“The phonotrope is a modern version of a zoetrope or phenakistoscope toy that you may have seen or played with,” artist Tess Martin explains in this behind-the-scenes video about how-to make a phonotrope.
“While you spin the disc and look at the animation directly, the animation appears blurry. However, when you look at the animation through the slits, the animation comes alive. This effect occurs because our eye needs a little break in between each image for us to register it.
“So, the phonotrope is essentially the same as these traditional devices, except the slits are replaced with the frame rate of the video camera that is filming the disc.”
Martin demonstrates the technology, the math, and her creation process, including how to synchronize between the frame rate, disk rotation speed, and the number of drawings on the disk to produce an animation, as well as how to create the discs on the computer using Photoshop and AfterEffects software.
Note: Her narration volume varies; closed captioning may be required for some sections of the tutorial.
“You can also film your phonotrope with a phone camera, not just a DSLR, as I did for an interactive installation project. However, it requires a bit more effort because you usually need to download a third-party app to your phone to control the framerate and shutter speed. Nonetheless, this method provides a great way to experience the phonotrope. You can even print your animation onto a playable record for added novelty.”
“The phenakistiscope (also known by the spellings phénakisticope or phenakistoscope) was the first widespread animation device that created a fluent illusion of motion. Dubbed Fantascope and Stroboscopische Scheiben (‘stroboscopic discs’) by its inventors, it has been known under many other names until the French product name Phénakisticope became common (with alternative spellings). The phenakistiscope is regarded as one of the first forms of moving media entertainment that paved the way for the future motion picture and film industry. Similar to a GIF animation, it can only show a short continuous loop.”
