chroma ghosting errors
Software used: DGIndex, AVIsynth, loadcplugin, ibob, Virtualdub. The really weird thing is, I can't always replicate these errors, which means I can't pinpoint exactly where stuff starts going wrong. Has anyone else encountered errors like these? If so, do you know what's causing the problem?

The color distortions exist prior to exporting as still images, so it has nothing to do with png or Facebook.

EDIT: Well, I tried that, and it completely screwed up the field order. I tried separatefields, then converttorgb, then weave, but that didn't fix anything. assume tff, assumebff, and complementparity all failed. So I stripped everything out and went back to having nothing but loadcplugin and ibob, and now I'm getting an all new error: interlaced chroma ghosting! The gods have forsaken me

Perhaps if you posted a sample someone could have a look. |

I shall direct your attention to the following line in the OP:

EDIT: it occurs less often when using Bob or Separatefields instead of ibob, and while I THINK I remember this error showing up with at least one of those two (South Park + separatefields comes to mind), I also have a tendency to go two weeks at a time without sleep, which can severely affect memory... so ibob is the leading suspect in this case.

yes.
Code:
mpeg2source("101.d2v") loadcplugin("c:\ibob.dll") ibob()

NOT horribly-artifacted JPG images. P.S.: but I am very sure you already knew that. Last edited by filler56789; 2nd August 2016 at 23:01. Reason: add P.S. |

And no one uses iBob. Except Katie Boundary, I suppose. Its only possible use is to get back the 'original' field after being filtered. And if you're trying to IVTC or otherwise make your source progressive, you plain just wouldn't use it. Last edited by manono; 3rd August 2016 at 04:40. |

That's the part where we got stuck last time.
The key point here is that these errors cannot be reliably replicated, and that they only occur during deinterlacing. I was hoping that a problem with such unique characteristics would be well-known already, and that the cause would have already been identified. I doubt that you'd be more helpful if you had access to some untouched DVD footage just to confirm that this isn't a problem with the DVDs. Well, if ibob is the source of the problem, then that might be why I'm the only one who's experiencing it.

Then if you refuse to do as requested, there's nothing more to be done and no help to be provided. If you're asking for help, you post the script and a sample. Basic procedure.
If you're not asking for help then why does this thread even exist? I'll be happy to delete this thread if you like. |

If your car starts making a funny noise, do you take photos of the engine to the garage and ask them to diagnose it? You're showing an incredible amount of ingratitude. |

I'd prefer to wait and see if anyone knows more.
