Edit- update in 2nd post
Trying to set up GraphStudio/Avisynth/MPHC to run the code below, so I can use Avisynths histogram to setup my TBC proc-amp for capture.
I am using a Pinnacle 710-USB capture device.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
In GraphStudio there are three Pinnacle 710-USB filters that show up, I have tried all three.

Pinnacle 710-USB CrossBar

Selecting only one of the filters, I save the graph file as cap.grf.
When I go to open the avs file in AvsPmod it gives me the error:
DirectShowSource: GRF file does not have a compatible open video pin. Graph must have 1 output pin that will bid RGB24, RGB32, ARGB, YUY2, YV12, YV16, YV24, Y41P, Y411 or AYUV

When I try open in MPHC, I get two errors and then the same error as AvsPmod.

Please help, what am I doing wrong?
Other points that might be useful:
- Drivers are install for Pinnacle 710 - no errors in Device Manager
- Capture in VirtualDub works - I get video

I played around and got Graph Studio working

But I still get the error below when I try to open my Avisynth code in MPHC, VirtualDub or AvsPmodDirectShowSource: GRF file does not have a compatible open video pin. Graph must have 1 output pin that will bid RGB24, RGB32, ARGB, YUY2, YV12, YV16, YV24, Y41P, Y411 or AYUV
What am I missing?

If it's just for adjusting the proc-amp it is probably easier to right-click the orange Pinnacle 710-USB USB box, select Properties.... and go to the video proc amp settings tab.
Or as long as the waveform/histogram is 'reasonably well' within the limits and is not clipped, leave the capture proc-amp setting their defaults and do the final adjustments in post processing.
See for example the recommendations in your other thread:
Below works here for the GV-USB2. Try similar for your Pinnacle:

Thanks Sharc, I'll give that a shot using your GV-USB2 setup. I ended up giving up and just using the VirtualDub histogram for this tape.
I can't find the Huffyuv filter in Graphstudio, so will have to play around and figure that out.
I'm actually using the proc amp on the TBC, so it makes it a bit easier.
VideoYak, I've had a go at using the AVISynth histogram in MPC too. I found that success seems to be dependent on the digitiser. My GV-USB2 and USBLive2 would not do it, with error messages in MPC, but my Startech USB3HDCAP worked like a charm and MPC was great for setting the levels. Unfortunately, I can no longer get my 710-USB to function at all under Win 11 so can't check it.
This filter graph works perfectly here for the USB-live2. I think you prefer lagarith as the compressor, so I inserted it instead of Huffyuv (which works as well btw.)
Maybe you have to install the LAV filters.
This is the script which plays fine with MPC-HC, Vdub .....
DirectShowSource("USB-Live2.grf",audio=false,framecount=10000) TurnRight().Histogram().TurnLeft() # horizontal waveform monitor at the top of the frame ConvertToRGB32(matrix="rec601")

What is your exact process for inserting that codec box?
