Description
Technical field
The application belongs to video editing techniques field, and the side of Freehandhand-drawing video elementary is quickly combined in more particularly to a kind of video
Method.
Background technology
With the rise of short video industry, video becomes a kind of important form of expression.But now industry for regarding
The processing of frequency, such as the Freehandhand-drawing element such as addition paster, expression and dynamic title, are also using traditional Video processing software.This
Kind handles software, and the unit for being all based on picture frame goes processing, although processing is accurate, the software of needs installation specialty,
The use of learning software, on the premise of skilled, it is also desirable to take a lot of time and operate to handle a very short video, because
Change between frame and frame is required for operator oneself to go to handle, and this also make it that the processing of video is difficult general in domestic consumer
And.
Video (Video) is a kind of storage format of dynamic image, and it has several important attributes：Video content, video
Length, resolution ratio, frame per second, compressed format and coded format.
Resolution ratio refers to the width and height of picture frame in video, generally it is believed that resolution ratio is higher regards
Frequently, visually appearing to be more clearly.
Frame per second (FrameRate) is for literal meaning, that is how many two field picture per second in video, its numerical value by
The 6-8 of early stage per second, and 120 till now are per second.For video, as long as the frame per second per second not less than 30 frames,
Visually, it is being exactly continuously.
Compressed format, video is referred to when file storage is carried out, the compression algorithm used.Video common at present
Form has：
MPEG is MotionPictureExpertsGroup abbreviation, is included more including MPEG-1, MPEG-2 and MPEG-4
Kind video format.
AVI (AudioVideoInterleaved, Audio Video Interleaved)) by be Microsoft Corporation release video sound
Frequency stagger scheme (video and audio weave in synchronize broadcasting), it is inexpensive, the low resolution on a kind of desktop system
The video format of rate.
One kind in the audio/video compression specification RealMedia that RM, RealNetworks company are formulated, is positioned at
In terms of video flowing, it may also be said to be the person of firstly appearing of video stream technology.
