In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the application.

Fig. 1 is a flowchart of video recording according to an embodiment of the present application, where the method may be performed by a video recording apparatus, and the apparatus may be implemented in software and/or hardware, and the apparatus may be configured in an electronic device, for example, a terminal or a server. The electronic equipment is a terminal and comprises a smart phone, a palm computer, a tablet personal computer, a wearable device with a display screen, a desktop computer, a notebook computer, an integrated machine, an intelligent household device and the like.

As shown in fig. 1, the method specifically may include:

s110, acquiring a condition set, wherein the condition set comprises a plurality of corresponding relations; the correspondence includes a mode switching condition and a video recording mode.

A condition set is a set of elements in correspondence.

The correspondence is used to describe a video recording mode that should be used when a certain mode switching condition is satisfied.

The mode switch condition is used to measure whether a node switching the video recording mode is reached. The present application does not limit what the mode switching condition specifically includes. Illustratively, when a user wishes to record a video that teaches a certain knowledge point, and the user wishes to teach the knowledge point via a file (e.g., a presentation or document, etc.), each page in the file may be considered a section of content, and the page number of the section of content may be considered a mode switching condition. For another example, when the user wishes to record a video that teaches a knowledge point that the user is planning to explain from several aspects, each aspect being a content section, keywords of the content section may be used as a mode switching condition.

A video recording mode is a specific video recording mode that defines how a video display interface should be displayed. Optionally, the video recording mode includes at least one of: the video display interface comprises the number of the functional areas, the positions of the functional areas on the video display interface, the sizes of the functional areas, the corresponding relation between the functional areas and the information sources and configuration parameters corresponding to the information sources.

The functional area may be, for example, an area in a video display interface for displaying a video or an image transmitted by a certain signal source. Illustratively, 3 different video display interfaces are provided in fig. 2-4. In fig. 2 and 3, the video display interface includes 2 functional areas. In fig. 2, 2 functional areas are shown in picture-in-picture form. In fig. 3, 2 functional areas are shown in the form of a split screen display. In fig. 4, the 3 functional areas are also shown in the form of a split screen display. However, the number, arrangement, and size of the functional areas are different from those of fig. 3 and 4.

In practice, the correspondence between the functional area and the information source is specified in the video recording mode. In an exemplary scenario where a teacher explains a certain knowledge point, three signal sources are set, wherein the first signal source transmits a teacher figure recording result, and the teacher figure recording result reflects the expression and limb actions of the teacher; the second signal source transmits a whiteboard recording result, and the whiteboard recording result reflects the blackboard writing of the teacher; the third signal source transmits and outputs a designated background image, an image or video related to the knowledge points to be explained, and the like. The layout of the functional area on the video display interface in a video recording mode may be preset as shown in fig. 2, where the functional area 1 corresponds to a third signal source and is used for displaying a background image. The functional area 2 corresponds to the first signal source and is used for displaying the recorded image result of the teacher. In another video recording mode, the layout of the functional area on the video display interface is shown in fig. 4, where the functional area 1 corresponds to a second signal source and is used for displaying the whiteboard recording result. The functional area 2 corresponds to a third signal source for displaying a background image. The functional area 3 corresponds to the first signal source and is used for displaying the recorded image result of the teacher.

The configuration parameters corresponding to the information sources may be parameters related to video or images transmitted by the signal sources, for example. By way of example, configuration parameters corresponding to the various information sources may include video resolution, frame rate, volume, beauty setting parameters, and the like.

S120, in the video recording process, the current recording information is periodically acquired.

The current recording information may be, for example, information acquired in real time during video recording. This application is not limited to the details of its inclusion. In practice, the current recording information may be determined according to the mode switching condition of the correspondence in the condition set.

Illustratively, the mode switching condition includes a page number of the file, and the current recording information includes a page number of the file in the video currently transmitted from the signal source, that is, a page number of the current interpretation. In this scenario, the specific implementation method of this step may include: in the video recording process, periodically acquiring an explanation image of a file to be explained; and determining the current explanation page number of the file to be explained based on the explanation image of the file to be explained. The determining the current explanation page number of the document to be explained based on the explanation image of the document to be explained may specifically include identifying the explanation image of the document to be explained to obtain the current explanation page number of the document to be explained.

As another example, the mode switching condition includes a keyword of a content section; the current recording information includes keywords of the current lecture content. In this scenario, the specific implementation method of this step may include: in the video recording process, periodically acquiring an explanation image and explanation audio information of a file to be explained; determining keywords of the current explanation content based on the explanation images and/or the explanation audio information of the files to be explained; the determining, based on the explanation image of the to-be-explained document, the keyword of the current explanation content may specifically include: and identifying the explanation image of the to-be-explained file to obtain the keywords of the current explanation content. Based on the explanation audio information, determining keywords of the current explanation content can specifically include: converting the explanation audio information into text information; based on the text information, keywords of the current lecture content are determined.

