Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a VTR editing system that can effectively perform videotape editing on a VTR.

(Prior Art) Videotape editing in a VTR is mainly performed by performing assembly processing and video insert processing for a plurality of videos. Such editing work is carried out by exclusively determining in-timings and out-timings for various videos, and performing video switching processing in accordance with these timings.

However, in the case of a dedicated VTR editing device, for example, the above-mentioned in timing and out ◆ timing may be registered in advance in its control unit, and video switching may be controlled automatically according to these timing information. VTR
Edits have been performed. However, the above-mentioned timing information for realizing such VTR editing is generally only given as a series of numerical data. For this reason, it is essentially impossible to understand the editing content from this timing information.

Conventionally, countermeasures have been taken, such as writing down an address value that indicates the location of the video on the video tape that is the material for editing, along with the so-called storyboard, and referring to this to understand the editing content. ing.

However, editing work on a VTR is often carried out on a trial-and-error basis, and in most cases, editing is not performed as specified on the storyboard. For this reason, the reality is that each time there is a change in an editing item, the editing flow is corrected on the storyboard, and then the timing information mentioned above is corrected while referring to the corrected storyboard. . Therefore, it cannot be denied that the editing work requires a great deal of effort and time, and there is a problem in that the efficiency of the editing work is very low.

(Problem to be Solved by the Invention) Conventionally, in the past, the address value indicating the location of the image on the videotape, which is the material for editing, is written down in the storyboard, and while referring to this address value, the VTR is edited.
As videotape editing work is progressing,
For example, if there was a change in the editing timing, it was necessary to revise the storyboard and check the contents each time, so it is undeniable that the editing process requires a great deal of effort and time. There was a problem that the editing work efficiency was very poor.

The present invention has been made in consideration of such 7J ■ circumstances, and its purpose is to provide a VTR that allows editing processing to be carried out easily and efficiently while grasping the content of the video to be edited. Its purpose is to provide an editing system.

[Structure of the Invention] (Means for accomplishing the problem W(i)) The VTR editing system according to the present invention creates an editing list corresponding to a storyboard as an electronic file, and stores a videotape as a material for editing in this editing list. This is characterized in that the address value indicating the video recording position and the description indicating the content are linked.

Furthermore, by using an image memory that stores a part of the video recorded on the videotape that serves as the material for editing, edit the part of the video stored in this image memory by linking it to the corresponding item in the edit list. It is characterized by being used for.

(Function) According to the present invention, in the edit list converted into an electronic file,
The address value indicating the video recording position on the videotape, which is the basis for the editing, and the description indicating the content, as well as parts of the video are linked, so the content can be determined in the editing process, which is done by trial and error. Even when changing the description or the address value indicating the video recording position on the videotape, it can be easily rewritten on the linked electronic file. As a result, it becomes possible to efficiently proceed with the editing work while checking the edited content on the electronic file.

(Example) Hereinafter, with reference to the drawings, a V T according to an example of the present invention will be explained.
The R editing system will be explained.

FIG. 1 is a diagram showing a schematic configuration of an embodiment system, in which 1 is a playback VTR used for sending out images from a videotape that records various images to be edited;
is a recording VTR that records various edited videos.

The control unit 3 controls the operation of each of the VTRs 1 and 2 according to editing control instruction information given from a human power unit 4 such as a keyboard, and an editing list stored in an electronic file in an editing work list file 5 in advance. , and also controls the import of video and performs editing work.

It should be noted that the video used for editing is not only taken in from the above-mentioned playback VTR 1, but also taken in from the T.
In some cases, the image may be directly captured from a V camera, image scanner, or the like.

The control unit 3 extracts a part of the video captured from the reproduction VTRI, that is, a part of the video representing a representative part of the video content, and converts the extracted video to the A/D converter 6. The image is digitally converted and stored in the image memory 7. Regarding the image information stored in this image memory 7,
It is also possible to create a so-called picture-story show-like image by compressing several still images instead of a single still image.

The image information stored in the image memory 7 in this manner is used as file information corresponding to a storyboard, and is managed by being linked to the corresponding item in the editing list, as will be described later.

The video information stored in the image memory 7 is read out by the control unit 3 as needed, converted into the analog signal form below via the D/A converter 8, and then displayed on the TV as a still image etc. It is displayed on a display section 9 consisting of a monitor or the like. Further, under the control of the control section 3, the display section 9 reads out and displays the information of the edit list, which has been previously stored as an electronic file in the edit work list file 5, as necessary.

The essential difference between this system, which is basically configured as described above, and conventional systems is that the edit list used for video editing is converted into an electronic file and stored in the editing work file 5, and is stored in the image memory 7. The main point is that it is managed in a way that is linked to the image information provided.

That is, the edit list is here a tape item list,
It consists of three types of lists: an editing summary list and an editing work list, which are linked to each other.

The tape item list is shown in A1. of Figure 2. As shown in A2, it is a record of the contents of various videos recorded in pieces on multiple video tapes. For example, for rTAPEIJ, see "Introduction".
``Introduction'' Information indicating that video information regarding ``scanner input'' is recorded is described. An item content file B1 is linked and provided for each of these items, and detailed item information regarding each of the video information is described in this item content file B1.

In this example, the information related to "Introduction" recorded in rTAPEIJ includes address information "Start;2HIMO84PJ" indicating the recording position of the video on the videotape.
r End; 2H2M2SOPJ and r memo regarding its information content, and furthermore, the ``file name'' of the image stored as an image file in the image memory 7 described above regarding the video are described as detailed item information.

