    Worth enabling 1080 24p for blu-ray?

    Just wondering if its really worth enabling? As i'm sure it would be different for most films like Ratatouille or live-action.

    You mean within the PS3? As long as your TV supports it I don't see why you wouldn't want it enabled.

      Yes, i did mean the ps3. My new tele does indeed support it. What are the benefits of having it enabled, if i've read elsewhere correctly it allows you to view the film as it was originally intended for the cinema or something like that.

        Yeah. As I understand it - it means the refresh will exactly match (Or be an exact multiple of) the refresh rate that the film was captured in.

        You may notice when a camera pans in a film (Or as the credits roll) there's a slight judder? That's because of the refresh rates being different - set it to 24fps on a supported TV and that should be eliminated.

        That's my understanding anyway.

          Yes, the films are shown at 24 frames a second in the USA, which is the correct running speed for them. So the 24 option will show the film exactly as it was in the cinema in America.

          In the UK they are shown at 25 frames a second to match with the frequency of the voltage (which is why the run time of a UK standard DVD is slightly shorter than the run time of an American DVD).

            It's not going to work unless your TV supports 24p anyway.

              But all dvds and video and telly sources in USA are always altered anyway with pulldown so most people are used to pulldown on any source as NTSC is nearly 30frames native (29. something) and had pulldown so all the signals whether PAL or ntsc have gone and had pulldown to convert them. You also have different formats for telly and film to help not having to resort to certain types of pulldown. It used to be really bad but they use some very good pulldown techniques nowadays. Basically if you been watching films on dvd for years your not going to notice out.

              24p is what you would see in the cinema. You will either notice a difference or you wont with it fixed at 24p or using pulldown to convert the images. Theirs pros and cons for both with pulldown you get a slight judder on medium fast pans but with 24p you get judder on very fast action scenes. 24p can look different from pulldown. At moment 24p is the B word for selling tellys so you can watch your HD films the way they where meant to be, myself I find it a non issue. You also have to take into account not all film transfers where made with 24p.

              Try it anyway you will either like and notice it or you wont. It wont damage anything forcing it if you dont have a compatible tv it will just go black. I just got a new telly for parents and it has it built in but they dont like it so we have it off. Myself I dont think its such a big deal as Ive tested it a few times for awhile. If it was I would have traded mine in for one with amount of films I go thru.

              To help some helpfull quickstarts

                Note the 24p support is intended for Blu-Rays, which are encoded as 24p anyway. I'm not even sure it works on DVD's.

                  Na its BR compatible films only m8. Its like HDDVD I think if I remember right that was 30p not 24p.

                  Their is sets out their and projectors what will do 24p x 3 for an even smoother image

                    Ahhh so it's only compatible films? I have a 24p enabled TV and the setting enabled on my PS3, but Casino Royale still juddered when panning. Is this information usually on the case?

                      NTSC DVD Film Discs can be played back in 24/48/72hz and have been ever since DVD first came out with the appropriate player, this is one of the initial reasons for the rise of the HCPC.

                        What TV? It may except 24p, doesn't mean it'll display it in a multiple of 24hz.

                          It's an LG 32LC56.

                          Yeah it doesn't specify whether it will just except or display 24p.

                            It would display '24p' or should I say '24Hz'. There is an easy way to tell though, when the movie is playing, press 'OK' on your remote and it will display the 'Hz' so you will know for sure.

                            My TV the LG60PF95, can do 24Hz so I use that for Blu-Ray from my PS3 and it works fine. Although this is all moot really as I don't see any difference between running it at 24Hz and 60Hz, no tearing or stuttering on either, when panning or rolling credits.

                            The only problem is that the LG32LC56 is a '768p' TV.

                            The problem your having is that unless you were in 1080p mode it won't be in 24Hz, which you can't do. Ask far as I can see you can't output in 1080i 24Hz, although I can't be sure as when I went to test I found my PS3 was broken!

                              I suppose i should have made it more clearer. I recently bought a Sony Bravia 40" 1080p tele which has 24p.
