Video Segmentation

The Segment Anything 2 modifier follows a subject through a video and makes a mask.

Create a mask

1. Select a visual clip and add the Segment Anything 2 modifier.

2. Move the playhead to a frame where the subject is clear.

3. Click the subject in the preview to add a foreground point. Right-click or Control-click to mark background that should be excluded.

4. Add more points as needed, or drag across the preview to draw a box around the subject.

5. Select Analyze and keep the compute server running until the mask is ready.

Adjust the result

Threshold moves the mask edge. Edge softness feathers it. Invert swaps inside and outside.

After you move a point, change the box, or pick another model, select Reanalyze.

The server can offer SAM 2.1 tiny, small, base-plus, and large.