A file describing such information is linked and provided for each item in the tape item list mentioned above.
The information content is now managed as an electronic file. Therefore, the videos to be edited are listed in the tape item list A1. A2... When specified above, information about the content is obtained from the item content file Bl... and can be monitored as appropriate on the display section 9.

On the other hand, the editing summary list C is created as information indicating the contents of the editing process, as shown in FIG. 3, for example. This editing work list C shows the flow of images on the videotape that will be finally edited and produced. That is, this editing summary list corresponds to a so-called table of contents on video software, and represents information indicating the flow of videos when a plurality of videos are edited. With such an editing summary list C, for example, as shown in FIG.
, r editing function'', etc. In particular, the video contents of the above-mentioned ``editing function'' are shown to be expanded according to the items ``still image manual input'', r moving image input'', and so on. Furthermore, regarding the above-mentioned "still image manual power", there is an information item called "scanner manual power"...
It is shown that "Video input"... is expanded by the information item "Camera manual power"....

Such an editing summary list C is created, for example, by directly using table of contents information created using a word processor. For each item in this editing summary list, the corresponding item in the tape item list A mentioned above is
For example, they are linked as shown in FIG. 2.

Another editing list, editing work list D, is configured as shown in FIG. 4, for example. This editing work list D consists of information that sequentially describes the operations at the actual editing stage in the VTR system. This information is given as information that describes how the editing information such as the following is edited. In other words, in addition to editing information that shows the connections between content information about multiple videos that are given as editing materials piecemeal, there is also special effect information about how these videos are joined together, and the An editing work list D is configured as information describing how information such as audio and music to be edited along with the editing is edited in relation to the video.

Information of such editing work list D is displayed on the display section 9,
For example, the edited content is presented to the operator (editing worker) by displaying it in the form of a diagram.

1 Three types of editing lists configured as described above, namely, tape item list A2 editing summary list C1 editing work list D
are mutually linked between corresponding items on the digitized file,
closely associated with each other. and the display section 9
The control unit 3
The video is subject to automatic editing control under the control of.

Here, video editing work based on the above-mentioned editing list will be explained using a specific example.

For example, assume that the contents of a report are edited and created on a videotape and then displayed and explained using a VTR. In this case, if a report has already been created, the table of contents information in that report is used as is as the editing summary list C. The editing work for the video begins with the editing summary list C created (obtained) in this way.
For each item in the table of contents mentioned above, map the video you want to use there using the tape item list A mentioned above,
Link the video to each editing item.

At this time, an editing work list D is created according to the editing summary list C, and information indicating how the videos to be edited are to be combined is obtained.

Then, according to the information shown in the file B described above, correspondence is also made with image files showing typical contents of each video.

As a result, the videos that will be the materials for editing are arranged in chronological order on the electronic file according to the editing summary list C, and information about the videotape on which each video is recorded and the recording position on the videotape is also displayed. Each will be required.

The control unit 3 sequentially reads out the videos shown in the editing list by controlling the operation of the playback VTRI in accordance with the information shown in the editing list, and transfers them to the recording VTR.
I will be editing and recording on Z.

However, as it is, the video is simply edited to connect the video, and it is extremely difficult to include audio or music to accompany the video. Furthermore, even if the editing order is changed or the display time of each video is changed, it is very difficult to visually check the editing effect at the editing processing stage.

Therefore, in this system, according to the editing work list D, the contents of the editing work list D are visually displayed, for example as shown in FIG. Synchronization information and various control information for realizing special effects can be programmed. And this visually displayed editing work list D
From the content of the video, it is possible to check (understand) the format in which the editing work is proceeding and what kind of video software will be ultimately created.

According to this system configured in this manner, even when editing a video on a VTR by making corrections to the editing items by trial and error based on a pre-created editing work list, the editing process can be easily performed. While visually checking the contents using the editing work list D, the editing work can be performed while checking the editing effect. Moreover, since the edit list is built on the electronic file,
In most cases, the correction can be made simply by changing the link on the electronic file. Therefore, video editing processing can be carried out efficiently without using storyboards and rewriting the information as in the past. In addition, by reading out images linked to editing items in the editing list from the image memory 7 and displaying them, it becomes possible to proceed with the editing process while accurately grasping the contents of the video to be actually edited. .

As a result, by controlling the operation of VTRs 1 and 2 according to the editing work list D that has undergone editing processing, and proceeding with the video editing work in the VTR system according to the information in the editing list converted into an electronic file, the desired flow can be achieved. It becomes possible to efficiently edit and create video information (video software).

Note that the present invention is not limited to the embodiments described above. Although an example has been described here in which the editing process is performed mainly based on the video obtained from the videotape, the editing process can be performed in the same way when other video information is used. Further, the format of the edit list, the description format of the information content 5 described therein, the display format of the edit list, etc. may be determined according to the system specifications. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.

[Effects of the Invention] As explained above, according to the present invention, an edit list is constructed as an electronic file, and each item of the edit list shows information such as the recording position and the content of the information regarding the video that is the material for editing. Information etc. are linked and managed, and if necessary, representative video information is also linked and managed.

After performing trial-and-error editing work on this electronic file edit list while visually displaying the editing contents, the actual video is edited according to the edit list. . As a result, it has a great practical effect, such as being able to efficiently proceed with editing work and execute video editing on digitized files without managing video content using storyboards as in the past. It can be played.
