How to distribute plugins for setting effects of mobile video editing tools {METHOD OF DISTRIBUTING PLUG-IN FOR CONFIGURING EFFECT ON MOBILE MOVIE AUTHORING TOOL}

The present invention relates to a business model for distributing plug-ins for video editing tools.

1 illustrates a general user interface of known video editing software for a personal computer (PC).

Looking at the general editing process of a video using such a video editing software, first select any one of the files stored locally through the file selection window as shown on the left side of the screen of Fig. 1 to load into the memory and then a part of the video Select to insert the movie clip corresponding to the selected part into the timeline.

The timeline refers to a time sequence in which the edited result of the video is rendered, and is usually displayed on one side of the screen so as to visually know the direction of time.

The user then arranges the clips at the desired location on the timeline.

A clip refers to a part of a movie temporarily created for editing.

After inserting a number of movie clips in the timeline like this, you can add subtitles, add special effects, or set a certain effect at the position where one clip ends and another clip starts. do.

These effects are commonly referred to as effects.

As such, editing a video involves arranging the positions of a plurality of clips arranged in the timeline and setting various effects for each clip or between two or more clips. You should be able to display as many clips as you can, and easily identify which effect you've set.

On the other hand, with the recent rapid spread of smartphones worldwide, such video editing software is also being produced and distributed for smartphones.

By the way, mobile devices such as smartphones or tablet computers only have slightly smaller screens, ranging from 3 to 4 inches up to 10 inches in size, so that a lot of information must be displayed on one screen. This is a very adverse environment inherently in editing.

2 illustrates a graphical user interface (GUI) of video editing software executed on a mobile developed by the applicant.

A user uses mobile to run video editing software and then create a new project. A project generally refers to an environment for editing a video.

As such, when a new project is started, the mobile displays a GUI of the video editing tool as shown in FIG. 1.

The video editing software for mobile as illustrated in FIG. 2 also includes a selection window and a timeline for selecting a video clip as in the PC environment as shown in FIG.

The user loads a locally stored video through the video clip selection window, selects all or part of the video, and drags the video to the timeline to arrange the video on the timeline.

On the other hand, after arranging the clips as described above, subtitles are added or various effects are set to one or more clips.

The process of obtaining the final video editing result by rendering is the same as the video editing software of the known PC environment.

However, a complicated operation such as accurately selecting a specific section of a clip desired by the user using a narrow screen size of the mobile, selecting a desired effect in the selected section, and setting various settings of the effect is not easy.

Therefore, unlike video editing software running in a PC environment, the editing process is simple by simply selecting a "predefined template of effects" supported by mobile video editing software and selecting one or two clips to apply it. It is desirable to be able to finish.

However, it is difficult for a mobile video editing software developer to supply an unlimited number of "templates of well-defined effects" to suit the tastes of many mobile users.

This is especially true if video editing software for mobile is free or bundled.

Therefore, it is necessary to provide an environment for end users or third party developers to easily define effects templates, and furthermore, to easily share and distribute effect templates of video editing software for mobile. have.

3 is a diagram illustrating a relationship between a mobile and a server.

The server 20 stores a plurality of plug-ins for setting the effects of the video editing tool for the mobile 10, and corresponds to a subject provided to the mobile 10 through a network.

The mobile 10 executes the video editing tool for mobile, but installs the plug-in for the video editing tool by the following three methods, and renders the effect by the plug-in selected by the user when the video editing tool is executed. Corresponds to

The first way in which the mobile 10 user installs the plug-in is to download the plug-in from the server 20 and install it in a sub path of the video editing tool.

In this case, the server 20 corresponds to a server prepared separately for the provision of the plug-in.

The server 20 provides a list of plug-ins for setting effects to the mobile 10 connected through a network, and as the mobile 10 user selects any one of them, the user can download the selected plug-in. do.

Meanwhile, the mobile 10 user selects the plug-in required by the user while looking at the list of plug-ins provided from the server 20.

The list of plug-ins preferably includes thumbnails and brief descriptions indicating the rendering result of the effect by each plug-in, and the user selects and downloads what he / she needs while installing it on his mobile 10.

The second way is for users to download the app as an app via the "Market" for Android OS or the "App Store" server for iOS.

In this case, the server 20 will be the host hosting the "market" for the Android OS or "app store" for the iOS.

