Description
Technical Field
The invention relates to the technical field of picture and video editing, in particular to a picture and video editing processing method capable of realizing real-time preview.
Background
At present, a lot of mobile phone editors for plane works exist in the market, and the plane static materials are edited and arranged to manufacture the works, because the processing capability is weak, the processing time is long, the operation difficulty is high, the works need to be uploaded to a cloud computing result and then returned to an editor for previewing, the mode cannot be obtained in what you see, and the computing requirement on cloud computing is higher.
According to the scheme, the primary video is split as much as possible, so that materials can be fully multiplexed, and the waiting time of editors is greatly reduced.
Disclosure of Invention
Therefore, the invention provides a picture capable of previewing in real time and a video editing and processing method, which integrates the editing and previewing of videos and pictures into one step to finish and really achieve what you see is what you get; and the materials are split as much as possible, so that an editor can realize a highly customized video effect, the time cost is greatly saved, and the editor can start without professional training.
The technical scheme of the invention is realized as follows: a picture and video editing processing method capable of previewing in real time comprises the following steps:
s1, material processing, namely downloading a material file to the local, intercepting images of the material frame by frame, performing RGBA analysis on the intercepted images, eliminating invalid parts in the images, compressing the volume of the images, and adjusting the resolution according to requirements;
s2, clipping: identifying the processed material obtained in the step S1, numbering according to time sequence, playing according to the sequence number, and performing operation processing of selecting, rotating, rejecting, covering, shifting, editing and typesetting on the image with the corresponding number according to requirements;
and S3, uploading the clipped works obtained in the S2 to the cloud and storing the clipped works.
Furthermore, the material file comprises parameters related to playing, such as frame rate, resolution, initial position, default picture, first frame identifier and file format; through the parameters, the content can be smoothly played.
Further, the invalid portion of the image in the step S1 is a black shaded portion.
Further, the work needs to be kept in the cloud computing server after the editing in the step S3 is completed, and the saving process is to digitize the material visible to the editor on the screen and convert the content into content recognizable by the computing for storage. The data existing in the computer is composed of two parts, wherein the first part is resource data (original data), and the second part is a parameter, so that the parameter and the original data are isolated, and the disorder of the data among different editors is avoided. The user finishes the whole editing process after finishing storing the data, and the newly opened work can be edited at any time and any place in the future.
The working principle of the scheme is as follows:
s1, material processing, namely downloading a material file to the local, intercepting images of the material frame by frame, performing RGBA analysis on the intercepted images, eliminating invalid parts in the images, compressing the volume of the images, and adjusting the resolution according to requirements; the method comprises the steps of obtaining a video material or a picture material, downloading the material to the local, firstly, an editor needs to download the material to the local, and a material file comprises parameters related to playing and comprises a frame rate, a resolution ratio, an initial position, a default picture, a first frame identifier and a file format. Through the parameters, the content can be smoothly played.
The frame rate is the rate of controlling the playing, and is generally controlled to be not less than 25 frames, so that the user can watch the video without pause. The resolution is compatible with display equipment with different sizes, the condition of overlarge display or insufficient display is avoided, and the same effect of editing and displaying on different equipment types can be achieved through resolution parameters. The initial position refers to the position of the default material in the upper left corner of the screen, the position information stores the position of the current material in the screen, and the position corresponds to each editing, so that the positions of the same material in different edits are independent and do not influence each other. The default picture shows the picture displayed in the downloading process of the material, the editing effect can be completely displayed before the user downloads the material by displaying the default picture, and the effect can be checked under the condition that the network condition of the user is poor or the flow of the mobile network is limited. The first frame mark indicates that a material is generally over 100 frames, and the first frame indicates a frame played for the first time. The file format is as follows: for different materials, the formats of the materials are slightly different, and the common formats are mp4, mov, flv, png, jpg and the like.
S2, clipping: identifying the processed material obtained in the step S1, numbering according to time sequence, playing according to the sequence number, and performing operation processing of selecting, rotating, rejecting, covering, shifting, editing and typesetting on the image with the corresponding number according to requirements;
wherein, the following steps are selected: during the process of playing the material, an editor can select the material, the selected material is paused to be played, and the picture stops at the frame of the material selected by the user. By stopping the playing of the selected material, the editor can be more attentive to editing.
Moving: the material can be moved by pressing the finger on the selected material and moving the finger, and the material can be moved to any position on the screen and also can be moved out of the screen (considering that the finger cannot be moved out of the screen, the material can be displayed partially in the screen all the time).
Rotating: the material can be rotated by pressing a finger on a 'turn' button at the upper right corner of the selected material, and the calculation formula of the rotation angle is as follows
angle is atan2 (finger y coordinate-material center y coordinate, finger x coordinate-material center x coordinate) × 180.0/PI;
if the angle is less than 0 degrees, then also needs angle 180+ (180-abs (angle));
and (3) deleting: the material is deleted from the screen.
S3, uploading the clipped works obtained in the S2 to the cloud and storing the clipped works; after the work is edited, the work needs to be kept in a cloud computing server, the storage process is to convert the material visible to an editor on a screen into data, and the content is converted into content capable of being identified by computing for storage. The data existing in the computer is composed of two parts, wherein the first part is resource data (original data), and the second part is a parameter, so that the parameter and the original data are isolated, and the disorder of the data among different editors is avoided. The user finishes the whole editing process after finishing storing the data, and the newly opened work can be edited at any time and any place in the future.
The scheme has the following beneficial effects:
the scheme integrates the editing and the previewing of the video into one step to finish, and what you see is what you get is really achieved; and the video materials or the picture materials are split as much as possible, so that the editor can realize a highly customized video effect, the time cost is greatly saved, and the editor can start working without professional training.
