It will be understood by those skilled in the art that the foregoing electronic devices and servers are merely exemplary and that other electronic devices or servers, now known or later developed, that may be suitable for use in the present disclosure are intended to be included within the scope of the present disclosure and are hereby incorporated by reference.
Based on this, embodiments of the present disclosure provide a method for automatically loading subtitles.
The execution main body of the display method provided by the embodiment of the present disclosure may be the electronic device or the server, or may also be a functional module and/or a functional entity capable of implementing the video content display method in the electronic device or the server, and the specific implementation may be determined according to actual use requirements, which is not limited in the embodiment of the present disclosure. The following takes an execution subject as an electronic device as an example, and exemplarily describes a display method provided by the embodiment of the present disclosure.
Fig. 2 is a flowchart illustrating a method for automatically loading subtitles, which is used in an electronic device as shown in fig. 2, according to an exemplary embodiment and includes the following steps S11-S12.
In step S11, the first character information is acquired in response to a first predetermined operation for copying the first character information.
The first predetermined operation described above may be any single operation or a group of operations formed by a series of operations for copying the first textual information. In the case where the electronic apparatus is a personal computer, the first predetermined operation may be a keyboard and mouse operation, for example, a keyboard and mouse operation such as "Ctrl + C". When the electronic device is a mobile phone or a PAD, the first predetermined operation may be a click operation or a long press operation.
In step S12, the first subtitle information generated based on the first text information is displayed in the first subtitle region of the video editing interface, that is, the first subtitle information is generated based on the first text information and displayed in the first subtitle region of the video editing region.
In the above embodiment, first, in response to a first predetermined operation for copying the first text information, the first text information is acquired; and then, displaying the first subtitle information on the video editing interface according to the first character information. According to the scheme, the first subtitle information can be generated in the first subtitle region of the video editing interface according to the copied characters, the problem that the subtitles are edited by manually typing or manually pasting the characters is relieved and even thoroughly solved, and the efficiency of editing the subtitles is high.
In an actual application process, there may be a plurality of predetermined operations for copying the text information, and only part of the text information in the plurality of copied text information may be used for subtitles of the video, in order to make the displayed subtitles more accurate in this case, in an embodiment of the present application, as shown in fig. 3, the step S11 is implemented by the step S110 and the step S111.
In step S110, in response to the first predetermined operation, a prompt message is displayed on the video editing interface, where the prompt message is used to prompt whether to determine the first subtitle information according to the first text information. In an actual application process, the prompt information may be a prompt popup, and the prompt popup may display "whether the system detects that the text copy is performed and the text is automatically added as a subtitle". Of course, the prompt pop-up window with the above text is not limited to be displayed, but may also be some other specified prompt information in the video editor, for example, the prompt information is a prompt with "copy? "is a rectangular icon. Those skilled in the art can set the appropriate prompt information according to the actual situation, and can be a prompt icon or the like.
In step S111, the first character information is acquired in response to a second predetermined operation applied to the presentation information. The second predetermined operation may be at least one of a click operation, a long-press operation, a double-click operation, and a slide operation, and may be determined according to actual conditions. In the case of receiving a second predetermined operation on the prompt message, it may be determined that the first subtitle information is determined according to the first text information, and thus the first text information is acquired based on the second predetermined operation.
As shown in fig. 4, the step S12 can be implemented by a step S120 and a step S121, wherein in the step S120, the first subtitle information is determined according to the first text information; in step S121, the first caption information is displayed in the first caption area.
In an actual application process, in some cases, for example, in a case where a time length of the first text information displayed in a predetermined manner substantially coincides with a time length of the video being edited, or in a case where although the time length of the first text information displayed in the predetermined manner is shorter than the time length of the video being edited, the video only partially requires subtitles, the first text information is first subtitle information, and then, correspondingly, the step S120 includes: and determining the first text information as the first subtitle information.
In some cases, the first text information may not satisfy the requirement corresponding to the first caption information, and the first text information may be a part of the first caption information, and in order to further accurately, efficiently and completely display the first caption information, in an embodiment of the present application, the step S120 includes: determining whether the preset time length of the first character information displayed according to a preset mode is shorter than the time length of the video being edited; comparing the first text information with a predetermined caption segment in a caption database under the condition that the predetermined duration is less than the duration of the video, wherein the caption database comprises a plurality of the predetermined caption segments; and in the case that the similarity between the first text information and the target part is greater than a first preset threshold value, determining at least one part of a target subtitle segment including the target part as the first subtitle information according to the length of the video being edited, wherein the target part is one part of the target subtitle segment with the same preset time length as the first text information, and the target subtitle segment is one of a plurality of preset subtitle segments including the target part. According to the scheme, the first subtitle information corresponding to the video being edited can be automatically supplemented according to the first character information.