The user may purchase an appropriate plug-in app through the "market" for the Android OS provided by the server 20 or the "app store" for IOS, and install it on the mobile 10.

The plug-in app is executed in the mobile 10, and as executed, copies the plug-in to a sub path of the video editing software pre-installed in the mobile 10.

The last method is a case where the user directly installs by defining a plug-in for effect setting of the video editing tool for mobile 10 and then copying it directly to a sub path of the video editing tool of mobile 10.

Meanwhile, the server 20 uploads and stores the plug-in defined by the user of the mobile 10 or the plug-in defined by the third party developer 30.

Then, a list is generated using the metadata of the uploaded plug-ins, and the generated list is provided to the mobile 10 users who need it.

Hereinafter, for convenience, a mobile of a user who directly defines a plug-in is referred to as a first mobile 11 and a mobile of a user provided with the corresponding plug-in through the server 20 is referred to as a second mobile 12.

Hereinafter, referring to FIG. 4, one aspect of a distribution method of a plug-in for setting an effect of a video editing tool for mobile according to the present invention will be described.

One aspect of the present invention shown in Figure 4 limits the process by which the mobile 10 user downloads and installs the plug-in from the server 20, and uses the plug-in installed when the video editing tool is executed.

As shown in FIG. 4, first, a user connects to the server 20 using his mobile 10 and then performs user authentication (step a-1).

For example, the user may log in to the server 20 account by inputting an ID and password.

Accordingly, when the server 20 provides a list of plug-ins for setting effects of the video editing tool installed in the mobile 10, the mobile 10 displays a list of plug-ins for setting effects of the received video editing tool on the screen. (Step a-2).

On the other hand, if the user selects any one of the plug-in from the list, the mobile 10 downloads the plug-in selected by the user from the server 20.

And, it is stored in the sub path of the video editing tool predefined according to the type of the plug-in.

For example, if the plug-in is a plug-in that defines a clip effect, it can be stored in the / sdcard / KineMaster / Effects folder.

Any plug-in that defines transition effects can be stored in / sdcard / KineMaster / Transitions.

And any plug-in that defines a theme can be stored in the / sdcard / KineMaster / Themes folder.

Subsequently, as the user selects a function of selecting a pre-installed plug-in while the video editing tool is executed, the mobile 10 retrieves metadata of each pre-installed plug-in, and displays which plug-ins are installed on the screen. (Step a-4).

The metadata of the plug-in may include a thumbnail indicating the state in which the effect defined by the plug-in is rendered, and a description of the effect. The mobile 10 retrieves the metadata to know the installed plug-ins at a glance. Mark it so you can

Subsequently, as the user selects one of the pre-installed plug-ins displayed on the screen, the mobile 10 executes the script included in the plug-in in real time so that the entire project opened in the video editing tool and the video editing tool are An effect defined by the plug-in is rendered in a section between any one clip arranged in the timeline or two adjacent clips arranged in the timeline of the video editing tool (step a-5).

In the present invention, the plug-in corresponds to a predefined effect template.

An effect means various effects that can be applied to an arbitrary clip or a section between two adjacent clips. Clip effects that can be rendered and displayed in a clip, such as subtitles, titles, or drawing shapes, and the next clip after one of the clips is finished It contains a transition effect that is set in the interval between beginnings to allow two clips to follow naturally.

Known transition effects include fade in, fade out, climb down, and zoom in from the center.

A template means data in which elements for effect setting are predefined.

A plug-in can also be a theme that is a combination of clip and transition effects that apply to the entire project.

These plug-ins define one clip effect or transition effect, or theme.

In the case of applying a clip effect, a user selects a plug-in corresponding to a clip effect from among a plurality of plug-ins installed in a predetermined path of the video editing software of the mobile 10, and then selects the clip effect among a plurality of clips arranged in the timeline. Simply select the clip you want to apply to and apply the effect defined by that clip effect to the selected clip.

In the case of transition effects, you can select a plug-in corresponding to a transition effect from a plurality of pre-installed plug-ins, and then simply switch between two adjacent clips among multiple clips arranged in the timeline. You can easily set the effect of.

On the other hand, if you look at the theme, you can apply the clip effect and the transition effect to the entire project simply by selecting the plug-in corresponding to the theme among a number of pre-installed plug-ins.

