Is it possible?? Hvx exposure

OK, I have a question. I do the hvx hack( shooting at 2 fps and I get great natural lighting when shooting at night( city shots)

why cant we open the iris all the way up like that and still shoot at 24 fps??? I even put the s. scan to 350.00 but it doesn't look the same as it does shooting at 2 fps.

is there a way to do it?

thanks a lot
 
It's all about the shutter speed. You cannot have a shutter speed that's slower than your frame rate. So at 2fps, you get one frame every 1/2 second, and at 350.0d you're getting a shutter speed of about 1/2 second. Therefore you get fantastic light performance and great light streaks.

But at 24fps, the very most-open shutter you could ever have is 1/24. If you go to any slower shutter (like 1/12) it'll affect your frame rate; 1/12 exposure dictates 12fps frame rate.
 
Actually, if you are desperate to get clean nightime footage and do not mind the strobe, shoot with the hack in a non PN mode like 720 24p or 1080 24p. This will allow you to lower the shutter speed allowing lots of light (and motion blur) but not have to deal with adding duplicate frames in post. It has saved me on a few locked off night shots (but there has to be little to no movement to pull off the effect cleanly).

thanks for the info barry
 
Does that mean that on the DVX, when u shoot at 24pA with the slow shutter (1/6), you're actually changing the frame rate to 6 fps?
 
Yes and no. Yes, you'll only see six distinct frames per second. But it's still recording 24, so each of those six frames will be duplicated and therefore recorded four times each.
