Description
Technical field
The present invention relates to audio-video intelligent editing technique fields, and in particular to a kind of multi-channel sound video automated intelligent editor
Method.
Background technique
Traditional audio-video records software support screen and the external video record of multichannel, saves after the completion of recording and records view
Frequency Outcome Document has a large amount of redundancy, invalid segment to need to delete in Outcome Document, can only manual edit, delete and could obtain
It to final achievement, while needing to screen the segment of needs in each road video, then does synchronization process, heavy workload is complicated
It is cumbersome, and the achievement synchronism and continuity developed are poor.In daily teaching process, the teaching task of teacher is heavy,
There is no the Video Courseware of free time editor recorded with hall, therefore a kind of software function of the highly desirable automatic editing and processing of energy is given
Give support.
Summary of the invention
In view of the deficiencies of the prior art, the invention discloses a kind of multi-channel sound video automated intelligent edit methods, pass through
Multi-channel sound audio video synchronization during the present invention can lecture daily teaching, speech, training is recorded, and is patrolled by a set of software
It collects treatment mechanism realization to edit each channel of recording process automatically, is finally issued as an achievement video.
Specific technical solution is as follows:
A kind of multi-channel sound video automated intelligent edit methods, specific steps include
S1: user starts micro- lecturer and records software；
S2: acquisition channel is recorded in selection；
S3: starting is recorded, and software automatically records human-machine interactive information and records acquisition file；
S4: recording terminates, and software carries out automated intelligent editor according to record file is recorded；
S5: it closes micro- lecturer and records software；
Specifically, according to S3 step, after starting is recorded, the various behaviour of software AM automatic monitoring and record user in recording process
Make, which includes screen touch command, keyboard operation, mouse action, electronic script control instruction, each camera channel displaying behaviour
Work, audio-frequency information collection analysis and video pictures collection analysis；
Specifically, software carries out automated intelligent editor to the audio-video of recording automatically according to monitoring and record result；
Specific automated intelligent edit methods step includes,
1) recorded file loads, according to software automated intelligent monitor log as a result, original audio-video document is recorded in load；
2) partitioning marks, and records information according to the human-computer interaction that software automated intelligent is monitored, automatic segmentation is chosen at achievement
Needed for audio-video segment, and marked in project file；
3) transition special effective is added, software adds transition special effective according to the media file fragments of cutting automatically；
4) Video Redundancy delete, software according to record achievement audio-frequency information compare, delete automatically cough, plosive, for a long time without
The segments such as sound；Software is compared according to achievement audio/video information is recorded, and is automatically deleted long-time picture still in video, unchanged
Segment, delete invalid record and user forgets the redundancy segment that pass hull closure is recorded；
5) audio-video optimizes, and exports achievement files-audio and carries out noise reduction process；
6) achievement exports, and carries out coding compression to audio-video, and the audio-video document after merging coding is mp4 achievement；
7) engineering saves, and automated intelligent editing and processing result is saved engineering by software, so that the secondary editor of user uses.
The utility model has the advantages that
1, of the invention by the audiovisual features analysis to screen and each picture pick-up device channel, and during combination user's instruction
Behavior event carries out intellectual analysis, final to realize software automated intelligent editor and issue achievement.It eliminates audio-video and records completion
Complicated editing afterwards, user are not necessarily to the professional ability for having audio-video editing；Meanwhile Automatic Editing Function is also exempted from for user
The quality time for being largely used to editing is gone.
2, need to complete a large amount of micro- class, video open class, the synchronous record class in classroom during the daily teaching of school teacher
It is put into editing work Deng needing to expend a large amount of time and efforts of teacher after the completion of, these courseware recordings, in addition very much
Teacher does not have the later stage compilation ability of audio-video recorded file, and the present invention can be very good to solve the problems, such as this.
3, the present invention remains each paths recorded information synchro edit, and generates the video of independent completion, automatic to edit
Original document is not influenced with publication, therefore if desired user does a small amount of adjustment to automatic editor's achievement, it can be in editorial project file
Secondary editor, had both been able to achieve automatic editor, is also able to satisfy personalized manual editing's needs, provides secondary editting function.
Detailed description of the invention
