am I the only one that experiences this (moving shots in movies feel 'off')

[VoodooSamurai]

With both my digital projector, and TV, when watching blu-ray, and let's say the camera pans over a room slow, the image is sometimes a little jerky/jagged as if the set-up or bl-ray can't fully handle the movement of the camera, but it might be the disc transfer's fault. It is subtle but distracting, watching movies in the theater, this never happens. Is it something wrong with my set-up, do other people experience this? Why does it happen?

It might help knowing what your set up is.

Yes, I am using a Samsung 46" 1080p and the super blu LG HD/Combo player, with HDMI, I edited my post to explain more, that some moving shots feel slightly "jagged"

What Samsung model? There are many, you need to specify more, when posting these.
was it cheap? expensive?
And there is a forum for this too, this thread is not about "Blu-ray Movies and Releases".
Mine is like that too, a panasonic th42pz700, it was cheap!!! but it has that jaggy thing to it unfortunately, comes with the cheap price I guess.
Other than that I cannot complain.

I've noticed this in theater presentations ever since I was in third grade (1963). Think about it; the frame rate is only 24 per second, so motion is going to be more jumpy than video to start with. Several situations make this jerky motion even worse:
1. Fast pans
2. Items in background (more linear motion per elapsed frame) appear more jerky than thoe in foreground
3. Anamorphic wide-screen films (more horizontal detail is squeezed into the same negative width) makes items even more blurry in pans

Of course, it's possible you may have some display settings that further aggravate this, but its already a weakness of the film medium.

What's the refresh rate on the TV?

Isn't there 120 hz in the more expensive plasma or lcd models that deals with this problem? Or am I misunderstanding this?

It does, but imo it creates a weird effect for the movie. It seems like the movie is being sped up in order to compensate for the non-jagged motion, but the voices are still spot on. That may be just me but that is what I think

Hmm... So do you prefer the jagged effect?
I don't mind of the jaggy thing anymore, I still enjoy the movies and it's
not like a movie pans over half the time, so it's bearable.

I have seen this in theaters my entire life and I see it on every TV I have looked at.

[School]

i was at a local electronic expo they had TDK playing on a sony XBR 8 and i thought the picture looked like it could not keep up with visual movement

[SDon1969]

Panning shots always look a little bit herky-jerky to me (Samsung 1080p w/ Sony PS3), but I have always chalked it up to my TV's refresh rate being too low.

[krylonman]

The problem is, it's hard to tell if you're talking about normal judder (which is a fact of life) or some weird, uneven herky-jerky motion (which should not be there). Does it seem to be evenly spaced and uniform, or does it stutter?

Incidentally, some BDs I've seen have a weird, stuttery motion in a couple of shots, which I thought was a technical fault somewhere with the disc/my setup, but after seeing a couple of digital copies with the exact same thing at the exact same time, it seems to be either part of the movie itself or something that popped up in the mastering process. The first time I noticed this was in 'Rambo,' during the scene where the mercenaries are hiking through the jungle and pass by a cave with a group of people inside. Still can't figure out what that's about.

[kefrank]

When watching movies on 60Hz displays at home, there is judder due to 3:2 pulldown being applied to the originally 24fps (this is most noticeable on panning shots).

Even when films are shown in the theater or on displays that can do a refresh rate that is a multiple of 24, there is still some level of flicker and/or judder which is inherent in a 24 fps framerate.

Some people are more sensitive to judder and flicker than others.

Used to have this problem until I got a 120hz projector. Problem solved and it is simply marvelous.

120Hz should not be judder-free; being a multiple of 24, it should be giving you the exact same sort of (correct, normal) judder you'd get from watching it in a theater. Or do you mean frame interpolation/Motionflow? Because that's something else altogether.

[Furious911]

I noticed this too when watching Rescue Dawn on BD in 1 shot, I think its on the BD itself. Motionflow (Tureflow, etc, Ive seen other names for it) stuff looks too weird to me, it almost looks like pseudo 3D somehow but makes the movie/source look completely different then the movie to me, it looks really cool....for a bit... but not right, like not like its supposed to you know.

I decided I'll live with judder on a scene or two and not go with that Motionflow stuff.

I thought I was one of the only ones to notice this on pan shots.

I notice it on pan shots & it's annoying. I think some people are more sensitive to it & others don't even notice it.

I have a Kuro Plasma & Pioneer Elite 95FD & also a PS3.

It does it on both of them & I have it set 1080P 24fps.

Again I think it's one of the things that when you finally notice it happening you'll always see it.

There's nothing wrong with the equipment. I see it at movies & in my home theater.

Thanks for bringing it up though. At least I know some people do catch it & are annoyed by it.

Remember it is NOT the 120Hz that is doing this it is the motion enhancement settings.

Yes I'm another one who notices this judder on panning shots. It's usually objects in the background of course, and many people will tend to keep their eyes focused on whatever is in the foreground so that's probably why they aren't so aware of it. But it's simply due to the relatively low frame rate of 24 fps that film has.

Apparently the technical term for this kind of judder is "temporal sampling judder". Now you can impress your friends (or not).
