In this embodiment of the present application, a local device may be used by an applet to split a video frame of a short video into a preset frame number picture, and a specific form of this embodiment is not limited in this embodiment. The short video refers to a short video, and is an internet content transmission mode, and generally, the short video is a video which is transmitted on new internet media within 5 minutes. The method can be played on various new media platforms, can be pushed at high frequency, is different from micro-movies and live broadcasts, does not have specific expression forms and team configuration requirements like micro-movies in short video production, and has the characteristics of simple production flow, low production threshold, strong participation and the like.
For example, a key frame refers to a frame connecting two different pieces of content, and the video content after the frame has a new change or transition, and the frame has a small black dot mark on the time axis. The ordinary frame is used for measuring the playing time or the transition time, the content of the ordinary frame cannot be set manually, the ordinary frame is automatically filled by the front key frame and the rear key frame and the transition type in the playing process, the ordinary frame is manually inserted or deleted, and the transition time between the front key frame and the rear key frame can be changed.
In one possible example, step S501 includes the following steps A1-A2, wherein,
a1: video frames of the short video are collected.
For example, video is composed of still pictures, called frames, and when the frame rate is lower than 15 frames/second, the continuous motion video will have the feeling of pause, and the PAL system of the tv standard is adopted in China, which specifies 25 frames/second (interlaced mode) of video and 625 scan lines per frame. Since the larger the number of frames, the larger the data amount, the slower the frame rate is to reduce the data amount, and as an example, when the frame rate of the video is reduced from 30 frames per second to 15 frames per second, the data amount is reduced to a certain degree, but the visual effect is deteriorated.
A2: and setting a picture format of the preset frame number picture, and splitting the video frame of the short video into the preset frame number picture.
For example, the common picture formats include a JPG picture format, a PNG picture format, and a BMP picture format. The JPG picture format is a most common image file format, is organized and established by a software development association, is a lossy compression format, and can compress an image in a very small storage space, and repeated or unimportant data in the image can be lost, so that image data is easily damaged. Especially, the use of too high a compression ratio will significantly reduce the quality of the image restored after final decompression, and if a high quality image is sought, it is not suitable to use too high a compression ratio. However, the JPEG compression technique is very advanced, and it removes redundant image data by a lossy compression method, and can display a very rich and vivid image while obtaining a very high compression rate, in other words, can obtain a good image quality with a minimum of disk space. Moreover, JPEG is a very flexible format, has the function of adjusting the image quality, allows files to be compressed with different compression ratios, supports multiple compression levels, the compression ratio is usually between 10: 1 and 40: 1, and the higher the compression ratio, the lower the quality; conversely, the smaller the compression ratio, the better the quality. For example, a BMP file with Mb can be compressed to several tens of KB, but it is also possible to find a balance point between image quality and file size by a trade-off. The JPEG format mainly compresses high-frequency information, well retains color information, is suitable for being applied to the Internet, can reduce the transmission time of images, can support 24-bit true colors, and is also generally applied to images needing continuous tone.
The PNG picture format is used to store a gray image with a depth of up to 16 bits, a color image with a depth of up to 48 bits, and also to store up to 16 bits of alpha channel data. The PNG picture file is generally applied to JAVA programs, web pages or S60 programs because it has a high compression ratio, generates a small file size, and can support color images of 256 colors. It also has the following characteristics:
streaming read/write performance: the image file format allows continuous reading and writing of image data, a feature well suited for generating and displaying images during communication.
Successive approximation display: this feature allows to display the image on the terminal while transmitting the image file over the communication link, displaying the details of the image step by step after the whole outline has been displayed, i.e. displaying the image with a low resolution and then increasing its resolution step by step.
Transparency: this feature may cause certain portions of the image to be hidden from view, creating some distinctive images.
Auxiliary information: this feature may be used to store some text annotation information in the image file.
