Exemplary method
First embodiment
As shown in fig. 1, an embodiment of the present invention provides a video segment clipping processing method based on a mobile terminal, where the video segment clipping processing method based on a mobile terminal can be used in mobile devices such as mobile phones and tablet computers. The method in the embodiment of the invention comprises the following steps:
s100, acquiring a video file needing to be edited;
in the embodiment of the invention, when the video file shot by the user needs to be shared to the uploading platform, the video file needs to be uploaded, and the size of the video file is larger than the uploading limit, the video file needs to be edited. A video file to be clipped is selected and the mobile terminal acquires the video file to be clipped.
In order to realize the fast segmentation of the video clip, the embodiment of the invention needs to set a video fast segmentation operation menu interface on the mobile terminal in advance before the implementation of the invention: for example, setting the video fast segmentation operation menu interface includes: a video preview area, a frame-by-frame preview area, a value selection area, a segment entry by number of segments and by size of each segment, and an available value cue after the segment.
And setting an operation function corresponding to the menu interface: the video preview area is used for previewing a video file needing to be edited; the frame-by-frame preview area can realize the frame-by-frame preview of the video file needing to be clipped; the numerical value selection area is used for selecting a specified segmentation number value or selecting a specified segmentation length value of each segment for a video file to be clipped, and the segmentation according to the number of segments and the segmentation according to the size of each segment are used for respectively entering a clipping menu function according to the number of segments and the size of each segment; and the segmented available numerical prompt words are used for segmented prompting.
Specifically, the method for setting a video fast segmentation mode on the mobile terminal in advance comprises the following steps: segmenting according to the number of segments and segmenting according to the size of each segment; wherein the segmenting by the number of segments is to equally divide the video clip into X segments; for example, if the video file is divided into X segments on average, the total length of the video file is ZMB, and each segment is Z/X MB.
The segmenting according to the size of each segment is to sequentially segment the video according to the specified size Y of each segment, for example, each segment of YMB after segmentation is shared by OMB; expected to be divided into O/Y sections.
The present invention also sets in advance a specific segment number default value, for example, 6 segments, for the number of segments to segment clips, and a specific per-segment size default value, for example, 10MB per segment, for the size of each segment to segment clips, before the specific embodiment.
Step S200, previewing the video file needing to be clipped;
in the embodiment of the invention, when the video file needs to be edited, the video file needing to be edited can be previewed. The user can conveniently check whether the video file needing to be edited is correct.
Step S300, a clipping instruction of the video file to be clipped is obtained, and whether the clipping instruction is a preset segmentation according to the number of segments or a segmentation according to the size of each segment is judged;
in this embodiment, after previewing a video file to be edited before editing, a user may select a corresponding editing command through a preset menu. The mobile terminal of the present invention obtains the clipping instruction for the video file to be clipped, and determines whether the clipping instruction is a preset number of segments or a segment with a size of each segment.
For example, after a user clicks the fast segmentation to enter a video clip, the function selects a clip instruction, a clip instruction for the video file to be clipped is obtained, and whether the clip instruction is a preset clip instruction segmented according to the number of segments is judged; and when the clipping instruction is not the preset clipping instruction segmented according to the number of the segments, judging whether the clipping instruction is the preset clipping instruction segmented according to the size of each segment.
Step S400, when the clipping instruction is a preset segmentation according to the number of segments, controlling to clip the video file needing to be clipped according to the specified number of segments on average;
in the embodiment of the invention, when the clipping instruction is a preset segmentation according to the number of segments, the video file needing to be clipped is controlled to be segmented and clipped according to the specified number of segments on average.
Specifically, for example, the mobile terminal receives a clipping instruction for rapidly segmenting the video file needing to be clipped; when the clipping instruction is a preset clipping instruction segmented according to the number of the segments, acquiring a numerical value X needing to be segmented; controlling to evenly divide the video file clip to be clipped into X sections, wherein the total length of the video file is ZMB, and each section is Z/X MB; that is, in the embodiment of the present invention, if the total length of the video file to be clipped is 110MB and the number of required segments set by the user is 10 segments, the video file with the total length of 110MB is averagely divided into 10 segments, each segment being 11 MB.
In the embodiment of the invention, the segmentation effect can be synchronously displayed in the frame-by-frame preview area for the sub-video files which are segmented and clipped, and the length of each segment of time can be checked by controlling dragging.
In the embodiment of the present invention, the number of segments: the video clipping is performed on the condition of the number of video files obtained after average segmentation clipping. The average division is X sections: the number of the video files obtained after the clipping is finished is determined according to the average number of the video files obtained after the segmentation clipping (X is a value selected by a user in real time).
In the invention, the video file clip is averagely divided into X segments, the total length of the video file is ZMB, each segment is Z/X MB, X is a real-time numerical value, and MB is megabyte. The method refers to the condition of the number of video files obtained after average segmentation clipping, and the sum of the expected byte size of a single file of the video files obtained after clipping and the byte size of all the files is the original file size.
Step S500, when the clipping instruction is a preset segmentation according to the size of each segment, controlling to clip the video file needing to be clipped according to the specified segmentation size of each segment;
in the embodiment of the invention, when the clipping instruction is preset to be segmented according to the size of each segment, the video file needing clipping is controlled to be clipped according to the specified size of each segment.
In the invention, the size of each section: means that video clipping is performed on the condition of the byte size of a single video obtained after segmented clipping.
Specifically, for example, when the mobile terminal receives a clipping instruction for rapidly segmenting the video file to be clipped; when the clipping instruction is a preset clipping instruction segmented according to the size of each segment, acquiring the size value Y of each segment to be segmented; controlling the video file clips needing to be clipped to be sequentially segmented and clipped according to the specified size of each section of YMB; for example, when the total length of a video file to be clipped is 120MB, and a platform that a user needs to upload a video can only receive 12M video files per segment, in this embodiment, the user can set a clip by segment according to the size of each segment, and then the video file with the total size of 120MB is rapidly clipped according to the size of each segment of 12M, so that the clip 120M/12M is 10 sub-video files.
In the embodiment of the invention, the segmentation effect can be synchronously displayed in the frame-by-frame preview area for the sub-video files which are segmented and clipped, and the length of each segment of time can be checked by controlling dragging.
And step S600, storing the segmented and clipped video file.
In the invention, the video file after the fast segmentation and clipping can be saved by receiving the user operation instruction.
