I've got PAL video captured with tvtuner
Video: 704x576 (1.22:1), 25.000 fps, IBM Motion JPEG including Huffman Tables ~19953 kbps avg, 1.97 bit/pixel

Sample (http://rapidshare.com/files/25629114/Sample.rar)

I need to denoise (clear) this interlaced video and then deinterlace it. Is there any recomendation for it?

I've tried TDeint + EEDI2 AssumeTFF()
interp = separatefields().eedi2(field=3)
tdeint(mode=1,order=1,edeint=interp)

But the result is far from perfect for me

McBob is too slow and gives some colored noise

single frame screenshots - especially in JPEG form tell us very little about the source.

Link (http://en.wikipedia.org/wiki/Comparison_of_one-click_hosters)to an unprocessed sample so that we have something to work with.

I think the first shot looks ok, just clean up the chroma with fft3dfilter or fft3dgpu if you have a good video card (Pixel Shader 2.0) maybe fft3dfilter(plane=3, sigma=3).fft3dfilter(plane=0, sigma=1, sharpen=.5) is a place to start..

Is this combination fft3dfilter(plane=3, sigma=3).fft3dfilter(plane=0, sigma=1, sharpen=.5) for use with interlaced video?
O I should deinterlace it before? I think it will be better to clear video before deinterlace

Hmmm... unless fft3dfilter has an option to process interlaced material I think you'll need a SeparateFields before and a Weave after fft3dfilter, as IIRC broadcast TV is broadcast field by field, so both fields in a frame will have different noise.

np: Richie Hawtin - Seiltänzer (DE9 - Transitions)

I used to do that till i realized that fft3d doesn't function properly this way. It's hard to notice, but using fft3d this way usually leaves small combing for some reason. It'd be hard to spot though unless you look really hard.
