Lighting issue - Profoto B1 off-camera flash kit – sequence of photos, movement

[gosia1234]

I'm going to be photographing a footballer doing a trick with a ball (called around the world, ref:*https://www.youtube.com/watch?v=6V1l1nfKK5M) and I need to photograph a sequence, of about 5 images while he's doing that. I'm using a Nikon D700, I was advised to photograph using a shutter of about 1/1000 sec and using Profoto B1 off-camera flash kit (http://www.bhphotovideo.com/c/produc...monolight.html).


The trouble I'm having is the flashes do not recycle fast enough, so when shooting a fast sequence the lights are uneven, or don't fire. I found that you can use the flashes in a Quick Burst Mode, which means the following:*When the output is set to three stops below full power, you will empty 1/8 of the tank with every flash, which means that you can flash eight consecutive times with almost no delay in between.


When setting the camera to the flash/bracketing option of 1/135 which allows me to photograph on any chosen shutter speed with flash, and shooting on a range between 1/500-1000 sec, the flashes lock to the range 8-10 (10 is max) and I can't reduce them any more than two stops, the Air TTL-N remote switches into the high sync mode - and still flashes don't recycle fast enough and are uneven if I attempt to shoot a sequence.


I'm really struggling to find a solution to this, so I would appreciate any advise on the above and how I can improve the situation and the set up to get this right. The location of the photoshoot means I won't be able to plug into the mains.
