This is a test for the Jello Effect in my Casio Ex FH100 high speed video camera. Camera settings: Manual, 240fps, 1/10,000s, ISO 3200?
To advance or go back a single frame HOLD SHIFT KEY & USE RIGHT & LEFT ARROW KEYS.
The object was a straight bar made by putting retro- reflective tape (3M 03456C) across the diameter (31 mm) of a disc. The bar extends across about 64% of the height of the frame. To darken the disc black plastic tape was put on the rest of the disc. The disc was mounted in a Dremel tool and rotated at a nominal rate of 20,000 RPM or 330 RPS. With frame rate of 240fps the disc rotated more than 1 revolution between frames. A very intense flashlight next to the camera was used for illumination of the retro-reflective tape.
Under these conditions the image of the straight bar appeared to split into two or three separate & very curved parts. The width of the bar was also widened considerably due to the 1/10,000s shutter speed.
This is an example of extreme distortion from Jello Effect. Motions this rapid should not normally be encountered, for example, in sports motions.

Hmm…it looks like things are taking a while to load. Try again?
