Setting Events




Event

The purpose of the five layers at the bottom of the Timeline window is to add various events to an item of content. When the current frame enters the section in which the event is set, the event is started.

To set or define an event, click an appropriate frame on the layer appropriate for the type of event that you wish to insert, and drag along the timeline so that a blue band appears on that layer. To remove a blue band, drag one end of the band to the other. This operation method is the same as that for "Editing the effective section."

For jump, audio, and link events, you can specify a delay time (milliseconds). When a value greater than 0 is set for a delay time, the events actually occur after the set time. However, the delay cannot be longer than the duration of the frames for which the event is specified; otherwise the movie will continue without the event occurring. Use these events when you wish to display a page after a fixed time.

To check the operation of an event, select Play mode () from the tool bar to preview it in the main window. Note that an event does not occur in Edit mode ().




Autoplay

If the current frame enters the set section (blue band) when the content is being operated on, the section is automatically played.

The play speed is set in the autoplay event palette. Specify a value in milliseconds (one second = 1,000 milliseconds) in [Frame interval]. Specifying a value of 0 plays the section at full speed.

When [Interruptible] is ticked, the user can interrupt play during autoplay and operate on the drag path by clicking or dragging the mouse cursor.

Example of behavior

When the blue band is reached,

the section is automatically played up to the last frame.




Jump

If the current frame enters the set section (blue band) when the content is being operated on, the play jumps to the jump destination frame (after any set delay time). Remember that the current frame must still be inside the section at the end of the delay time, or no event will occur.

Pressing the [Add] button in the jump event palette adds the current frame to the jump destination. On the timeline, the jump destination frame is marked with a solid red circle.

To delete the jump destination, select the frame to be deleted and press the [Delete] button.

You can specify multiple jump destinations. You can also specify the same frame a number of times.
If you have specified multiple jump destinations, then the jump choice is random. Use Jump when you create content where a lottery is held, for example.

Example of behavior

When the blue band is reached,

the play jumps to the specified frame (marked with a solid red circle).




Audio

When the current frame enters the audio event section, an audio file is played (after any set delay time). Remember that the current frame must still be inside the section at the end of the delay time, or no event will occur.

When you press the [Open] button in the audio event palette, the dialog box for opening an audio file appears to enable you to set the audio file.

The audio file supports WAV and AU file formats. Audio is converted to 8-bit 8-kHz monaural in accordance with the JAVA applet specification.

When [Repeat] is ticked, audio is continuously played while the current frame stays within the blue band.

Example of behavior

When the blue band is reached, audio is played.




Link

When the current frame enters the link event section, the page specified in the [URL] field is displayed (after any set delay time).
Remember that the current frame must still be inside the section at the end of the delay time, or no event will occur.

You can specify the window/frame in which the page is to be displayed in the [Target] box.

* The word "frame" is used here to refer to a window of a Web browser which is divided into multiple areas.
Note that this differs from a time "frame" indicating a frame in a video in the timeline window of DRAGRI.

The settings in the [Target] box are as follows:

user or any name

If the window of a web browser is divided into frames, you can specify the name of a frame, so that the webpage is displayed in that frame.

Alternatively, if JavaScript is used to open a window of a web browser with the window name specified, that window name can be specified in order to display the specified file in that window.

_selfThe webpage is displayed in the same frame as the content.
_parentThe webpage is displayed in the parent frame.
_topThe webpage is displayed in the top frame.
_blankThe webpage is displayed in a new window.
javascriptJavaScript function is executed. [Details]
loadOther content is loaded and substitutes the current content. [Details]

Example of behavior

When the blue band is reached, the specified Web page is displayed.

You cannot check this event under the control of DRAGRI. By playing the generated content using a Web browser, you can check the behavior.




Configuration

The direction and speed of Autoplay can also be specified.

When the current frame enters the set section, the speed and direction of play are changed according to the configuration.

Direction of Autoplay

Enter

$play_dir=n;

in the [Autoplay Parameter] field of the Autoplay information palette, (which appears when you click a frame on the Autoplay layer).

If n = 1, the video is played normally. If n = -1, it is played in reverse.

If n = 2 or 3, the play becomes 2 times or 3 times faster. Only integers are allowed.

Play speed

Enter

$play_speed=n;
in the parameter part.

The value of n should be relative to the play speed of the frame play interval set in the Autoplay information palette, expressed as a percentage.

If n=200, the speed is double. If n=50, the speed is halved.

Example of settings

Assume that the timeline and event are set as shown below, which will make the second half of video1 play automatically after dpath1 has been dragged.

[Configuration] is set for the last frame of video1. As shown on the right, the configuration settings are "$play_dir=-1; $play_speed=200;".

In this setting, the direction of play is reversed and the play speed is doubled.

When autoplay reaches the last frame, the play is reversed at double speed.