As will be described later, the plug-in has a type code, and the mobile 10 may determine whether the plug-in is a theme, a clip effect, or a transition effect according to the type code.

Hereinafter, another aspect of a method of distributing a plug-in for setting an effect of a mobile video editing tool according to the present invention will be described with reference to FIG. 5.

The present invention shown in FIG. 5 restricts a process in which a mobile 10 user purchases and installs a plug-in in the form of an app through a distribution channel of a mobile app such as "market" or "app store".

As shown in Fig. 5, the mobile 10 first accesses a server via a network by user operation and performs authentication (step b-1).

Thereafter, the mobile 10 displays a list of plug-in apps for setting effects of the video editing tool provided from the server (step b-2).

Then, as the user purchases any one plug-in app in the list, the mobile 10 downloads and installs the plug-in app from the server (step b-3).

The distribution channel of the mobile app such as "market" or "app store" is distributed in the form of an app. Therefore, they are distributed in the form of plug-in apps, not plug-ins themselves. A plug-in app refers to an app that installs a plug-in in a sub path where video editing software is installed at run time.

In general, the mobile 10 may have dual storage spaces in the main memory and the external memory. When the video editing software is installed in the main memory, the plug-in may be installed in a path corresponding to the video editing software of the external memory. .

As such, when the user executes the plug-in app installed in the mobile 10 while the plug-in app is installed, the mobile 10 copies the plug-in included in the plug-in app to a sub path of the pre-installed video editing tool (b- Step 3).

On the other hand, as the user selects the selection function of the pre-installed plug-in while the video editing tool is executed, the mobile 10 retrieves the metadata of each pre-installed plug-in so that the plug-in can know at a glance. Display on the screen (step b-5).

As the user selects any one of the pre-installed plug-ins displayed on the screen, the mobile 10 executes the script included in the plug-in in real time so that the entire project opened in the video editing tool and the video editing tool are An effect defined by the plug-in is rendered in a section between any one clip arranged in the timeline or two adjacent clips arranged in the timeline of the video editing tool (step b-6).

Hereinafter, another aspect of a method of distributing a plug-in for setting an effect of a mobile video editing tool according to the present invention will be described with reference to FIG. 6.

In the present invention shown in FIG. 6, the mobile 10 user directly defines the plug-in so as to conform to the structure of the plug-in defined by the present invention, installs it on his mobile 10, and then uploads it to the server 20. Limit the process.

As illustrated in FIG. 6, first, the user defines a plug-in for setting effects of the video editing software for mobiles having a predetermined structure, and the mobile 10 generates it in a predetermined file format (c-1). step).

At this time, the user creates a thumbnail of the effect defined by the user, and also enters a brief description of the effect.

Accordingly, the mobile 10 stores the thumbnail and description selected by the user as metadata of the plug-in.

In this case, preferably, the API function supported by the operating system is called to obtain user information (eg, an ESN, a user name, etc. of the mobile 10) and store the metadata as an metadata item.

As the plug-in is generated as described above, the mobile 10 installs the generated plug-in in a sub path of the pre-installed video editing tool (step c-2).

Then, after the plug-in is installed in this way, the user operates the mobile 10 to connect to the server and perform authentication.

Accordingly, the mobile 10 provides authentication information such as an ID and password input by the user to the server 20 to process the authentication process (step c-3).

Then, the mobile 10 provides the generated plug-in to the server according to a user's operation. In this case, the acquired user information or the user information separately input by the user is further provided to the server (step c-4).

Providing the user information in this way, when the plug-in is distributed by the server 20, counting how much is distributed or if the distribution result revenue, the amount of money to be distributed to the user of the plug-in or To indicate the author.

On the other hand, the server 20 counts the number of distribution as the uploaded plug-in is distributed, and generates distribution information including the amount to be allocated to the user by using the user information of the mobile 10 when the revenue generated according to the distribution To provide to the mobile (10).

Accordingly, the mobile 10 displays the distribution information of the plug-in received from the server on the screen (step c-5).

Hereinafter, another aspect of a method of distributing a plug-in for setting an effect of a video editing tool for mobile according to the present invention will be described with reference to FIG. 7.

The present invention illustrated in FIG. 7 is described in terms of the server 20, and describes a process in which the server 20 distributes the plug-in uploaded by the first mobile 11 to the second mobile 12.

