A kind of nonlinear editing system
Technical field
The present invention relates to electronic equipment manufacturing technology field, particularly relate to a kind of nonlinear editing system.
Background technology
Continuous progress along with computer technology and integrated circuit technique, linear editing system (system that is used for video tape and film) is extraordinary obsolescence, is replaced based on computer hardware platforms, the nonlinear editing system of looking Audio Processing card and large scale digital memory carrier at present.
Nonlinear editing system is the product that computer and digital to television technology combine, and it is added by computer basically looks the Audio Processing card and be equipped with corresponding non-linear editing software and form.Therefore characteristics such as numeral non-linear editing technology has editting function in the video program production process powerful, convenient to operation are widely used in the manufacturing process of TV programme.Wherein, the non-linear " of the " in the nonlinear editing system is meant be not workflow with the linear mode, and promptly it has broken through in the past that the operator must successively be the operator scheme of order with Pgmtime under the linear work environment.Under the nonlinear operation mode, the operator can freely select target, needn't be order with the time order and function.Simply say, need not be as edit tape when being exactly montage picture is searched in F.F. or rewinding to and fro.
Under the conventional linear edit mode, need the combination of multiple devices such as videocorder, cut bank, animation stand, sound console, film titler usually, finish program later stage montage, Series Code, stunt making, subtitle superposition, look work such as audio mix.And under non-linear editing mode, only need 1 nonlinear editing system can finish that multiple devices, multidigit technical staff cooperate the work that just can finish under above-mentioned traditional edit mode based on digital technology.In conventional linear program making process,, can only rely on to duplicate sometimes and achieve the goal because linear editing can't be made amendment quickly and easily.Because index word is big, so influenced picture quality to a great extent, has also prolonged the time of program making.And non-linear editing system biggest advantage just is its non-linear editing, it can carry out montage to program quickly and easily, and nonlinear editing system is under the computer disk recording mode, each section material all is that the form with a computer documents is stored on the computer disk, by software for editing, can freely make up the editing that these files are finished whole program.In the middle of completed program, revise if desired, extend or the shortening fragment, only need to revise the file sequence of being correlated with and get final product.
Nonlinear editing system is made up of hardware system and software systems two large divisions, and hardware system comprises computer, looks Audio Processing card, mass storage, interface system; Software section comprises systems soft ware and application software.For traditional analog video signal, when in computer, carrying out non-linear editing, must be at first video source, the vision signal that promptly comes from equipment such as analog video camera, video tape recorder, video disc player converts digital store that computer can handle on hard disk, and this process is called digitized process (comprised sampling and quantized two steps).Therefore nonlinear editing system comes down to the computer system of an expansion.
Present nonlinear editing system, generally all be with general work station or personal computer as system platform, in the editing process and the video/audio of edited result all be stored in the hard disk.Editor's process is exactly that digitized video/audio signal is handled on high-speed and high-efficiency ground.And look the " engine " that the Audio Processing card is the non-linear editing system, and in nonlinear editing system, play a part very importantly, it is directly determining the performance of whole system.What the numeral nonlinear editing system will be stored is a large amount of video/audio materials, and data volume is very big, therefore needs jumbo stored digital carrier, and hard disc (being hard disk) is a kind of selection in the present circumstance.Nonlinear editing system is when work, and looking audio material is to be uploaded on the hard disk of computer from video tape recorder, notes through exporting video tape recorder again to behind the editor.The transmission of signal realizes by the video/audio signal interface.In addition, in order to be fit to the needs that network transmits, the interface of nonlinear editing system also will be considered the trend of radio and television digital technology and evolution of computer networks.In nonlinear editing system, digital interface is made up of two parts: the interface of computer-internal memory bank and system bus, and the interface of nonlinear editing system and external equipment.
From the hardware configuration of nonlinear editing system, it has just finished the work such as I/O, compression/de-compression, storage of video/audio, and this not enough.Finish non-linear editing work, also corresponding application software must be arranged, could form the perfect nonlinear editing system of a cover.Software systems mainly comprise operating system software and non-linear editing application software, non-linear editing software is meant and operates on computer hardware platforms and the operating system, the application software system that is used for non-linear editing that on the platform that develops software, develops, this is the core of non-linear editing system, and most of operating process of nonlinear editing system all will be finished in non-linear editing software.This class software is broadly divided into tailored version and universal.Wherein the software of tailored version mostly by the nonlinear editing system developer according to the characteristics of selected Audio and Video Processing Card and special exploitation, as the software of Xin Aote Silicon Valley video companies exploitation.
