Hallo everybody,
in this post there's a pretty infos about this problem:
http://www.premiumbeat.com/blog/yc-waveform-monitor/
Above all it says:
A special note for PAL editors: Unfortunately, Premiere Pro doesn’t seem to follow international standards for this measurement! In the usual PAL system you measure in mV (millivolts) where 100 IRE = 714mV and 0 IRE = 0mV (IRE 7.5 = 53mV) but for some reason Premiere uses Volts and has the range 0.3 to 1. As long as you know about the differences this shouldn’t cause you many problems.
but I didn't understand ...
at the end, which is in Pal (V) waveform the threshold?
I think we have this correspondence between IRE and mV (Volts):
IRE = 100 Pure Withe
as
V = 1.0 (but the right White PAL V value is 0.714)
and
IRE = 0 Pure Black (but the right Black PAL V value is 0)
as
V = 0.3
It seems work rightly.
