Any tips or tricks to get CMOS sensors to capture gun muzzle flashes?

One possible solution could be to simply use no shutter: in other words have each frame expose for the entire 1/24sec duration. This will change the motion characteristics of these particular shots drastically, and rather unpleasantly in my opinion, but you will be guaranteed to capture every muzzle flash. I'd advise checking out cinematography.net; I'm pretty sure they've got an article on this subject.

I thought it was the CMOS because it's a known thing CMOS can't capture things like camera flashes and police lights because of the refreshing rates so I thought the same was applying here. I will give it a try with a 1/24th shutter.
How about slow motion at 60p? I can see the shutter setting being even a bigger problem here.
I will check cinematography.net as well.

A video camera with a 360 degree effective shutter should have very little problem with fast burning blanks. The only issue is if it has a rolling shutter, in which case the shutter edge passage could hit the area where the flash is, and get cut off. Look at some of the threads about strobes and the Red camera, there are examples that show the shutter edge being caught by a strobe.

Also, there has been talkings of getting some cap firing machine guns. I'm thinking firing caps will also be characterized as fast burning?
