If memory serves, the only clipping that happened was in the straight, unprocessed screenshots. That means that they were overexposed by several stops in post... but the data is *actually* there. When we actually spent some time working with the pictures, all overexposure disappeared.
It's like the first time you put a negative in a film scanner. It'll look like absolute overexposed crap until the operator spins a few knobs. Those screenshots were before we spun *any* knobs.
