Call for script examples filtering VHS source
Could some of you filter experts give me some good advice on filtering for this source I captured from VHS. I've posted 2 clips (high bitrate xvid from lossless source). The first (notice color bleeding and slight background noise) is the intro which should probably be filtered different than the second (main movie and live action).
intro middle I'm not very familiar yet with advanced filtering and would greatly appreciate filter suggestions and script examples. I'll probably have to do something in this format to isolate sections: Code:
source=avisource("mpm.avi") intro=source.Trim(0,1489) mid=source.Trim(1490,82812) end=source.Trim(82813,86031) intro.ConvertToYV12().awarpsharp().ConvertToYUY2().peachsmoother().dctfun4b(50,50) Any advice is appreciated. Chip |

Thankfully, your source is already very good; one place to start would be something like this: Code:
Telecide(guide=1,post=2,show=false) Decimate() DegrainMedian(interlaced=false) |

Anyways it is better to IVTC the source.
There mainly are two reasons: 1) Most common filters only work with progressive footage 2) 24fps yields better quality than 60i when compressing to DVD Of course, if the video is a hybrid (24p, 30p and 60i mixed) then IVTC isn't a good idea.

Scharfis,

I think the video is a straight telecine last I looked at both animated intro and live video footage. Particularly with filtering, I'm trying to find an effective way to eliminate the color bleeding in the animated intro (see first post for link). I've searched and found a few posts that use fft3dfilter, but playing with the sigma and plane settings does nothing. Should I be trying something different for color bleeding?

How much did you pay for the Panasonic AG-1980?
And yes, you do want to IVTC because you'll be able to:
All you need to do after encoding your 23.976 source to mpeg-2 is to add the 2:3 pulldown flags with dgpulldown by Donald Graft. I do it all the time and everything displays fine on my real tube CRT television. |

Can anyone assist with denoise filtering (in the middle section at least) with something like fft3dfilter? I've tried many many times to configure it to best suit the source but the results are almost null. I'd like to consider some sharpening afterwards, something like seesaw.
Would someone be willing to take a look at the mid section for me and advise, if nothing else, on a good fft3dfilter config? |

This:
Code:
FFT3DFilter(sigma=6,plane=3,bw=32,bh=32,bt=3,ow=16,oh=16, interlaced=true) |

Thanks for your example. I used this and modified it just a little to be:
Code:
AssumeTFF() Interp = SeparateFields().SelectEven().EEDI2(field=1) Deinted=TDeint(order=1,field=1,edeint=Interp) TFM(order=1, Clip2=Deinted) TDecimate(mode=1) FFT3DFilter(sigma=6.0,plane=4,bw=32,bh=32,bt=3,ow=16,oh=16, sharpen=1.0) Is plane=4 a bit much in this case? Perhaps too smooth? Also, I'd like to use jdl-applyrange to isolate and filter the intro. and credits with one set and the middle (live action) with another, only when I read the cautions in the file it says not to use it with anything that modifies frame rate. How can I used this if I have to IVTC? As for the intro. and credits (which are animated), I specifically want to get rid of the chroma bleeding in this example as well as denoise some clicks and scratches as can be seen from the clip in my first post. Any ideas? Or can at least someone tell me what appears to be the biggest problem in the clip (the proper noise name) from the standpoint of filterability? I've been scouring the forums for the past 6 hours and trying every derainbowing and colorbleeding script and plugin I could find with the results either not affecting the target noise or affecting the picture in other ways. I'm going to petition my university for an "AviSynth Filtering 1101" class I think Last edited by chipzoller; 14th January 2007 at 03:49. |
