What's the purpose of 1080/24p?

[enialal]

Guys I'm wondering what's the purpose of the 24 frames per second settings? 1080/24p right? I use it but I don't know its purpose so I think I should know it. What does it do to your movie? What effects or something like that.. Please use some "newbie" terms so I could easily understand.

I think 24 frames correspond to the amount of frames shown on the theater screens so here we have a purpose of harmonization. as for P meaning Progressive, it's just that the hitherto interlaced frames shown on TV do not yield the best possible picture (since each frame is in fact half a frame). So with Progressive frames you have entire frames going one after the other.

So the bottom line is: the purpose of having 1080/24P video is because it's a major improvement over the 480 interlaced frames of TV programs.

Yeah I know already about the "p" but is there a difference watching 1080p? and 1080/24p?

You've got 1080p/60 and 1080p/24. The video resolution is the same. The frame rate is different. Be more specific, because your question is not completely clear?

I mean what effects or changes does that 24p brings to the movie?

film is 24 frames per second, so the BDs are 1080p24. Most TVs refresh much more then 24 frames a second if your TV is 60Hz, then the only difference is who brings it from 24->60, but if your TV is 120Hz then why go 24->60->120

my tv has the 120 Hz feature, and I think it is unbelievable. I am thrilled with it, but honestly, the people I show it off to are not impressed. They complain that it gives the picture more of a 'amateur' look. I have no idea what they are talking about though, because I think it is GREAT. It makes the picture much much sharper and brings a sort of 3D element to it.

maverick you are not talking about 120Hz you are talking about "motion enhancement". And your friends are probably right since you aren't actually seeing the movie as it was intended to be seen.

Ugh, no one answered the OP's question still.

24p refers to film, as has been mentioned. Since film is run at 24 frames per second, displaying it faster or slower causes unnatural movement or judder. This is an issue with many LCDs and some Plasmas in that they refresh at 60x a second. Since 24 doesn't go evenly into 60, it causes a 3:2 pulldown effect, where some frames are repeated. Many people don't notice, but there is a slight judder to the motion from this.

One thing to watch out for is just because a set ACCEPTS 24hz sources, doesn't mean it does anything special with it. My set'll accept the signal, but still has 3:2 judder.

New sets that have 120hz have the ability to properly display 24hz sources. Before rushing out and buying one though, it's good to do some research to make sure it properly displays the image.

Now I know why you don't see a difference between 720p and 1080p, look a few posts up.

I saw it, but it still doesn't explain in real-world terms what the end result is, which is some frame judder.

Also, I can see the difference between 1080p and 720p- what I believe you're referring to is the discussion on viewing distance vs. resolution, which has been discussed ad nauseum.
