the concept is two fold:

1) drag your shutter down to the lowest speed to stop motion, ss 1/80 - 1/40 depending on how still they are and how zoomed out you are. you might need more ss if they are moving a bit.

and

2) raise you iso to at least 400, but even higher, iso 800 if needed for the effect to bring in ambient light

Or you could approach it methodically:

  1. Get a standard ambient meter reading (zero compensation).
  2. Use settings that deviate from that to reduce image brightness by a chosen number of steps, e.g. -1 1/3 (aperture for desired DOF, shutter for desired motion blur up to max sync, ISO to match).
  3. Set the flash output to give the desired brightness on the subject (FEC in E-TTL or directly in manual).
