One BD only displaying in 720p instead of 1080p...

[supersickie]

I'm not sure this is the right forum for a post like this, but I didn't see another that was obvious.

I have a PS3 that's connected to a 1080p Philips LCD display. The BD in question, NIN Live: Beside You in Time, is only displaying in 720p as opposed to 1080p. I've tested five other titles all of which display in 1080p as well as Gran Turismo 5: Prologue (PS3 game for the uniformed) and it is displaying in 1080p (one of the few titles that is legitimately capable of doing so) as well.

I just watched the BD is question yesterday and everything looked great. I only bring this up because I was able to notice something amiss by just glancing at the display this evening; I could readily tell something wasn't quite right as I've just become accustomed to viewing BD in 1080p. I guess the obvious thing is I just have a bad BD, but it's a really hard pill for me to swallow seeing as it worked great just yesterday.

So, I'm just curious to know if someone has a similar experience or can think of something I may have missed. For the record, I've checked, disconnected, and reconnected all HDMI and power connections from both the display and PS3. I've even gone so far as to do a video/audio reset on the PS3 in hopes that would fix the issue. Alas, nothing has done the trick.

Thanks in advance.

That's certainly true, but I don't believe it's the issue in this case...

According to what the person who produced the disc has said, it was recorded at 1080p30 and encoded at 1080/60i - since there is no 1080p30 option in the Blu-ra specifications. I don't have a PS3 but maybe you need to change the output settings of the PS3 (to 60i or interlaced) to get it to output this title at it's full 60i?

Also 60i is normal (and better than 24p) for concerts as it gives it the 'live' look that say 24p doesn't have - though since Nine inch nails was recorded at 30p instead of 60i, you won't get as much of the 'live' look that a 60i interlaced originated concert would have.

Also, 60i is more pixels/data per second than 24p.

Thanks for the response. I'm not so concerned as to how it looks as I am that it was displaying in 1080p before but now will only display the main concert in either 720p or 1080i if I allow it to do so.

Another tidbit that I just discovered is that if I go into the video optimization section on the BD in question the display suddenly changes to 1080p. I go through optimization - which really doesn't do anything other than check to make sure you're aspect ratio isn't out of whack - and it goes back to 720p upon returning to the main feature. Highly suspicious, but it is hitting 1080p at some point. All in all, I'm just extremely annoyed by this more than anything.

Any other insight would be greatly appreciated. Thanks very much.

EDIT: Apologies for all of this. It seems my memory is mistaken as there are numerous reader reviews that appear to be experiencing the exact same issue concerning 720p/1080i on the main concert and 1080p elsewhere on the disc. Thanks.

It could be the menu is in 1080p24, but the main content is encoded at 1080/60i - from the original 1080p30 since there is no 1080p30 option on Blu-ray.

now will only display the main concert in either 720p or 1080i if I allow it to do so.

In my opinion, I think it's probably best to to output 1080i, since that is how it's encoded on the disc (1080p30 encoded as 1080/60i). Your TV will convert it to progressive if the PS3 doesn't.

the main menu. Both the Winter and Summer tour portions of the disc come in at 1080i and I
can't figure out why.<

The reason for this is that the NIN concert is shot in 1080/30 fps progressive video. However the
Blu-ray spec supports only 1080i/60, so in order to be 'spec legal' the video is encoded as a
1080i/60 stream. Most players will render this correctly as a 30 fps progressive, but the player will
report it as a 1080i.

Which is better 1080p30 or 1080/60i? Are you also saying that the Blu-ray spec doesn't allow for 1080p30?

I'd prefer a concert that was shot at 1080/60i (ie. shot in interlaced mode instead of 1080p30) as it has much more of the live look to it than 1080p30 (or 1080p24), so in my view, for concerts, I think 60i is better. It has twice as many motion samples as 30p, but they both have exactly the same number of pixels per second. With 30p all 1920x1080 pixels captured each 30th of a second. With 1080/60i half of the lines are captured in 1/60th of a second and the next half in the next 1/60th of a second. The TV or Blu-ray player will up-convert & de-interlace it to 1080p60. Neither would be as good as a 1080p60 originated concert if one was shot using it (there are cameras capable of it, but I don't know of any concert shot using it).

Some people might disagree and say that 1080p30 is better than 1080/60i, but personally for concerts (and the same for sports or other live events too), 1080/60i is much better for capturing motion than 1080p30 since it captures at twice the number of samples per second (even though in total the number of pixels captured per second is the same as 1080p30).

Are you also saying that the Blu-ray spec doesn't allow for 1080p30?

Yes, there is no 1080p30 option in the Blu-ray spec
http://www.blu-raydisc.com/Assets/Do...2955-15269.pdf

See page 17 of the spec. linked above - 1080p30 has to be encoded in a 1080/60i stream, like the producer of NiN said in the user review section of the Blu-ray review page for NiN.

So that maximum for 1080p is 30 frames per second? For my setup which would be best 1080p/24 or 1080p/60 for movies? Also should I move Judder Reduction to 0 if I used the 1080p/24 output on my Oppo?

Thanks Systemlord

I was talking about concerts etc. there ie. things that benefit most from the live look of 60i (just like sports do). And as said, 1080p30 can only be encoded on Blu-ray if it's encoded as 1080/60i (like NiN).

Films are different. Probably more than 99.999% of films are shot at 24fps. They are (nearly always) encoded at 24fps (or 23.976) on the disc. Whether you like the 24p look for films or whether you want to set judder reduction or motion-plus style interpolation on is personal preference. Though I'm sure most on this site would probably recommend that 24p films are output by the player at 24p if your TV is capable of accepting that input and displaying it at a 24fps multiple, and that they'd recommend not to use motion-plus interpolation if you want to see the film correctly/'as the director intended', but it's down to personal preference.

So if you want to watch the film normally, I'd recommend outputting at 1080p24 (assuming your TV is capable of receiving it) and turning judder reduction to 0 (though I don't have the Oppo, but I'd think that's right).
