Blueray picture judder

[admin_exported]

Hi Guys,

Can anyone give me an idea why my set up is not performing.

I have a Pioneer KURO 5090lx plasma

Sony 360 blueray player.

Qed HDMI cable.

Picture is fine, its just on scenes where the camera sweeps over large areas such as panning over forests or cities.

In these areas you can see a judder on the picture.

Most of the tv's motion features are switched off, I used a calibration setting i found online from a professional. (which improved picture in all areas.

Even with Smooth settings set to max on the tv the picture still judders.

SKY HD is smooth all the time. ?

For me telecine judder was down to my TV not supporting 24p.

Not sure whether this is your issue?

I changed to a TV that supported 24p and set my blu-ray to 24p and all the judder I had been seeing was not apparent.

See link below for description of telecine judder.

http://en.wikipedia.org/wiki/Telecine

However you may not be able to remove judder completely as the 24 frames per second the original material was shot at in itself can cause judder. Film directors are aware of this and do what they can to minimise its effect when considering a shot and any motion panning that it might entail.

With Sky+ HD all the encoding is done before transmission as it would have been when encoding to DVD or HD-DVD.
This issue is purely down to the source material on blu-ray is usually 24p.

The Kuro supports 24p fine.

But you get judder on some testing Blu-rays with budget players - i'd suggest your Pioneer deserves a better player for Christmas

Thats what i was thinking,

Would the New Sony 770 work better?

If you can track one of the rare beasts down, then yes, it is a slicker performer.

Your review praised its "silky smooth motion"

Everything is comparative - the Sony 'S360 was certainly a big step up for motion-handling (noticably smoother than the PS3, for example), but even the best budget players can get stressed by the most testing scenes.

I think the 5090 has most of the same options as the KRP-500a so it's worth playing with the drive modes, there's 3 options (1,2,3!), I found the one that was supposed to improve side-to-side judder actually made it worse (with football especially) but YMMV, just try all three and see which one gives the smoothest motion, I was having noticable judder with the 2001 blu-ray on the scenes where the Jupiter ship tracks slowly across the screen. I couldn't get rid of it entirely but I managed to improve it pretty well changing the drive modes. That was with a BDP-760 incidentally, TV and BDP both set to 24p.

And of course it's a generation out of date now, so you'd hope the *70 models would have moved things on a bit.

had the same issues with my pio 428xd,went into picture settings on home menu,changed picture from standard to movie then when into pro adjust and changed to advance,now no more problem.

Hi Clare,

Obviously you've seen many a great BD player. Which would you suggest for greater Motion control?

Have heard good praise for the Marantz models, but is there something slightly slimmer?

A little more control over my Panny would move my Projector viewing from very good to great.

Saving for big upgrades in 2011. 3D not necessary at present.

Big Thanks

Surely silky smooth is an absolute statement rather than comparative. I'd certainly expect no judder from that description.

Worth keeping in mind that as per the above 24fps film just has judder due to the frame rate limitation, and an expensive player set to produce 24fps won't get rid of it. I've seen it at the cinema if I look for it.

What types of scenes and objects are you seeing the judder in? And what's the effect you notice?

Hi its only noticeable on sweepings scenes usually of cities or forests, that type of thing. It makes no odds what setting the tv is on, i tried it last night,

At the time what hifi rated the sony 360 as the best budget blue ray player, with no real need to go mad on buying expensive players.

I'd say this is the inherent film judder as it tends to occur in
panning shots especially with tall straight edges. It's a nuisance as
once you notice it it can be tricky to forget about it. It tends to be more noticeable on bigger screens. Now I'm aware of it I see it at the cinema if I look for it, and could see it in a number of Due Date shots.

I honestly don't think a different player would make a difference, but as ever it's worth demoing for yourself. As encouragement a friend has a 360 with a 42" plasma and is very pleased with it.

For my projector I've found the picture mode can make a difference to how noticeable the inherent judder is, so worth experimenting. Higher birghtnes or contrast seems to make it worse for me.

To really eliminate it you need some processing that artifically adds extra frames between the originals, simulating filming at a higher frame rate, and smoothing the motion. Not sure what modes the Pioneer has for this though.

As further encouragement when I first hooked up my projector I was horrified by this effect, but with calibration have found it's now negligible.

i agree, and turning on motion processing may cause artifacts that may be more annoying..
