is 30p better than 60p in low light

I need this answer right away, I hope it's not a dumb question, but would shooting 720 at 30p work better in low light than 720 at 60p?
I'm shooting in a dark church tomorrow, and I have not been as happy with the low light of this camera verses my old Sony DSR300.
Don't get me wrong I'm glad I upgraded, but alot of the shots that look fine in the view finder, look alot darker on the computer.

any suggestions? or comments?

Thank you.

30P will be the same as 60P, assuming the same shutter speed.

If you choose to open up the shutter to 1/30, then yes you can have a full stop brighter picture in 30p as compared to 60p, but recognize that the motion blur will be quite different too.
 
Thank you for your answers. If I'm reading them right they contradict one another.

I know that if you change the shutter speed from 60 to 30 it allows more light to reach the chips.

If you change the format from 60P to 30P, does it have any effect on light sensitivity?

Thanks for the input.

No, changing the 60p to 30p setting has no effect on sensitivity. The only way you'd gain any low light performance by going to 30p, would be because you could then use a slower shutter speed.
 
in practice, though, when you change the framerate on the HPX it automatically switches the shutter speed as well, unless you have the electronic shutter turned on. So if you change from 60p to 30p, the image does become a stop brighter.
 
Only if you're in the syncro-scan mode with the shutter set in degrees. If you're using a set shutter speed then there's no relative shutter change based on frame rate.

However, the shutter speed doesn't stay exactly the same when switching recording modes; it might go from 1/60 to 1/100. So you have to watch it to see what you've set it at.
 
I think we're saying the same thing, but synchro scan isn't necessary, nor is setting the shutter in degrees. As long as you have the custom shutter turned off (shutter switch under the lens set to Off), changing the record mode from 60p to 30p will instantly make the image a stop brighter, and 24p gets the extra 3rd of a stop or so. Effectively, the camera defaults to a 360° shutter.

If you manually set a shutter speed, as you said, changing the framerate won't affect that, so the exposure won't change.
