Hi Goff,
Apologies for the delay in responding - your email was lost in the pile of
Europa related stuff that was in my mailbox.
I have been trying (off and on) to get good in cockpit quality for the last
5 years.
It seems that as soon as you mount a camera to the aircraft structure this
picks up the vibrations on the airframe. I have used a Sanyo video cam, a
VIO POV camera and latterly my Canon EOS 650.
Both the Sanyo and the Canon have Image stabilisers and are very effective
in reducing the camera shake - the problem is they both have relatively
narrow lens angles (so you can't get the whole cockpit in frame). I did buy
a wide angle adapter for the Sanyo but it isn't that wide angle and degrades
the image quality. In all other respects it makes a decent job of in cockpit
video.
The VIO (http://vio-pov.com/) has a similar really wide angle to the GoPro
and the quality is superb but as soon as you attach the lens to anywhere in
the cockpit you get bad camera shake. If mounted on my headset (side of ear
cup) the shake goes away but as a pilots head scans the horizon frequently
its very difficult footage to watch - also the camera is too far forward and
you lose the cockpit panorama. The strange image you get with the rotating
prop is a bit annoying but nothing I cant live with. I think VIO have since
brought out a software fix for this anyway. If not I will definitely look at
mounting a piece of ND filter in front of the lens.
I have looked at various ways of isolating the vibrations but as yet nothing
worked. It seems that the built in stabiliser systems are the only way
forward. I believe the latest GoPro cameras have this built in (it may just
be in the processing software).
Unfortunately I am (or rather was) a professional photographer and tend to
be a little more picky than most - so my fault. Now that I am retired I
should have more time to look at the problem - im sure there is a simple way
of tackling the problem.
Again, congratulations on the video footage at Bembridge - I realised that
your original footage would have been better quality but was just curious to
see how much better the original was.
Thanks for getting back to me.
Kind regards,
Carl

Carl,
Yes I do have the HD original. It's even better than the YouTube posting,
which degrades the original a bit.
Bob,
I'm not sure what you mean by image shake. Do you mean vibration from the
prop and the fuselage? The GroPro is mounted to the cabin roof, just aft of
the seats. I don't think it has built in image stabilising software, so it
must be my smooth flying!!
If you mean the absence of prop strobing, that's down to a little neutral
density filter popped inside the GoPro case in front of the lens. I cut a
piece the size and shape of a one euro coin from a sheet of theatrical
lighting filter acetate. Works wonders.
