Opening GraphEdit Files in AviSynth

[koberulz]

DirectShowSource("graph.GRF", audio=false, framecount=1000000)
ConvertToYV12()
Histogram(mode="color2").TurnRight().Histogram().TurnLeft()
#ColorYUV(analyze=true)

I use it to set up the proc amp before capturing, in cases where content clips on the default settings. It's worked fine in the past, but I've been away from it for a couple of years and now can't get it to open. In AvsPmod I get a black screen with the two scopes, in MPC-HC I get a “cannot render the file” message in the status bar. I am using a different computer, so it's possible I'm missing a plugin or something that I need, but I'm not sure what it could be.

You may have to revisit your "graph.GRF" filter graph.

And try by adding at the end of your script

ConvertToRGB32(matrix="rec601")

yes, regenerate the graph from GraphStudioNext as first step, including all necessary "filters" of your capture card

Revisit in what way?

ConvertToRGB32(matrix="rec601")

Makes no difference.

Revisit in what way?

Open your graph.grf in GraphStudioNext and design a filter graph which works for your capture card.
This works here for my GV-USB2 for example:

I've opened it, and it all looks exactly as it used to.

I had it set to composite in rather than s-video in. Now it works in AvsPmod. Still can't render the file in MPC-HC, though.

[Sharc]

Try different renderers of MPC-HC.
How does your filter graph look like?

[koberulz]

Different renderers?

[jagabo]

Different renderers?

MPCHC -> View -> Options -> Playback -> Output -> DirectShow Video -> choose renderer from pulldown

But I think the Source Filter is more likely to be the problem.

MPCHC -> View -> Options -> Internal Filters -> Source Filters...

Make sure AVI and DirectShow Media are enabled.

[koberulz]

Wait. It's 32-bit AviSynth and 64-bit MPC-HC. I have just plain MPC here...which also works fine.

Sorted.
