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.

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

What's the refresh rate on the TV?

[ghebert]

I notice this even at the movie theaters...I think it is just a side effect of the frame rate not being real time.

Actually, I think the opposite is true for me in the theater -- with the frame rate at only 24 fps, camera pans cause a blurring effect across stationary objects, such as text on saloon signs, fence posts, etc. IMAX cured this problem by increasing the frame rate to 30 fps for theatrical presentation. Home video has a higher frame rate than theatrical presentation (with "fields" replacing "frames") so I haven't had the same exact problems per se on home video (though the blurring still exists on camera pans, its just not as striking or strobing as in the theater).

Your problem might be the refresh rate of your TV -- I've got a piece of crap Westinghouse HDTV 1080p set and "the tank" (Sony BDP-S300) as my blu source, and I've never had the problem you're experiencing.

I thought the frame rate was still usually only 24fps on IMAX? Do you know of any IMAX films that are higher frame rates than 24fps? Or are you talking about how the projector shutter works (by flashing each frame at least twice)?

Well, depends on who you talk to, but this page states the frame rate is 48fps:

Another says "three times faster":

I don't know for sure. Maybe I sure ask in the Insiders thread.

I know for 3D they'd be sending twice as many frames per second (1 for each eye).

The "3 times faster" isn't 3 times as many full frames per second, I think that it's that it moves the film through the projector in a different way (different direction) than normal projectors so you get a higher resolution and that it uses more film than you would in a normal projector. Or something like that But I don't think it's saying that the number of frames shot per second is higher than 24fps for a normal IMAX film.

[s2mikey]

I hear what ya'll are saying. Its likely the 24fps issue that some have touched on. Some TVs have a feature to help with this. My Pioneer KURO has a 24fps refresh feature that runs 24fps content as 72Hz. 24 x 3. It significantly reduces this affect although you never quite get rid of it totally.

Still, the Pio KURO designers were thinking way ahead about this issue and have had it on TVs several generations back where as hardly any other TV mfgs do. LCDs are often lousy with this problem.

Hail to the KURO!

I beleive IMAX currently uses 24fps for their 2D movies. But they are planning to introduce "IMAX HD" which will increase the framerate to 48fps which from test screenings people have said it gives a smoother image. I find it weird they call it "IMAX HD" even though 70mm film has a way higher resolution then 1080p. And IMAX is also planning to replace if some IMAX locations havn't already replaced their 70mm 3D projectors with a pair of 2K Digital projectors.

I experienced that when I watched the The Dark Knight (maybe especially in the IMAX sequences). Probably due to the 24fps frame rate (watching on 100/120Hz 24fps capable HDTV with the Motion Plus feature turned Off, and 24fps output enabled on a Samsung Player).

It might be more noticeable on certain types of sequences - like fast camera movement (perhaps the higher resolution imagery makes the slow 24fps frame rate more noticeable).

Yeah i really noticed it when i was watching that movie too.

[Realist01]

I have a samsung 40" 1080p 120hz and what you might want to do, if you have it, is turn the auto motion to off. The TV will run at 120hz regardless if you have the auto motion on. The problem is that, Blu-Ray or DVD only run at 24fps. If you have your auto motion on, it's going to look as if they are in a slow fast forward.

[reece]

It seems like these types of issues are inevitable...the fact is, our TV's/digital projectors are not film projectors, and when you cross these types of technology its just never going to be perfect...similar to how grain can be more pronounced/distracting on blu...