As shown in FIG. 7, first, when a user of the first mobile 10 accesses the server 20 through a network and uploads a plug-in for setting effects of a mobile video editing tool having a predetermined structure, The server 10 stores this and updates the list of plug-ins (step d-1).

The structure of the plug-in is as described later.

Meanwhile, the server 20 provides the updated list of plug-ins to the second mobile 12 connected through the network (step d-2).

Thereafter, as the user of the second mobile 12 selects one of the lists, the server provides the selected plug-in to the second mobile 12 by a download method (d-3).

At this time, the server 20 may process the charging for the download of the plug-in to the second mobile 12.

Since the plug-in has been downloaded once, the distribution information of the plug-in is updated.

Then, the updated distribution information is notified to the first mobile 11 (step d-4).

The distribution information may further include a total selling price of the plug-in and an amount to be distributed to the first mobile 11 user.

Hereinafter, another aspect of a distribution method of a plug-in for setting an effect of a mobile video editing tool according to the present invention will be described with reference to FIG. 8.

The present invention shown in FIG. 8 is described in terms of the server 20, and the server 20 collects terminal manufacturer or carrier information of the mobile 10 connected through the network, and only the terminal of the manufacturer or carrier. A method of providing an encrypted plug-in in a decryptable form will be described.

FIG. 10C illustrates a case where an effect is applied between two adjacent clips.

This type code 110 is preferably located at the front of the plug-in 100.

When the plug-in 100 is a clip effect or a transition effect, the plug-in 100 may be formed of a root element such as <Effect />.

On the other hand, when the plug-in 100 is a theme, the type code 110 may have a root element such as <Theme />, and may have a plurality of <Effect /> elements under it.

Meanwhile, the texture code 120 defines a target to which the effect is to be rendered.

This texture code includes a texture start tag 121 as shown in FIG. Texture ID 122; Attribute directive 123; Texture attribute value 124; And texture end tag 125 in sequence.

As shown in FIG. 9,

It can be seen that the texture code 120 is displayed, such as <Texture id = "video_out" video = "1" />.

At this time, the texture start tag 121 is <texutre,

The texture ID 122 is id = "video_out",

The attribute directive 123 is video, and the texture attribute value 124 is "1".

The texture end tag 125 corresponds to />. The texture end tag should be described as </ texture>, but it can be replaced with the end slash as above.

The texture start tag 121 corresponds to a tag indicating that the texture code starts.

The texture ID 122 corresponds to a name of an object to be called by the drawing function 140 and may be arbitrarily determined.

The attribute directive 123 has one of video, src, and text.

video means the type of texture ID defined just before is video.

As such, when the attribute directive 123 is a video, the texture ID 122 may be used as a variable indicating a clip.

For example, in the example of <Texture id = "video_out" video = "1" />,

As the user executes the video editing software of the mobile 10 to select any clip on the timeline, a value or pointer pointing to the clip may be assigned to video_out.

The type or meaning of the value that the texture attribute value 124 may have depends on the texture attribute directive 123.

For example, in the case of a transition effect, if the attribute directive 123 is video, the attribute value "1" is an outgoing clip to which the transition effect is applied, and the attribute value "2" is a clip after the transition effect is applied. (Incoming Clip).

As shown in FIG. 9,

<Texture id = "video_out" video = "1" />

Two texture codes 120 are shown in sequence, such as <Texture id = "video_in" video = "2" />.

Both texture ID 122 of "video_out" and "video_in" have the attribute directive 123 as video, and have texture values of "1" and "2", respectively.

That is, if the plug-in 100 including the texture code 120 according to the example of FIG. 9 defines a transition effect, "video_out" and "video_in" are adjacent to the previous clip to which the transition effect is applied. Indicates each.

On the other hand, when the attribute directive 123 is src, it means that the type of the texture ID 122 defined immediately before is an image.

For example, <Texture id = "snowflake" src = "snowflake.png" />

In texture code 120, such as

The texture attribute directive 123 is src,

The texture attribute value 124 is "snowflake.png". That is, the name of the file can be directly input as an attribute value.

That is, when the texture attribute directive 123 indicates an image, a name and / or a path of an image file may be assigned to the texture ID 122 as its value.

