Does 7D really have custom shutter speeds ?

It's not possible to shoot at a shutter speed that's slower than your frame rate. If you want to shoot at 1/10th of a second, the fastest your framerate could be is 10 fps. I guess the next best option would be in picture mode and shoot at 8fps.

Set the camera to video recording mode, and turn the Mode Dial to “M”. Now set any aperture that’s possible with your lens, any shutter speed from 1/4000th down to 1/30th or 1/60th (depending on frame rate — more in a moment), and any ISO you like from 100 through 6400.
The case for 24 fps: You’ll hear some experienced video shooters say that 24 fps generates more of a “film look”, meaning that certain types of motion appear more natural to your eye and brain. However, this slower frame rate can sometimes produce movements that are less smooth than when captured at 30 or 60 fps. This can be an issue if you anticipate frequent subject movement, or camera movement (think of “reality” TV shows as one example of this type of shooting where there is constant movement of both subject and camera). This also presupposes slower shutter speeds, around 1/50th of a second.
WHERE IS 1/50 ?

Yes, it's possible to record 24 fps at a 1/12 of a second, but that really ends up being 12 fps with duplicate frames in a 24fps. It still doesn't change the fact that it's 12 fps.

Yes but I believe that is accomplished by basically combining several frames into one. It's physically impossible to have the sensor exposed for separate frames 24 times per second, while each exposure lasts 1/10 of a second.
I'd love to know how you got to a 1/45 in the first place. I've never seen it on this camera.

Those thinking that "Setting shutter speed between 30 to 4K" means everything from 1/31, 1/32, to 1/3998, 1/3999 or something need to realize shutter speed and f/stop correlation. Every time you move a stop brighter the shutter speed correlates and moves a stop down as well. There's no real in-betweeners on a set scale.

That was me. My second GH1 film, "A Kindling Light". You find it on Vimeo through my sig link below.
Wrong. It was filmed at 1/2 second shutter speed.
I do know but I don't want to high-jack this thread so you can check info about how I did it and ask more here:

I had my CF1 : Exposure setting to 1/2 stop increments. So it moves 30, 45, 60 etc.
I changed it to 1/3 stop increments and now I get 30, 40, 50 etc.

If I understood your question correctly,
you're asking why you can not dial any number for the shutter speed, ex.: 1/30, 1/29, 1/28,..
Shutter speeds increase or decrease by FRACTIONS, values such as 1/7 or 1/22 do not exist in any camera.
it's like f-numbers, there are f2, f2.8, f3.2, but no such thing as f2.1 or f3.0 ...
