virtualdub chroma smoother vs avisynth

[video]

Hi,
I found the vdub "chroma smoother" with mpeg2/4:2:0 config setup perfect for my VHS project. How can I use a similar one in avisynth? It looks like the filter is vidrtualdub internal.
Thanks.

CNR2 is a pure chroma smoother, as is SSIQ. You can also use any of the many avisynth smoothers, cleaners, and denoisers; for the ones that don't have a chroma-only mode, you can use something like:
new=filter()
mergechroma(last,new)
To ensure that the luma is unaffected.

okay I will use cnr2... but other problem occored.

---------- avs script begin -----
LoadVirtualDubPlugin("MSUDenoiser162.vdf","msu", 0)
SegmentedDirectShowSource("why me.avi")
Cnr2()
ConvertToRGB32()
msu(75, "100.0")
LanczosResize(640, 480, 14, 4, -10, -4)
convertToYV12()
---------- avs script end -----

meGUI requires convertToYV12() - but if I put it in, then just blank (black) image comes out...

Start by commenting everything out, and go from there. For starters, does DirectShowSource on its own output anything? If so, keep commenting things in until it goes black, you'll find the problem. Use virtualdub to test, no megui.

okay. the source is a typeii dv-avi (dvc, coming out from canopus advc55). if i have the segmenteddirectshowsource() only i have picture. when i put in a converttoyv12() - then no picture :cry:

I bet you have picture, but you can't see it. You need to install a YV12 codec, like XviD.

i have coreavc, ffdshow. is it a must to have xvid installed to see yv12 output from avisynth? :confused:

however when converttoyv12() is in the script megui cannot pull any frame out - stalls, no progress.

i have found something, called helix YV12. If I install that will it fix the problem?
