I for one like to "tweek" my videos. By way of "tweek" I mean adjusting the color, saturation, gamma. etc. but have never known "what" all this tweeking is actually doing to the signal accept for what I'm seeing on my monitor. So, wouldn't it be nice to have a vector/waveform monitor as a software program so as we were making these changes we could actually see how they were effecting the video, all the "professional" editing programs have this ability. Would anyone else like to see something like this? Tweek...Tweek...Tweek...

Being a former video engineering technician, when settting up four cameras for a studio shoot or professional sports, and color matching all the cameras, the wavefore and vector were an essential tool. But that was in the NTSC signal days.
My question is, are the waveforms the same in the hi def digital format as they were for the NTSC format? I still work in the control room at times in professional sports. But the signal in the sports arena is still set up using the older waveform/vector scope because that's what we feed the Jumbotron.
As for white balance all the camera people shoot the same white object and the engineer hits the white balance button on the CCU (camera control unit) and all the cameras are color balanced. But they are still shading the cameras ( for gain and pedestal) constantly especially when you are shooting outdoors with the sun and shade changing.
This month I'm going back to shooting professional sports and hope to get into one of the trucks to talk with the engineers that set up the cameras and find out if the signal setup for high def digital format camera is the same at the old NTSC. The vector scope would be an asset for setting up the correct color temperature.

Paul and Ronald,
in photo & cam magazines when cams are tested they also show a vector image for HD cams
in the testreport. Thus I imagine there has nothing changed adjusting SD or HD cams via a
vector scope for NTSC/PAL signals.
The editing program Sony Vegas 8 Pro for PC use has also an integrated vector scope for color analysis.
