PD-170 real IRE or % for adjusting video monitor
Posted 02 March 2008 - 02:36 PM
Please help me fast i'm tired !!!!!!
Ok! Let me explain....
Shooting with a classic Sony PD-170 is always a technical adventure...
For this....Pd 170 is Digital OK ! but my monitor is a classic tube analog... I have to calibrate the monitor and I use an SMPTE signal OK ! But when I SET-UP my camera (o or 7.5) I remember this.... 0 IRE is the real black for digital world....7.5 real black for analog world.
In the pd 170 menu this is not IRE but % ( o or 7.5 ).
If I understand the signal on the ccd is DIGITAL but the signal from the RCA output ... is.... analog on my monitor !!! CONFUSION.... What is the best SET-UP ??? 0 or 7.5 ???. Looking at many books about digital cameras , the manufacturer (Sony) add 7.5 IRE to their analog output !!!!!
Whats is the best SET-UP for shooting whit tis camera and whst is the best way to calibrate the analog monitor ??????
Thank you everyone

The only time you have to worry about changing the calibration (other than checking it periodically) is if you change signal being fed to it (for example, if you switch cameras or change the setup level in the camera).

When the time is come to tranfert in the computer....
Using a Fire Wire.....Is this real that the output ADD 7.5 IRE to my images??????
Many books talk about this ...... I really don't understand this double technology (digital and analog working in tandem.
But it's make sense that the signal (digital) feed in an analog TV have to be add by 7.5 IRE to respect the broadcast analog BLACK. But show after the editing my image look greynish.......
Sorry for this confusion but....
Tank you All
