The file input unit automatically classifies and inputs a multimedia file selected by a user according to a media type including a moving picture, a still picture, and a sound based on a link between a media subtype and a file extension. The clip extractor supports preview of the multimedia file input by the file input unit, and extracts a multimedia clip by selecting all or part of the multimedia file. The effect selector presents an editable effect applicable to the multimedia file input by the file input unit, and selects an edited effect at the request of the user among the edited effects. The time axis arranging unit sets at least one multimedia clip extracted from the clip extracting unit according to a user's drag operation to set a play time and a media type as a first axis and a second axis, respectively. By arranging at the desired time position of the axes, at least one or more multimedia clips are played simultaneously according to the media type. The superimposition effect generation unit generates a superimposition effect such that the multimedia clip has a superimposed edit effect at the time of reproduction by arranging at least two or more edit effects selected from the effect selector to overlap at a desired position of the first axis.

The video editing system may further include an effect storage unit for separately storing an effect selected by the effect selecting unit to facilitate reselection.

The video editing system may further include a property changer configured to display a pop-up window for changing the property when selecting a target for which the property is changed to change the property of the arranged multimedia clip and the editing effect.

Hereinafter, an example of implementing the video editing system 100 of FIG. 1 will be described in more detail with reference to the accompanying drawings.

2 to 8 are images illustrating an example of implementing the video editing system of FIG. 1.

The file input unit 110 is a means of importing a work target of the video editing system 100 according to the present invention. As shown in FIG. 2, a file selected by a user is automatically classified and posted according to the media type.

In the classification method of the present invention, the internal media subtypes of the files are analyzed, the association between the media subtypes and the file extensions is verified, and the video file, the still image file, and the audio file are automatically classified to separate areas on the edit screen. Place it in

The media subtypes in the file are JPG, GIF, BMP, WMV, AVI, and MP3 files that are typically used. For example, if the extension is a JPG file, the media subtype is RGB24. If the type is ARGB32 and the extension is a BMP file, the media subtype is RGB24.If the extension is a WMV file, it depends on the WMV encoder version, but the video media subtype is WMV2 and the audio media subtype is WMAudio V8. Is an AVI file, the media subtype is Avi, and if the extension is an MP3 file, the media subtype is PCMAudio.

Each file has various media subtypes, but the information about this part is loaded into the video editing software to compare the media subtype and the file extension for the loaded file. As a result, they are classified and placed in separate areas on the edit screen.

In fact, an error may occur when playing multimedia files by giving an extension that does not match the media subtype, so the software first filters the error using the linkage between the media subtype and the extension.

By dividing video files, still image files, and audio files to be used for video editing into separate areas on the editing screen, users can prevent errors in the use of inserting still images or audio in place of the video. For smooth video editing, the video editing can be reviewed or compared with each other by reproducing the resources to be used for video editing within the same category, making the video editing process faster and easier for the user.

Files classified in the above manner can be easily moved to the display window by selecting drag or double-clicking, for example, so that preview and section setting can be performed.

3 is an image for explaining an edit screen displayed by the video editing system 100. In the display window located in the form of a large screen on the left side, the multimedia file loaded by the file input unit 110 is a video file, a still image file, and an audio file, respectively. Is automatically classified into the photo region of the clip extractor, and the audio file is automatically classified into the background music region of the clip extractor. Such automatic classification may be performed by using the linkage of the internal media subtype and the file extension of the above-described files.

In addition, the multimedia file may be previewed by double-clicking or dragging the mouse. For example, the multimedia file may be cut by selecting a section required for editing. In this case, the above operation may be performed by the operation button 21. The cut multimedia files are sequentially arranged on the right side of the original file with the multimedia clip 22, so that several source files can be easily distinguished.

In particular, the present invention enables the application of media of various sound sources by allowing the editing of the sections of music and sound. In other words, the software can not only use the music file as a background sound, but also has the advantage of extracting and using various sounds (applause, car sound, etc.) in the video. Likewise, if the audio part of the video file can be used, the audio part of the video file has a musical part, a human voice, and an acoustic part such as a clap or a car sound. have.

Meanwhile, the multimedia files selected by the user are automatically classified and sorted on the screen based on the linkage between the media subtype and the file extension. When the user simultaneously selects a video file, a still image file, and a music file through the file input unit 110, the video file is automatically positioned in the video region, the still image file is positioned in the photo region, and the music file is It can be located in the background music area. In addition, the multimedia source and the multimedia clips extracted from the multimedia source are located on the screen.

4A and 4B are images for explaining an edit window displayed by the video editing system 100. The edit window may be composed of a time axis 31 and a media type 32. In order to edit the file to be edited and the effect and sound to be applied to the video by arranging the time axis 31 on the x-axis and the media type 32 to be played by the corresponding time on the y-axis, Arrange to complete the edit.

As illustrated in FIGS. 4A and 4B, the time axis arranging unit 140 includes a file selected through the file input unit 110, the clip extractor 120, the effect selector 130, and the effect storage unit 160. And by dragging and arranging effects on the time axis of the corresponding media, various media are sequentially played based on the time axis. It is possible to arrange. In particular, video effects and text effects (letter editing effects) have a technical feature (3-a), which is designed to be superimposed in one track so that multiple effects can be applied at the same time.

In other words, if a user wants to add a specific effect to a video obtained through a camera or the Internet, i) select a time axis section ii) select media such as a video, still image, sound file, and effect to be played back iii) the selected media To arrange by dragging on the time axis according to the corresponding type.

In this case, the effects may be superimposed on the same time axis in step iii), and various effects may be generated by overlapping effects.

For example, if you want to add a balloon frame effect in a visual effect, you can put this effect on top of the time axis along with other effects so that two or three effects can be applied simultaneously.

