Avisynth: best Deinterlacer script?
anyone know of a good line to add to the optimal script for deinterlacing a dvd rip ntsc music video?
I'm tryin to put together my own little music dvd of nusic vids I have on the dvds I bought. |
I always use FieldDeinterlace (to put just after the load of the source).
But I'm not the "guru" of deinterlacing there, and also I deal with PAL that can be different. |
cheers I'll try that out.
so the line would go something like: Code:
Mpeg2Source("C:\source.d2v" FieldDeinterlace) |
Ugh...
Code:
MPEG2Source(....) http://www.kvcd.net/forum/viewtopic.php?t=8678 |
cheers dialhot I'm not so up on deinterlacing myself but I know tmpgenc doesn't do the best of jobs with deinterlace.
|
would you know what plugin do I need for Smoothdeinterlace??
|
Just look for the word "smoothdeinterlace" on this page and you will find your answer :-)

well I had a read through that post by incredible and I'm more confused than I was lol so I just went with FieldDeinterlace() seems to do the job fine.

hehehe what I might do isdo a go with FieldDeinterlace() then smothdeinterlace an see which looks better lol thanx for the help guys.
|
well fielddeinterlace works Smoothdeinterlace doesn't I either get a 5 second still shot of staic or I get a blank output.
|
Always agrre with Incredible saids, Fielddeinterlace works fine just for PAL interlaced sources.
For NTSC interlaced sources he recommends that I posted in my previous post. And as you can see, you can use bob() rather than smoothdeinterlace. |
well I downloaded dgbob plugin used dgbob() and got again blank video output, so I thought I'd use the script in your code and got a 3 second blank video output.

zorry I wasn't meaning to sound like I was having a go I was just commenting on what happend. Think safe bet is just put up with fielddeinterlace()

You do mix up something!
Every Bobber like KernelBob(), DgBob(), Smoothdeinterlace(doublrate=true) .... does quick said not really deinterlace in the known way. He does separte the fields and resizes them to full frameheight! Means the full fieldrate containing full video vertical size comes out. Soid in easy words. In pal this is 25*2 or in NTSC 29.97*2 Sharfisbrains function needs NO simple deinterlacer BUT a bobber in front! Means the ones I mentioned above. BTW ... Smoothdeinterlace() is not the state of the art, try DgBob() or KernelBob(). Just deinterlacing a 29.97 to 29.97 makes NO sense! - if your stream is true Video like Concerts, Documentations etc. THEN try Scharfis_Brains function or even the new MV method posted by boulder below in the 60ito24p Thread. - if your stream is just telecined (Hollywoodmovie) then do a IVTC like explained in my Interlacing-Thread. A bobber is used for instance if you want to do a HQ interlaced resizing: Avisource("YourInterlacedVideo") AssumeTFF() # The right Fieldorder here! Bob() #.... bobbing (twice the framreate will come out) LanczosResize(... regular FULL HEIGHT settings ...) separatefields() Selectevery(4,1,2) # Inverse the bob Weave() For Bottomfield First: Avisource("YourInterlacedVideo") AssumeBFF() # The right Fieldorder here! Bob() #.... bobbing (twice the framreate will come out) LanczosResize(... regular FULL HEIGHT settings ...) separatefields() Selectevery(4,0,3) # Inverse the bob Weave() |
when I tried the smoothdeinterlace and dgbob and got a blank output but fielddeinterlace worked fine for me so I think for future reference I'll stick with that as I couldn't seem to get it to work

Sure, you can deinterlace with FieldDeinterlace but you'll end up with a 29.97fps stream and that means 25% more frames to encode :arrow: a lot lower quality.
You're much better off using the 60ito24p method described in that thread pointed to you. Simply: Code:
MPEG2Source("path\clip.d2v") |

Said again: DONT!!!!!! just deinterlace 29.97 Videos as still a 29.97 stream with blendings would come out!!! Use the function Boulder quoted above! |