On the other hand, when the attribute directive 123 is text, it means that the type of the texture ID 122 defined immediately before is text.

for example,

<Texture id = "title_text"

text = "% 1"

typeface = "asset: knewave.ttf"

textsize = "80"

fillcolor = "# FFFFFF"

fill />

In texture code 120, such as texture ID 122 is " title_text "

The texture attribute directive 123 is text, and the texture attribute value 124 is "% 1".

Attribute directives such as typeface, textsize, fillcolor, etc. that are displayed after the texture attribute value 124 are used to define the font, font size, color, etc. of the title type "title_text", and may be used or omitted as necessary. It may be.

That is, when the texture attribute directive 123 indicates text, a point variable indicating the text itself or the text dynamically input by the user with respect to the texture ID 122 may be assigned as the value.

On the other hand, according to the structure of the texture code 120 as described above, the type of the variable is defined first, and then does not assign a value to the variable.

That is, by defining the texture ID 122 first, and then describing the texture attribute indicator 123, the type of the texture ID 122 is defined later. Then, the texture attribute value 124 is described in succession. This makes the code very short and improves readability.

On the other hand, the animated value code 130 defines a value that changes with the change of time at the time of rendering the effect.

This animated value code 130 has an animated value start tag 131 and an animated value end tag 135, between which an animated value ID 132, a keyframe value 133, and a timing function tag. Has 134.

By FIG. 9

<AnimatedValue id = "fade_in">

<KeyFrame value = "0" />

<KeyFrame value = "1" />

</ AnimatedValue>

An animated value code 130 is shown.

In this case, the animated value start tag 131 is "<AnimatedValue".

The animated value ID 132 is "fade_in".

After the animated value ID 132, it can be seen that each of the two key frame tags "<KeyFrame" is defined as value = "0" and value = "1".

That is, a key frame value 133 having a value of "0" and a key frame value 133 having a value of "1" is assigned to "fade_in".

And it ends by the animated value end tag 135 "</ AnimatedValue>".

The animated value start tag 131 indicates the start of the animated value code 130.

Immediately thereafter, you define an animated value ID (132) with id = "fade_in">,

Two key frame values 133 are assigned to the corresponding animated value IDs 132.

The key frame value 133 may be one or more.

The manner in which the key frame value 133 is called by the drawing function 140 and the configuration of adjusting the change rate of the frame value 133 value by the timing function 134 correspond to the characteristic configurations of the present invention. The drawing function 140 will be described and then described again.

The drawing function 140 defines the type and method of the effect.

The drawing function 140 corresponds to a function for setting various effects that may be applied to a clip, two adjacent clips, or the entire project in the video editing software, and various functions for setting the effect may be used.

For example, various functions, such as drawing a figure on the screen, defining a transition effect between clips, or processing an effect in which a title is displayed, may be defined through the drawing function 140.

The drawing function 140 corresponds to various screen processing functions according to the known art.

Multiple drawing functions 140 may be used, and each function may have a different name and parameters.

In this case, an important point is in the manner in which the drawing function 140 calls the texture ID 122 and the animated value ID 132 to process them.

As shown in FIG. 9, it can be seen that the following two drawing functions 140 are shown.

at first,

<rect bounds = "-1 1 1 -1" texture = "@ video_out" />

to be.

"<rect" is a drawing function that draws a rectangle on the screen.

At this time, the first parameter has two coordinate values (-1,1) and (1, -1), and the second parameter has a value of "@video_out".

"video_out" is a texture ID 122 that indicates an outgoing clip as described above, and is called with @.

That is, the drawing function 140 may point to the texture ID 122 as a parameter of the function.

The animated value ID 132 can also be pointed with @ in the same way.

That is, the drawing function 140 corresponds to a code for drawing a rectangle passing (-1,1) and (1, -1) to the clip in front of two adjacent clips to which the transition effect is applied.

On the other hand, as shown in Figure 9,

<style alpha = "@ fade">

<rect bounds = "-1 1 1 -1" texture = "@ video_in" />

</ style>

A drawing function 140 is shown.

"<style alpha" is a function that sets the alpha value.

And it has "@fade_in" as a parameter.

"fade_in" corresponds to the animated value ID 132 mentioned above, and is similarly called with @.

