HPX250: Adjustable shutter?

Shooting AVC-Intra 24p, somewhat low (natural) light situation, not much subject movement. I can not add my own light sources.

I usually shoot with the shutter set at 180 degrees which in this case would mean 1/48 sec shutter because of the 24p framerate.
What if I wanted to slow my shutter down to allow more light in?
It seems like my only choice is either 1/6 or 1/12? I think this would be a little too slow causing excessive motion blur.

I'm trying to let more light in so I can have the aperture of the lens in a more optimal setting.
I'm hoping this will improve my picture quality.

Can't I set my shutter to 1/24 or even 1/30?
Am I missing something?
 
Ok, I figured it out. I need to be in the syncro scan settings mode which will then allow me to dial in the shutter speed.
In shutter settings mode you are limited to only 2 lower shutter speed settings. (in relation to your frame rate)

Now, can anyone weigh in on whether or not this approach will provide better picture quality?
Having my frame rate at 24p shutter at 1/24?

By better picture quality I mean, less noise, sharper overall image.

This will let me leave the gain off and also allow me to close my aperture down a bit.
I do realize that I will get more motion blur but in this particular case my subjects are standing relatively still most of the time.
 
My thought is I tested this a bit one day. I noticed that if the camera was happy with the amount of light then the shot was nice. If it was still too low, it didn't look too great, plus the blur. However the blur mostly happened only when I moved the camera. If I left it alone the motion blur didn't seem very bad. I would gain up and run PAP1 first and a good scene file to help with light. Then I would drop my shutter if all that didn't make any difference.
 
I just shot a venue that previously gave me trouble with image quality (lack of sharpness and noise). I shot it at AVC-Intra 100- 1080/24p.
This time I set my shutter speed to 1/30 instead of at 1/48.
I did not use any gain and the slower shutter speed allowed me to keep the aperture at around 4.2
I did have the camera in the Pap1 setting as well.
Well, I have to say that the results were much improved over what I had previously gotten. Although it was a little underexposed I was able to push it a bit in
software and get acceptable results.

Maybe next time I will try 1/24 to see if that improves the picture any more.
Feeling a little better about my HPX-250.
 
Open up the aperture a little. You'll get better image quality and a brighter image if you go to F3.5.
