and dividing the text information according to the maximum number of characters which can be contained in each text information segment. Therefore, the length of each text information segment can be limited, and the text information segments can be conveniently displayed.
In one embodiment, the maximum number of characters that can be contained in each segment of text information may be determined based on one or more factors of the size of the display screen, font size, font type, and the like.
According to some embodiments, the at least one text information segment of the acquired video to be processed may be arranged in a sequence in a time sequence on the display screen, and the user may conveniently browse the content of each part of the video to be processed by browsing the sequence formed by the at least one text information segment.
Further, the user may execute step S202 to perform corresponding processing for each of the at least one text information segment of the acquired video to be processed.
With respect to step S201-1, according to some embodiments, the first processing instruction may be issued directly for the text information segment by the user. For example, at least one text information segment has two repeated text information segments, and the user can directly issue the first processing instruction for removing one text information segment.
According to some embodiments, the method may further comprise: after at least one text information segment of a video to be processed is obtained, determining the type corresponding to each text information segment in the at least one text information segment; acquiring a global processing instruction for a video to be processed, wherein the global processing instruction comprises a processing type; and for each text information segment in at least one text information segment, responding to the type corresponding to the text information segment contained in the processing type, and determining that a first processing instruction for the text information segment is received. Batch processing of multiple video segments can thereby be achieved.
According to some embodiments, the processing type includes one or more of silent sentences, verbal sentences, or repeated sentences.
According to some embodiments, for any one of the at least one piece of text information, in response to the absence of characters in the piece of text information, the type to which the piece of text information corresponds is determined to be a silent sentence. Different from the method of determining the silent video segments in the video by adopting the audio amplitude, the silent sentences in the text information are determined by the method to position the silent video segments in the video to be processed, so that the interference of environmental noise on judgment can be avoided, and the judgment accuracy is improved.
According to some embodiments, for any one of the at least one segment of text information, the segment of text information is determined to be a spoken sentence in response to only one or more spoken words (e.g., kay, o, phi, etc.) being included in the segment of text information.
According to some embodiments, for any two temporally adjacent pieces of text information of the at least one piece of text information, in response to the content similarity in the two pieces of text information being above a preset threshold, e.g., the character repetition rate in the two pieces of text information being greater than 60%, determining at least one of the two pieces of text information as a repeat sentence
According to some embodiments, on the basis of determining the type corresponding to each text information segment in at least one text information segment, a shortcut key capable of selecting one or more text information segments of the same type is provided, so that a user can conveniently select the text information segments of the same type at one time through the shortcut key, and the uniform processing on the text information segments of the same type is conveniently executed.
According to some embodiments, determining the relevant video segment corresponding to the text information segment in the video to be processed comprises: determining a first time stamp corresponding to a first character of the text information section and a second time stamp corresponding to a tail character of the text information section; and determining a relevant video segment corresponding to the text information segment in the video to be processed based on the first time stamp and the second time stamp. Thus, it is possible to easily determine the relevant video segment corresponding to the text information segment so that the text information segment corresponds to the speech information in the relevant video segment.
According to some embodiments, the first processing comprises one or more of a removal operation, an insertion operation, a position transformation operation, a muting operation, or an editing operation.
The removing operation may be used to delete the relevant video segment corresponding to the text information segment, the inserting operation may be used to insert another video segment before or after the relevant video segment corresponding to the text information segment, the position transforming operation may be used to adjust the position of the relevant video segment corresponding to the text information segment, the muting operation may set the relevant video segment corresponding to the text information segment to mute, and the editing operation may set a filter or animation, etc. to the relevant video segment corresponding to the text information segment.
On this basis, step S201-2 can be executed, that is, for the first processing instruction of the text information segment, the first processing for the relevant video segment corresponding to the text information segment is executed.
Fig. 3 shows a schematic diagram of a video processing method according to an embodiment of the present disclosure. As shown in fig. 3, in the display pages 310 to 330, a plurality of pieces of text information are arranged in a row on the display page in chronological order below the video to be processed 340 and its progress bar.
In the display page 310, the user selects a first segment of text information in the display page 310, so that the to-be-processed video 340 and the progress bar thereof can be played to a position corresponding to the first segment of text information (i.e. the beginning of the to-be-processed video 340). And displaying an icon representing the removed first processing instruction on the right side of the selected first text information segment, wherein the user can issue a removal processing instruction aiming at the text information segment by operating the icon.
The user may enter the display page 320 by selecting "multiple choice" in the display page 310, in which display page 320 the user may select a number of pieces of text information to be processed at once.
