Third embodiment

Referring to fig. 6, a third embodiment of the present application proposes a shooting method, based on the first embodiment, after step S30, further including:

step S40, caching the target video;

and step S50, storing the target video when receiving the recording ending instruction.

After the target video is generated, caching the target video into a memory, in the embodiment, the mobile terminal can generate and cache the target video at regular time during shooting of the shooting video, or can generate and cache the target video during starting shooting to pausing shooting when the shooting pause is detected; optionally, the target video is generated and cached at regular time, in an actual shooting process, if a shooting application crashes, the shot shooting video may be lost, and in order to prevent the shooting application from being lost, the target video is generated and cached at regular time, optionally, the cached target video in this embodiment is an internal processing process of the mobile terminal, in an exemplary technique, when the shooting application crashes, the mobile terminal stores the target video in an album by default, at this time, the process of recording the shooting video by the user may not be finished, for the user, even if the shooting application is restarted, only a new section of the shooting video can be recorded, and the recording cannot be continued on the basis of the previous section of the shooting video, if a newly recorded shooting video and a previously recorded delayed shooting video need to be combined into a section of the video, only the editing can be performed manually, and the editing process is cumbersome, therefore, user experience is poor, the target video is cached at first instead of being directly stored as the video finally output to the album, whether recording is finished or not is detected after the target video is cached, the cached target video is obtained when a recording finishing instruction is received, the cached target video is stored, and the target video can be stored to the album or other applications when being stored.

After the cached target videos are obtained, the mobile terminal can also detect whether the target videos include at least two videos, wherein the at least two videos refer to more than two videos, and when the target videos include at least two videos, the target videos are spliced to obtain spliced videos, and the spliced videos are stored.

When at least two target videos are spliced, the target videos can be spliced according to the cache sequence of the target videos, and the target videos can also be spliced according to the splicing sequence selected by a user.

When splicing is carried out according to the caching sequence of the target videos, the caching time of each target video can be obtained, and each target video is automatically spliced according to the caching time sequence; when splicing is carried out according to the splicing sequence selected by the user, prompt information of the splicing sequence can be output, the prompt information of the splicing sequence is prompt information for prompting the user to adjust the video splicing sequence, the prompt information can be used for displaying each target video in an interface on the basis of a grid or list mode, the splicing sequence of each target video is adjusted in the interface by the user, after the fact that the user is adjusted is detected, each target video is spliced on the basis of the splicing sequence adjusted by the user, spliced videos are obtained, and the spliced videos can be stored and output to an album.

Referring to fig. 7, the output prompt information of the stitching order may be displayed in a grid form, as shown in fig. 7, an implementation of the prompt information when the stitching order is adjusted is shown, in the figure, 3 target videos are included, in the figure, "1", "2" and "3" indicate the front-back order of the stitching, that is, when the stitching is performed, 1, 2 and 3 are sequentially stitched, thumbnails of three target videos are shown below 1, 2 and 3, a user may adjust the stitching order by sliding the thumbnails left and right, adjust each target video in the order of 1, 2 and 3, after the adjustment is completed, the spliced target videos may be stored by clicking the lower square, and if the adjustment order needs to be cancelled, the square may be clicked.

Optionally, this embodiment further provides an implementation manner of recording the photographic video in segments, if a user needs to record each target video respectively and splice each target video, the mobile terminal provides three operations of starting recording, pausing recording and ending recording, optionally, starting recording for triggering shooting the photographic video, pausing recording for triggering caching the target video, ending recording for triggering splicing the cached target video, referring to fig. 4, 8 and 9, based on fig. 4, after "recording" is clicked, recording is started and converted into an interface displaying fig. 8, in the interface of fig. 8, the recording button is changed into a pause recording button, when it is detected that the user clicks the pause recording button, the interface illustrated in fig. 8 is converted into the interface illustrated in fig. 9, and a target video before recording is paused is cached, and a thumbnail of the generated target video is presented in a column of "thumbnail of cached video" at the lower left, optionally, if the user clicks a "cache video thumbnail", the user may enter an interface for adjusting the splicing sequence, the interface for adjusting the splicing sequence may be as shown in fig. 7, when it is detected that the user clicks a "√" button in fig. 7, the splicing sequence may be saved, but the video splicing is not performed temporarily, until the user returns to the interface shown in fig. 9, the user clicks the "√" and then saves the result, if the user still needs to record the next segment of video, the user may click a continue recording button, the display screen of the mobile terminal is switched from the interface shown in fig. 9 to the interface shown in fig. 8, if the user clicks the "√" on the lower right, the mobile terminal automatically splices the currently cached multiple segments of target videos, obtains the spliced videos, saves the spliced videos, outputs the spliced videos to an album, and returns to the interface shown in fig. 4, to begin recording a new target video.

In this embodiment, the target video is cached; when a recording ending instruction is received, storing the target video; therefore, the problem that the target video is lost or terminated accidentally due to the situation of application breakdown and the like can be avoided, and the recording of multiple sections of target videos is further realized.