S130, if the current recording information meets the mode switching condition in the first corresponding relation, switching the currently used video recording mode into a target video recording mode, wherein the first corresponding relation is any corresponding relation in the condition set; the target video recording mode is a video recording mode in the first corresponding relation.

Illustratively, the condition set includes N correspondences. If at a certain moment, the current recording information is judged to meet the mode switching condition in the corresponding relation with the number i, and the corresponding relation with the number i is the first corresponding relation. And switching the video recording mode currently used into a video recording mode in the corresponding relation with the number i. Wherein i and N are positive integers. I is more than 0 and less than or equal to N.

If the mode switching condition includes the page number of the file, the current recording information includes the page number of the file in the video currently transmitted from the signal source, that is, the page number of the current explanation. At a certain moment, the current explanation page number is consistent with the page number in the first corresponding relation, and the currently used video recording mode is switched to the target video recording mode.

If the mode switching condition comprises keywords of the content section; the current recording information includes keywords of the current lecture content. At a certain moment, the similarity between the keywords of the current explanation content and the keywords in the first corresponding relation is larger than a set similarity threshold, and the currently used video recording mode is switched to the target video recording mode.

According to the technical scheme, the condition set is obtained through setting, and the condition set comprises a plurality of corresponding relations; the corresponding relation comprises a mode switching condition and a video recording mode; in the video recording process, current recording information is periodically obtained; if the current recording information meets the mode switching condition in the first corresponding relation, switching the currently used video recording mode into a target video recording mode, wherein the first corresponding relation is any corresponding relation in the condition set; the target video recording mode is a video recording mode in the first corresponding relation. The essence of the method is that in the video recording process, whether the node of video recording mode switching is reached is automatically identified according to the preset corresponding relation, and when the node of video recording mode switching is identified, the video recording mode switching is automatically performed. Therefore, after video recording, a user does not need to splice and process the video by means of clipping software, the difficulty and cost of post-processing can be reduced, and the video recording efficiency is improved.

On the basis of the above technical solution, optionally, before S110, referring to fig. 5, the method further includes:

s210, responding to a corresponding relation configuration instruction, and displaying a corresponding relation configuration page; the corresponding relation configuration page comprises a plurality of candidate configuration conditions and a plurality of candidate recording modes.

The correspondence configuration instruction may be, for example, information that conveys to the electronic device (i.e., the execution subject of the video recording method provided in the present application) that the user wishes to configure the correspondence. In practice, after detecting that the user performs a certain trigger operation (for example, clicking a control with a function of configuring the correspondence, or completing a sliding operation of a preset track, etc.), a correspondence configuration instruction is generated.

The candidate configuration conditions may be, for example, alternative options provided for the user that may be mode switching conditions. Illustratively, the first and second modules are connected to one another. In this application, candidate configuration conditions are parsed by the electronic device itself, rather than entered by the user.

Illustratively, prior to S210, candidate configuration conditions are acquired. Optionally, the specific implementation method for obtaining the candidate configuration condition may include: acquiring a file to be explained; dividing a file to be explained into a plurality of content sections; candidate configuration conditions corresponding to each content section are determined based on the feature information of each content section, respectively.

The file to be explained is a file which needs to be used in the process of recording the video by a user.

The content section is a division result obtained after the document to be explained is divided. The method for dividing the files to be explained is not limited. Illustratively, the to-be-explained file is divided according to page numbers, and one page of the to-be-explained file is one content section. Or dividing according to the theme of the content included in the file to be explained, wherein one theme is a content section. Or dividing according to the chapters of the content included in the file to be explained, wherein one chapter is a content section. The characteristic information of a content section may be information that distinguishes one content section from other content sections. Illustratively, the characteristic information of the content section includes page numbers, keywords, titles, and the like of the content section.

The user uploads the file to be explained, and the electronic device automatically divides the file to be explained according to page numbers, and takes the page number of each page as a candidate configuration condition. If the file to be explained is a presentation file with 20 pages in total, 20 candidate configuration conditions are obtained by analyzing the presentation file, wherein the 20 candidate configuration conditions are respectively page 1, page 2, page … … and page 20.

The candidate recording mode may be, for example, preset, and may be an option provided to the user as a video recording mode. Illustratively, the candidate recording mode includes at least one of: the video display interface comprises the number of the functional areas, the positions of the functional areas on the video display interface, the sizes of the functional areas, the corresponding relation between the functional areas and the information sources and configuration parameters corresponding to the information sources.

In practice, optionally, before S210, the method further includes: acquiring application information of a video to be recorded and a video recording mode set; the set of video recording modes includes a plurality of different video recording modes. And determining candidate recording modes from the video recording mode set based on the purpose information of the video to be recorded.

