I don't think I ever use my CMC for fish apart from static ones that are convinced they are invisible, or ones that are still in their eggs :)

Nice tests Richard. I love my CMC. My Subsees get left at home since I got mine.

The traditional standard for movies and video is a shutter speed of half the frame rate (known as 180 degree shutter because old rotary shutters were open half of a 360 degree rotation) i.e. 1/50 for 25fps. 1/60 for 30fps. This gives a natural smoothness to motion without being too staccato (from faster shutter speeds) or too blurry (from slower shutter speeds). But the shutter absolutely doesn't have to be set to that. If there is no motion in the video then it doesn't matter, and a 360 degree shutter (e.g. 1/25 at 25fps) can be useful in low light situations where your aperture is wide open and you don't want to increase ISO any more because of noise. Conversely, loads of the footage in my Mucky Secrets documentary was shot at shutter speeds faster than 1/50 because I had too much light and I was out of the habit of using ND filters. However if you're shooting 25fps video with 1/25 shutter speed and there is substantial movement then the result is going to be blurry and you're better off adjusting other parameters to get more light if you can.
