Summary: A tutorial showing how to identify and mark star clusters in a cosmic image using interactive highlighting tools.

The video displays a vibrant field of stars, featuring both blue and orange celestial bodies. It guides the viewer through the process of identifying distinct star clusters. Initially, a large blue cluster in the upper-left is highlighted with a blue circle and a target icon. The highlight then shifts to a smaller cluster in the lower-right, followed by another cluster in the mid-right. Each cluster is temporarily marked with a blue circle that expands slightly and an initial target icon, simulating an interactive selection process.

1. startTime: 00:00 endTime: 00:01 label: A dense field of blue and orange stars is shown. A blue circle and target icon appear, highlighting a star cluster in the upper-left. 2. startTime: 00:01 endTime: 00:02 label: The blue circle around the upper-left cluster expands slightly, and the target icon disappears. 3. startTime: 00:02 endTime: 00:03 label: The upper-left circle disappears. A new blue circle and target icon appear, highlighting a different star cluster in the lower-right. 4. startTime: 00:03 endTime: 00:04 label: The blue circle around the lower-right cluster expands slightly, and the target icon disappears. 5. startTime: 00:04 endTime: 00:05 label: A third blue circle and target icon appear, highlighting another star cluster in the mid-right, while the lower-right cluster remains highlighted. 6. startTime: 00:05 endTime: 00:06 label: The target icon within the mid-right cluster disappears, and its blue circle expands. The lower-right cluster highlight is still visible. 7. startTime: 00:06 endTime: 00:07 label: The lower-right cluster highlight disappears. The mid-right cluster highlight is visible, and a crosshair cursor appears in the upper-right. 8. startTime: 00:07 endTime: 00:08 label: The mid-right cluster highlight disappears, leaving only the star field and the crosshair cursor. 9. startTime: 00:08 endTime: 00:10 label: The star field and crosshair cursor remain visible until the end of the video.
