Help with weird deinterlace
I have a bluray source (indexed in a .dgi file), PAL, and it has a weird deinterlace: it has 5 interlaced frames and 1 progressive.
Which deinterlacing filter should I use? And other thing, how to solve the "no function named McBob" message? Thanks. |

5i + 1p is a funny pattern. That's 1 additional field per 11 source fields. Ratio 12/11 is 1.09, which is (roughly) *double* the ratio of 24<>25 fps.
To avoid the message about MCBob, you simply don't use MCBob.

OK, this is what I do:
I have the BD fully ripped to the PC. This is the m2ts info: Code:

Here is the m2ts sample, trimmed with DGIndexNV: http://www.mediafire.com/?6m46ll9ytb4tr68 About the McBob thing, I'm actually trying to solve it to use it... |

The source is crap. It's a 25-->30fps conversion with sliding blending (similar to ConvertFPS, but actually it seems somehow different), and afterwards it has been phase-shifted.
Contact the dealer, and sing the "gimme my money back" song.

Match the fields with just TFM(). After that, you can enjoy the blending crappiness in all its glory.
There is nothing more that could be done. The blending is done in a funky unusual way, so that the blendreversal tools (like RestoreFPS) will fail big time.

OK, thanks, I'll leave it just with TFM(), if there's nothing more to be done...
What is the difference with TFM().TDecimate() and TFM(pp=0).TDecimate()? And what about the McBob? Why my Avisynth doesn't load it? Thanks. |

I had a feeling it might be Doctor Who or Torchwood!
Code:
bob.srestore # or a better bobber (qtgmc for instance) Planet of the Dead was released on Blu-ray in the same way (I did contact 2entertain to complain, but they had no plans to re-release), and I wrote an article on how I fixed it (which requires the PAL DVD): Restoring the Doctor Who Specials (scroll right to the bottom).

*deleted*
edit: Hoho, I fooled myself by just looking at TFM, and worse, not disabling the pp. Forget what I have or had written. It's indeed a blendbox-normconversion, with some chroma oddities. Srestore is mandated, but the chroma issues.

That is pretty much all you can do, without studying the video and trying to determine the chroma blending pattern, and then writing your own filter to fix it... just using srestore will give you a much more watchable result though - no more juddering pans. David |

So I guess I'll leave it like that. Will I see that black and white effect on action scenes or it will be almost invisible? 'Cos I remember watching "Children of earth" and every time someone was running I could see some black and white parts...

I can't see a lot of difference between srestore and repal on your sample clip, except that repal makes a better choice on one frame with particularly blended chroma and is slower. Maybe this b&w effect is something else and repal just happens to handle it better.
If it looks okay to you, it's okay. David |

Then I will have the BBC HD logo haha Look at these captures: http://www.mediafire.com/?dmtgl1pgfjl35wg In the source ones you can see the b&w effect with bob.srestore, although in the encodes the frames are equal in that scene. But look at a different frame on the encodes, there's the effect, but depending of the filters the color is b&w in different places. Which filter do you guys recommend, seeing the differences? I mean, for a proper visualization. EDIT: Forgot to upload the screencaps xDD Last edited by eXtremeDevil; 25th September 2012 at 16:01. |
