Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure.
Fig. 1 is a flowchart illustrating a subtitle editing method according to an exemplary embodiment, which may be used in a computer device such as a terminal, for example, in a video editing interface displayed by the terminal, as shown in fig. 1, and includes the following steps.
In step S110, in response to a selection operation acting on a preset icon in a subtitle editing interface, taking a subtitle component corresponding to the selected preset icon as a first subtitle component, where each subtitle component in the subtitle editing interface corresponds to a preset icon;
for example, when a user performs video editing through the video editing interface, the subtitle component displayed in the subtitle editing interface is the subtitle component to be added to the video.
In practical applications, at least two subtitle components may be displayed in the subtitle editing interface, each subtitle component in the subtitle editing interface may correspond to a preset icon, for example, a preset icon may be displayed in an end region of each subtitle component, and by responding to a selection operation acting on a preset icon corresponding to a certain subtitle component, the subtitle component corresponding to the selected preset icon may be used as a first subtitle component, and the first subtitle component may be inserted into another subtitle component when merging the subtitle components.
Specifically, by responding to a preset action of the operating medium acting on a preset icon in the subtitle editing interface, a preset I/O interface may be called, and the I/O interface may be used to take a subtitle component corresponding to the selected preset icon as the first subtitle component.
For example, when it is detected that a user long-presses (i.e., performs a preset action) a preset icon at a terminal area of a certain subtitle component using a mouse (i.e., an operating medium), a callback may be triggered, that is, in response to a selection operation, a subtitle component corresponding to the selected preset icon is used as a first subtitle component, and then, in response to an operating medium movement event, a drag function for the first subtitle component may be implemented.
In step S120, moving an action point corresponding to the selected operation, and acquiring positioning information of the action point in the subtitle editing interface in real time;
the action point may be a virtual display corresponding to the operation medium, such as a cursor display of a mouse in a subtitle editing interface.
As an example, the positioning information may be a text information positioning position corresponding to a position where the action point is located in a text region of another subtitle component to be merged, such as a position where a current cursor of a mouse is located at a corresponding character in text information displayed in the text region.
In a specific implementation, the action point corresponding to the selected operation may be moved, for example, a user moves a corresponding cursor using a mouse, so that the first subtitle component implements a dragging function, and may obtain the positioning information of the action point in the subtitle editing interface in real time, for example, a preset I/O interface may be called in the process of moving the action point corresponding to the selected operation, and the I/O interface may be used to obtain the positioning information of the action point in the subtitle editing interface in real time.
In an example, the terminal may recognize that a current cursor of a mouse is positioned at a corresponding character in text information of another subtitle component to be merged based on an application program interface (e.g., field selection start) provided by the subtitle editing application platform.
In step S130, in response to the release operation corresponding to the selection operation, the second subtitle component and the target insertion position are determined based on the newly acquired positioning information, the text information in the first subtitle component is inserted into the target insertion position in the second subtitle component, and a new subtitle component is displayed.
The second caption component can be another caption component to be merged; the text information in the subtitle component may be characters identified from the video to be edited or characters added by the user.
As an example, the target insertion position may be located at a certain character in the text information displayed in the text region of the second subtitle component.
In practical application, in response to a release operation corresponding to the selection operation, the second subtitle component and the target insertion position are determined based on the latest acquired positioning information, and then the text information in the first subtitle component can be inserted into the target insertion position in the second subtitle component to obtain a new subtitle component, and the new subtitle component after the merging processing can be displayed.
Specifically, a preset I/O interface may be invoked by responding to a preset release action corresponding to the selected operation, and the I/O interface may be configured to determine a second subtitle component and a target insertion position based on the latest acquired positioning information, insert text information in the first subtitle component into the target insertion position in the second subtitle component, and display the target insertion position to obtain a new subtitle component.
For example, after it is detected that the user releases the mouse, the operation of pressing the mouse is released, the latest acquired positioning information is determined based on an application program interface provided by the subtitle editing application platform, and then the second subtitle component to be merged and the target insertion position are determined according to the latest acquired positioning information, so that the text information in the first subtitle component and the text information in the second subtitle component are merged by using the target insertion position, and a new merged subtitle component is obtained.
Compared with the traditional method for combining the subtitles by checking and clicking, the technical scheme of the embodiment realizes the subtitle component selection, the subtitle combining position determination and the subtitle component combining processing in one action by the user through the interactive mode of dragging and connecting lines based on the operations of pressing, moving and releasing the mouse, does not need the user to select and click the button, optimizes the operation flow and can support accurate and flexible insertion position detection.
