ELAN supports the following options for navigating through a document:
accessing points in time (the section called “Accessing points in time”);
going to a selection (the section called “Going to the borders of a selection”);
jumping step by step through a document (the section called “Jumping step by step through a document”);
navigating using the Timeline Viewer (the section called “The Media Player options”)
navigating using the Grid Viewer (the section called “Viewing a list of annotations within one tier (Grid Viewer)”);
navigating using the Interlinear Viewer (the section called “Jumping from annotation to annotation (Interlinear Viewer)”).
All Viewers are synchronized in time, i.e., when you navigate to a specific point or selection in one Viewer, all other Viewers will immediately jump to the corresponding point or selection:
The Video Viewer will display the corresponding video frame
The Waveform Viewer will display a crosshair at the corresponding location in the waveform.
The Subtitle, Timeline and Interlinear Viewers will display the corresponding annotation(s).
To access a point in time, do one of the following:
Use the timecode box.
Click on the timecode above the media playback controls (left side of the ELAN window). The
dialog window appears.Enter the timecode in the following format: “hh:mm:ss.sss” (hours:minutes:seconds.milliseconds). The crosshair jumps immediately to the selected timecode.
You can omit part of the timecode information:
If the digits are “00”, you can omit “hours:”, “hours:minutes:”, or “hours:minutes:seconds.”
It is optional to specify “.milliseconds”.
The character preceding the milliseconds is a dot, not a colon.
Use the crosshair
Click somewhere in the Text, Subtitle, Timeline,
Waveform or Grid Viewer. The crosshair will jump to that
point. By holding the ALT button and dragging
the time axis to the left or to the right you can scroll
through the annotations.
Use the media control buttons
If you have made a selection (see the section called “How to make a selection”), you can move the crosshair to the begin or end of that selection from anywhere within the file.
To jump to the begin, click on the button, which is part of the Selection
Controls. Then the button will show an arrow in the other direction
, which brings the crosshair to the end of the
selection.
It is possible to move the crosshair back and forth step by step. To achieve this, use one of the media controls as described in the section called “The Media Player options”.
If the media framework Elan is using cannot determine the video format, you can alter the step size when using the next/previous frame control. This is useful in order to work with a “natural” frame duration, depending on the video format that is used (i.e. 25 frames/second for PAL or +/- 30 frames/second for NTSC).
Do the following:
Click on
menu.Go to
. The following menu appears:
Select an option from the menu:
: The 1 frame stepsize for video data corresponds to one PAL frame (40 ms)
: The 1 frame stepsize for video data corresponds to one NTSC frame (33 ms)
Click on a Frame Length mode to select it. A radio bullet appears next to the selected step mode.
ELAN allows you to list all annotations from a single tier, and then select one annotation and jump to it.
To activate the Grid Viewer, click on the
tab:
The structure of the
window is as follows:
You can change the Grid Viewer’s interface at any moment
by right clicking in the Grid Viewer. A context menu will
appear:
In this context menu, you can choose between the
following options:
choose the columns displayed in the Grid Viewer
changing the Grid Viewer’s font size
toggle between the time code format (hh:mm:ss.mmm) and milliseconds
You can use the
window to navigate to an annotation in the ELAN window. You have the following two options:Move the crosshair to the begin of an annotation.
Do the following:
In the
window, click with the mouse button on an annotation.A red triangle appears next to the annotation in the
window, and the crosshair moves to the beginning of that annotation in the ELAN window.Select a time interval.
Do the following:
In the
window, click with the mouse button on the first annotation that you want to select.Keep the mouse button down and drag the mouse to another annotation.
In the
window, all selected annotations are highlighted in light blue color. In all other windows, the corresponding time interval is selected and highlighted in light blue color (starting with the beginning of the first annotation and ending with the endpoint of the last).Selecting a time interval also changes the current time. This happens implicitly by moving the crosshair to the begin of the annotation.
In the Interlinear Viewer, you can jump from one annotation block forward/backward to the next block. Do one of the following:
Click on the left arrow button at the top of the Interlinear Viewer to move to the previous annotation block.
Click on the right arrow button at the top of the Interlinear Viewer to move to the next annotation block.
