Worth enabling 1080 24p for blu-ray?

[MonkeyWrench]

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!

Yeah it does say 24hz, but I don't think that's actually telling me the framerate the TV is displaying, more what signal the TV is receiving. I would have thought despite it downscaling from 1080p it would at least preserve the framerate, but I guess the resolution and framerate for BRs go hand in hand.

Sorry to hear about your PS3!

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)

No they aren't. Most NTSC film discs are 23.972 fps, the player usually does the rest to fit the frames into the 60hz signal. This is why people have always complained about NTSC dvds having judder.

Now, if you have a capable player (I don't know of any on the market) or use a PC with a screen refresh of 24/48/72hz you be be getting 24p, I've been doing it for years.

NTSC Video however is completely different, 30fps.

Nah, I can say that is 100% what the TV is displaying, not just what it is recieving. As I can get my PC to output 24Hz through the HDMI and it says the same thing, you can tell its 24Hz as the mouse cursor is jerky as hell.

I would have thought despite it downscaling from 1080p

I'm guessing this is where the problem lies, with the TV's scaling as everything else is fine.

Sorry to hear about your PS3!

Yeah, it's pretty ****ty. Went to turn it on to test this but found it won't read any disks. Don't know when it happened as I hardly ever use the thing as IMO there are no games worth playing.

Bought it from Gamestation but it is a 60GB UK version and they are like hen's teeth and my, nor any stores near me have any in. Looks like I'm in for a wait.

Well it can't be the case on mine because it says 1080p and my TV doesn't can't display 1080p, just receive it

No, NTSC film and TV/video source DVD discs are all 30fps. The 24fps film material are converted using a process called telecining/3:2-pulldown to make them 30fps - which introduces the judder. The DVD player does not do the conversion of 24fps to 30fps for NTSC films.

This is why a lot of NTSC region film buffs buy the PAL version for theatrical 24fps releases, as 25fps PAL DVDs retain the original film frames (and at higher resolution) and the PAL speedup can be easily corrected.

Nah, NTSC dvds are altered at playback, PAL discs are sped-up 4% to 25fps

Seriously, otherwise I wouldn't have been play NTSC Film discs back at 24fps for the last 5 years. Many media players will tell you the framerate of the disc, try it out for yourself, here's my NTSC copy of The Shining;



Film buffs don't buy the PAL version ever!! Video is synced to sound, so as the PAL versions of DVDs are 4% sped-up, the soundtrack also needs to be sped-up, drives us all crazy, as the timing is different and the pitch is altered, although a few modern discs do tend to have pitch correction.

I believe that Profit is correct.

CrispyXUK - I think your software can detect the frame rate of the source (film 24Hz) even though it is encoded as 30Hz, and does some processing to display it as 24Hz. I would have thought that the 'detelecine' option under 'picture settings' would need to be on though.

Which Sony telly have you got m8? The 40 model I just got the parents shows up in top left corner when its changing to 24p (same as your ? button to show what res it is). You might have to go into your PS3 options and force it to on instead of auto for it to work. As I said you just might not notice any difference, or you might notice difference in look or worse on fast moving scenes with it on compared to off and medium scenes.

24p output should be turned on. It doesn't work with NTSC DVDs (although it's technically possible - HD DVD players did it).

Also, HD DVD was still 24p. It did it in a different way behind the scenes, but it was still 24p.

Actually, it does. I encode and author (NTSC) DVDs and I do so by using Progressive flags in the MPEG2 stream. That means that only the 24 frames are stored on the disc (OK, they're stored in Fields, not Frames), and the Pulldown is actually applied by the MPEG decoder upon playback.

You are right though that there are some discs which are encoded at 29.970fps (we call this "hard telecined"). But 99% of Hollywood releases aren't done that way.

Sorry, I didn't realise that me being wrong would upset you so much.
