Description
Technical field
The present invention relates to a kind of studio video and audio-editing technical field, particularly relate to that a kind of hyperchannel video and audio is online performs in a radio or TV programme editing system.
Background technology
The mode that studio multi-channel video is now shot with video-corder mainly contains following two kinds:
(1) based on the studio recordings mode of legacy hardware devices.Major equipment has the formations such as instructor in broadcasting's switching device (switching device of multiplex video signal source), storage system (storing the equipment of video and audio video-tape or data file), Character Generator (studio floor exports the equipment of captions).
(2) based on the multichannel video and audio studio recordings mode of computer platform.This mode is the whole ITization of studio recordings system based on legacy hardware devices in the first, and the switching being realized studio multipath signal source by software systems is recorded.
The shortcoming of these two kinds of studio recordings systems:
1 once occur that instructor in broadcasting's handoff error can not recover at the scene, and the later stage can only carry out cutting synthesis by amended record video and audio or the finished product file recalling whole recording.
2, these two kinds of studio recordings is all simply gather recording, and is all the composite document exported.Realize secondary editor, then all can only export this process by decoding, editor, coding.For example captions mistake, then can only by blocking the mode correction of editor when the later stage is revised.
Summary of the invention
For above-mentioned defect and the problem of prior art, the object of this invention is to provide that a kind of hyperchannel video and audio is online performs in a radio or TV programme editing system, solve existing video and audio and perform in a radio or TV programme editing technique and can not realize the problem that online editing and instructor in broadcasting switch backtracking.
In order to achieve the above object, the invention provides following technical scheme:
A kind of hyperchannel video and audio is online performs in a radio or TV programme editing system, and comprise computer hardware system and software systems, computer hardware system is as the operation platform of software systems; Wherein said software systems comprise:
Video and audio acquisition module (AV acquisition module), complete collection one or more external video/audio signal source any forms data file and is stored in computing machine local hard drive;
Video and audio monitoring module, is connected with video and audio acquisition module, in order to monitor one or more external video/audio signal source any, or monitors the local video and audio material of one or more computing machine;
Video and audio mark handover module, be connected with video and audio acquisition module, video time wire module, audio time wire module and audio frequency and video picture and text composite document output module respectively, in order to mark one or more extraneous signal source any of video and audio acquisition module, and the video and audio after mark is sent to video time wire module, audio time wire module and audio frequency and video picture and text composite document output module respectively;
Caption editing module, with subtitle list model calling, for editing the captions facsimile file of audio frequency and video project file, and is stored in the local hard drive of computing machine by this captions facsimile file;
Subtitle list module, respectively with caption editing module and captions picture and text timeline model calling, the captions facsimile file editted via caption editing module be stored in computing machine local hard drive can be recalled, according to time sequencing list, the captions facsimile file in list is sent to captions picture and text timeline module in order simultaneously;
Captions picture and text timeline module, with subtitle list model calling, receives the captions facsimile file in subtitle list module, forms editable captions picture and text project file;
Video time wire module, marks handover module with video and audio and is connected, and receives the video file after video and audio mark handover module mark, forms editable video project file;
Audio time wire module, marks handover module with video and audio and is connected, and receives the audio file after video and audio mark handover module mark, forms editable audio frequency project file;
Audio frequency and video picture and text composite document output module, handover module and subtitle list model calling is marked respectively with video and audio, video and audio is marked the video file after handover module switch flag and audio file, and the captions facsimile file synthesis finished product video and audio file that subtitle list module exports; And
Audio frequency and video picture and text project file output module, is connected with captions picture and text timeline module, video time wire module and audio time wire module respectively, exports the editable audio frequency and video picture and text project file that formation one is complete.
Further, also comprise special video effect module, be connected with video time wire module, the special effect processing on video time wire module between video segment itself or two sections of video segments.
Hyperchannel video and audio of the present invention is online perform in a radio or TV programme editing system be perform in a radio or TV programme editing technique based on traditional video and audio basis on innovatively multichannel video and audio to be recorded and editor is put and carried out at one time, initiative proposing onlinely performs in a radio or TV programme editing technique.The present invention except can carry out multichannel video and audio recording and editor except, emphasis solves online editing and instructor in broadcasting switches the problem recalling these two aspects, the mark of multipath signal source switches recording and can generate two files simultaneously, one is composite document, one is the editable timeline project file (file do not synthesized, comprise video project file, audio frequency project file, captions picture and text project file), realize online editing; And switch afterwards instructor in broadcasting personnel, switching point can be realized and recall a period of time forward or backward, realize instructor in broadcasting and switch backtracking. by mistake
In sum, direct beneficial effect of the present invention has following:
1, finished product file is formed.Gather the finished product composite document recorded can directly read and apply.
2, project file is formed.Gather the project file (comprising video engineering, audio frequency engineering, picture and text engineering) do not synthesized recorded can cutting easily on the time line, pull, revise, additions and deletions, change order etc.
3, instructor in broadcasting's backtracking.When occurring that switching is broadcast in misleading, the present invention can easily recall signal forward or backward, until find switching point accurately, can catch most suitable camera lens.
4, record limit in limit is compiled.Can while to record, online editing simultaneously, shortens the video and audio-editing time greatly, greatly improves video and audio-editing efficiency.
5, single channel multi-channel recording.Both single channel video and audio can record editor online, and also multichannel video and audio can record editor online, achieve the combination of studio system and video editing system (nonlinear editing system).
