Hmm, be careful what you wish for - you might get it. When I said that, 21 posts ago, on page 3 number 10 of this thread, I didn't really expect the consequence to be that absolutely nobody would have anything to say about my lovingly compiled pre- and post-calibration gamma values for all my modern televisions ...... hey ho. :?

RE: 24p smooth film yes or no?

A lot of it goes over my head ,a lot of u guys have been into this stuff for years ,going from the gt50 to zt60 I don't really have much to compare things to.some people have real problems out there and I'm fretting over sharpness and contrast lol

Son of SJ - that table doesnt really say a lot mate.

I know for a fact its possible to get a good 2.19 / 2.2 gamma average out of the LX5090, colour temperature means nothing really - you are aiming for 6500k but its never 100% bang on.

Its interesting that your LG set is calibrated to 2.4 and the others to 2.2?   Do you knwo why - thats not an indepth question but at leats I am showing interest Wink

Just posted on that thread, now I've had chance to re-read them - they make much more sense now, having seen the process first hand!

Hello Interested ellisdj (who needs Steve Davis, the Interesting snooker player, anyway!) surely the post-calibration temperatures are worth checking, no? Steve got them all as close to 6500K as he could.

No, I don't know why the LG is calibrated to a gamma of 2.4 whereas the other televisions are closer to 2.2 - I was more than happy to leave Steve to do what he thought was best!

RE: 24p smooth film yes or no?

Do you know why and what that is a measure of?

6500k is white and its a measure of how accurate your white is .... Pretty sure that's correct

You're assuming that effort is directly proportionate to reward. Unfortunately, life doesn't work that way.

It probably doesn't help, but I read and ruminated on your post, Son_of_SJ, even though I didn't respond directly.

I know this is an old thread,

I know this is an old thread, but if anyone is still interested, I just got a ZT65b, and when setting it up using Avatar 3D, I prefer the 24p smooth set to medium or high, . I tried turning it off and it was very juddery, also I have the 3D refresh rate set to auto as the 120HZ mode strangely seems to introduce more flicker. If I turn on the intelligent frame creation to mid and turn 24p smooth film to off, the picture doesn't really have that much noticeable judder, but I just set the 24p smooth film to mid or high and have intelligent frame creation set to mid, this seems to really smooth out the picture and make it crisper. I can't understand why everyone advises to turn these features off, the judder is very noticeable with all these features turned off. The panasonic zt65b is by no means perfect in every area. So I believe taking advantage of processing can make the picture better. By the way I applied the calibrated 3D settings from the sound and vision website, the sound and vision recommended calibration settings have much better blacks than the built in cinema THX 3D, the blacks are darker and the colours pop more although I'm not sure if the darker blacks are obscuring some shadow detail, but it looks great . But I'm not an expert and can't afford a calibrator to come around and set it up so it's the best I can do .

For anyone else who picks up on this thread.

Personally I would never use anything like IFC or 24p Smooth.

The main reason being most BDs these days are created at 23.98fps so you're not getting the full 24 frames anyway.

This (stupid idea in my mind) was to compremise between the different frame rates between PAL and NTSC. The PAL 1080 will be 1080/50i 1080/25p = 50 frames interlaced and 25 progressive.

the NTSC 1080 picture is 1080/60i or 1080/30p = 60 Interlaced and 30 progressive.

Don't ask my why they can't make a standardised 1920 x 1080 resolution picture 24fps world wide if the feature has be shot primeraly in 24fps but I think it's mostly to do with TV content. with NTSC SD at 480i and PAL at 576i thse creat a different frame rate and with PAL having more picture available in the first place means less frames to put it on screen.

You'd have to look up on Wikipedia for a more indepth explination but that is basically why you get judder no matter what you do. There are some BDs out there that are 24p and they will look best with any fancy TV setting set to off so you watch it native but I couldn't tell you which ones. Don't even trust the packaging. I would say some of the early BDs are 24p

Your problem here is in the refresh rate you have set - Leave it on Auto and you wont get juddering in any 3D film.

I am sure avatar is 100hz not 120hz hence the juddering.

If you get the TV calibrated when you can you will see that 24fps smooth adds artifacts and false edges etc - its not needed

I get almost perfet picture and movement in 3D that is equal to that of 2D for the most part (tech of the panel aside)

Calibrated 3D on your TV will blow your mind!!
