White clip default setting is 105% so the camera can record anything above 100%, so having zebra
2 set to 100% it indicates that last bit of range you have available when using the standard rec709
gamma. It is recommended that when you are using hyper gamma 1 or 2 that you set zebra 2 to
90/95%. When using CineEI zebras measure the MLUT output, if you use the rec709 MLUT then
normal zebra levels should be used (Zebra 1 = 70% and Zebra 2 = 100%).
