Add a Magnetic Mask in Motion

In Motion, use the Magnetic Mask to easily isolate people, objects, and shapes from the background using machine learning. You can then apply the mask to the rest of a video clip automatically, without time-consuming manual tracking or rotoscoping.

Add a Magnetic Mask to isolate a subject from its background

Adding the Magnetic Mask effect to a clip creates a matte, which allows you to composite the isolated foreground image over a different background image.

In the Layers list or Timeline in Motion, select the clip you want to mask, then position the playhead at a point within the clip that shows the area you want to mask.
Do any of the following:
- In the canvas toolbar, click the Magnetic Mask tool.
- Choose Object > Add Magnetic Mask.
- Press Option-Shift-Command-M.
  The pointer changes to the Add eyedropper in the canvas (for adding parts of the image to the mask). As you move the eyedropper in the canvas, objects and shapes in the image are highlighted in a bright color.
In the canvas, position the eyedropper on an object or shape that you want to mask, then click to select it.
A mask and control point are added to the canvas. The control point defines the area to be masked. Additionally, a Magnetic Mask object appears beneath the clip in the Layers list and Timeline, and a reference/analysis indicator (a circled dot with a vertical line through it) appears in the Timeline at the affected frame. That reference frame is used to calculate the mask position in subsequent frames when you analyze the rest of the clip.
To add or subtract from the selected mask area, do any of the following:
- Add to the selection: Click an area in the canvas with the Add eyedropper . Each click with the Add eyedropper places a green control point in the canvas, adding an area to the mask.
- Subtract from the selection: In the Magnetic Mask Inspector, click the Remove button in the Selection Tools row, then click an area in the canvas with the Remove eyedropper . Each click with the Remove eyedropper places a red control point, removing an area from the mask.
  To switch back to the Add eyedropper, click the Add button in the Inspector.
  Tip: To switch between eyedroppers temporarily, press and hold the Option key, then click in the canvas. When you release the Option key, the tool reverts to the previously active eyedropper.
In most cases, you need only a handful of control points to select the object or shape you want to mask. There’s no measurable effect after about 20 control points.
To further refine a mask, see Edit a Magnetic Mask.
To extend the Magnetic Mask to additional frames of the clip, do one of the following:
- Apply the mask to the play range: Click Analyze.
  Note: If you added the Magnetic Mask to a frame before the play range, forward analysis stops at the In point of the play range; if you added the mask after the play range, backward analysis stops at the Out point of the play range.
- Apply the mask to the previous or next frame: Click the Previous Frame button or the Next Frame button .
  When you click or , an analysis frame (white vertical line) is added to the Timeline. That frame is used as the basis for the subsequent frames when the mask is calculated.
- Apply the mask to the portion of the clip before or after the current frame: Click the Analyze Backward button or the Analyze Forward button .
  To cancel the analysis, click Stop in the analysis progress window. You can also press Command-Period (.) or press the Esc (Escape) key.
The mask is extended to all analyzed frames. In the Timeline, the range of analyzed frames is represented by a light gray bar.
To view the Magnetic Mask result, click the Show Result button in the Magnetic Mask Inspector.
If you’re not satisfied with the result, make further refinements.
Optional: To mask additional elements in the clip, select the clip layer again and repeat steps 1–7.
If you add multiple Magnetic Masks to a clip, change the active mask by selecting a different mask in the Layers list or Timeline.

When you save the project, the Magnetic Mask analysis files and any clips or images used in the project are saved to a folder (in your chosen save location).

Modify mask viewing options

You can view the result of a Magnetic Mask, view its alpha channel, change its highlight color, or show or hide its selection outline.

In the Layers list or Timeline in Motion, select a Magnetic Mask.
In the Magnetic Mask Inspector, do any of the following:
- View the result of a mask: Click the Show Result button .
- View a mask’s alpha channel: Click the Show Result button , click the Channels pop-up menu (in the upper-right corner of the canvas), then choose Alpha.
  To show all color channels in the canvas, click the Channels pop-up menu (in the upper-right corner of the canvas), then choose Color.
- Change the highlight color for a mask: Click the Select Objects button , then click the color well and choose a new color in the Colors window.
- Show or hide a mask’s dashed selection outline: Click the Select Objects button , then select or deselect the Show Contour checkbox.
