Mysterious Rods
July 20th 2008 07:49
Rods ,what are they? Rods or sometimes referred to as flying fish are flying linear anomalies caught on video. These "rods" are not been seen at the time of taping.
They generally have appendages along their sides. Their overall appearance is of an elongated liner rod with horizontal transparent branches. Sometimes these 'branches' may have curved that are curtain like in appearance. These objects move at high speed and can not be seen with the naked eye. It can be difficult to capture rods on film even at 30 frames per second (fps), good video cameras still have problems capturing detailed pictures of rods. with rods moving up to speeds of 300 kmh.
There are documented cases of people switching video cameras on and letting them run only to find a streak pass by the camera when the tape is played back. They reported watching a frame by frame, motion of an object only to realise that the objects were not insects or birds... but something else.
There remains a high probability that the anomalies are caused by the equipment used in photographing these objects, some video and photographic cameras especially digital equipment can produce artifacts.
Some researches have indicated that rods are biological entities, if this true there should some evidence of dead rod material, to date no one has, found a body of a dead rod.
Understanding the difference between linear velocity and angular velocity is the key in why fast objects are seen to elongate at speed when photographed.
An artifact, that is very common as to be virtually ignored, is the fact that a fast-moving object will appear elongated on a photograph; those with very high angular velocities will appear as streaks. When a blurred streak appears on a photograph most of us will see it as a fast moving object.
Most of the footage I have seen is shot on video where the exposure times are slow compared to still cameras.
I have yet to see a “rod” shot on a regular still camera!!. The reason for the difference in images produced by a still camera with say s shutter speed of 1/1000 of a second can “freeze” a fast moving object. A slower shutter speed will tend to elongate the same image and distort it’s size and shape, making it appear longer and blurred.
Image of plane shot with 2 identical cameras both hand held ISO speed 100 one image shot at 1/60 of a second the other shot at 1/25 The slower shutter speed motion blur is emphasized. (see Image below)
Another common artifacts are lens flares. These are bright spots superimposed on the image by reflections of a bright objects seen as halos or rings are produced by imperfections in surfaces of a compound lens. When seen by most people the common mistake is that they think they are UFOs or "rods".

Can you HACK it?

Or am I thinking of something else?

No nothing to do with the sound barrier.
Just showing the difference exposure times (shutter speed on the camera) of the images can distort a shape and make it appear longer.
The plane image is an example I had on file.
The image could be of a car or person the same effect would be evident that shutter speed of the camera can distort images.

Not evertheng we see is what it apeears to be.
