Trying to get the same settings for 25 and 50 frames. It looks like the brightness is turned down when going to 50 frames?

Any idea of how to syncronize these settings so only the frame rate changes?
Thanks..

In general there is a slight brightness change between 720/50p and 720/25p; 720/50p is just a bit darker, maybe 1/4 stop. That's something that happens when you go to 50p (or 60p).
 
If you have the shutter set to "off" you'll see the brightness difference. If you force the shutter to a set speed such as 1/120, there is no brightness difference.

Does scene files save shutter settings?

No, it only saves the syncro-scan shutter speed.

Be aware that changing modes can also change the shutter speed available. For example, in 720/30p I can set a shutter speed of 1/60th, but when changing to 720/60p the shutter jumps to 1/100th! So if you're toggling between 720/25p mode and 720/50p mode, and you're employing a manually-set shutter speed, check to make sure that it's actually staying the same. 1/120 stays the same, but 1/100 or 1/60th don't.