For example, the first text message is "once a true love was placed before me, i did not get a treasure", the caption database is a database of classical lines segments in a movie, wherein one predetermined caption segment is "once a true love was placed before me, i did not get a treasure, i got back to remoter when me lost, the most painful one in human world, if we can give me a chance to come again in the last day, i would say three words to that girl, i love you, if we do not add a term to that love, i hope to be ten thousand years", the predetermined caption segment is a target caption segment, wherein the target portion is "once a true love was placed before me, i did not get a treasure", if the first predetermined threshold is 90%, the similarity of the target portion and the first text message is 100% greater than the first predetermined threshold, therefore, the predetermined caption segment can be determined as "once a true love is put in front of me, i has no treasure, i repels me when me loses, i has the most painful thing in the world, if me can give me a chance to come again the day, i can say three words to the girl, i love you, if not to add a term to the love, i hopes to be a ten thousand years" target caption segment, then the corresponding first caption information is determined according to the duration of the edited video, firstly whether the duration of the edited video is the same as the duration of the target caption segment displayed according to a predetermined mode is determined, and if the duration of the edited video is the same as the duration of the target caption segment displayed according to a predetermined mode, the target caption segment is determined to be the first caption information. If the duration of the edited video is longer than the duration of the target caption segment displayed in the predetermined manner, the target caption segment is used as the first caption information, and the display manner of the corresponding first caption information is adjusted according to the duration of the edited video, for example, generally speaking, the display duration corresponding to one sentence is 2s, so that the display duration of the first caption information is the same as the duration of the video, the display duration of one sentence can be increased. If the duration of the edited video is less than the duration of the target caption segment displayed in a predetermined manner, a portion of the target caption segment, which includes the target portion and has the same duration as the duration of the edited video, is used as the first caption information, and specifically, the portion of the target caption segment can be intercepted by combining the voice information and the target portion of the video to be used as the first caption information.
In a specific application, the caption database is actually a material library, wherein the predetermined caption segment may be a speech of a classical segment in a movie, a classical segment popular on a network, or any other suitable text segment such as a verse library, and a person skilled in the art may select a suitable caption database according to actual conditions.
Of course, in an actual application process, the method may further include a step of constructing a subtitle database, and the construction process may refer to a construction process of another language database, which is not described herein again.
In order to more accurately display the first subtitle information in the first subtitle region, in a specific embodiment of the present application, the displaying the first subtitle information in the first subtitle region includes: determining position information of a first subtitle subregion, wherein the position information comprises a length and a starting position, the length of the first subtitle subregion is a display length of the first subtitle subregion, the length of the first subtitle subregion represents a video time length corresponding to a first subtitle segment in the first subtitle subregion, the starting position of the first subtitle subregion represents a first video frame image corresponding to the first subtitle segment, and which video frame images corresponding to the first subtitle segment are determined according to the position information, wherein the first subtitle segment is obtained by dividing according to the first subtitle information; according to the position information, a plurality of first subtitle sub-regions are displayed in the first subtitle region, that is, according to the length and the starting position of the first subtitle sub-regions, corresponding first subtitle sub-regions are displayed, and the first subtitle segments are located in the first subtitle sub-regions in a one-to-one correspondence manner, as shown in fig. 5.
In a specific embodiment, the video editing interface further includes an image area, the image area displays a plurality of video frame images, the plurality of video frame images are sequentially arranged along a predetermined direction, the plurality of first subtitle sub-areas are sequentially arranged along the predetermined direction, one of the first subtitle sub-areas is located at one side of the corresponding plurality of video frame images, the plurality of video frame images and the corresponding first subtitle sub-area are correspondingly displayed, and the predetermined direction is a length direction of the first subtitle sub-area. In particular, the start position of the first subtitle subregion may be aligned with the start position of the first video frame image of the corresponding plurality of video frame images, i.e. the projection of the start position of the first subtitle subregion onto the video frame image region is located on the start edge of the first video frame image. The length of the first subtitle subregion may be the same as the display length of the corresponding plurality of video frame images. The projection of the starting position of the first subtitle subregion in the video frame image region may also be located in the first video frame image of the corresponding plurality of video frame images, and the length of the first subtitle subregion may also be smaller than the total display length of the corresponding plurality of video frame images. As shown in fig. 5, five video frame images on one side of the first subtitle subregion 101 are the five video frame images corresponding to the first subtitle segment in the first subtitle subregion.
Of course, in practical applications, the first subtitle sub-area is not limited to being located on one side of the video frame image as shown in fig. 5 (see fig. 5 in a view facing the screen, and the upper side, the left side, and the right side below are all viewed in this view), and may also be located on the upper side of the video frame image.
It should be noted that the first subtitle sub-region may also be displayed at other display positions, for example, the first subtitle sub-region is located at the left side or the right side of the corresponding video frame images. In the prior art, it is generally referred to that the image frame display area is a main track, the subtitle display area is a sub-track, and the sub-track and the main track are distributed in a direction perpendicular to the predetermined direction, specifically, as shown in fig. 5, the first subtitle area 100 in fig. 5 can be regarded as the sub-track, and the frame image area 200 is the main track.
