Clip Display
This pop-over contains various display settings for both Tracking mode and Mask mode.
R, G, B
Controls the color channels used for the frame preview. The tracking algorithm works with grayscale images, and with these options, you can check which combination of enabled and disabled channels will yield the best contrast and the least noise.
Note that this only affects the preview. To select which channels to use for the actual tracking, use the Track tab in the Toolbar to set a default for newly created markers, or the Track tab in the Sidebar to configure existing markers.
Grayscale Preview (B/W)
Shows the whole frame as a grayscale image.
Mute (eye icon) M
Hides the movie clip and displays a black image instead. This helps to find markers that are tracked inaccurately or not at all.
Render Undistorted
Applies the Lens settings to the video preview to undo lens distortion. Does not change the footage itself.
Show Stable
Applies the 2D stabilization settings to the video preview. Does not change the footage itself.
Grid
Displays a grid which is originally orthographic, but is distorted by the Lens settings. This can be used for manual calibration: the distorted grid lines should match lines in the footage that are meant to be straight.
Calibration
Applies the Lens settings to annotation strokes. Like the Grid, this option also helps to perform manual calibration.
Display Aspect Ratio
Changes the aspect ratio for displaying only. It does not affect the tracking or solving process.
Marker Display
Determines how markers are displayed in the editor.
Pattern
Whether to show the pattern areas of tracks. Can be used to reduce clutter and check how good tracking is.
Search Alt-S
Whether to show the search areas of selected tracks. Can be used to reduce clutter and check how good tracking is.
Path
Shows past (red) and future (blue) positions of tracks relative to the current frame, visualizing how they move. This makes it easier to spot irregularities.
Length
Length (in frames) of the Path.
Show Disabled Alt-D
When unchecked, hides the tracks that are disabled on the current frame (except for the active track, i.e. the one that was selected last). This helps to make the view more clear and see if the tracking is accurate enough.
Info
Displays the name and status of each selected track. The status can be “keyframed,” “tracked,” “disabled” and so on.
3D Markers
Shows the result of solving the markers’ 3D locations based on their 2D movement. Each 3D location is projected back to the movie clip and displayed as a small point, which is colored green if it’s close to the original 2D marker (meaning a good solve) or red if it’s far away (meaning it needs to be tweaked).
Display Thin
By default, marker areas are displayed as bright boxes with a black outline. This option displays them using thin dashed lines instead.
