would like explanation on why some movies have constant pulsating effect

[STARSCREAM]

Ok, so this has been bugging the heck out of me and I can't find an answer to it. I'd like for someone knowledgeable to explain to me why some movies have constant pulsating effect to it?

For instance, The Wizard Of Oz blu-ray has this constant what appears to be brightness fluctuations or something that is especially noticeable on backgrounds and things were it gets bright then dim etc. It it horribly noticeable and distracting at the first on the sepia toned scenes but you can also see it throughout the movie.

Another blu-ray is Ghostbusters. It does the same thing throughout and it very distracting as well. I've noticed newer movies don't do it though there are some with scenes that do it occasionally but not throughout the entire movie like the ones I've mentioned. Is it due to the type of film used, lighting, color timing,????? It is very distracting to me.

It could be a setting on your tv.

Those are old movies, so I am assuming they were remastered/cleaned up. Some scenes may appear brighter/darker than others. I have experienced this with The Godfather.

Nope, or all movies would do it. Also, I have tried them on 3 different displays (2 tv's and a projector) and they still do it.

That's not what I'm saying though. I'm talking about in the exact same scene the pic will have a pulsating effect to it where it's like it gets darker then brighter then darker then lighter.

I have Ghostbusters and have never noticed that. Not sure what would cause it.

Well unless it's some problem with the hardware chain (auto level brightness suffering hysteresis? faulty connection? etc) rapid brightness variations in film are sometimes caused from uneven development on the film or due to improper storage or age(fading) in different sections of the windings on the reel. Film is being displayed at 24 photos a second or 90 feet of film per minute, so if for some reason above adjacent frames have different densities it would look as a brightness flicker or constant changing unevenness as the frames or uneven sections pass at the 24fps rate

I've occasionally noticed a rapid flickering effect on an interior scene where there is a bright light just off screen. One example I can think of is in a particular shot in 'A Clockwork Orange' where there is very harsh strip-lighting on an interior set (I think it's in the Korova Milk Bar). I've seen this effect on both DVDs and Blu-rays.

Could that be the effect that you're talking about?

I've never noticed such a thing on my copy of Ghostbusters.

Same, here. I've played it on a 60GB PS3 to a Vizio 50" plasma, and a Sony BDP-S350 to a Samsung T240HD.

I have most certainly noticed it on Wizard of Oz. The first thing that came to mind is it has to be because of the age of film. As far a Ghostbusters, I have yet to watch the Blu-ray but it could be suffering from the same thing. Maybe that film wasn't protected well.

Are you describing "flicker" - random variation in intensity from frame to frame, or by "pulsating" do you mean a slower predictable variation.

I have not noticed anything unusual about "Ghostbusters" - I haven't watched "Wizard" on blu yet. On the other hand, I have watched enough movies over many years that I am no longer sensitive to flicker and other minor variations in the image.

Well, if i understood right, i've noticed this on a few scenes of Planet earth (cant remember which scene actually) and in some other blu that i cant remember either -fish memory-.
If just my english knowledge would let me explain myself... but it doesnt

What kind of displays have you used? I know you stated 2 hdtvs and 1 projector. Do they have a "dynamic" setting that is engaged?

[dougotte]

Sounds like flickering due to uneven aging of the film. I haven't seen the two mentioned here, but I've seen it on many other films, both on DVD and Blu-Ray. A few examples off the top of my head:
The Third Man
The Lady from Shanghai
Double Indemnity

I have also noticed this "pulsating" "flickering" in older movies like wizard of oz, gone with the wind in a few scenes (mostly darker). I have also noticed it in recent films like Planet Earth, and I do belive it is just the film and not your set as I have 3+ sets and notice it on every single one.

[Hammie]

I've never noticed this issue. Therefore, it does not exist and you are wrong.

Oh so i'm not crazy, or at least i'm not alone in that matter

[vsidhu]

if it's in all films try using a different connection, like component, and see if that resolves the issue
