shimmering credits = bad transfer OR player setting?

[Guest]

I have an HLD-X9 using S-video to an i-Scan Ultra, then to a Sampo SME-34WHD5
HDTV.

When I watch the end credits of the Japanese LD Sakura Wars, I see the kanji
"shimmering" or "pulsing" (not quite the right word) as they scroll up the
screen. I do not know the word for this, but it's like the top line of the
character moves before the bottom, "stretching" the character, then the bottom
catches up.

I thought it was something to do with line doubling, but I can't find a way to
change the i-Scan settings, or the X9 settings, or the TV settings.

What's going on here and is there any way of stopping it? Is there a setting
somewhere I'm missing to disable this effect?

TIA,

H. Brown

What you describe sounds like an interlacing artifact, but you shouldn't
be seeing those with your combination of equipment. Do you see this on
every disc, or just the one?

I am not sure, I just noticed it. I am going to try troubleshooting it more.
Does this artifact have a name (like moire, dot crawl, etc.)?

The way you describe it is odd. I'm inclined to think this is a one-off
thing from a bad video transfer. If you see it on other discs, post back
here.

Okay, I tested some other LDs. On a AnimEigo CLV disk with computer generated
scrolling credits in English, no such problem. No doubt AnimEigo tried hard on
the transfer.

On a Japanese LD (CLV) from the Ghibli set, scrolling Japanese credits
exhibited some shimmering, but not universally, and simple characters did not
shimmer but scrolled smoothly. None of them exhibited the "stretching" and
"squishing" as I saw on the Sakura Wars discs. The shimmering only occurred on
the more complex characters, and I'm thinking this is just the line doubler
working hard to interpolate, when the original disc resolution just isn't
enough to fully define the character. Also, it's not CAV, thus every few
frames there is some fuzziness hence the shimmering. That's my unexpert
diagnosis.

On the Sakura Wars, which is an OAV, probably not done on film, is it really
possible that there was an interlacing artifact during encoding? I'm going to
research this. Any good explanations out there?

I still need to test some more discs (now I'm looking for scrolling Japanese
credits on CAV discs, and will compare to scrolling Japanese credits on an CLV
and CAV AnimEigo disc, for reference).

Sounds plausible.

The way you describe it as stretching and squishing, I no longer think
it sounds like an interlacing artifact. There's something else at fault
there, maybe the film print got caught awkwardly during the telecine
transfer.
