Abstract

PURPOSE:To enable automatic speech signal edition and the labor saving of an editing work by performing the dubbing edition of a recording medium on which speech signals are recorded according to the front and rear time codes of the discontinuous points out of time codes recorded on an edition- finished movie film. CONSTITUTION:A magnetic tape on which continuous time codes before edition are recorded is dubbing-edited by an editing device 4. At this time, dubbing the speech signals of a part sandwiched by the front and rear time codes of the discontinuous points is eliminated by the control of the time codes recorded on the recorder. At the next stage, the magnetic tape is reproduced by the editing device 4 and reproduced speech signals are supplied to a sound track recorder 5. Hereby, the speech signals are recorded on the sound track of the movie film. In this case, time codes obtained from a moving picture projector 1 are read by a time code reader 2 and the editing device 4 is simultaneously controlled by these time codes. Thus, only the cutting-edition of the movie film is performed and the speech signals are automatically edited according to the time codes.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of editing a motion picture audio signal for recording the sound signal on the soundtrack of an edited motion picture film.

[Conventional technology]

Figure 5 shows, for example, Niss MBC E-Journal (S
M P T E J urnal, March, 1
984) is a block diagram showing a conventional method for editing a movie audio signal, and in FIG. A film-shaped magnetic tape 8 is a soundtrack adding machine that records the audio signal reproduced from the magnetic tape 7 on the soundtrack of the movie film 6.

In FIG. 6, 6a is a movie film before editing, and 7a is a film-shaped magnetic tape before editing.

The numbers shown as "01-20" are movie films 6a.

It shows the number of frames on the magnetic tape 7a.

FIG. 7 shows the edited movie film 6 and magnetic tape 7, in which frames r07-09 and frames 14-16 have been cut.

Next, the operation will be explained. The movie film 6 and the magnetic tape 7, which have already been assembled, are run synchronously using the perforation holes provided in each, and the audio signals reproduced from the magnetic tape 7 are transferred to the soundtrack adding machine 8.
It is recorded on the soundtrack of movie film 6. Further, the motion picture film 6 and the magnetic tape 7 are produced by cutting the motion picture film 6a and the magnetic tape 7a before editing shown in FIG. 7 in synchronization with each other.

[Problem to be solved by the invention]

The conventional editing method for movie audio signals is carried out as described above, so when cutting and editing the movie film 6a and the magnetic tape 7a, it is necessary to cut the audio according to the video, so it is necessary to cut both mechanically. The work must be done in synchronization, and for this reason the motion picture film 6a
The cutting of the magnetic tape had to be done at the same time as the cutting of the perforation, which required the work to be done twice.Also, since the alignment of the two was done mechanically, editing was carried out with the misalignment of the perforation holes still present. When you put it away,
There were problems such as it becoming impossible to repair.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a method for editing a movie audio signal that can automatically edit the audio signal.

Means to solve problem C] A method for editing a movie audio signal according to the present invention.

The editing process edits the movie film on which continuous time codes are recorded, and the first recording process detects and records the time codes before and after the discontinuous point of the time code from the edited movie film. Based on the time code recorded in the media creation process, dubbing editing is performed on the recording medium on which continuous time code and audio signals are recorded, and the portion sandwiched between the time codes before and after the discontinuity point is A cut edited recording medium is first obtained, and then the edited recording medium is reproduced through a second recording step, and the reproduced audio signal is recorded on the soundtrack of the edited movie film.

[Effect]

The method of editing a movie audio signal according to the present invention only performs cutting editing of a movie film, and the audio signal is automatically edited based on the time code.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. Fourth
In the figure, 6 is an edited movie film, 7 is a recording medium on which edited audio signals are recorded, and in this embodiment, a magnetic tape 7 is used. In the movie film 6 and the magnetic tape 7, "01-064.rlo-13"
and "17-20" are recorded time codes.

The ID indicates the editing point. This movie film 6 and magnetic tape 7 have time codes r07~09J, r14~
16" has been removed by editing.

Therefore, unedited movie film and magnetic tape have "0"
A continuous time code of 1 to 20 is recorded.

In FIG. 1, 1 is a projector that plays back a movie film 6, 2 is a time code reader that reads the time code played by the projector 1, and 3 is a time code reader that detects discontinuous points in the time code read by the time code reader. This is a recording device that records the time codes before and after the discontinuity point.

In FIG. 2, reference numeral 4 denotes an editing device using a digital or analog audio tape recorder for dubbing and editing a magnetic tape based on the time code recorded in the recording device 3.

In FIG. 3, reference numeral 5 denotes a soundtrack recording device for recording the reproduced audio signal of the magnetic tape 6 edited by the editing device 4 onto the soundtrack of the movie film 6. Above l
The collection device 4 collects a movie film 6 to be played back on the projector 1.
Playback is performed in synchronization with the time code read by the time code reader 2.

Next, the operation will be explained. First, the first editing step is to cut and edit the movie film on which continuous time codes have been recorded before editing to create an edited movie film 6 connected by editing point IDs shown in FIG. 4. In the first recording process, the time code is read by the time code reader 2 while the movie film 6 is played back by the projector 1 shown in FIG.

The read time code is sent to the recording device 3. record bag f1
3 detects a discontinuous point in the read time code, and detects the time code before and after the discontinuous point (in the case of FIG. 4, '06J, rlo', r13').

``17'').

Next, in the recording medium production process, as shown in FIG. 2, the editing device 4 is used to dub and edit the magnetic tape on which continuous time codes before editing are recorded.

At this time, by controlling with the time code recorded in the recording device 3, dubbing of the audio signal in the portion sandwiched between the time codes before and after the discontinuous point is not performed. Therefore, the edited magnetic tape 7 edited by the editing device 4 has the portion corresponding to the movie film 6 deleted, as shown in FIG. 4.

Next, the second recording step is as shown in FIG.

The magnetic tape 6 is played back by the editing device 4, and the played audio signal is recorded as a soundtrack! 5, the audio signal is recorded on the soundtrack of the movie film 6. In this case, the time code reader 2 reads the time code obtained from the projector 1 that reproduces the movie film 6, and the editing device 4 is synchronously controlled by the read time code.

〔Effect of the invention〕

As described above, according to the present invention, dubbing editing of a recording medium on which an audio signal is recorded is performed based on the time codes before and after the discontinuous point of the time code recorded on the edited movie film. Therefore, automatic editing of the audio signal becomes possible, and there is an effect that the editing work can be greatly reduced in labor.
