A question regarding 1080/60p and 1080/24p

[mainman]

I just cant figure it out.

I am reading in forums, that some people wish the PS3 could output 1080/24p.

Why do they want this? I mean isnt 1080/60p better?

Or do they mean something else? Like 1080p/24hz?
Is 1080p/24hz the best quality?

Could someone explain this to me, or provide a link or something?

And the following are all in the BD spec right?
1080/60p and 1080/24, 1080p/24hz and 1080p/60 hz.

Thanks.

24 frame per second is the film frame rate and most (all?) film sourced Bluray discs are encoded at that frame rate.

60 frames per second is the video display rate on most TVs.

Since 60/24 is not an integer number, there is a motion artifact associate with going from 24 to 60 frames per second. Since they usually show one frame twice and the next frame 3 times (and repeat).

People would prefer to have 24 fps output to avoid this artifact. The 24 can be multiplied to 48, 96 or even 120 without adding such artifacts.

In simple terms, a 24p output into a monitor or projector that can display it, gives smoother motion for 99.99% of movies.

(There's a couple films and some TV programming made in true 30fps, and some made for Europe and Australia programming made in true 25fps, and of course 50i/60i videotape, which would use the 60Hz framerate. But the rest is all 24 fps film) (Not counting silent films, of course)

Does this include my Optoma H-78 (aka H-79) 720p pj?
It accepts the 1080p 60 and 24p signals from the Sony Player...were it would only accept 1080i from the Philips player via hdmi.

I am still waiting on the H-81 1080p version to get a few bugs worked out before jumping in....and until then I will use the H-78.

Its very odd that most 1080 displays will not accept the 24p signal ...but my 720p pj does

One problem of the PS3 BD playback bothers me is the *blink* feel of actions. The fast moving objects looks like *jumping* on screen. My setting on PS3 was 24p, I will change it to 60p to see if things got better.

My TV does support both 24p and 60p.

If this experience you're talking about happens when watching movies, that's because the 24fps judder effect during slow panning. The camera captures 24 frames in one second. Our eyes can observe a faster rate than that, which is at the Imax rate of 60fps. It'll always be there and can't be eliminated.

Does the PS3 do this as well with BD movies? Or does it show 24fps?

I believe PS3 out puts at 1080p60. I have not heard any thing different. The XRB LCD do accept 1080p24 and 1080p60. I get my 52" on the 4th with the sony player. Hand delievered to me by a sony rep. The makes me a happy purple aardvark. I would tell the story about the purple aardvark but it might get me in trouble.

Purple-ray!

Is there a difference in displaying VS outputting?

Say PLAYER outputs at 24fps, however TV displays at 60fps (=60Hz), so the TV converts 24fps -> 60fps internally, anyway resulting in that "motion artifact". Therefore, if you want to see "motion artifact"-free (genuine 24fps) video you need a TV that can run at 24fps (=24Hz)

I believe the ps3 does support 1080p @ 24 fps. Mine offers off, automatic or on as far as settings go. I'd assume, Off would mean it would send out the signal at 60fps then.

All 7th gen & newer Pioneers support 1080p/24hz/fps input. Some can also "extract" this from DVD.

hi,well i have a question,i have a sony xbr2 lcd tv and a sony bdp-s1 blu-ray player and when i have it set on 1080i the picture looks much clearer,more detail,just a better picture than when set on 1080p and if i set it in auto,it plays at 1080i/60 and if i set it on direct it says unsupported signal,check your device output,so its like i can't get 1080p/24 but yet both the blu ray player and the tv both support 1080p/24 and everything is connected with hdmi,confused?

ps3 can put out 1080/24
