motion artefact with tmpgenc

[Guest]

Archived from groups: rec.video.desktop (More info?)

I am transferring vhs tapes to DVD using dub to DV tape, editing in
Premiere 6.5, frame serving with AVI synth, mpeg encoding with
tmpgenc, and authoring with DVDit Lite. Generally things have gone
well, but am now having a proplem. When objects with straight lines
move vertically, there is a criss-cross type artefact on the vertical
edges. I have narrowed it down to mpeg encoding or beyond. I am
using cbr 8000. I have not previously encountered this. Also, scene
changes have a flicker not seen before. Any help would be
appreciated. Thanks.

change top field first to bottom field first or vice versa

There are many, many variables in tmpgenc that can affect video output and
cause artifacts. At 8K CBR, I normally wouldn't expect problems, though the
level you set for motion search is critical. Take a look at this website,
which gives excellent tips on how tmpgenc should be configured for maximum
quality results.

I don't believe it's reversed fields--I have not changed that. What
is the web site? Thanks

Since you're using DV... what setting do you have for
field order in TMPGEnc? Possibly, TMPGEnc has guessed
wrong.

For analog captures... field-order is (IIRC) "A" first.
But for DV, it needs to be set to "B" first.

Reversed fields would cause jitter, but not the type of artifacting that the
OP described.

Not always. By using Avisynth's ViewFields plugin, you can analyze the
clip, and find the truth,

Good pointer... (I left out the "usually")

Thanks to the people who offered suggestions. I tracked down the
problem to the encoder being set to non-interlace. Don't know how
that one slipped by. Thanks again.
