A DP is asking me to use an Arri Max when shooting 2000fps with the phantom flex.

Is this possible? The arri website states that their ballasts can go over 1000 fps at 1000 hz. Any info on this would be appreciated.

You need to make a test) I shot 1000fps on phantom 64 gold and use tungsten Arri 24kW ,10kW. For 2000 fps and Hmi high speed ballast is high risk of flicker...

Ya I would test to see if you notice any flicker. Im curious about this now. I know when we did high speed work on sport science with the Phantom over 1000fps we would use 12K Maxi Brutes and Dinos and they were fine as long as you dont dim them.

 

Is there a reason he specifically wanted you to use the Arrimax?

 

Found this link as well not sure if it helps much

IMHO, I would be calling ARRI not relying on their website or asking if anyone here had "gotten away with it".  Lacking a definitive answer from ARRI, any reason why you can't light it with large Tungsten sources? 

 

Who's will ultimately take the blame for failure?  You will.

JD thats a good idea. I bet you can call them and get an answer no problem. But if you can, if it were me I would try to light with larger tungsten units to just eliminate the possibility of flicker.  I understand you may not have it in the budget or you already have the Arrimax. I am curious what you find out about the Arrimax i cant find anything online about info over 1000fps
