24hz Vs 60hz?

[TVENOMG]

I have a 1080p lcd 40inch and a ps3 im wondering which setting would be better for viewing my blu-ray movies on the ps3 24htz or switch it off and it shows as 60 htz.Its my understanding that the higher the hertz the smoother the picture.

you want to have your ps3 setting to whatever your tv is capable of. unless you own a samsung 71 or 81 series, sony xbr4 or xbr 5, or the sharp d92, then you need it on 60hz.

So Sharp has a TV capable of viewing at 24p?? I thought only the Sony XBR4/5 and Panny Plasmas were capable of true 24p viewing?

I have to tell you, IMO, if your TV is capable of 24p, I would not watch my BD's on any other setting....I recently exposed myself to the newest Blu-ray Promo disc at best buy on their 40" sony xbr4 and I am not happy any longer with my new 52" Sharp LCD....so I am currently replacing it with the 46" XBR4.

The model is a samsung le40m86bd 40inch 1080p lcd with 24fps display capability

It means it will accept a 24Hz signal, not display it at 24Hz.
It will display at 120Hz.

If your TV is a 120Hz model, set your PS3 to forced 24fps output for sure.

What iF the set accepts it, but is a 60Hz model? Do you still force it?

It is capable of 60Hz - it will display a 75Hz signal from a PC, but only 60Hz is recommended.

You'll want to set your player to 60Hz output, not 24Hz.

How can a TV accept 24 Hz but then not display it correctly? That doesn't make much sense. I thought a TV was either 24 Hz compatible or not?! My 71f accepts and indicates in the info it is correctly displaying 24 Hz via PS3.

I'm sorry you're incorrect.

Several HDTV's can accept a 24Hz signal, but only have 60Hz display.

They perform the 3:2 pulldown themselves instead of letting the player do it.

It's neither correct nor incorrect, but the 71F may perform 3:2 pulldown in the set and bump it up twice to 120Hz.

Chances are most people won't notice the difference anyway.

It means the pulldown conversion is being done in the TV instead of the transport. Pick which one does it better. TVs can massage the picture a lot.

Well I definitely notice a difference with 24Hz enabled on the PS3. Everyone seems to complain that 3:2 pulldown is a pain and noticeable because of judder. I don't notice any judder with the 4671f and the info indicates 24 Hz when a device is outputting is 24 Hz, and 60 Hz otherwise. Oh well, looks good either way

I myself first had it on 1080p/24 on my Blu-Ray player, but I've always read that 60hz is better because the more the herts, the better the refresh time in-between images. Every time I enable it on my TV, it always goes from 1080p/60 hz to 1080p/24 hz. Can someone please tell me which is better?

Is it true or not that 60 is better than 24?

Is it true or not that 60 is better than 24?

Depends... Is your tv capable of displaying 24 frames per second properly? First of all your tv needs to be a multiple of 24, such as 48hz (mostly front projectors) 72hz, 96hz, 120hz, 240hz (72 and 96 are for some plasmas while 120 and 240 are some lcds).

However, just because it is a multiple of 24 does not mean it will accurately display 24fps. For example some Panasonic plasmas from last year (maybe this year too, not sure) create flicker with 24, even though they had a 48hz option I believe (might have been 72 or 96). And some lcds that are 120hz or 240hz don't either. Some take the 24fps, do a 3:2 pulldown, and then repeat that twice.

To display 24fps accurately it needs to do an even pulldown. For 120hz it's 5:5 pulldown, for 48hz it's a 2:2 pulldown, and so on.

60hz tvs (which is more usual) cannot display 24fps accurately and do a 3:2 pulldown regardless if you set your blu-ray player to 24hz.

So 24 is "better" than 60hz because film is recorded at 24fps so it's more faithful to the source, and removes that uneven motion caused by a 3:2 pulldown. However most people are use to 3:2 pulldown and don't notice it. We've been watching movies at home with a 3:2 pulldown since vhs.

Now if your wondering why not a 24hz display, it's because people notice flickering far too easly at 24hz. Cinemas show movies at 48hz because most people can't see flicker at 48hz. As for the Panasonics showing flicker at 72hz or 96hz, that's most likely an error in the processing or something.

Please check this sticky https://forum.blu-ray.com/display-th...rame-rate.html to see if your tv is listed. It's right at the top.

I have a Sony XBR4 and it does accept 24p. I set both my Sony S570 and the S350 BD player before it to 24p output. As the XBR4 did accept 24p video, I'm pretty sure the XBR5 did as well.

Are tv shows filmed at 24hz or 60hz?

[fairchild]

I think if a TV show isn't recorded at 24 fps, then it would be at 30 fps. I am pretty sure TV shows are recorded in both 24p and 30p. Big production shows like say Lost would be 24p. Some stuff is starting to be recorded at 60 fps but it's more rare. Per Wikipedia, here's a quick explanation:

The 24p frame rate is also a noninterlaced format, and is now widely adopted by those planning on transferring a video signal to film. Film and video makers use 24p even if their productions are not going to be transferred to film, simply because of the on-screen "look" of the (low) frame rate which matches native film. When transferred to NTSC television, the rate is effectively slowed to 23.976 frame/s, and when transferred to PAL or SECAM it is sped up to 25 frame/s. 35 mm movie cameras use a standard exposure rate of 24 frames per second, though many cameras offer rates of 23.976 frame/s for NTSC television and 25 frame/s for PAL/SECAM. The 24 frame/s rate became the de facto standard for sound motion pictures in the mid-1920s.

30p, or 30-frame progressive, is a noninterlaced format and produces video at 30 frames per second. Progressive (noninterlaced) scanning mimics a film camera's frame-by-frame image capture. The effects of inter-frame judder are less noticeable than 24p yet retains a cinematic-like appearance. Shooting Video in 30p mode gives no interlace artifacts but can introduce judder on image movement and on some camera pans. The widescreen film process Todd-AO used this frame rate in 1954–1956.

25p is a video format that runs twenty-five progressive frames per second. This frame rate derives from the PAL television standard of 50i (or 50 interlaced fields per second). Film and Television companies use this rate in 50 Hz regions for direct compatibility with television field and frame rates. Conversion for 60 Hz countries is enabled by slowing down the media to 24p then converted to 60 Hz systems using pulldown. While 25p captures half the temporal resolution or motion that normal 50i PAL registers, it yields a higher vertical spacial resolution per frame. Like 24p, 25p is often used to achieve "cine"-look, albeit with virtually the same motion artifacts. It is also better suited to progressive-scan output (e.g., on LCD displays, computer monitors and projectors) because the interlacing is absent.

50p and 60p is a progressive format used in high-end HDTV systems. While it is not technically part of the ATSC or DVB broadcast standards, it is rapidly gaining ground in the areas of set-top boxes and video recordings.

Film is recorded at 24p, and you always want to use the native frame rate if possible. Don't get confused by the hype, 120/240Hrz modes only butcher film.

Not all are shot on film. Both 24Hz and 60Hz are used for TV shows and more.
ie:
24, 25, 30, 50 and 60Hz.
