Description
Technical field
The present invention relates to the media editing technical field, relate in particular to a kind of high definition media non-linear editing method and device thereof that is applied to digital home.
Background technology
Computer technology has been used very extensive at present in fields such as advertising creative, cartoon making subtitle superposition, brought vitality to advertisement and TV industry; But until just making later on computer substitute traditional video FX production equipment fully, the digital video technology maturation becomes possibility.The aspects such as digital video technology has related to video acquisition and recorded, digital video editor, subtitle superposition, three-dimensional animation production and editor, digital video disk storehouse are deep into these fields with quickish speed.The product of integrated digital video technology will will replace analog video equipment with the advantage of outstanding function and the ratio of performance to price of brilliance.
Conventional video is all processed with analog form, as equipment such as video camera, video tape recorder, editing machine, effect machines, and digital video technology refers to adopt digital form to complete the processing such as recording, preserving of video and editor, material is from being recorded to out works, in the process of processing, almost there is no theoretically the appearance of distortion phenomenon, the copy how many times is all the same with former material.And the nonlinear video editing system is namely to adopt Computer Multimedia Technology, completes the video output of digitlization, stunt editor and the broadcast level of video, as long as the work that coordinates traditional camera-shooting and recording device to need expensive professional equipment just can complete before can completing.Optical disk video camera, hard disk camera have appearred in present video camera, this video camera no longer adopts the tape carrier that keeps a record, but adopt CD even hard disk directly record as record carrier (media), can record very easily lower material, directly input downloads to the enterprising line number code processing of computer.
The nonlinear video editor technology is one of key technology wherein, and it is completed the collection of audio frequency and video and compresses and deposit hard disk in, and can the digital signal that the hard disc of computer inediting is good be output as traditional analog signal.Vision signal in computer can be completed the special technology making of non-linear editing and numerous kinds by software, also can edit together with animation simultaneously, and word, figure easily can superpose on video.Computer is the basis of non-linear editing system, is also the hardware platform of non-linear editing system.The difference of it and common computer be to increase be specifically designed to look, audio signal gathers, image card and the audio card processed, and be used for the material hard disk of signal storage and be used for editor's software.Mainly complete the tasks such as data storage management, audio frequency and video processing, control running software, thereby its performance and the stable running status that has determined entire system.
In the manufacturing process of TV programme, often to carry out outdoor scene to the program scene and record, again the material unification is uploaded in material database by the gatering and editing personnel after recording, then edited by special personnel.along with improving constantly of the effect requirements of being gathered and edited in the scene, usually can use according to actual needs various peripheral material data fetch equipments to carry out the storage of material, peripheral material data fetch equipment is Blu-ray disc for example, the P2 card, the E2 card, and the material for high-quality screen, usually can take very large memory space deposits, but only accept the material file of consolidation form for material database, therefore need to carry out format code transferring to existing material file when uploading, need to obtain just can uploading with the unified material file form of material database, and because program material is numerous, if the situation bigger than normal of program material often occurs, material database can not satisfy the demand that material is deposited, thereby have influence on the normal operation of material database, for existing program making pattern, because needs will all be uploaded the rear editing that just can carry out program wait editing material, therefore for news category, after current events class program needs collection in worksite, in the situation of implementing to broadcast, to make and play program in a short time with regard to being difficult to, simultaneously due to the needs in existing program making process, only intercepted the small part content that gathers in material in actual programs manufacturing process, and remaining material is not used, thereby caused material resource, the waste of material database storage resources.
The program scene record with manufacturing process in, the medium material directly need to be uploaded at the proprietary website of uploading, then by the unified editor of other editor's websites, the material data volume is very large, upload required time long, take the material database storage resources very large, storage causes very large burden to material database.Simultaneously, upload holding time very long, cause the hysteresis quality of editor/broadcast, the work that material database is uploaded in the ageing unification of carrying out data that understanding affect material, can not be based on the data make program of uploading, not only extend the cycle of program making, also be difficult to guarantee the real-time of material-making, need can not guarantee in addition audio-video document to be processed preferentially to complete by its importance.