Because there is above-mentioned huge advantage in nonlinear editing system, so very fast having obtained in the program making of TV station used widely.Application by nonlinear editing system, the final program that the editorial staff of TV station obtains is exactly the project file of a nonlinear editing system, in this project file, write down the material of all references in the program: look audio material, captions material and stunt etc., and the organizational form of these materials.See that as us head, captions, stunt and the run-out of each issue program all have a unified form in each program in the TV station in the TV of being everlasting, therefore early stage, program often had very big reference value to the program of back.When carrying out the making of current program, the editing saving personnel are not in order to need to repeat to make above-mentioned contents such as head, captions, stunt and run-out with Unified Form, usually need the project file that program is generated to early stage to reuse, transfer foregoing.
In the prior art nonlinear editing system to early stage the program project file the repeated use mode as follows, at first pass through the engineering of the newly-built current program of nonlinear editing system, transferring then needs the early stage of reference program project file to merge in the newly-built engineering, the content of Unified Form such as the head that use in the reference engineering that will need at last, captions, stunt, run-out copies in the new engineering by variety of way, thereby realizes the recycling to foregoing.
Yet the inventor finds that there is following technological deficiency in nonlinear editing system of the prior art when realization is of the present invention:
1, from the nonlinear editing system angle, when early stage, the program project file merged to newly-built engineering, can cause the increase of nonlinear editing system memory cost, not only prolonged edit session, and can influence the stability of nonlinear editing system, cause system in case of system halt, cause losing of operational data.
2, from using editorial staff's angle of nonlinear editing system, merge engineering and increased editorial staff's operation complexity, because in a new construction, be merged into an engineering that has existed, can in new construction, produce a large amount of operands, therefore the editorial staff in these a large amount of operands, selects the operand of own needs will become one very difficult, and thing consuming time.
If when 3 editorial staffs wish to use stunt in the preliminary engineering of merging, then must be undertaken,, so further aggravate the big problem of system resource overhead because the shared resource of stunt itself is very big by the mode of duplicating stickup.
If 4 each issue program all need before program engineering is merged in the engineering of current period program, can produce some extra materials in the process of so this merging engineering, increase along with these extra materials that accumulate over a long period, all bring very big problem will inevitably for program making Network Management and space, thereby influence whole making stability of network and fail safe.

Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail:
As shown in Figure 1, be embodiment of the invention nonlinear editing system structure chart, the inventive point of this nonlinear editing system is to simplify programming process by engineering template.Comprise that at the nonlinear editing system of the above-mentioned technical characterictic embodiment of the invention engineering template transfers module 11, material memory module 12 and material and replace module 13, engineering template is transferred the engineering template that module 11 is used to transfer the program correspondence; Material memory module 12 is used to preserve the audio material of looking of described program needs; Material is replaced module 13 and is used for the material preserved according to material memory module 12 and engineering template is transferred engineering template that module 11 transfers carries out element and replace, and generates final program project file.
Wherein, preferably, this nonlinear editing system also comprises engineering template creation module 14, is used to program to generate corresponding engineering template, and this project template comprises the common content of program.As be the engineering template of a correspondence of each program (as: programs such as Focus, news chain broadcast) generation of TV station, comprise the employed constant content of program in this project template, program title captions for example, the form of footmark picture, libretto literal and font size etc., the contents such as stunt that also comprise the required use of program are as the stunt of program head and run-out.Particularly, look audio material in the program regular change may take place, yet unless the style of this program etc. change, otherwise the stunt of this program is constant often for needed stunt in the program.Yet increasing stunt in program making is work complicated, the most consuming time for the editing saving personnel, therefore the engineering template by the embodiment of the invention can be solidificated in comparatively fixing contents such as stunt in the engineering template, and the replacement that makes the program editorial staff only need carry out material gets final product.The editorial staff only need be placed on main energy the collection of material and select when making each issue program and get final product like this, and need not be concerned about the problems such as stunt loading of load, significantly reduced editorial staff's workload, they can be freed from the editing of loaded down with trivial details complexity, thereby energy is concentrated on program on the creation, improve program quality.And also can be the editorial staff by the embodiment of the invention special editor and optimizational function to engineering template is provided, can make a part of editorial staff specialize in the creation of engineering template, refinement the professional division of labor, further promote the quality of content such as captions, stunt in the program.
