+          This demo video consists of images generated at one-minute intervals from the KMA GK2A satellite's full-disk images, originally captured at ten-minute intervals, using the VFI technique. By using the wipe scrollbar, you can compare the original video (delineated by a blue line) with the enhanced version. You can adjust the zoom and playback speed, and when played at 0.3x speed, the differences between the two videos become distinctly apparent.