And between <style alpha = "@ fade_in"> and </ style>

We are calling the "<rect" function once more, such as <rect bounds = "-1 1 1 -1" texture = "@ video_in" />.

The second <rect function draws a rectangle passing (-1, 1) and (1, -1) on the screen to the beginning of the incoming clip video_in.

It is important to note that "fade_in" is an animated value.

Looking back at the animated value code 130 of FIG.

<AnimatedValue id = "fade_in">

<KeyFrame value = "0" />

<KeyFrame value = "1" />

</ AnimatedValue>

Same as

This means that the start value of the animated value ID 132 "fade_in" is "0" and the end value is "1".

Then, the drawing function 140 calling the animated value ID 132 "fade_in" may draw an effect such as drawing a rectangle for a predetermined time (in the example, from the end point of the outgoing clip to the start point of the incoming clip). In processing, the value of the animated value ID 132 "fade_in" starts at "0" at the start of the effect and gradually increases to the value of "fade_in" of the animated value ID 132 at the end of the effect. Is to process the effect while changing to.

The drawing function 140 shown in FIG.

From the end of the outgoing clip to the start of the incoming clip, draw a rectangle with an RGB color value of (1, 0, 0) that fills the screen, gradually changing the alpha value from 0 to 1. Processes the effect that fades in.

That is, the code shown in FIG. 9 actually corresponds to a loop represented by the following pseudo-code.

{initial value of t = end of outgoing clip;

initial value of fade_in = 0;

while t = | start of incoming clip

{draw rectangle using alpha value = fade_in;

t = t + 1;

fade_in = fade_in + increment;}

end;}

In this case, since the time required for fade_in to be 0 to 1 and the time required from the end point of the outgoing clip to the start point of the incoming clip must be matched, more complicated coding is required to actually implement this.

However, simply defining the attributes and values of the texture ID 122 and the animated value ID 132 in a form suitable for the type and type of the effect can omit coding of such a complex loop and simply express them.

In detail about the animated value code 130,

The keyframe value 133 assigned to the animated value ID 132 is determined according to the drawing function 140 calling it or the plug-in 100 depending on whether it is a clip effect, transition effect, or theme. May vary.

In the example of FIG. 9, two key frame values 133 are assigned, the former being used as a start value and the latter being used as an end value. However, depending on the drawing function 140, one keyframe value 133 may be allocated.

In some cases, two or more values may be simultaneously assigned to one keyframe value 133.

<AnimatedValue id = "box_color">

    <KeyFrame value = "1.0 0.0 0.0" />

    <KeyFrame value = "0.5 1.0 1.0" />

</ AnimatedValue>

Assuming an animated value code 130 such as

"box_color" is the starting value of three values: 1.0, 0.0, 0.0,

The end value may have three values, 0.5, 1.0, and 1.0.

That is, in this case, "box_color" becomes a variable of the one-dimensional matrix structure having three items.

On the other hand, to improve readability,

.r = [0]

.g = [1]

.b = [2]

Predefined as

<Rect bounds = "-0.5 -0.5 0.5 0.5" color = "@ box_color.g @ box_color.r @ box_color.b" />

It may be called through the drawing function 140 as shown.

Meanwhile, the animated value code 130 may further include a timing function tag 134.

For example, when processing the fade in effect through the drawing function 140 as shown in FIG. 9, if the value of the animated value ID "fade_in" varies linearly from 0 to 1, The problem is that the beginning and the end are not smooth and feel awkward.

The timing function tag 134 adjusts the rate of change of the value assigned to the animated value ID 132 by using a cubic bezier function to solve the problem of the linear interpolation.

The timing function tag 134 is located after the animated value start tag 131 and before the animated value end tag 135.

In other words, the important point is that the timing function tag 134 is not defined through the drawing function 140 but is part of an attribute of the animated value ID 132.

This structure also allows the user to simply set the rate of change of the keyframe value 133 assigned to the animated value ID 132 without coding a separate complex loop.

The timing function tag 134 may be expressed through a tag such as, for example, <TimingFunction /> or <Const />.

On the other hand, this timing function tag 134 preferably has a parameter consisting of four consecutive numbers.

In this case, the four consecutive parameters represent the coordinates of the control point of the Bezier function for adjusting the change rate of the keyframe value 133 assigned to the animated value ID 132.

