Hi,

Here is my equipment
Sony PAL Hi8 Handycam (TBC on) -> S-video out -> Cypress 1T-TBC -> Pinnacle USB-710 -> VirtualDub (Huffyuv)

The TBC has a simple Proc Amp that has the following settings:
Sharpness
Hue
Color
Brightness
Contrast


Brightness and contrast I understand and plan to use Avisynth histogram function via Graphstudio to adjust settings before capture. I prefer the Avisynth histogram to Virtual Dub's one.

I found this code posted by jabago
Code:
DirectShowSource("cap.grf", audio=false, framecount=100000) 
TurnRight().Histogram().TurnLeft() # horizontal waveform monitor at the top of the frame
ConvertToRGB(matrix="rec709") # the device is putting out rec.709
Question 1
I don't understand the purpose of
Code:
ConvertToRGB(matrix="rec709")
Do I require that?

Question 2
Is there a waveform monitor/histogram that will guide me with what to do for Hue and Color pro-amp settings on the TBC? I don't have a great eye for Color and really prefer working off something like a histogram. Any guidance here is much appreciated.
