|
|
OK, so what is the deal with 1080p/24 on blu-ray? I'm using an LG combo player now feeding a Lumagen. Pretty much every HD DVD I can send to the Lumagen at 1080p/24. I'm running into a number of blu-ray discs that I can't coax 1080p/24 out of. I look on the packaging and I don't see 1080p/24 on those, but why would they not be? Every HD DVD was authored at that and there is not reason to author any other way especially for the format that was later to the market.
Is there really a large number of discs that are not 1080p/24?!?!?!?

A few, mainly concerts (the NIN disc comes to mind). I haven't seen any BR film that is not 1080p24, yet (maybe Colverfield?). 1080i60 should yield the same result through the VP.

Really? That's news to me Dave.
I was reading through your post thinking it was another newbie post asking what 1080p/24 was until I saw your name attached to it... so I read a bit closer. 
You already know however that film is shot 24 fps and video 30fps, so the only discs that will have the native 1080p/24 on them will be film based movies. And like you I assumed (incorrectly?) that all film based blu-ray movies would have stored the content as 1080p/24 natively so that those that want (like yourself) can extract it without doing any sort of 3:2 pulldown. Ie: a perfect extraction without any sort of conversion.
I know that some made-for-TV content is 1080i/60 (or as it's more accurate: 1080i/30) but I don't think you're talking about those.
What titles are you seeing this on Dave?

I looked through the last 30-40 or so Blu-ray discs I've bought and none of them mention 1080p/24 anywhere on the packaging on the back even though I *KNOW* that most have the data stored as 1080p/24 natively.
Have you seen any discs that do mention 1080p/24 on the package? Which ones. I haven't seen any yet.... but not like I checked every single disc I have.
Weird.
Kal

The only way I've been able to truly verify frame rates is by means of the info windows on my VP. I have not yet seen a BRD movie that isn't 1080p24.

Dave I thnik you have the Lumagens EDID set to hotplug off, i keep it on so its always locked, if its not on sometimes it switches to 1080i and you have to go into the resolution menu and switch it. maybe thats your problem? It's a theory of mine but i only have that issue once in a while, mes around with that setting and compare.

And let's all keep in mind when we talk about how the disk is authored that some of the non-content (fluff) may actually be authored differently. I ran into this on a recent BD where the Director made an oh so brief introduction and it was authored as 480P. WTH? I think this was Interview With A Vampire.

I have the PS3 setup to output everything as 1080i to the flat-panel. For some odd reason on that BD disk, something forces the output to 480P. I do not even have 480P checked as an option. And this was the only movie where something forced something else other than 1080i.

You can't UNcheck 480p as an option, can you? I can't on mine, but I haven't upgraded firmware in a while.

I'm going to check this and see if this is it.
Thanks guys. Kal, you are right. I was so used to HD DVD which as a standard on the packaging told you the resolution or the feature and the extras (which is a nice touch).
As for which discs, the first Fantastic 4 I could only get 1080i out of.
Yes, 1080i/60 from a 1080p/24 source through a VP will be the same, but a bit of why it matters to me.
I use an LG combo player for all duties. It is hooked up via HDMI to a Lumagen. Every input in the Lumagen is set up so that MEMA is my 1.78/1.85/1.66 etc memory block. MEMB is my 2.35+ memory block. The LG input has the EDID set to tell any device that the ONLY resolution it accepts is 1080p/24.
Why ONLY 1080p/24? Well, with the LG, what happens is if it can send 1080p/24 via the HDMI it will. If it cannot, it falls back to the lowest common denominator--480i. Yep, the LG will do 480i via HDMI (how f*ckin' cool, huh?). So, I put in an HD disc, it feeds the scaler 1080p/24. I put in a DVD, it feeds the scaler 480i. No messing with changing resoluions or anything.
This also keeps the set up very simple for my wife--she never has to mess with changing resolutions. The remote has 3 aspect ration buttons I've set up: Full, Wide, Scope. Full is MEMA and 1.33, Wide is MEMA, Scope is MEMB. She knows by what it looks like on the screen, which button she needs to push and if the anamorphic lens needs to slid into place. All simple and sweet.
This issue: if the player cannot output 1080p/24, it will output 480i even on an HD disc. It tries 1080i but the Lumagen is saying "no go" so it falls back to 480i. The only way to solve this is for me to set up MEMC as a copy of MEMA but with 1080i enabled and MEMD as a copy of MEMB but with 1080i enabled. Not very user friendly (hell, I don't even know what to label the remote buttons for this).
Now, it may be that since I got messed up with 1080i from F4, it may be what Athanasios said, so I'll investigate this. We watched Spiderwick Chronicals last night and it was back to 1080p/24 so all was good. But, since the F4 1080i problem, I had two discs I could not get to 1080p/24 which might be what Athanasios said.
Thanks guys.
