Along with the rapid development of the internet, the short video industry is different from military projects, the short video has the characteristics of strong social property and interactivity and fragmented consumption and rapid propagation, and each short video platform attracts a large number of users and traffic; short video platforms such as tremble, microblog, WeChat, fast hand, second time beat and the like exist at home, and short video platforms such as Facebook, Instagram, Snapchat and the like exist at abroad. Many individual users, media agencies, companies and organizations have their accounts operating on various short and large video platforms.
It is often desirable to transmit short videos of the same content simultaneously on different platforms, and each short video platform has different requirements for the optimal viewing aspect ratio of the short videos, typically three video frame ratios of 16:9, 9:16 and 1: 1. At present, one short video content, subtitle and the like are required to be repeatedly made for three times according to the picture ratio of 16:9, 9:16 and 1:1, the making time is long, the time for the short video to be distributed to each platform is greatly delayed, the time for the short video to be distributed is reduced, and the problems are specifically as follows:
1. multiple video clips of the same content in different formats are inefficient
At present, 3 timelines of short videos 9:16, 16:9 and 1:1 are typically required to be established for editing, and the editing efficiency is low because one timeline needs to be correspondingly modified three times;
2. the method for making short video captions of different formats has low efficiency
In the prior art, subtitles are independently manufactured according to the ratio of 9:16, the ratio of 16:9 and the ratio of 1:1, characters, pictures and the like need to be manufactured for many times, and the manufacturing efficiency is low;
3. inefficient short video synthesis of different formats
Currently, synthesis of 9:16, 16:9 and 1: 3 time lines of 1, 3 times of decoding, special effect synthesis and the like, so that the synthesis efficiency is low;
therefore, the production and synthesis efficiency is urgently needed to be improved when the same video content and different video formats are distributed on different platforms.
Disclosure of Invention
The invention aims to: in order to solve the problem that the best viewing aspect ratio of short videos of different platforms at present has different requirements, so that the same section of video content is issued on different platforms and needs to be correspondingly edited, manufactured and synthesized respectively, and the manufacturing efficiency is low, the invention provides a method for manufacturing the short videos with different aspect ratios simultaneously, after the short videos are manufactured on a short video time line with a reference aspect ratio, subtitle templates bound with other aspect ratios are used for modifying subtitle content, different aspect ratios are switched on the same short video program time line, a corresponding video cutting frame is used for cutting pictures, the automatic switching is carried out to the corresponding subtitle template for carrying out automatic adaptation of the subtitle content, the manufacturing of the short videos with different aspect ratios is rapidly completed, finally, video data without subtitles are synthesized once and are superposed to the video data with different aspect ratios according to the data of the cutting frame and the subtitle template, the short video synthesis clusters with different breadth ratios can be rapidly completed, the production and synthesis efficiency of sending short videos with different breadths of different platforms can be greatly improved, and the short video synthesis cluster has the advantages of high efficiency, practicability, convenience in maintenance and cost reduction.

s2: dragging a pre-manufactured caption template group to a short video program time line to manufacture caption contents, wherein the caption template group comprises caption templates which correspond to different aspect ratios one by one, and metadata association is performed among the caption templates;
s3: based on the short video program time line, switching the reference breadth ratio to other breadth ratios, switching the caption template to a caption template corresponding to the breadth ratio, performing self-adaptive typesetting on the caption content on the picture, pre-cutting the picture content of the whole short video program time line, and marking key frames;
s4: forming each frame of pure video picture according to the video data clipped in the S1, and clipping each frame of pure video picture according to the key frames under the condition of different breadth ratios in the S3 to obtain a corresponding clipped picture;
s5: superimposing the caption content formed by the caption templates with the corresponding breadth ratio on each frame of the pure video picture and the cut picture to obtain a corresponding frame of complete picture;
s6: and splicing the complete picture of each frame under the condition of different breadth ratios to obtain short videos with different breadth ratios.
Further, in S2, metadata association is performed between the subtitle templates, specifically, association is performed through GUIDs of the subtitle templates.
Further, in S2, the subtitle template set is dragged to the short video program timeline to produce subtitle content, specifically, the subtitle content is produced through the subtitle template corresponding to the reference aspect ratio based on the reference aspect ratio, and meanwhile, because GUID association is performed between the subtitle templates, the subtitle content corresponding to other aspect ratios is also produced correspondingly.
Further, after the aspect ratio is switched in S3, the subtitle content on the screen is automatically scaled according to the size of the chinese character frame of the subtitle template corresponding to the current aspect ratio and the line feed is performed, so as to complete the adaptive typesetting.
Further, in S3, the picture content of the whole short video program timeline is pre-cropped by using picture cropping frames corresponding to different aspect ratios, where the key frames are used to record position information and time axis information of the pre-cropped pictures of the picture cropping frames.
Further, the pure video picture of each frame obtained in S4 is based on the reference aspect ratio.
The invention has the following beneficial effects:
1. in the invention, a time line is established based on a reference breadth ratio, after the production of clipping, special effects and the like is completed, different breadth ratios are switched on the same short video program time line, a picture cutting frame corresponding to the breadth ratio appears in a picture, the dynamic pre-cutting of the picture is carried out, the cutting data of each frame, namely the position information and the time axis information recorded by a key frame, are recorded and stored on the short video program time line, and the production of the short video clipping and the special effects with different breadth ratios can be rapidly completed.
2. The metadata association between the caption templates of the caption template set is realized, when the caption templates are dragged to the time line of the short video program, the caption templates are automatically switched according to the current breadth ratio, the caption content is subjected to self-adaptive typesetting, the caption manufacture with different breadth ratios is completed, and the method is efficient and practical.
3. The invention carries out asynchronous and simultaneous synthesis on each frame of picture, cuts the picture according to key frames with different breadth ratios based on pure video pictures, superposes corresponding subtitle contents to complete synthesis, and the pure video only needs to be decoded once and synthesized once, thereby greatly improving the synthesis efficiency of short videos with different breadth ratios.
