Decomb Telecide doesn't deinterlace. It just re-orders the fields to undo Telecine or to fix field-shifted streams.
After that process we (ideally) get the
original progressive frames back. No interpolation does happen.
Of course Decomb Telecide only works with Telecined or filed-shifted material. It does
not work on "true" interlaced video at all!
In your case the video appears to be field-shifted and Decomb Telecide
does restore the video pretty well.
Unfortunately there are some filed distortions, which cause these minor combing artifacts shown in your screenshot.
Putting a deinterlacer (e.g. Yadif) behind Decomb Telecide removes those artifacts.
Of course you could skip the Decomb Telecide filter and only use Yadif. This should remove the combing too.
But you probably get better quality, if the deinterlacer bases its decisions on the "fixed" stream instead of the field-shifted one.
The same way we
could simply deinterlace a Telecined stream, but we certainly shouldn't do that!
BTW: Maybe one of the Avisynth gurus could write a script to fix your field distortions in a smarter way
Appending Yadif is the quick and dirty solution to clean-up the remaining combing...
