Description
Technical field
The present invention relates to the video editing field, relate in particular to a kind of method that realizes the three-dimension varying special efficacy.
Background technology
Films such as the film that present spectators are watched, TV play all can add special efficacy through post-production.And transition special effective also is the most common a kind of special efficacy.Now spectators watch film to be not limited to the plot of film, more are the vision shocks that special efficacy that film adds is brought.Therefore, more special efficacy is by developing gradually.
The least unit that constitutes telefilm is a camera lens, and the shot sequence that is joined together to form of camera lens is called paragraph one by one.Each paragraph all has certain single, complete relatively meaning, as shows a course of action, shows a kind of correlationship, shows a kind of implication or the like.It is complete narration level in the telefilm, and just as the curtain in the drama, fictitious chapters and sections are the same, and paragraph links together one by one, has just formed complete telefilm.Therefore, paragraph is the most basic version of telefilm, and telefilm layer of structure in terms of content shows through paragraph.And transition between paragraph and paragraph, scene and the scene or conversion are referred to as transition.
The method of transition is a lot, on connected mode, also can be divided into skill transition and two big types of no skill transitions.Skill transition: utilize the stunt skill that two paragraphs are connected together.Be characterized in: both caused linking up of vision easily, caused the separation of paragraph again easily.The skill conversion is usually used in the conversion of big paragraph, than being easier to form tangible paragraph level.Usual way: fade over, dissolve, page turning, draw picture, iris out and ensphere, fix etc.No skill transition: adopt direct switching way, connect two sections contents with the natural transition of camera lens.
The inventor finds that in carrying out R&D process there is following defective in prior art when making transition special effective:
(1) transition special effective effect of the prior art is single, can not well improve the video displaying quality;
(2) making of special efficacy need be bought specific hardware and could realize that still cost an arm and a leg, limitation is low.
Summary of the invention
The embodiment of the invention provides a kind of method that realizes the three-dimension varying special efficacy, greatly improves the make efficiency of program, has expanded the function of hardware, has high degree of freedom.
This method specifically may further comprise the steps:
A kind of method that realizes the three-dimension varying special efficacy, this method comprises:
Obtain at least two video datas, and with said at least two video datas according to the order lay of timeline in orbit;
Analyze the center point coordinate and the image information of the forward video data of timeline in said at least two video datas;
With said center point coordinate is that initial point makes up three dimensional space coordinate system;
Fasten long and wide long and wide quadrilateral of said at least two video datas that is not less than of structure at said three dimensional space coordinate;
The image information of the video data that said timeline is forward maps to said quadrilateral;
Receive user instruction;
According to said user instruction move, rotation and/or the said quadrilateral of convergent-divergent;
When said quadrilateral is moved, behind rotation and/or the convergent-divergent, show the video data after timeline leans on.
According to the embodiment of the present invention, through making up quadrilateral, and video data is mapped to this quadrilateral; Thereby realize motion through the tetragonal motion control video pictures of control; Greatly improve the make efficiency of program, expanded the function of hardware, have high degree of freedom.