The embodiment of the invention has proposed a kind of embodiment of engineering template content; yet need to prove that the engineering template content that the embodiment of the invention proposes is one of more excellent execution mode; and the embodiment of the invention focuses on introducing the notion of engineering template in the program making of nonlinear editing system; programming process is simplified in application by engineering template, therefore any variation of this content all be should be embodiment of the invention protection range and contains.
Engineering template can be considered as the engineering that the editorial staff creates out by nonlinear editing system, this project template mainly comprises following content:
That 1, was quoted in this program looks audio material.
2, above-mentioned membership credentials of looking between the audio material, for example above-mentioned in time the precedence relationship etc. of looking between the audio material.
3, above-mentionedly look employed stunt on the audio material.
4, employed all captions materials (comprise main title, surtitle, roll screen word in the engineering
Curtain and quiet frame captions etc.).
5, employed stunt on the above-mentioned captions material.
In the content of above-mentioned engineering template, for program fixing in the TV station, asynchronous program has only 1 and 2 s' variation bigger, the membership credentials of promptly looking audio material and looking audio material change greatly, and all be constant basically for 3,4,5 content, yet for a program making process, the most complicated, the most consuming time is exactly the making of 3,4,5 contents.
Wherein, preferably, this nonlinear editing system also comprises simple editing module 15, is used for replacing 13 pairs of engineering templates of module at material and carries out the engineering template that carries out after element is replaced being edited after element replaces it.
Pass through the embodiment of the invention, in nonlinear editing system is programmed process to the introducing of engineering template notion, can all make the corresponding engineering template for each program of TV station, in this engineering template, understand employed constant content in the program, as main title, the footmark picture, the form of libretto literal and the size of font, and added stunt content is included in this project template.In each issue program of making, the editorial staff transfers the engineering template of this program correspondence, and all materials of being prepared for this phase program, replaces device by material then material replacement old in the engineering template is promptly obtained final program.As the program that ground is rational for, can introduce Pekinese's geography possible today, therefore can select Pekinese's picture for use at the program head, yet the stunt that loads on this picture but need not change, and therefore only need original picture in the engineering template be replaced by the nonlinear editing system of the embodiment of the invention to get final product.From above-mentioned to the application of embodiment of the invention engineering template as can be seen, nonlinear editing system by the embodiment of the invention is programmed, need not new construction of the prior art, will before the program engineering operation such as merge, the editorial staff only need replace and look the editor that audio material can be finished program accordingly now, is the very big improvement to existing programming process.
As shown in Figure 2, be editing saving software flow pattern in the embodiment of the invention nonlinear editing system, described editing saving software can be simplified programming process, improves program production efficiency, may further comprise the steps:
Step S201 is that program generates engineering template by described editing saving software, and engineering template comprises the common content of program.It for example is the engineering template of a correspondence of each program generation of TV station, comprise the employed constant content of program in this project template, program title captions for example, the form of footmark picture, libretto literal and font size etc., the contents such as stunt that also comprise the required use of program are as the stunt of program head and run-out.In one embodiment of the invention, engineering template specifically comprises: look audio material, look the membership credentials of audio material and look stunt on the audio material.Preferably, this project template also comprises: the stunt of using on captions material and the captions material.
Step S202 transfers the engineering template of program correspondence by described editing saving software.
Step S203 prepares the needed material database of looking audio material and being kept at described editing saving software of this phase program, and by described editing saving software described engineering template is carried out element and replace.In each issue program of making, the editorial staff transfers the engineering template of this program correspondence, and all materials of being prepared for this phase program, replaces device by material then material old in the engineering template is replaced.Preferably, because the membership credentials of only looking audio material the fixing program and looking audio material in TV station change greatly, so the embodiment of the invention can be replaced the membership credentials of looking audio material and looking audio material in the engineering template.
Step S204 edits the engineering template that carries out after element is replaced by described editing saving software.If replace the needs that the result who replaces the back is discontented with full border program at material, can edit it, further improve the practicality of embodiment of the invention engineering template.
Step S205 generates final program project file.
Step S206 if to the modification or the optimization of engineering template, then preserves the program project file that generates as the engineering template of program, replace original engineering template.This function can make special editorial staff at any time engineering template be made amendment and optimize, to improve program quality.
