Blackmagic Design's DPX handling is a complete mess, if that's what
you're referring to. It's something that can't be fixed, either. Their
codecs ONLY handle broadcast range. That means DPX is always scaled
from broadcast to full range. If you attempt to capture full range
using a BM card, BM's software will clip to broadcast range, then
scale to full range for DPX output. As I said, complete mess. The only
way around it is to write your own capture app using their SDK.
