Cessna takeoff and instrument panel in High Definition Video Casio
FC-100 is my new camera with high speed capability (up to 1000 frames
per second)

Video above is departing KMBO heading to Gulfport.

I am not happy with the way the prop displays in the video so my Kodak
Easy Share will still be my primary camera looking out the front..

instrument panel of the Cessna 172. Clarity of the gauges on the
panel looks good!

Down side to HD are the videos files are huge! Almost 200 megs a
minute!

Looks normal to me. What the prop does is a function of your shutter
speed.

Actually Roger, videos don't have "shutter speed" like still
photography. Both cameras record at 30 frames per second and you
can't control exposure time like a still camera (or a camcorder???).

The technical answer I received from rec.video.desktop as to why one
displays the prop different from the other is the way the camera
records the data to the SD card. Newer cameras record "line by line"
causing the venetian blind effect. My older Kodak Easy Share camera
records frame by frame to the card causing the prop to be seen in it's
whole state.

Mine does. It's digital with an adjustable shutter speed from
something under the standard 30 at fps to something on the order of
1/1000ths

They are only partially right. Like the old saying, some do and some
don't. The Venetian blind effect should be recording by "every other
line".

The cameras don't record to the SD card, but rather write to the card
after the image is taken. Some may write to it directly, but that'd
be the cheap way without buffering.

Technically the cameral should record to a buffer and there is no
reason except cost savings (cheap) for recording line by line, or
every other line.,