According to the subtitle editing method, the subtitle component corresponding to the selected preset icon is used as the first subtitle component by responding to the selection operation of the preset icon acting on the subtitle editing interface, the preset icon corresponds to each subtitle component in the subtitle editing interface, then the action point corresponding to the selection operation is moved, the positioning information of the action point in the subtitle editing interface is obtained in real time, the release operation corresponding to the selection operation is further responded, the second subtitle component and the target insertion position are determined based on the newly obtained positioning information, the text information in the first subtitle component is inserted into the target insertion position in the second subtitle component, and the new subtitle component is obtained by displaying. Therefore, the subtitle components to be merged and the specific merging position can be quickly positioned on the basis of the selection and movement of the action points of the preset icons, and the efficiency of subtitle merging processing is improved.
In an exemplary embodiment, as shown in fig. 2, after the step of responding to the selection operation of the preset icon in the subtitle editing interface, the following steps may be further included:
in step S210, displaying the selected preset icon as a triggered state;
in a specific implementation, after responding to a selection operation of a preset icon acting in a subtitle editing interface, the terminal may display the selected preset icon in a triggered state, for example, display the preset icon in a designated color to represent that the preset icon is in the triggered state.
In an example, a certain subtitle component area in the subtitle editing interface can be highlighted in response to a click operation acting on the subtitle component area, and then a selection operation can be carried out on a preset icon of the terminal area of the subtitle component to display the preset icon in a triggered state.
In step S220, in the process of moving the action point corresponding to the selection operation, the movement track indication of the action point is displayed with the preset icon in the triggered state as a starting point.
After the preset icon is displayed in the triggered state, in the process of moving the action point corresponding to the selected operation, the movement track indication of the action point may be displayed by using the preset icon in the triggered state as a starting point, for example, by using the preset icon in the triggered state as a starting point, the movement track indication corresponding to the action point is constructed in a linear manner.
According to the technical scheme, the selected preset icon is displayed as the triggered state, and then in the action point process corresponding to the mobile selection operation, the preset icon in the triggered state is used as the starting point to display the moving track indication of the action point, the moving track indication in the action point moving process can be displayed as the triggered state based on the preset icon, and the visualization effect in the subtitle merging process is improved.
In an exemplary embodiment, displaying the selected preset icon as a triggered state includes: displaying the selected preset icon as a first preset color; the first preset color is different from a display color of the unselected preset icons.
As an example, the first preset color may be red to enhance the display of the preset icon in the triggered state.
In practical application, a first preset color corresponding to the triggered state may be preset, and then the selected preset icon may be displayed as the first preset color, where the first preset color may be different from a display color of the unselected preset icon to represent that the preset icon is in the triggered state.
According to the technical scheme of the embodiment, the selected preset icon is displayed in the first preset color, and the first preset color is different from the display color of the unselected preset icon, so that the preset icon can be highlighted in the triggered state, and the triggered subtitle merging function can be represented conveniently.
In an exemplary embodiment, in the process of moving the action point corresponding to the selected operation, taking a preset icon in a triggered state as a starting point, displaying a movement track indication of the action point, includes: displaying a straight line segment with a second preset color as a moving track indication in the process of moving the action point corresponding to the selected operation; the straight line segment takes the preset icon in the triggered state as a starting point and takes the real-time position of the action point in the subtitle editing interface as an end point.
As an example, the second predetermined color may be red to enhance the display of the movement trace indication of the action point.
In practical application, in the process of moving the action point corresponding to the selection operation, a straight line segment of a second preset color is displayed as a moving track indication, the straight line segment takes the preset icon in the triggered state as a starting point, and takes the real-time position of the action point in the subtitle editing interface as an end point, for example, a red straight line segment from the preset icon to the current real-time position of the action point.
Specifically, in the subtitle editing interface, when the mouse is moved, a dragging effect may be exhibited with a line as an association between a preset icon at the end of the selected subtitle component (i.e., the first subtitle component) and the current cursor position of the mouse.
According to the technical scheme, in the action point process corresponding to the mobile selection operation, the linear line segment with the second preset color is displayed to serve as the mobile track indication, the linear line segment takes the preset icon in the triggered state as the starting point and the real-time position of the action point in the subtitle editing interface as the terminal point, the quick positioning can be carried out based on the mobile track indication, the visual display effect is achieved, and the efficiency of subtitle merging processing is improved.
