Working in 2D mode

MatchMover provides you with the ability to open different views within the Workspace window to study and manipulate the image sequence and the results of the tracking process.

When you load a sequence, the default view is the 2D View. The 2D View is designed to display single images, image sequences and tracking information to help in your 2D tracking task. The following list shows all items that are drawn in the 2D View:

Images, helper images and matte sequences.
The current and local times of the frames in the upper left corner.
Masks. See Identifying image regions.
Camera Anamorphism, expanding the view to fit the anamorphic camera settings.
Tracking information.
- 2D Tracks, showing the position of the point in one frame. 2D tracks can be displayed using the default cross-hairs or in pattern mode. You can customize the display by selecting Preferences > Display > 2D Mode.
- Point Labels, showing the point name.
- Track Paths, showing the displacement of the point between frames. The track paths are displayed either in a uniform color or using different colors, depending on current track frame quality, from poorest (red), to best (green). You can customize the display by selecting Preferences > Display > 2D Mode and either Quality Color or Uniform Color from the Track Path Style drop-down list.
To change the Track Path length, select Edit > Preferences, click the Display tab, and in the Track Path Length text field, enter a number. MatchMover defines the maximum number of frames in which the Track Path is shown from the current time. A value of 100 shows the Track Path for 50 frames before and 50 frames after the current frame.
- 3D Tracks, showing the color-coded 3D reconstructed points (green for good, yellow for fair, red for bad), and a link to its corresponding 2D track, calculated after running the automatic tracking process. Hard tracks are displayed with a surrounding circle to easily identify them.
- Tracker Tool, showing the key search size and pattern size.

NoteTo change the color of the 2D View background, select Edit > Preferences, click the Color tab in the User Preferences window, and change the color of the corresponding sample box.

Displaying the 2D View attributes

You can display or hide points’ attributes by either:

Selecting Display from the main menu then clicking on the attribute in the pop-up menu.
Right-clicking in the 2D View and selecting Display and an attribute from the pop-up menu.

For the Masks and Anamorphism options, a check mark beside the option indicates that the option is active. Clicking the option again hides the check mark and deactivates it.

For other attributes, a single diamond shown beside the attribute in the menu defines that the attribute is displayed for the selected point.

If you click again, two diamonds appear beside the attribute defining that the selected attribute is displayed for all points. No diamonds means this feature is not displayed. By default the Point Label, Track Path, Tracker Tool, and Tracking Score are only displayed for the selected key point or computed point.

NoteTo change the color of the Track Path (in uniform color mode) or the key points on the track, select Edit > Preferences, click the Color tab in the User Preferences window, and change the color of the corresponding sample box.

Changing the time in the 2D View

The 2D View shows an image at a given time. The current time is shown in the top left corner of the viewport.

To change the current time, press Ctrl+click and drag the pointer. The pointer changes to .
To move to the previous frame, press Ctrl+left arrow.
To move to the next frame, press Ctrl+right arrow.
To reset the current time to the beginning of the sequence, right-click the required sequence in the Image Sequences folder in the Project window and select Goto Begin from the pop-up menu.

To hide the current time, select Edit > Preferences > Display and click in the Show Current Time in Viewports check box to disable the option.

Tip

If nothing is currently selected, just pressing arrows navigate through time/zoom.

Freezing the time

By default, time changes in the Time Line or other 2D views are always synchronized with current time. However, when you "freeze" the 2D View, changing the time in other views (the Time Line, the Track window or other 2D Views) does not affect the time in the frozen view. Other views are not synchronized with current time.

If you change the time in the frozen view, other views are synchronized with the current time in the frozen view.

The Freeze Time mode is useful if you need to study frames at different times, for example, when you have multiple 2D views and need to see them at a certain time, for instance when editing tracks in a helper frame.

The shortcuts Ctrl+left arrow or right arrow change the time in the frozen window only if the window is active (blue surround).

To freeze the time in the 2D View, do one of the following:

Select View > Freeze Time.
click the icon in the Workspace.
Right-click in the 2D View to show the pop-up menu and select Freeze Time.

Resetting the current view

To reset the current view, select Window > New View > New 2D View or press Ctrl+2 (default shortcut).

Navigating in the 2D View

You can access the navigation options in the View menu. Alternatively, use the following shortcuts and drag the pointer in the 2D View, Track View, Graph Editor, and Track Status View

Action	Shortcut	Pointer
Changes the current time	Ctrl+click
Move to next frame	Ctrl+right arrow	-
Move to previous frame	Ctrl+left arrow	-
Pan#	Alt+click (or scroll bars)
Zoom	Alt+Ctrl+click (or "+" or "-")
Zoom in an area in the 2D View	Alt+Shift+click

#Pan horizontally only in the Track View, Graph Editor, and Track Status View

In the 2D View:

click the Panicon in the Navigation toolbar at the bottom of the window and drag the pointer to perform the navigation.
Use the scroll buttons and slider to scroll through the images.
Click and hold the Navigate button to easily pan in the image. A popup window of the entire image appears with a rectangular guide to orientate you in the image.

In addition to the navigation options shown in the previous table, you can right-click in the 2D View and select the following options from the pop-up menu.

To center the view on the selected item, select View > Fit to Selection.
To set the largest zoom that keeps the entire image contained in the viewport select View > Fit to Viewport.
NoteYou can also click the Fit to Viewport in the Toolbar.icon.
If you have zoomed the image you can return to the original size with View > Reset zoom.
