BD-RB and Blu-Ray 3D

[jangai]

Sorry if already mentioned:
Does the current version of BD RB can shrink a 50GB blu-ray 3D to 25GB?

[HWK]

No, BD-Rebuilder can't compress 3D Blu-Ray.

Right now there's no freeware encoding solution that I know of for 3D blu-ray (MVC). My guess is that the X264 folks will attack it eventually -- but I'm not sure the demand is high enough yet.

Hi!Does the current version of BD RB can shrink a 50GB blu-ray 3D to 25GB?Yes, it can, if like the original "Coraline" release (and, I believe, 2008/2009 "Journey to the Center of the Earth"), the Blu-ray disc uses the older anaglyph 3D methodology (requires "blue/red" glasses)...

Great thank you, but of course I thought of the current BD 3D and near future : I am 66 ! :) :) :)

[setarip_old]

@jangai I am 66 !And I don't even remember 66 (The near future is tomorrow morning) ;>}

I'm fairly certain that with the skilled programmers of multiAVCHD, MakeMKV, X264, AnyDVD, and DVDFab, it won't be long after a significant number of 3D releases hit the market that solutions will appear...

Cool ! Happy to see former guys like me enjoy these wonderful technologies that comfort us a bit finding the daily ravages of a sad declining civilization ... :p

Yes I hope so, as said JDobbs, I think X264 team will not remain long without an interest in new formats required by Blu-Ray 3D ...
We must remember first public show of these solutions were... early 2010

Im confused, if it's not possible how come I come across various 3D releases in x264 format? Aren't those shrinked?


Also, wouldnt i be able to encode the x264 to BD-25?

Right now there's no freeware encoding solution that I know of for 3D blu-ray (MVC). My guess is that the X264 folks will attack it eventually -- but I'm not sure the demand is high enough yet.We have a few possible sponsors:

1) A certain application streaming company wants to be able to stream 3D software.

2) Blu-ray authoring companies would like to be able to author 3D Blu-rays.

But the problem with this is that nobody wants to pay the tens of thousands of dollars to develop it without being sure that it'll be useful. And nobody in the industry is confident that 3D will be any more than a bygone gimmick in 3-5 years, just like the last 4 times that 3D was "big".

The two images required for 3D blu-ray discs are stored and then automatically detected by player / tv to give the 3D effect. However it is possible to encode both of these images seperately and then present them as an image as side-by-side (SBS) or over-and-under. The SBS method is the way that SKY make their broadcasts in the UK - on my tv when you watch Sky you change the tv to 3D, and then you choose the way the images are shown - the tv then does the rest.

There is a piece of software (3DBDBuster) which re-encodes the two blu-ray images and then muxes them together to give one of the above formats - I think these are the files you have seen (unless they are Sky recordings). I have tried a couple and they work very well but they aren't Full HD like the blu-ray discs, as the maximum resolution (1920x1080) has to contain both images- but if they are good enough for Sky to broadcast, then they are obvious okay for most people.

Ok one more question, what if the content was already encoded to x264 and I wanted to encode it back to BD25, does this mean I would still need to use the 3DBDBuster software for the 2nd encoding to convert it to BD25?

Assuming that you're not investing in expensive blu-ray mastering software, I think that the route to go would be multiavc, as that could create a 25GB avchd disc (with menus if required). However, there is no non-commercial way of creating a 'proper' 3D blu-ray disc - I'm merely talking about taking the SBS mkv file and authoring it. If you are going to use a pc to play the file you could just burn the mkv to the disc, as it's the tv that does all of the 3D processing and combining. Also, many of the new blu ray players can play mkvs straight off the disc or the tvs can play the files of a usb device (plug or HDD) - my Samsung certainly has that ability as well as picking the file up via the network off the pc.

depends what x264 profile was used. I think the latest BDbuster 3.5 has bluray encoding options added
