SAM3_TrackPreview - ComfyUI Built-in Node Documentation

Overview

This node creates a video preview of tracked objects, drawing each tracked object with a distinct color overlay and a number label. It does not output any image or video tensors — instead, it saves the resulting preview video directly to a temporary file.
