These changes between shots can clearly be seen in the motiongram (marked with Camera 1 and 2). First, the recording is composed of alternating shots from two different camera angles. There are two problems with this motiongram. I then moved on to create a motiongram of the video: Is it possible to see some of the same effects in the motion? Motiongrams The audio is sampled at a much higher frequency (44.1 kHz) than the video (25 fps). Here you can really see the change in both the frequency and the onset strength. However, a tempogram of the audio is even clearer: If you are used to looking at spectrograms, you can quite clearly see the change in frequency as the drummer is speeding up and then slowing down again. Audio visualizationīefore delving into the visualization of the video file, I made a spectrogram of the sound: I was therefore curious about the level of detail I could achieve in the further analysis. Obviously, the framerate of the video is not able to capture the speed that he plays with. Since the background is removed, only the motion is visible.
