Blackmagic Ultrascope

[Nachiket Pangare]

Hello,

There seems to be no concrete information on the Blackmagic Ultrascope in terms of actually reading the waveform and the histogram.

My queries:

1) In the RGB waveform, what are the numbers to the left (0-800); the right side numbers seem to be the IRE's (0-100).

2) What does the composite mode show in the luminance waveform?

3) Has anyone had problems with the histogram? That is the most confusing bit.

Thank you,

Nachiket