The BMP picture format is an image file format unrelated to hardware devices, and is widely used. The method adopts a bit mapping storage format, and does not adopt any other compression except that the image depth is selectable, so that the space occupied by the BMP file is large. The image depth of the BMP file can be selected from l bits, 4 bits, 8 bits, and 24 bits. When the BMP file stores data, the scanning mode of the image is from left to right, from bottom to top. Because the BMP file format is a standard for exchanging data related to a graph in the Windows environment, the graph image software running in the Windows environment supports the BMP image format, and a typical BMP image file is composed of four parts:
1: the bitmap file header data structure comprises information such as the type and display content of the BMP image file;
2: the bitmap information data structure comprises the width, height and compression methods of the BMP image, information such as defined colors and the like;
3: palettes, this part being optional, some bitmaps requiring palettes and some bitmaps, such as true color images (24-bit BMP), not requiring palettes;
4: the bitmap data, the contents of which vary according to the number of bits used in the BMP bitmap, uses RGB directly in the 24 bitmap, and uses the color index values in the palette of less than 24 bits.
S502: uploading the important picture set to a cloud space based on a picture mode.
S503: and setting a video recovery model by using the cloud space, and recovering the short video of the important picture set by using the video recovery model.
For example, the video recovery model comprises the function of a video engine, and can transfer the calculation work of video transcoding, storage and distribution to a cloud server, the cloud server completely serves a network cluster transparent to users, and the cloud server bears the specific application calculation tasks of the users, so that the equipment to software of terminals faced by the users are greatly simplified, the final form is a user software terminal with zero maintenance, user hardware equipment is greatly simplified, complex and variable software and hardware are put in a cloud end, and the video application speed of the users is greatly, quickly and conveniently increased.
In one possible example, step S503 includes the following step B1:
and the video recovery model is trained by using the training picture set and optimized according to a training result.
In one possible example, step B1 comprises the following steps B1-B2, wherein,
b1: and inputting the exercise picture set into the video recovery model for recovery training.
B2: and adjusting parameters of the video recovery model according to the training result.
In one possible example, step S503 includes the steps of:
setting a video format of the short video;
for ease of understanding, the video format is exemplified here, and Moving Picture Expert Group (MPEG) is a generic term of video formats such as MPEG-1, MPEG-2, etc., and the MPEG format is an international standard for a Moving Picture compression algorithm that employs a lossy compression method to reduce redundant information in a Moving Picture. The MPEG compression method reserves the most identical parts of two adjacent pictures, and removes the redundant parts of the subsequent picture and the previous picture, thereby achieving the purpose of compression. The Audio Video Interleaved format (AVI) was introduced by microsoft corporation in 1992 and is known and well known along with microsoft windows operating system version 3.1. The audio and video interleaving can interleave the video and the audio together for synchronous playing, the video format has the advantages of good image quality and capability of being used across a plurality of platforms, but the video format has the defects of overlarge volume and non-uniform compression standard, so that the AVI format video edited by early coding cannot be played by a high-version window operating system media player, and the AVI format video edited by the latest coding cannot be played by a low-version window operating system media player. The dynamic bit rate multimedia video package format (RMVB) is a new video format extended from the RM video format upgrading, and has the advantages of breaking through the average compression sampling mode of the original RM format, reasonably utilizing bit rate resources on the basis of ensuring the average compression ratio, and adopting a lower coding rate for picture scenes with few static and motion scenes, so that more bandwidth space can be reserved, and the bandwidth can be utilized when fast moving picture scenes appear. Thus, on the premise of ensuring the quality of a still picture, the picture quality of a moving picture is greatly improved, and thus the delicate balance between the picture quality and the file size is achieved. In addition, the video format also has the unique advantages of built-in subtitles, no need of plug-in support and the like. In the embodiment of the present application, the type of the video format is not limited.
Based on the video format, recovering the short video of the important picture set by using the video recovery model.
S504: and the recovered short video is projected to a large screen end.
In one possible example, step S504 includes the following steps C1-C2, wherein,
c1: and establishing a release link with the large screen end by using an H5 webpage or a small program.
For example, the H5 web page refers to a 5 th generation web page (HTML) and also refers to all digital products made in the H5 language. HTML is the english abbreviation of "hypertext markup language". Most of the web pages viewed by people on the internet are written by HTML. "hypertext" means that a page may contain pictures, links, and even non-textual elements such as music and programs. The "mark" means that the hypertext must be marked by the beginning and end marks containing the attribute, and the browser can display the web page content by decoding the HTML.
C2: and the recovered short video is launched to a large screen end through the launching link.
In one possible example, step C1 comprises the following steps C11-C12, wherein,
c11: and when the release link is established with the large screen end by using the H5 webpage, uploading the recovered short video to the cloud end to generate a video link.
C12: and sending the video link to the cloud desktop.
