So in my quest to further mess with the camera, my latest gag reel is working with the RGB+S. I wanted to produce a signal akin to VGA as capture cards for VGA are a dime a dozen.
In this case since I don't know whether the CCU gets the sync from green or composite, I opted to use an LM1981 chip to extract the vertical and horizontal signals from the composite out.

And this worked, to a degree.


The monitor happily locked to the signal, and the frequencies are correct for NTSC.
The problem is, the image produced is extremely dim and almost purple.


In person, this is much much dimmer, almost unnoticeable.
While I get there is going to be some nasty noise due to my current construction, I am having trouble finding out why the signal is just not good. Is there something I am missing with the RGB? I am thinking either I need to amplify the RGB lines or I am misinformed on RGB+S vs a VGA signal.
