Part 1: What is 3D Blu-ray Disc<\/strong> <\/h2>\n
\n\nThe main source of high-quality 3D is via 3D Blu-ray discs. There are a growing number of titles, though these still number in the dozens, not hundreds. Worse, many of the most desirable titles are brand exclusives. So in order to get "Avatar" in 3D, you need to buy a Panasonic product. To get "How to Train Your Dragon" you need to buy a Samsung product. But all these disc work on any 3D BD player.<\/p>\n
So how does 3D on BD work? The logical assumption is that each eye's content is encoded on the disc sequentially (the frame for the left eye, then frame for the right eye), just as how it's shown on the TV. <\/p>\n
All Blu-ray 3D content is encoded at 1080p\/24. However, the two frames are stacked on top of each other. In a rare example of simple nomenclature, this is called frame packing. <\/p>\n
Because of extra data included with the two frames, the total amount of bits is slightly more than if it were a true 1080p\/48 (1080p\/24 x 2) signal. It is, as you see above, a 1,920x2,205p\/24 signal. Because of this, a theoretical full resolution 1080p\/30 3D signal would require greater bandwidth than 1080p\/60. True, the HDMI\u00a0spec<\/em>\u00a0can handle this extra bandwidth, but that doesn't mean the current generation of HDMI transmitters\/receivers can. In order to get 3D to the market in a reasonable amount of time, the choice was made to limit the frame rate to 24p (nearly all movies), rather than incur the extra development time and money on chips that could handle an increased bandwidth to handle higher 3D frame rates. So it goes.<\/p>\n<\/div>\n

<\/a><\/div>\n<\/div>\nThis isn't a major issue, though, as there is very little native 1080p\/60 content, and no 1080p\/60 3D content that you're missing out on. At least, none that would be on Blu-ray.<\/p>\n
The most important thing to understand is that because 3D from Blu-ray is actually\u00a0less<\/em>\u00a0data than 1080p\/60, you probably don't need some "3D-capable" HDMI cable to get 3D to work. It's very likely your current high-speed HDMI cable will work. All the ones I have do. Check out my article on\u00a0why all HDMI cables look and sound the same<\/span>\u00a0for more on this and why cheap HDMI cables work great.<\/p>\n
Thanks to the efficiency of the video codecs on Blu-ray, even though double the amount of data is shown from the TV, it doesn't take up double the amount of storage on the disc. More than 2D, but not double.\n<\/p>\n
Part 2: Why backup 3D Blu-ray on Mac<\/strong><\/h2>\n
Known to all, due to frequent insert-and-eject in disc drive, Blu-ray discs (including 3D Blu-rays) are easy to break. Meanwhile, Blu-ray discs are quite fragile upon lightly strike or unitentional drop onto the floor. Scratches could be easily printed onto the Blu-ray disc faces. To keep 3D Blu-ray discs safe, most people are in need of a perfect 3D Blu-ray backup solution<\/a>.<\/p>\n
\nIn addition, compared to the high price of 3D Blu-ray disc, people could get a copy of original 3D Blu-ray disc with a far lower priced blank writable Blu-ray disc, less cost for either making the copy as a backup or sending it to friend for movie sharing. <\/p>\n
There are two ways to backup and copy 3D Blu-ray movie from the original Blu-ray disc: 1:1 disc to disc 3D Blu-ray backup, and movie-only 3D Blu-ray disc backup. The former one helps copy and backup all contents (main movie, titles, movie trailers, etc.) from source 3D Blu-ray disc to blank Blu-ray disc, while the latter one saves more space by copying the main movie of source 3D Blu-ray disc to target blank Blu-ray disc. The former one is recommended because it would keep all the elements of original 3D Blu-ray disc. The latter one might get 3D movie effect lost or result in other errors during playback. But it should be noted that the former solution requires larger storage space. <\/p>\n
<\/p>\n
Part 3: Copy 3D Blu-ray Disc on Mac and Windows<\/strong><\/h2>\n
To get a copy of 3D Blu-ray disc, you have to get a 3D Blu-ray copy software program, plus source 3D Blu-ray disc, target blank writable 3D Blu-ray disc, computer with Blu-ray recorder drive, and Intenet connection for disc decrypting if neccessary. The below guide shows you how to get a copy of 3D Blu-ray disc on Mac with the help of Leawo Blu-ray Copy for Mac<\/strong><\/a>, which has both Windows and Mac versions with quite similar program interface and operation.<\/p>\n

\n<\/a><\/div>\n<\/div>\n\n\n1. Kick off Leawo Blu-ray Copy for Mac. Insert source 3D Blu-ray movie disc into the Blu-ray recorder drive. <\/div>\n<\/div>\n\n2.\tClick "Add Blu-ray\/DVD" button to import source Blu-ray disc from Blu-ray recorder drive form computer.<\/div>\n<\/div>\n\n3.\tSelect "Full Movie" option and set output disc type (BD50 or BD25) at the bottom left corner. Click the big green "Copy" button.\n<\/div>\n<\/div>\n\n4.\tSet "Copy to", "Disc Label" and "Save to" options. Click "Copy" button to start copying Blu-ray.\n<\/div>\n<\/div>\n<\/p>\n
Note<\/strong>:<\/p>\n
- \n
\n 1<\/strong>. Insert a blank writable Blu-ray disc into another Blu-ray recorder drive and then choose it as target under \"Copy to\" option. If you only get one Blu-ray recorder, choose to create \"ISO file\" first and then follow the below steps to copy created 3D Blu-ray ISO image file to Blu-ray disc.
\n 2<\/strong>. It is noted that you need to choose \"Full Movie\" mode in case of destroying 3D movie structure.<\/p>\n<\/ol>\nIf you want to copy 3D ISO image file to writable blank Blu-ray disc, check the below steps:<\/p>\n
