White Balance has a mind of its own

Dummy checked this several times...it's not on Auto. It does this is both A and B. Shifts from a cool tone to a warm green tone. When I FF scrub through the footage in FCP it almost looks as if it's rhythmic.

Here's a link to the evidence...

We have six HMC150's here at work, and this is the only one that we've had a problem with. Still under warranty...just wondered if there was a known issue?

Were you perhaps shooting under fluo lights with a higher shutter speed? What you're describing is exactly what would happen in that scenario.

Kino Diva 200s, 24p, 1/48.

I've shot this scene dozens of times under the same condiitions with several 150s and a HPX500, and never experienced this.


EDIT: the blue drop is lit with a streak from an ARRI 300. I can def see some shifting in those parts of the image, too.
