This link right here should hopefully solve your problems.

Perhaps the contact taping method suggested here might help you:

Have you tried widening your aperture to maximum and taking a really close-up shot?
This will not fix your flicker at all, but this will give it maximum bokeh, and if the problem is in fact fluctuating aperture, then you will see the size of the bokeh change with the flicker and you will then know if the problem is that.  And if this is the problem then I do have a fix.
There isn't much depth to the shot shown, so I can't really tell if that's the problem.

Oh, I've tried the tape thing, it doesn't work at all.

First, take off the lens off of the camera body and take off the lens cap.
Look through the lens and you will be able to kinda see through it, not well, though, but you'll be able to see the size of the aperture, which, by default, will be closed as tightly as it can get.
Around the part of the lens which connects to the body, there is this switch which controls the size of the aperture, if you move this around, you should be able to see the that you are changing it.
However, if you let go, it will snap back into a very small position, which you don't really want.
So what you need to do is jam tiny bits of paper around the switches to try to set it at the aperture you want.
Of course, getting it just right will take a while, also, changing it again will become very annoying, but it should be quite a lot better.
After trying this, Leprechauns in France became almost entire flicker-free besides a few shots which are still mysteriously flickery.  I haven't a clue as to why.  But it's obviously much better than Sharks and Clowns or my THAC films.

The flicker on this looks weird. I was going to suggest it might be an automatic aperture issue as others are pointing to until I watched it. You should still try what Squid said, if you haven't already, as it's possible that's the issue. That said, I think that generally darkens the whole image, whereas your clip looks like only certain reflections are brighter (though you seem to have taken precautions to avoid animator reflections). The other thing that could cause that is one of several light sources flickering brighter.

Vacuum cleaners and clothes dryers in somewhat close proximity can cause certain lights to flicker a little bit. I'm really not sure, otherwise.

Grumble. Squid, that method doesn't work on my lens, because they don't have a manual aperture ring. Either that, or you just have some different lens than mine. I don't know.

Stopping down too low, or using fast shutter-speeds can also cause light flicker, or so I read.

EDIT: Jackpot! Scroll down to 'the lens' and read a bit: http://blogs.adobe.com/aftereffects/201 … raphy.html

Edit/Conclusion: The method mentioned above works on my camera (EOS 30D with a .... lens), but it seems that it is possible that the source of my light flicker is 'fluctuating electricity'. I really don't know what to do about that, but most people say longer exposures should balance the frames. I hope that's true.
