Hi maybe this is good to adjust the capture cards internal proc amps or external proc amps before you capture
i use Avisynth and Input Capture Card as Input Source and i use VirtualDubs Color Tools 1.4 for the Scope in avisynth

Avisynth Plugin VideoInputSource.dll you get from here https://forum.doom9.org/showthread.php?t=170311 this works good with Ati All In Wonder Cards

Here i did find the Function how to use VirtualDubs Color Tools 1.4 in Avisynth https://forum.doom9.org/showthread.php?p=607494

Here you get VirtualDub Color Tools 1.4 Plugin http://www.trevlac.us/colorCorrection/colorTools.html


For Ati all in wonder i use VideoInputSource in Avisynth

blackmagic intensity shuttle did not work with VideoInputSource i had to use DirectShowSource and GraphEdit file and ffdshow


i did create a txt file that i did rename to VD_clrtools.avsi and put it in Avisynth Plugin directory this is the code inside the VD_clrtools.avsi file and you have to change the LoadVirtualdubPlugin path to match yours in the code
Code:
function VD_clrtools(clip clip, int "mode",
			\ bool "NTSC", bool "stdDef", bool "rng255",
			\ bool "luma", bool "red", bool "green", bool "blue",
			\ int "hotFixMode", bool "showWFMgrid")
{
  LoadVirtualdubPlugin("C:\Program Files (x86)\VirtualDub_1_9_11\plugins"+"\clrtools.vdf", "_VD_clrtools")

  return clip._VD_clrtools(default(mode,0),0,0,
			\ default(NTSC,true)?1:0,0, 
			\ default(stdDef,true)?1:0, 
			\ default(rng255,true)?1:0, 
			\ default(luma,true)?1:0, 
			\ default(red,true)?1:0, 
			\ default(green,true)?1:0, 
			\ default(blue,true)?1:0, 
			\ default(hotFixMode,0), 
			\ default(showWFMgrid,true)?1:0)
}

d2=StackHorizontal(V,V3)
s=StackVertical(d2,d1)

Great info!!

I have and use the Drastic SDIscope for adjustments before capturing with an ATI card. Works well but you need, at the bare minimum, an AJA LHi card to make it work.

Still looking for a software videoscope solution to use during capture. I have not been able to get any videoscope software to run on my XP machines while I capture. I can do it if I capture uncompressed 8/10bit converting the analog signal to SDI on a Win7 machine.

Thanks again for the info!!
