Rod (optical phenomenon)

Rods, a rather new entry in the field of cryptozoology, are said to be creatures which flit about in the air at such a high speed as to not be seen by the naked eye. Rods appear to be observational artifacts produced by rapidly flying animals. Practically all sightings of rods are based on video evidence, due to the propensity of video cameras to produce characteristic stroboscopic artifacts when imaging rapidly flying animals, especially insects, but also including birds. Their recent popularity seems to be a result of media exposure in television and in tabloids. Jose Escamilla has appeared in numerous interviews and television "investigations".

Rods gain their name from their rodlike shape. However, they have also been called "flying rods", "skyfish" and "solar entities". They appear to be anywhere from 12 cm to 50 metres in length, and it is proposed that they have a thin membrane across their axis which is used for propulsion through the air, in a manner similar to the way a cuttlefish uses its fins. It has been suggested that Rods are possible relatives of anomalocarids which have taken to the air. Rods can control their flight path as birds and insects do. Rods are not classified as atmospheric beasts because rods are nearly always described as much smaller than atmospheric beasts, as invisible to the naked eye; in addition, rods have a much shorter history as a subject of research in cryptozoology and the paranormal.

Explanations

Evidence points to the conclusion that they are mere tricks of light which result from how images (primarily video images) are recorded and played back. In particular, the fast passage before the camera of an insect flapping its wings has been shown directly to produce rod-like effects, due to motion blur, if the camera is shooting with relatively long exposure times. ([1]) (In low-light conditions or even when pointed at blue sky, the automatic exposure programming of a video camera is likely to select the longest possible exposure time, which is 1/60th second per video field for NTSC format or 1/50th second for PAL format.) This criticism points to such video being physically unable to capture a clean image of something which moves so fast relative to the camera. In particular, the "membrane" in a video frame of a rod is effectively a time-lapse of the wings of the flying animal in different positions over several wingbeats that occurred during the field exposure time, while the central "rod" is a time-lapse image of the body, showing the full distance traveled during the field exposure time. The effect is especially pronounced with large, long-bodied insects which have broad wings and fairly slow wingbeats, such as mantises, grasshoppers, and katydids, or completely opaque wings such as moths. On video equipment which resolves the two interlaced fields of a single video frame (which are captured successively and then displayed as alternating horizontal lines), the "rod" effect can be seen to alternate from one field to the other, producing the distinctive gaps between successive images ([2]). Similar results can be produced using standard film, if there is a long exposure and/or a stroboscopic lighting effect which lasts more than a single wingbeat. This is the technical evidence, demonstrating that one can produce "rod" effects at will if one uses the right equipment, lighting, and subject.

Also Understand that Video Cameras record film at predictable rates. Typical Film Rates are 24.9 Frames Per Second, 29.95 Frames per second, and many others. So If you are filming at lets say, 30 Frames per second and an Insect flaps its wings at 120 Flaps per second, then if you film the bug Every SINGLE Frame of video will have that bug flapping its wings 4 times. FOUR times on every frame. If they flapped 4 times per frame, then it also will have its body moving the equal distance of 4 flaps in a linear direction on each frame. A distance of 4 flaps directly in front of a Camera Aperture (Lens) would make the insect look long, straight, blurry and the wings would be in the shape of a wave like motion. Pay attention to the videos of "Rods" and notice that in the videos the rods NEVER move the "wing" once the image shows up. Thats because it is an over exposed animal. Some Insects can flap their wings at 300 flaps per second and even faster. That would look insane on a camera filming at 29.95 frames per second.

On an interlaced camera, these effects are doubled, as pointed out on the "Monster-Quest" show aired on the History Channel in Jan 2008.

"I would also like to point out that there was not a single piece of video on that show, that I could not explain using Science, Math and Physics"(This is a statement and can be viewed as fact, opinion, theory or falsehood by the reader).

Capturing Rods

On 8th and 9th August 2005, China Central Television (CCTV) aired a two-part documentary about flying rods in China. It reported an incident which happened from May to June of the same year at Tonghua Zhenguo Pharmaceutical Company in Tonghua City, Jilin Province, which debunked the flying rods. ([3]) Surveillance cameras in the facility's compound captured video footage of flying rods identical to those shown in Jose Escamilla's video. Getting no satisfactory answer to the phenomenon, the curious research staff of the facility, being scientists, decided that they would try to solve the mystery by attempting to catch these airborne creatures. Huge nets were set up and the same surveillance cameras then captured images of rods flying into the trap. When the nets were inspected, the "rods" were no more than regular moths and other ordinary flying insects. Subsequent investigations proved that the appearance of flying rods on video was an optical illusion created by the slower recording speed of the camera (done to save video space). This is the empirical evidence, showing that the "rods" themselves can be captured, and that they do indeed prove to be ordinary animals.

Rods in popular culture

Rods were a subject of intense debate in the 14th episode of filmmaker Kevin Smith's SModcast, released June 13, 2007. Smith discusses with his co-hosts Walt Flanagan and Malcolm Ingram the known details of the "Rod Phenomena", and Flanagan's claimed sightings near Henry Hudson High School in Highlands, New Jersey, and during a New Jersey Devils ice hockey broadcast.
Rods were the subject of season 1, episode 11 of The History Channel's series, Monster Quest. Near the end of the episode, a "rod" is captured simultaneously by a traditional video camera and a high-speed camera. While the video recorded by the traditional camera showed a brightly-illuminated "rod" with multiple undulating wings, the high-speed video clearly showed a common moth flying across its field of view.
Numerous games or animated features include creatures that appear to be modeled on "rods" and their purported properties, including Castlevania: Aria of Sorrow, La-Mulana, Zettai Shounen, Eureka Seven, d20 Modern, Jojo's Bizarre Adventure, and Shadow Hearts: From the New World.
