Colour noise being created by telecide filter

[DivxBr]

After a long tryout of several Inverse Telecine filters, to recover the 23.976fps pattern of some episodes, I get the best for the job: TELECIDE filter for Virtual Dub.
Unfortunately, this filter, is outputting the frames with a strange colour noise (specially visible on a scene with white letters on a black background - the letters begins to show some variable (across the time) colouring), that wasn´t present on the original video.
Can anyone give any hint?
Thanks for attention,

I have never encountered this myself, but I would definitely email Donald Graft about this (neuron2@home.com), who is supposed to be coming back from vacation tomorrow (he's the creator of the filter in case you don't know). I'm sure he'll be full of vitality to start coding on Telecide again! :D

Thanks.

I've tried myself write to Donald Graft, and didn't get any answer (probably because of vacation like you said!).

The problem occured when I was processing a TV captured video so there may exist any capture color noise that is hidden in captured video that reappears after the filter (because some delay in color/luminance info I think).

Stupid @Home lost all my mail while I was on vacation. If you still have the problem please mail me at neuron2@attbi.com. But I can tell you that Telecide isn't creating anything! All it does is reassemble matching fields. :-)

Thanks Donald for these filters:

I use Telecide with nearly every TV capture I prcess after (PAL)
and it works great (but isn´t really fast on my Duron 800) ;-)

Rendering rate is 11 f/s without telecide and ~6 f/s with...

(I have to buy a new mobo and cpu...)

The other one (Smartdeinterlacer) is highly recommended with EVERY DV file where the Mainconcept Codec is used.
I only use the phase shift with field swap after (so no deinterlacing) to get good MPEG2 / SVCD Files --> You can see that especially on fast moves...

Thanks a lot for these ones: I would have given up that damn thing without these 2 ones...

Thanks, Harald. I'm happy you find them useful. I can make Telecide much faster. I am adding it to my to-do list.

Really, the telecide filter was the more practical IVTC method I found (even having to make a two pass processing for decimate) specially TV captures. :)

About the noise, I don´t have the original files that showed that effect to me, but I´ll see if I can find other ones. I´ll keep in touch.

In captured videos, I usually reduce the video size 2 or 4 times (in both axis) to avoid fooling decimate filter with chroma noise in the luminance channel (poor comb filter).