The first parameter, the first parameter, is the x coordinate of the first control point, the second, the second parameter, the y coordinate of the first control point, the third, the third parameter, the x coordinate of the second control point, and the last, fourth parameter, the second. Points to the y coordinate of the control point, respectively.

For example, if the parameter is 0.25 0.10 0.25 1.00, a Bezier curve with two control points (0.25, 0.10) and (0.25, 1.00) can be drawn.

At this time, the start point of the Bezier curve is (0,0) and the end point is (1,1).

FIG. 11 illustrates an example of a cube Bezier function for implementing a timing function. FIG. 11A illustrates a Bezier curve when 0.25 0.10 0.25 1.00.

The x-axis is time-varying, and the y-axis is the keyframe value 133 value assigned to the animated value ID 132.

In other words, the value of the key frame value 133 gradually increases at the start and gradually increases at the end.

The beginning and end of the animation will slowly start and end.

FIG. 11B shows the Bezier curves when four parameters are 0.42 0.00 1.00 1.00.

In this case, the animation starts slowly, but ends linearly.

FIG. 11C shows a Bezier curve when four parameters are 0.00 0.00 0.58 1.00.

In this case, the animation starts linearly, but slowly ends.

(D) of FIG. 11 shows the Bezier curve when four parameters are 0.00 0.00 1.00 1.00.

In this case, the animation starts linearly and ends linearly.

The keyframe value 133 increases linearly and uniformly.

Meanwhile, the coordinate system conversion code 150 may be further included before calling the drawing function 140.

The coordinate system conversion code 150 has a projection code 151, an aspect ratio extension code 152, and an origin movement code 153.

The coordinate system conversion code 150 is, for example, as follows.

<projection type = "perspective" aspect = "1.777777" fov = "45" near = "0.01" far = "60000">

<translate offset = "-640 -360 -870">

<-drawing function 140->

</ translate>

</ projection>

The projection code 151 projects the coordinate system into a three-dimensional coordinate system having a z axis.

At this time, the angle from the viewpoint (Veiwpoint) can be set.

The aspect ratio extension code 152 extends the coordinate system to fit the aspect ratio defined by the number of pixels in the aspect of the display on which the video editing tool is displayed.

In the <projection type = "perspective" aspect = "1.777777" fov = "45" near = "0.01" far = "60000"> code (151, 152),

Project in a 3D coordinate system like <projection type = "perspective"

By setting fov = "45", the angle at the view point is 45 degrees.

Then, by setting aspect = "1.777777", the one-to-one ratio coordinate system is extended to fit the mobile screen's aspect ratio 1.77777. As a result, each pixel may have a square shape, and shape distortion due to an aspect ratio may be removed when rendering the effect by the drawing function 140.

<translate offset = "-640 -360 -870"> The code 153 moves the origin of the screen center to one end of the 720p coordinate system. And, moving by 870 in the z-axis is to prevent the object of the z = 0 plane is not displayed in the field of view.

Meanwhile, after the projection code 151, the aspect ratio extension code 152, and the origin movement code 153, the drawing function 140 is called in the <-drawing function 140-> part.

Thereafter, the origin movement code 153 is terminated through the </ translate> tag, and the projection code 151 and the aspect ratio extension code 152 are terminated through the </ projection> tag.

Such coordinate system conversion code 150 is not necessarily included in the plug-in 100, such as the type code 110, texture code 120, animated value code 130 and the drawing function 140,

By including the drawing function 140 before the call, the distortion of the object due to the screen aspect ratio during rendering of various drawing functions (eg, screen rotation) may be prevented.

Therefore, even when the 3D effect is not used, it is preferable to include the coordinate system transformation code 150 before the drawing function 140 is called.

The method of distributing the plug-in for setting the effect of the video editing tool for mobile as described above may be implemented in the form of a computer-in particular, a software which is a set of instructions that can be read by a mobile, and may be recorded on a recording medium.

In this case, the recording medium may include any type of medium readable by a computer, such as DVD-ROM, CD-ROM, hard disk, USB memory, and flash memory.

On the other hand, the expression to be recorded on the recording medium includes not only the case of being recorded on the recording medium of this type but also the case of being provided through a communication line in the form of an intangible carrier wave (Carrier Wave).

While the present invention has been described with reference to the accompanying drawings and embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. .