Although the balloon frame effect is reflected in a specific section of the video selected by the user, if you want to add an additional heart animation effect in the video effect group together with the balloon frame effect, select this effect and put it in the same section.

Since various effects selected as above can be applied simultaneously to a specific section of a video, they can be used in various combinations of the provided effects.

In other words, the user can create an AB effect using the A and B effects in a specific effect group.

The video editing system of the present invention can support more various effects with a small number of effects using a superposition arrangement of effects. If there are three effects, A, B, and C, there are seven possible combinations of effects: A, B, C, AB, AC, BC, ABC.

For example, when the editing effect includes a first editing effect and a second editing effect, the overlapping effect generator 150 may include a resolution calculator, a size position calculator, and a pixel value converter.

The resolution calculator calculates a resolution of an applied image of the multimedia clip.

The size position calculator calculates a relative size and position to which the editing effect is to be applied, corresponding to the resolution of the applied image.

The pixel value converting unit includes a pixel value converting unit converting a pixel value of an applied image to which the editing effect is applied to a pixel value to which the editing effect is applied, and starting from a start frame to which the editing effect is applied when the applied image is a video. The pixel value of the frames is converted by calculating the number of frames up to the end frame.

In this case, the overlapping effect generating unit 150 may apply the second editing effect by considering the image to which the first editing effect is applied as the applied image after applying the first editing effect.

The detailed description to enable overlapping arrangement of effects is as follows.

The effect has a still image form and is overlapped in the form of a mask on a moving image or still image (hereinafter referred to as an "application image") to be applied. The method to apply the overlapping arrangement of effects is 1) calculating the resolution of the applied image, 2) calculating the relative size and position of the effect according to the resolution of the applied image, and 3) applying the effect in the form of a mask to the corresponding position of the applied image-mask The shape is the pixel value of the applied image to which the effect is to be converted into the pixel value of the effect. 4) If the applied image is a movie, the number of frames from the start frame to the end frame to which the effect is applied is calculated and 5) Convert the pixel value to the pixel value of the effect.5) If another effect is applied to the applied image to which the effect is applied previously, consider the applied image as the applied image and convert the pixel value of the image to the pixel value of the effect to be applied. do.

By using the above method, two or more effects can be applied to the same position continuously. Since the technique used for the effect superposition of the present invention records only the names and the order of the effects applied to the applied image, it has the advantage that only a small amount of memory is required in addition to the memory occupied by the applied image even when many effects are superimposed. This advantage is the key to the effect nesting.

5 is an image for explaining various editing effects that may be employed by the video editing system 100.

Referring to FIG. 5, a variety of effects are used for video editing by the video editing system 100 as well as existing video files, still image files, and audio files.

Effects provided in the embodiment of FIG. 5 are a speech bubble effect, a news subtitle effect, a title effect, a video effect, a frame effect, an animation effect, a transition effect, an opening / ending effect, etc., which can be applied indefinitely for each directory.

To make video editing faster and easier, the basic materials used for video editing should be selected: video files, still image files, audio files and various effects.

As shown in FIG. 5, according to an exemplary embodiment implemented by the video editing system 100, the provided effects are largely a text editing effect, a video effect to which an image may be applied, and a switch applicable to a video change. It is configured to select and classify effects and effects to be included in the opening and ending images.

When the video effect is selected, various effects that can be shown are arranged. The user simply selects an effect to be applied to the image by clicking or dragging and previews on the display window to determine whether to apply.

The effects provided by the present invention are provided in a completed state that can be directly applied, so the user does not need to modify the effects themselves, and simply selects or superimposes them, so that even a beginner without video editing experience can easily produce various effects.

6 is an image for explaining an implementation example of the effect storage unit 160 of the video editing system 100.

Editing effects are provided in the form of dozens for various requirements of the user, but the number of effects that the actual user uses for video editing is often limited to a few.

However, in the conventional system, it is inconvenient to select a particular effect among many provided effects and apply it to video editing, and then re-search from the beginning to apply the same effect again.

In order to eliminate such inconvenience, the present invention uses the effect storage unit 160 to form a clip region in each of the effect regions as shown in FIG. Place only the effects to be used in the clip area.

This eliminates the need to rescan many of the effects provided for reapplying after applying a particular effect to the video edit, increasing the concentration of the video edit and completing the video edit in a short time.

7 is an image for explaining a property window implemented by the video editing system 100.

In the process of finally editing various files and effects that have already been individually edited by the property changing unit 170 through the time base arrangement unit, when a property of a file or effect is to be changed later, By clicking and selecting to display a popup window that can change the properties, it is possible to efficiently perform the property change work after arranging on the time base.

8 is an image for explaining a function of uploading a video generated by the video editing system 100 directly on the Internet.

There are two main purposes for users to edit videos. The first is when the user saves the edited video on his computer, and the second is when the user uploads the edited video files to the sites that are registered as members among many User Created Contents (UCC) sites.

Referring to the second case based on the conventional video editing system, the edited video file is stored in the user's computer, and then accesses the UCC site registered as a member, and uploads the edited video according to the upload procedure of the site. This consumes a lot of preparation time for uploading as well as the actual time used to actually upload. In this case, of course, the procedure also requires inconvenience.

As shown in FIG. 8, the present invention stores the video file edited through the storage unit 180 and at the same time logs in to a designated Internet site and immediately uploads the file. The function of the storage unit 180 as described above enables the present invention to provide an upload service by connecting to a specific Internet server.

That is, the video editing system 100 allows the user to download from the site (UCC site) to which the user is registered as a member and the user edits the video using the downloaded system and uploads it directly to the corresponding UCC site. Can be used to automatically save the computer.

9 is a plan view illustrating a keyboard of the video editing system 100.
