Alright, i've been trying to research it more, but having a hard time coming up with what exactly is cinema smooth, what is it doing for the picture, and how is it doing it by what method. And lastly do other plasmas have similar features to cinema smooth? which i believe only samsung have such a feature called this.

Is it worth having, worth choosing samsung just because of this feature...


thanks.

what exactly is cinema smooth

It's a sales pitch to try and make you buy a crappy Samsung instead of the better brand.

Cinema smooth allows the panel to refresh at 96hz. This allows for the normal 3:2 pulldown process to be avoided on blu-ray movies. The result of this is that 'panning' scenes will be slightly smoother. Its a subtle effect, but many are pleased with it. Others don't really care.

It should be noted we as viewers are very used to 3:2 pulldown (it is used when watching DVDs).

So bottom line: cinema smooth = slightly smoother motion on certain scenes, when watching blu-ray movies and applying the correct settings on your Blu-ray player and TV.

Any refresh rate multiple of 24 allows the TV to achieve this. It does not matter what rate is used (common refresh rates are 48, 72, 96, and 120), they are all capable of preserving the cadence of film and avoiding 3:2 pulldown.

Also these refresh rates are best paired with TVs that have inheriently good motion resolution, and luckily the 2009 plasmas are nearing CRT levels here. This is the more important measure, imo. Slightly smoother motion with too much TV-induced blur kills any positive effects.

To answer the other part of your question, there are other panels that have this feature, but they go by different names. It is generally a step-up feature, meaning it is not found on entry level models, which makes sense as it is not a must-have feature.

It is called '24p direct in' on the panasonic G/V/Z series, and 'PureCinema Advanced' mode on all pioneer kuros.

Is it worth it to step up? Sure, unless you are on a budget, in which case it is best to focus on the basic PQ attributes first.

The reason its hard to say if it is worth it is because reactions vary. You may not notice much until you watch a DVD with 3:2 pulldown right after watching a blu-ray, and then you may see the 'hitch' of 3:2 pulldown in certain scenes.

cinema smooth
anyone knows if it's only display 4 times the same frame (at 96hz)
or does it displays interpolated frames (1 original + 3 interpolated)

is "Film Mode" on LG's the same feature? or something different

I still have not seen the benifit of 72hz on my elite kuro no matter what settings are on. Its quite frustrating actually

i found this info on lg website for the PS60 series...
5:5 24P Real Cinema 120HZ
So is that basically the same thing as Cinema Smooth?

also think i read that film mode is a 3:2 pulldown, so does 3:2 produce judder?

panasonics v10 series also has a similiar feature called smooth cinema making 24p films flow without judder and provide smooth transitions with motion and provide a film like picture that feature is gonna be on the uk version don't no if the us one will have that same feature.

Samsung Cinema Smooth is apparently "4:4 pulldown" (96 Hz).

AFAIK, none of these modes utilize LCD-style interframe generation (AMP).

If I am correct, much of the complaining about earlier Panasonic film modes centered around the 48 Hz playback (2:2 pulldown), which apparently Panasonic figured would work for them like it works in film projection.

Does this only affect blu ray movies or would HD content over cable, for instance, be "enhanced" also?

Thanks

Any source with 24p would benefit, I believe.

Since Plasma TVs (like the Samsung PN58B550 have a 600hz refresh rate, and 24 divides evenly into 600 (25 times), does Cinema Smooth have any effect at all?
If it does, then I've misunderstood the science and the explanations in this thread.

600Hz refers to their sub-field drive, not their refresh rate.

As mentioned in the post above, the 600hz specification is just marketing hype. It has nothing to do with the refresh rate which is not a factor in plasma displays. Cinema Smooth has value because it introduces a frame rate of 96 fps which 24 divides into.

Yeah, the issue with the 48Hz refresh on the Panasonics is that the vast majority of people will notice annoying flickering of the picture. For most people, the flicker problem is not an issue with 72Hz or 96Hz refresh rates. Unfortunately, on Panasonics the 96Hz refresh rate is only available on the V10 and Z1 lines.

My samsung plasma TV D8000 series (2011) accepts and displays 1080p/24 HDMI input. What purpose does "Cinema Smooth" have in this scenario? Can't a plasma display 24 progressive frames per second and is not contrained to 30/60/120, etc?

The native refresh rate of any N. American plasma is 60 times per second as that is our electric grid frequency. It doesn't pair too well with motion picture film which is typically shot at 24 frames per second. The Cinema Smooth function alters the refresh rate of the television from 60 Hz to 96 Hz so that it can accept the 24 Hz input without any weird gymnastics. For instance, at 60 Hz, Frame 1 has to be shown three times with Frame 2 being subsequently shown twice. That's obviously an "uneven" display of the original film but the only way you can make the math work. Change the TV to 96 Hz and you show Frame 1 four times followed by Frame 2 four times. In theory, a more even display.

Television makers have chosen to increase the refresh rate rather than slow it to 24 or 48 Hz because slowing the refresh could cause a discernible flickering of the screen for viewers. Hope that helps.

Yes very helpful. The 'info' window in the tV is misleading when it reports resolution and refresh rate. The resolution it reports is what it is displaying (480, 720, 1080, etc) but the refresh rate it's apparently reporting is the source framerate, not what is actually being displayed. One can understand the confusion.

Currently running 24P from bluray, hitting info says 1080p / 24hz. So if I'm running Cinema Smooth "on" the display should actually be running at 96hz? Is there any way to see the "true" refresh rate with any given signal, not just the input signal?
