Halloween – Unidentified Flying Creature

Halloween may come and go, but we are forever fascinated with ghost and monster.

The other day I watched MonsterQuest of History channel on Astro about an unidentified flying creature, they call it Rods with multiple sets of wings. Some think it is a military weapon, others believe it may be a type of atmospheric beast from another dimension.



According to the cryptozoology, Rods are mysterious, elongated flying creatures. Some say it travels too fast to be seen with naked eye. However for decades cameras around the world have been capturing images of this flying, torpedo-like creature. But just what is it?



At the end of the show MonsterQuest sort of arrived at the conclusion that Rods are tricks of light, motion blur, artifacts of video photography. Interlacing is the likely culprit of the creation of this beast on all video footages.

Interlaced scan refers to a methods for "painting" a video image on an electronic display screen . Each frame of interlaced video is composed of two fields that are captured at different moments in time, interlaced video frames will exhibit motion artifacts if the recorded objects are moving fast enough to be in different positions when each individual field is captured especially if the camera is shooting at night with relatively long exposure times. The fast passage before the camera of an insect or even bird flapping its wings has been shown directly to produce rod-like effects.


Look closely to all the recorded footages in your DVR especially those recorded at Halloween night. You might had captured monster or ghost images on hard disk!
