View & Display¶
Everything here lives under the View menu, and most of it is also in the View panel.
Zoom and pan¶
| Action | Shortcut |
|---|---|
| Fit view to instances | Cmd+= / Ctrl+= |
| Fit view to selection | View ▸ Fit View to Selection |
| Reset view | R |
| Toggle pan mode | P |
With the mouse and trackpad:
| Gesture | Does |
|---|---|
| Scroll (wheel or two-finger) | Pan |
| Ctrl + scroll | Zoom toward the pointer (Ctrl on macOS too) |
| Trackpad pinch | Zoom, in Chrome and Edge |
| Middle-button drag | Pan |
| Hold Space and drag | Pan |
| Drag on empty canvas | Draw a selection box |
Default to Pan Mode (P) makes a plain drag pan instead of drawing a selection box — handy when you're reviewing rather than editing. You can still drag nodes in pan mode. In pan mode, Space-drag selects instead, Cmd / Ctrl-drag zooms, and double-clicking empty canvas resets the view.
Two aids for precision work:
- Crosshair When Zoomed — draws crosshairs so you can line a point up exactly
- Magnifier When Moving Nodes — a zoomed view in the top-right corner of the video while you drag a node, while you place nodes, or while you hold Shift. The magnifier button on the video turns it on and off too, and the View panel sets its size and zoom.
- Play Neighboring Frames in Magnifier — while the magnifier is up from holding Shift or placing nodes (not while dragging), it loops through the frames around the current one, so you see the motion around the point you're labeling. In the View panel, choose earlier and/or later frames and how many on each side (1–10, default 2).
What gets drawn¶
| Toggle | Shortcut |
|---|---|
| Show instances | H |
| Show node names | T |
| Show edges | Cmd+Shift+Tab |
| Show non-visible nodes | Shift+V |
View ▸ Display sets a coarser policy for showing occluded geometry:
| Mode | Shows |
|---|---|
| Manual | Whatever you toggled by hand |
| Only selected (with hidden points) | Just the selected instance, hidden points included |
| All instances, visible points only | Every instance, visible points only |
| All visible + selected hidden points | Everything, plus the selected instance's hidden points |
Color¶
View ▸ Apply Distinct Colors To decides what the palette is spent on:
| Mode | Distinct colors per |
|---|---|
| Auto (Node / Track) | Nodes when there are no tracks, tracks when there are |
| Tracks | Identity — the right choice for reviewing tracking |
| Instances | Instance — useful on frames with several untracked animals |
| Nodes | Body part — useful for checking a skeleton |
| Edges | Connection |
View ▸ Color Palette picks the palette: standard, five+ (more distinct hues, for many tracks), or alphabet.
View ▸ Color Predicted Instances controls whether predictions get the same color treatment as user labels, or are drawn distinctly so you can tell at a glance what still needs accepting.
Sizing¶
- Node Marker Size — how big the node circles are
- Pose Opacity — 100%, 75%, 50% or 25%, to see the animal under the pose
- Node Label Size — how big node name text is
- Edge Style — Line or Wedge (wedges make direction along a chain readable)
- Trail Length — how many frames of motion history to draw behind each instance
- Text Size — the whole UI's text scale (Cmd+Shift+= / Cmd+-, and Reset to Default)
Layout¶
- Side Panel — show or hide the panel column
- Sidebar on Left — move it to the other side
- Allow Multiple Panels — open several panels at once instead of one at a time
- Panels ▸ Reset to Defaults… — put the layout back
The Panels menu opens any individual panel; see the panels reference.
