Hiya,
I think you and Romildo are suffering from similar problems. (And I
just got Romildo's post, too --- the re-ordering and delays on the
Sourceforge lists are really crazy these days.)
I tried to use some automatic guesses from y4mscaler, but they did not
do what's IMHO right.

have roughly a 4:3 display aspect ratio? Hmm... then it seems like
it has roughly a 3:4 pixel aspect ratio. Not a common SAR.

Example:
I have an NTSC AVI with 640x352 16:9. I want to transcode it to MPEG2
NTSC 4:3 (720x480).

taper, versus blurring/noise-reduction via lowering the cutoff frequency

In terms of visual appeal, that's probably an empirical question. But

will disappear.
The sinc* kernels are very bad at removing noise. IMHO, the
cubic* kernels are better for this job...
A factor to consider (for why the sharp-cutoff

Hallo
I can see light vertical stripes in bright scenes in my encoded result.
I can't see them in the original AVI (Xvid).
How large ist the stripe ?
Do you scale (guessed from the -Z option) the picture ?
If yest does it also happen when you don't scale it ?

I tried without scaling and still have the artifacts. Maybe it's the

That's what yuvdenoise is for :)
Well, sort of. It removes noise temporally. But it would be nice to
have a spatial lowpass filter in the toolbox also to reduce noise that
way.
