Have seen the KC135 before but never the others - some nice aircraft videos.
Nice passtime is to watch a/c vids on youtube. :-)
(Which was what I was doing when you post appeared on aus.aviation)
Thanks for that.

I'm intrigued by the illusion of the engines running backward - perhaps some
of the photographers in this group can explain what causes this effect.

Regarding the Martin(?) Mars- are there any still flying? - it seems to be
bigger than a Short Sunderland.

Interaction between frame rate of the camera and rotation speed of the
prop. Reminiscent of way we used to set the timing on an auto engine
with a strobe light.

Intervals are usually around 30 frames sec. for normal motion: not to
be confused with shutter speeds, which for still or motion can be from
1/60th sec. on up for handheld cameras, depending on the speed (light
sensitivity) of the film.

More than you wanted to know. Theses days we just point and shoot.

Actually, it is do do with shutter speeds. Modern video cameras have
electronic shutters. They are used to avoid the blurring effect often
associated with video cameras and slow motion effects. If the shutter speed
wasn't set high the propellor blades would be seen as a blur. I prefer to
set the shutter slower for these types of shots.

Here's a better explanation

There were only original only four used for fire fighting. Now there are
only 2: Hawaii Mars and Phillipine Mars.
They are both up for sale.
