Deinterlacing properly.
Hi; so essentially I would like to know how to deinterlace properly - as in 100% no ghost frames?
How do threshold's play into this? Is there a general guide as to what to do? Last edited by Guest; 20th May 2010 at 21:19. Reason: 6 |

What sort of framerate (time) are you looking to spend and what output do you require (25->50fps ok, or want 29.97 to 24, etc)?!?
Avisynth with TMGC is probably the best deinterlacer there is, but it's slow Bobbing also produces reasonable results, but doubles the frame rate ... 7 |

Material is NTSC (not FILM) at 29.97fps, with BFF.... kernel/field/telecide/yadif pretty much all the deinterlacers that I've tried result in ghosting. I suspect I need to tweak setting, probably theshold parameters, but generally I don't know what im looking for...
Where can I download TGMC filter... google isnt providing any direct links :'( Last edited by pissed; 21st May 2010 at 12:50. |

Some of the deinterlacers mentioned don't leave ghosting behind. I suspect your problem isn't the choice of deinterlacer (since you'll get ghosting however you deinterlace), but using a deinterlacer at all if it isn't called for, if the problem is, as I and txporter suspect, a PAL2NTSC field-blended source. Advice without a sample to examine is kind of hit-or-miss anyway, so please make available to us a 10 second untouched sample, one showing steady movement.

10 sec clip. Video is kinda old, which I think makes the situation worse... |

The easiest way to fix it is with:
Yadif(Mode=1) RePAL() Both filters can be found here: http://avisynth.org/warpenterprises/ |

manono's approach is easy and pretty fast. If you are noticing bob flicker that is annoying to you, you can try TempgaussMC in place of Yadif. It is MUCH slower than simply using Yadif, but the results are great. You can also use srestore(frate=25) in place of repal() if you want to get exactly 25fps rather than 24.975fps.
I use something like this to restore PAL video from NTSC dvds: Code:
setmtmode(5,0) loadcplugin("C:\Program Files\Avisynth 2.5\plugins\yadif.dll") MPEG2Source("Path\To\video.d2v") setmtmode(2) TempGaussMC_beta2(1,1,1,edimode="Yadif",Smode=1,SLmode=1,Sbb=0,SVthin=0.0) #repal() srestore(frate=25) removegrain(1) |
