Abstract
The invention discloses multi treatment methods for a key frame curve after modifying the exit and entry points of materials, which are used for non-linear editing and clipping software and video and audio post special effect treatment and synthesis software; a plurality of types of treatment to the key frame curve after modifying the exit and entry points of the materials select appropriate material fragments for the exit and entry points of the materials which often need to modify during a program production and editing process, so that the editing requirements are met. The treatment methods for the key frame curve after modifying the exit and entry points of materials are realized by adopting the treatment method of setting the state of a key frame, adding key frames to material fragments and setting the changes of the exit and entry points of the key frames as well as the method of modifying the exit and entry points of the key frames, so that the defect that the completion and the motion trend of the key frame curve are damaged because the lengths of the material fragments are changed is overcome, so that the program production quality can be better ensured and the operation is simple.
Description
Technical field
The present invention is used for non-linear volume editing software and video and audio later stage special effect processing and composite software, and crucial frame curve exists
Multiple processing methods after modification material access point.
Background technology
Using non-linear volume editing software and video and audio later stage special effect processing and composite software, Making Movies, advertisement, piece
It is often necessary to adjust parameters, setting key frame, thus forming one in time in the image/video processing procedure of flower etc.
The effect of change.During most of video editor editor's video file, the edit operation of frame is all passed through, multiple from input file
Make and complete in output file.Frame file only need to replicate one by one, export and can complete edit operation in the process.But
When carrying out the special effect processing such as special efficacy, transition, speed change, if edit routine does not know that the frame of input comprises special efficacy operation, it can
Image can be processed in full of prunes mode.And many letters related to content format can be comprised in usual video file
Breath, but in editing process, the configuration of frame file needs in the video editor option by actual requirement effect, being set to,
Need substantial amounts of editing, thus realizing above Video editing work.
It is often necessary to the access point of modification material chooses suitable material fragment, with full in program making, editing process
The requirement of foot editor.So it is accomplished by the solution of a kind of key frame curve and the linkage of material out points.
Content of the invention
The present invention relates to non-linear volume editing software and video and audio later stage special effect processing and frame curve crucial in composite software
Multiple processing methods after modification material access point, it can fully solve in program making, editing process, often needs
The access point of material to be changed chooses suitable material fragment, to meet the problem of the requirement of editor.When to a certain parameter setting
After the good crucial frame curve adjusting, need the variation tendency of crucial frame curve and editor's material to keep certain correlation, such as repair
Change material enters (going out) point, but does not affect position in Storyboard for the crucial frame curve；Or when entering of modification material fragment
After (going out) point, on this parameter corresponding key frame curve, the position of key frame keeps and enters the relative position that (going out) puts constant；Or
The scope that person changes key frame effect after material fragment enters (going out) point position is still consistent with the length of fragment.
In order to solve problem above, the following Three models of the relationship type of setting out points and key frame：
Pattern one：Holding pattern, refers to that the position of key frame does not change when fragment out points change.
Pattern two：Follow the mode, refers to when fragment out points change, and equal proportion is put down therewith for the position of key frame
Move.
Pattern three：Zoom mode, refers to that the position of key frame zooms in and out when fragment out points change, scaling
Ratio and fractional time length scale ratio are identical.
As shown in Figure 1：A is crucial frame curve, and b is fragment.When b fragment is foreshortened to original 50%, crucial frame curve
Accordingly change.
By such three kinds of different patterns, can avoid destroying crucial frame curve because changing the length of material fragment
Integrality and the movement tendency of curve.Preferably ensure the quality of program making, and simple to operate.
Brief description
For the technical scheme of the clearer explanation embodiment of the present invention, below will be to required use in embodiment description
Accompanying drawing do simple introduction：
Fig. 1：Three models analysis diagram is shown
Fig. 2：Initial setting up state diagram is shown
Fig. 3：Illustrate to change access point position, tupe is set to：Holding pattern
Fig. 4：Illustrate to change access point position, tupe is set to：Follow the mode
Fig. 5：Illustrate to change access point position, tupe is set to：Zoom mode
Fig. 6：Illustrate to change out a position, tupe is set to：Holding pattern
Fig. 7：Illustrate to change out a position, tupe is set to：Follow the mode
Fig. 8：Illustrate to change out a position, tupe is set to：Zoom mode
Specific embodiment
Non-linear volume editing software involved in the present invention and video and audio later stage special effect processing are bent with key frame in composite software
Multiple processing methods after modification material access point for the line, are used directly among Video processing, in order to better illustrate reality
Apply process, be exemplified below：
It is assumed that with the addition of one section of material fragment in Storyboard, (length of fragment can be random length, for ease of description, false
The fixed material length added is 200 frames), starting point in 0 frame position of Storyboard, end point in 200 frame position of Storyboard, to this
Fragment adds the stunt of movement effects, adds one section of crucial frame curve to the translation parameters of the Y direction under motion trick,
If J curve effectJ is as shown in Figure 2：
Next, the access point position of modification material fragment, point Text will be entered it will be modified to the position of the 100th frame, be respectively adopted
Above-mentioned Three models check the situation of change of crucial frame curve after change access point, such as Fig. 3, shown in 4,5.
From figure as can be seen that after changing the access point position of material fragment, if the tupe of key frame is chosen as protecting
Hold pattern, automatically intercept and remain from 100 frames to the crucial frame curve in 200 this region of frame；If tupe is to follow mould
Formula, intercepts and applies material fragment till now from the curve 0 frame to 100 frames on former key frame curve；If tupe
It is chosen as zoom mode, by the length of the length according to new material fragment for the movement locus of former key frame curve and essence material fragment
Carry out the scaling of equal proportion, the variation tendency of complete reservation key frame.
If likewise, modification material fragment go out a position, a position will be gone out and be set to the 100th frame, the result obtaining
As Fig. 6, shown in 7,8：
Comprehensive above example, changes material access point every time and can be summarized as following steps：
Add key frame to material fragment
The processing mode of setting key frame access point change
The access point position of modification key frame
By way of revocation or revocation is just permissible, or by changing the length of material, such as stretch or compression material
The mode of length carries out the termination editor of Video processing.
