Hi,

I have these captured video which I'm in the middle of transcoding to x264. Trouble is, one of these is from an analog antenna source (other ones were from STB) which at that time had a fairly poor quality antenna so it's fairly noisy, in particular has vertical lines. I've been using FFT3DGPU on my not so noisy videos but although I've tried increasing sigma (normally I use 2.3), it's not enough. I'm thinking other filters may help more but don't really know what to use. I don't really care much about time taken, I have a dual core A64 and an 8600GT and since it's only one file, 100+ hours is okay if that's what it takes (but hopefully it doesn't come to that).

I've given 3 samples but if you need more, just tell me. These have not had any modifications done to them other then cutting with TMPGEnc Editor. Also I have over half of this file from the cleaner STB source, i.e. the exact same video but cleaner. I don't know if this will help at all, but if it does, just ask and I'll post some videos showing the same thing. (I'm of course more concerned with fixing the part that I don't have from the STB source)

LoadPlugin("C:\Multimedia\x32\AviSynth 2.5\plugins\FFT3dgpu.dll")

DGDecode_mpeg2source("K:\FOD\Frontier of Dreams-2005-12-10-0.d2v",info=3)
ColorMatrix(hints=true,interlaced=true)
Load_Stdcall_Plugin("C:\Multimedia\x32\megui\tools\yadif\yadif.dll")
Yadif(order=-1)

FFT3dgpu(sigma=3.9, bw=48, bh=48, bt=4, mode=1, ow=24, oh=24, precision=2, plane=4, degrid=1, wintype=1)

N.B. The deinterlace settings were chosen by megui, there are a number of scenes from old videos in this documentary so possibly a variety of stuff with interlacing and without interlacing