In an exemplary embodiment, after the step of using the subtitle component corresponding to the selected preset icon as the first subtitle component in response to the selection operation acting on the preset icon in the subtitle editing interface, the method further includes: and caching the text information in the first caption component, so as to acquire the text information in the first caption component from the cache when responding to the release operation, inserting the text information in the first caption component into the target insertion position in the second caption component, and displaying to obtain a new caption component.
In a specific implementation, after the first subtitle component is determined, text information in the first subtitle component may be cached, where the text information may include information such as subtitle text content, subtitle text font size, and subtitle text style, and further, when a release operation is responded, the text information in the first subtitle component may be acquired from the cache, and the text information in the first subtitle component may be inserted into a target insertion position in the second subtitle component and displayed to obtain a new subtitle component.
According to the technical scheme, the text information in the first caption component is cached, so that the text information in the first caption component is obtained from the cache when the release operation is responded, the text information in the first caption component is inserted into the target insertion position in the second caption component, and the new caption component is obtained by displaying the text information in the caption component to be merged based on the cache, and the efficiency of caption merging processing is improved.
In an exemplary embodiment, after the step of moving the action point corresponding to the selected operation and acquiring the positioning information of the action point in the subtitle editing interface in real time, the method further includes: and caching the positioning information, so that when responding to the releasing operation, the last cached positioning information is obtained from the cache as the latest positioning information, and the second subtitle component and the target insertion position are determined based on the latest positioning information.
In practical application, after the positioning information is obtained in real time, the obtained positioning information can be cached, and then when a release operation is responded, the last cached positioning information can be obtained from the cache to serve as the latest positioning information, so that the second subtitle component and the target insertion position can be determined based on the latest positioning information.
Specifically, when the mouse is moved, the subtitle component to be merged (i.e., the second subtitle component) and the subtitle merging position (i.e., the target insertion position) corresponding to the current cursor position of the mouse can be dynamically determined through an application program interface provided by the subtitle editing application platform, and can be placed into the cache, and when the mouse is released, merging between the subtitle components can be realized according to the positioning information of the last cache through the application program interface.
In an example, according to the latest positioning information, a character number corresponding to a position where a cursor is located when the cursor is cached for the last time may be obtained, and may be determined as a specified position where a text is to be subsequently merged and inserted.
According to the technical scheme of the embodiment, the positioning information is cached, so that the last cached positioning information is obtained from the cache as the latest positioning information when the release operation is responded, the second subtitle component and the target insertion position are determined based on the latest positioning information, the other subtitle component to be merged and the specified position of the inserted text can be determined based on the cache, and the efficiency of subtitle merging processing is improved.
In an exemplary embodiment, each subtitle component may have a corresponding time interval, and after the step of presenting the new subtitle component obtained thereby, further includes: displaying a new time interval at the corresponding position of the new caption component; and the new time interval is determined according to the time interval corresponding to the first caption component and the time interval corresponding to the second caption component.
The time interval corresponding to each subtitle component is consistent with the time interval corresponding to the subtitle component in the video to be edited, for example, the time interval corresponding to the subtitle component may be the time interval for displaying the subtitle component in the video to be edited.
In a specific implementation, each subtitle component may have a corresponding time interval, and after the first subtitle component is determined, the time interval corresponding to the first subtitle component may be cached, so that in a subtitle merging process, a new time interval may be determined according to the time interval corresponding to the first subtitle component and the time interval corresponding to the second subtitle component, and the new time interval may be displayed at a corresponding position of the new subtitle component.
According to the technical scheme of the embodiment, a new time interval is displayed at the corresponding position of the new caption component, and the new time interval is determined according to the time interval corresponding to the first caption component and the time interval corresponding to the second caption component, so that the proper caption time span after combination can be ensured.
In an exemplary embodiment, the first caption component may be adjacent to the second caption component, and before the step of presenting the new time interval at the corresponding position of the new caption component, the method further includes: determining the earliest time point and the latest time point from the time interval corresponding to the first caption component and the time interval corresponding to the second caption component; and taking the earliest time point as a starting time point and the latest time point as an ending time point to obtain a new time interval.
In practical applications, the subtitle components to be merged may be two adjacent subtitle components from the same video, that is, the first subtitle component may be adjacent to the second subtitle component, and the time span of the new subtitle component (i.e., the new time interval) may be calculated as follows:
the earliest starting time (namely the earliest time point) of the two subtitles to be merged is used as the starting time (namely the starting time) of the new subtitle component, and the latest ending time (namely the latest time point) of the two subtitles to be merged is used as the ending time (namely the ending time point) of the new subtitle component, so that the time span of the new subtitle component can contain the time span of the two subtitles to be merged.
