  • Download Movie_S01 (MOV) - Traveling waves of the tectorial membrane revealed. The displacement from mean location of the membrane in the input video on the left was amplified 20 times to produce the motion magnified video shown on the right. The original video consists of eight frames. The included video repeats these eight frames 10 times for 80 frames and plays the result at 10 FPS.
  • Download Movie_S02 (MOV) - The input bridge video is concatenated with two motion-magnified videos revealing different modal shapes of the bridge. Motions within a 1.6- to 1.8-Hz frequency band are amplified 400 times to produce the video on the right, in which the first bending mode is revealed. Motions within a 2.4- to 2.7-Hz frequency band are amplified 250 times to produce the video on the bottom, in which the first torsional mode is revealed. The impact of the central span (not shown in the video) occurs ~5 s after the video’s start.
  • Download Movie_S03 (MOV) - The input pipe video concatenated with five motion magnified videos revealing different modal shapes of the pipe. The subvideos were scaled up using bicubic interpolation by a factor of 50%. The video was recorded at 24,096 FPS and played back at 30 FPS.
  • Download Movie_S04 (MOV) - A probe vibrates the metamaterial at 50 Hz. The input high-speed video is shown on the left. Motions within a 40- to 60-Hz frequency band are amplified 80 times to produce the video on the right, in which the propagation of the vibrations is revealed. The video was recorded at 500 FPS and is played back at 30 FPS.
  • Download Movie_S05 (MOV) - A probe vibrates the metamaterial at 100 Hz. The successful attenuation of vibrations are revealed in the motion magnified video on the right, in which motions in a frequency band of 90 Hz to 110 Hz are amplified 250 times. The high-speed input video of the metamaterial is shown on the left. It was recorded at 500 FPS and is played back at 30 FPS.
