Shooting with an Arri SR1 how could I capture strobe lights? Do they need to match the frame rate exactly? What should I know? Thanks!

How are you using the strobes? Are they random flashes for a "party" effect, a constant flicker, or synched to the movement of the film for exposure?

Without synching the strobe unit to the camera, some flashes may be exposed on film properly, some partially, and some not at all. As a rule, the flash that you see in the viewfinder is not completely exposed on the film, although it might be partially exposed.

The closer your strobe rate gets to your shooting frame rate, the more visible the "phasing" or missed flashes will become. Slower strobe rates may hide the "missing" flashes better (the ones the camera doesn't capture), and multiple strobe units can make the effect more random and less noticeable anyway.

Unilux strobes can be synched to a camera with a synch-pulse output. Offhand I'm not sure if the SR1 supports this, although it might.
