Need help, NIN disc doing 1080i & not 1080p

[lateralus85]

I got the NIN blu ray concert.
http://bluray.highdefdigest.com/308/...youintime.html

And i bought myself a new tv, Bravia w series 40inch. Anyway I might have changed a setting on my ps3 but for some reason this blu ray and only this blu ray that I have tested just seems to not wanting to play at 1080p. Even if I turn 720 and 1080i off it will just play at sd res and not 1080p even though its a 1080p blu ray.

Help would be grateful

Wel i don't know how the get it running on 1080p.

I olso have the same problem with my Underworld blu-ray. (it's a european version and not the unrated version)

so i to appriciate any help on that subject

I found this interesting, I went into Image optimization window on the blu ray disk where it just gives you a guide if your colour and ratio is correct. It went into 1080p mode but then when I finished the image opimization and it went back to the menu, it went back to 1080i

I found this
bad news for me

Any BD player except the PS3 should output 1080p for you with no issues, but the PS3 will only output the native resolution encoded on a disc. It will not do anything with it.

Make no mistake, even with the BD being 1080i it still has the full resolution of 1080p when de-interlaced properly and all BD players do this correctly (except the PS3 obviously).

There are some other minor things that I could talk about with regards to the BD version but I really don't think they need to be brought up. I will comment more on them when I do my review of the two versions for my publication which I am hoping to have up next week sometime when I get back from travel.

For anyone looking for a link to the website check out the end of the FAQ for BYIT, Rob put a link to my site there when he thanked me for helping with the FAQ."

I see what you are saying about the 1080p30 thing, but I think you are mistaken to say that it is the full resolution. I don't know of any technique to "de-interlace properly" that doesn't result in poor image quality. You can combine frames... this will result in jagged lines when there is motion (weaving). You can blend frames which results in blurring. Or you can upconvert to 1080p (which is what most players and tvs will do) which usually involves line doubling which again will give you visual artifacts.

For more see the "deinterlacing" wikipedia article "Artifacts will always be present in deinterlaced video"

It is certainly misleading to say 1080p on the packaging of the blu-ray when the video is actually 1080i. This is not to say I am unhappy with the release and wouldn't have bought it otherwise. It's great... I just expected more I guess. I recall Rob saying that he can not discern a difference in video quality between HD-DVD and blu-ray, so as long as when he was saying that he was referring to the 1080i blu-ray, I suppose it doesn't matter.

I am the production supervisor on all three versions of the NIN releases, and I just wanted to correct/clarify some information in the above posts.

This is correct except for the last sentence. The actual encode on the disc is 1080/30p. Because the BD spec doesn't support 1080/30p, the encode is flagged as 1080/60i, however the actual encode is 30p.

If a BD player, set to output 1080p, looks at each progressive frame and decodes appropriately, there should be no issues. You will get a 1080p stream.

If a player only looks at the flag (and not the actual content) then it could decode it as interlace.

Keep in mind that we had NO CHOICE but to flag the content as 1080/30i as 1080/30p is not supported by the spec. How this stuff is decoded by the player and displayed is entirely up to each player model. These are early times for BD, and this stuff will eventually get worked out.

But to reiterate, the actual content on the disc is a 30p encode.

I read more about it. Apparently this 1080i is run at 60fps and actually looks better than the hd dvd version which is 1080p. Im confused. Very confused.

[Getus]

well that is a bummer!

But is it the same with Underworld?

[bootman]

If your set is a true 1080p model you are watching it in 1080p anyway since in this case the set is doing the interlacing from 1080i to 1080p.
Don't sweat it. You are seeing all of the picture.

Well if i am getting the full quality then sweet by my tv clearly says 1080i when that blu ray dvd is on.

Your TV is receiving the source as 1080i, but is displaying it as 1080p.

There have always been issues with this, but I bought my whole HD setup to watch that BD and I trust Trent and crew when they say the BD looked better than the HD-DVD. NIN:BYIT is still the best looking BD that I have seen, and I watch a LOT of BDs. Some of the newer movies on BD come close, but there is nothing better than seeing footage that has been filmed with HD equipment.

NIN is great.. but there's a little too much posterization for my taste and it show it's ulgy head A LOT. I guess it's because the codec wasn't much mature when they released it...

Otherwise, it's the most grain free Show i ever saw..

NIN is 1080 x 1920 at 30 frames per second. It's 30p, fitted inside 60i (60 interlaced fields).
2 fields weaved toguether make 1 full frame. So 60i interlaced fields (60i) made up from 30 frames, when weaved together make the 30 progressive frames (30p) again.

I see what you are saying about the 1080p30 thing, but I think you are mistaken to say that it is the full resolution. I don't know of any technique to "de-interlace properly" that doesn't result in poor image quality.

Weaving 2 fields made up from one progressive frame results in getting the full resolution properly. Just look at any DVD Player software on a computer, play a movie and select force weave deinterlacing. Looks perfect, doesn't it? PAL DVDs do the 2:1 all the time: 25p movie rate inside 50i DVD.

You can combine frames... this will result in jagged lines when there is motion (weaving). You can blend frames which results in blurring. Or you can upconvert to 1080p (which is what most players and tvs will do) which usually involves line doubling which again will give you visual artifacts.

magnesium gymnasium, that is wrong as you can combine frames perfectly (see above)
Where you get artifacts is when you deinterlace film frames improperly (<-not weaving them), or when you deinterlace interlaced fields from motion actually originated as fields (like things shot with 50i/60i cameras) because each individual field does have the motion of 60 individual FRAMES (60p) but only half the vertical resolution (because a field is half a frame) so that missing resolution has to be interpolated to make up for 60 FULL FRAMES (60p).

So you can have 30p material in 60i that deinterlaces using 2 field weaving into 30p, (like the NIN concert) or actual 60i material that deinterlaces (using several differing quality interpolation techniques, depending on your hardware) into 60p. The 30p material will have each original frame flashed twice on your display to make it 60p, the 60i material will have each vertically interpolated field into a frame flashed once, making 60i -> 60p

I had the same problem with the NIN BD, until I set the HDMI options on my PS3 to allow 1080i as an option.

After that, I was able to display the HD resolution and NOT SD.
