Even without image stabilization, in camera rolling shutter effects can be
pretty bad in high vibration settings. Your typical CMOS consumer sensor
scans one horizontal line at a time top to bottom and sacrifices scan speed
for image quality. Any motion between line scans causes the characteristic
"jello" effect on footage. You can repair a lot of rolling shutter
artifacts in post processing but high vibration test stand environments are
tough for that. I'm not sure how good those algorithms have gotten. They
might be pretty good on a static camera using fixed lines for alignment.
I've been thinking about finding some CCD cameras that don't use a rolling
shutter for engineering cams. The image quality will be worse generally
than CMOS but there are decent options for not too expensive. A quick look
on Amazon shows some decent digital microscope C mount CCD cameras for
under $100.
On the other end of the spectrum I have been looking at FPV cams for
stand/pad/vehicle using the analog wireless hardware. They're cheap, small,
and have potentially great range. I wouldn't use them for Ops critical pad
cams but otherwise they could be a great option. No sd card vibration
issues and getting live video all the way back to a bunker like at FAR
otherwise takes long cable runs.

Okay, I'll make sure to do that. I'm thinking of going with something
really cheap and small to put on the stand, something in the webcam
territory that can stream directly to a computer and then a DSLR from
much farther away for static fires.
How does vibration coupling or not
( camera fixed to stand or decoupled )
effect video quality?