The usage information of the video to be recorded may be, for example, recording purpose information describing the video to be recorded. The content specifically included for recording purposes is not limited in this application. By way of example, video recording purposes may be recording life, recording events (e.g., recording meetings, recording lectures, recording news), education and learning (e.g., recording educational videos), promoting and marketing, etc.

The application information of the video to be recorded is input by a user or optional application information is provided for the user, and after the user selects the provided optional application information, the application information selected by the user is used as the application information of the recorded video.

Optionally, an association relationship between the video recording mode and the application may be preset, and according to the association relationship between the video recording mode and the application information of the video to be recorded, a candidate recording mode is determined from the video recording mode set, and then the identification information of the candidate recording mode is displayed in the corresponding relationship configuration page.

The identification information of the candidate recording modes may be, for example, information that distinguishes one candidate recording mode from other candidate recording mode items. Illustratively, the identification information of the candidate recording mode may include a name, a number, a thumbnail of the video display interface, etc. of the candidate recording mode.

The video recording mode set includes 50 different video recording modes, wherein, among the 50 different video recording modes, only the video recording mode numbered 4-6 is associated with the purpose of recording teaching video, and after the purpose information of the video to be recorded is obtained, the identification information of the video recording mode numbered 4-6 is displayed in a corresponding relation configuration page for user selection.

In practice, there may be a large number of candidate recording modes included in the set of possible video recording modes. And for different purposes, the number of candidate recording modes in common use is relatively small. By setting the application information based on the video to be recorded, the candidate recording mode is determined from the video recording mode set, and the candidate recording mode can be screened before the corresponding relation between the mode switching condition configured by the user and the video recording mode, so that the range of the candidate recording mode required to be selected by the user is reduced, and the purpose of improving the efficiency of the subsequent configuration corresponding relation is achieved.

Further, before the video recording mode set is acquired, the method further includes: displaying a video recording mode configuration page, wherein the video recording mode configuration page comprises a plurality of functional areas; responding to a configuration instruction of the target functional area, and configuring the target functional area to obtain a video recording mode; configuring the target function area includes at least one of: deleting a target functional area, adjusting the position of the target functional area, adjusting the size of the target functional area, adjusting the corresponding relation between the functional area and an information source, and adding special effects to an image transmitted by the information source corresponding to the functional area; the target functional area is any one of a plurality of functional areas; video recording modes are added to the video recording mode set. The essence of the arrangement is that the configuration permission of the video recording mode is opened to the user, so that the user can configure the video recording mode according to the self-requirement, and the personalized video recording mode configuration requirement of the user can be met.

S220, in response to the selection operation of the candidate configuration conditions and the selection operation of the candidate recording modes, a corresponding relationship is established between the selected candidate configuration conditions and the selected candidate recording modes.

S230, adding the corresponding relation into the condition set.

For example, referring to fig. 6, before video recording begins, the electronic device first displays a video usage collection page for acquiring usage information of a video to be recorded. In fig. 6, four options of "record teaching video", "record news", "record conference", "and" other "are provided in the video usage collection page. The user may need to select one of the options. The electronic equipment obtains the purpose information of the video to be recorded based on the options selected by the user. Next, referring to fig. 7, the electronic device shows a correspondence configuration page. And uploading the file to be explained in the corresponding relation configuration page by the user. In fig. 7, the name of the uploaded file to be explained is "XXXX". The electronic equipment analyzes the file XXXX to be explained to obtain candidate configuration conditions, and displays the candidate configuration conditions in a mode switching condition display area. The electronic equipment determines candidate recording modes from the video recording mode set according to the application information of the video to be recorded; assuming that the number of the determined candidate recording modes is 3, the identification information of the 3 candidate recording modes is displayed in the candidate recording mode display area. Referring to fig. 7, if the user selects the candidate configuration condition 2 and the candidate recording mode 3, a correspondence is established between the candidate configuration condition 2 and the candidate recording mode 3, and the correspondence is added to the condition set.

According to the technical scheme, the corresponding relation configuration page is displayed by setting the corresponding relation configuration instruction; the corresponding relation configuration page comprises a plurality of candidate configuration conditions and a plurality of candidate recording modes; in response to the selection operation of the candidate configuration condition and the selection operation of the candidate recording mode, establishing a correspondence between the selected candidate configuration condition and the selected candidate recording mode; the corresponding relation is added into the condition set, and the essence is that the user is allowed to configure the corresponding relation between the mode switching condition and the video recording mode according to the own needs before the video recording is formally started. Thus, the personalized video recording requirement of the user can be met.

It will be appreciated that prior to using the technical solutions disclosed in the embodiments of the present disclosure, the user should be informed and authorized of the type, usage range, usage scenario, etc. of the personal information related to the present disclosure in an appropriate manner according to the relevant legal regulations.
