DVD interlacing issue? - Blu-ray Forum

CptGreedle · 09-21-2007, 02:47 PM

I have been watching the entire 2 seasons of Ghost in the Shell: Stand Alone Complex on DVD on my PS3 with my Sony Bravia 46". Although I did not notice it in the first season, in the second season I have started to notice an interlacing effect on all motion in the scenes. To me it just gets worse and worse, and even though my wife sees it, she says it doesn't bother her. But I can't help but see it every time someone is running, or moving fast, or when the Tachikomas do just about anything at all.
The DVDs are DTS high quality discs, so the image should be better than the standard DVD release. (At least the sound is).
Do DVDs run in interlaced? Do I have something set wrong? Is it the DVD? (although it's been on all 3 from the 2nd season, i'll have to check the first season again).
Anyone else see this?

So you are watching it upscaled to 1080i on your ps3? if so, have you tried setting it to 720p instead?

CptGreedle · 09-21-2007, 03:15 PM

Well I have a 1080p tv.. i don't know why it would only go to 1080i.. and how would I change it to 720p without affecting the entire system?

That depends on your player. May not be possible. Check the manual for both your TV and player.

CptGreedle · 09-21-2007, 03:52 PM

As I said before, it is a PS3. It shows everything in 1080p. I have it set up to use 1080p, so I assumed it should show a DVD that way. But what I saw looked way too much like interlacing.

Try another movie? Maybe your highly trained 1080p sensitive eyes are playing tricks. Rub some salt in them, and watch a few hours of Oprah on SD TV. That might help.

No really, you got me on that one.

Papi4baby · 09-21-2007, 04:00 PM

Well eliminate errors and components first. If you have a regular DVD player try it on that. Also dont do the up-scaling, let the feature show at what it was produced at 480P. Have you try the season one again since discovering this issue? It might be a bad DVD, not just yours but maybe a bad encode. good luck.

CptGreedle · 09-21-2007, 04:06 PM

Could it be the original DVD? Does anyone know if DVDs are interlaced? Or could it be something else to do with this exact title?
I'll see if I can find the same thing on any other DVD, but I noticed it most on animations so far.

Papi4baby · 09-21-2007, 04:07 PM

It could also be your tv, most tv now days have some sort of digital enhancement that actually affect the picture coming into it. See if there's something like it and turn it off.

What does an "interlacing effect" look like?

as far as i know, DVD's are encoded at 480i. so maybe that is what you are seeing

there are things that are recorded interlaced (videotaped things), and movies derive from progressive film frames but be recorded as interlaced masters, sometimes the flags for them are wrong, sometimes progressive frames are intermixed with interlaced video, etc etc, 24fps, 25fps, 30fps, 50i, 60i a potpurri of rates, etc etc

In any case I think the PS3 has on BD/DVD Settings/Cinema Conversion Automatic and Video choices. Could try that.

WickyWoo · 09-22-2007, 04:59 AM

The vast majority of titles are converted to progressive scan anyway at the encoding stage because it makes things so much easier

MouseRider · 09-22-2007, 08:13 AM

Unfortunately, just because it has DTS sound doesn't make it a high-quality DVD. I've got plenty of DVDs from Asia that have DTS and mileage varies from disc to disc.

You might want to try switching your PS3's Cinema mode to Video so it doesn't try to do 3:2 pulldown if what you're describing as "interlacing effect" is jerking/line blinking and jagged diagonal lines.

If what you're seeing is moire patterns or shimmering areas in scenes where there are lots of fine lines, such as in scenes where there is a wide shot of skyscrapers with lots of lines for windows, what you might be seeing is artifacts caused by the scaling itself, you might find that playing it in 480p would solve that.

Except for anime. They do try to convert to progressive, but the result is rather hit or miss because of mixed cadences in the source. You usually get a mix of progressive and interlaced throughout the disc. GitS SAC is rather unique for anime because they were given 1080P24 masters, and so they should in theory be able to make fully progressive DVDs. Theory doesn't mean practice however, so I can easily understand it if they still didn't get it right - it's very possible that the authoring house's equipment didn't support 1080p24, and so they'd either have to use 1080i or 480i as the source.

I definitely notice combing with my PS3 when watching some material like Trek:ds9. That was shot on film, yet edited on video. My oppo player with the faroudja chip plays the same scenes without a hitch.

CptGreedle · 10-16-2007, 06:00 PM

Thanks for the input. I know it is a long time since I responded to these but I just watched some more last night and it is still there.
To clarify the effect... it looks like a bunch of horizontal (possibly diagonal) lines whenever there is "fast" movement. It looks like this effect is replacing what should be a motion blur. It drives me crazy and my wife thinks I am too picky. I bought a freakin 1080p system for a reason, of course I'm picky!

Either way, I will try playing with it and try out a DVD tonight (Shaun of the Dead) and report anything if I see it.
It really annoys me though. It is in every major "fast" movement from running, cars chases, to hand and arm movements. I just hope that some day, the entire series comes out on Blu-ray.
