2D/3D - same disc question

[Chrisco84]

Hi guys.
I'm new to 3D and I have a quick question.
Does either the 2D or 3D quality of a movie suffer if they are on the same blu-ray disc?
For example: I want to get Men in Black 3 3D. It comes in a single disc set with both 2D and 3D versions on the same disc or a Quad pack where the 2D and 3D versions are on seperate discs.
Would the quad pack be superior (both 2D and 3D) because they are spread over 2 discs or is having both 2D and 3D on the same disc exactly the same quality?

Depends. Some movies look the same, some look different. If the transfer's significantly different on the 3D than 2D, there is a choice to seperate discs. Usually, for converted material, it's better to go seperate discs, since one of the eyes were 'made up'.

I don't know about all cases, but on Disney's Tangled, they used clear baxkgrounds on the 3D version since you can see the depth and blurred backgrounds on the 2D version to show distance.

I am interested in this topic myself. I just enlarged the cover for the upcoming bluray release of "Dredd" and saw at the top of the "box" that it will have 2D and 3D on the same disc. Aren't the tech specs gonna suffer being that both versions will be on, I would hope, a single 50GB disc? What about bonus material, etc etc?

If the movie has both 3D and 2D on one disc, it all comes from one encode. It's called the MVC (Multi-View Codec) and it encodes both the left and right eye images for 3D. If the 2D flag's on, or the TV's switched to 2D, one of the eyes is blocked and the single eye is used to play the moive.

However, this has varying levels of quality. For example, the 3D release of Underworld: Awakening has the 3D and 2D version on one disc. Since the image is optimised for 3D, however, the 2D picture quality suffers. This is what I heard, as many people commented on this.

Does any one know whether these "3D and 2D on the same" blu-ray disc are able to be played on a standard non-3D blu-ray player? I just pre-ordered the Dredd 3D but wondered whether I can view it as I don't have a 3D blu-ray player yet.

It will play.
That's why Lionsgate doesn't even release separate 2D only versions. They'll save money if they share the disc, and it'll encourage people to future proof because they'll still be able to watch in 2D.
If the 2D couldn't play in a regular BD player, then Lionsgate has ended screwing over the majority of BD users.

Only one movie has had this problem, Underworld.

Movies such as Avatar, Coraline, ParaNorman, Step Up: Revolution(Lionsgate release, same people doing Dredd) all do this and they all have 4.5-5.0 PQ. Avatar doesn't have special features, but it's nearly 3 hours long. Coraline and ParaNorman have quite a lot of special features crammed in. Don't own Step Up, but Dredd doesn't seem like its trying to fit 4 hours of features in with it's 3D transfer.

Add "Tangled" to the list. I read the interviews with the filmmakers. They said for the 2D release to theatres they purposely blurred the background in order to show the distance when watching in 2D that they left clear in the 3D version at the theatres since you can see the distance in the 3D version with a clear background. (te original intention since it was made and filmed in 3D).

Watching the 3D version in 2D would not give you the original intent of seeing the distance while watching the 2D version in 2D would and watching the 3D version in 3D would.

Hi there:

I have a similar question to all of this, and found this thread via a search. I am not equipped yet for 3-D, but I have a couple of 3-D Blu's that also include 2-D versions. One of them, FINAL DESTINATION 5, has the 3-D and 2-D versions on two separate discs. So if I put the 3-D version in my regular Blu player, I get some sort of error message saying I don't have the proper equipment.

However, I also have the 3-D Blu of SAW 7, which has both versions on the same disc. So when I put the disc in, the 2-D version plays on my regular Blu player. My question is, though, there is no mention on the menus of the 3-D version being on the disc at all, or any way to select which version. Am I to assume that if I had a 3-D player, it would detect that automatically and just play the 3-D version automatically? What if I had a 3-D player but I wanted to watch the movie in 2-D - would there be a way to select that? Sorry if this all sounds stupid.

If you play a 3D-only disc in a 3D player you can manually select 2D on your display. That is, unless the disc is mastered in such a way that switching to 2D is specifically diasabled. Some studios do that, like Fox, I think. Others, like Paramount, don't disable switching to 2D manually, even though they don't provide a menu option for 2D playback.

I believe that some 3D discs may also start up in 2D for that reason if 2D hardware is detected. Haven't tested it, though, just speculating.

Thanks Nighteyes!
