因3D碟內有兩個同樣檔案一齊，一個純2D(十幾至二十幾GB)另一個是3D所需景深來(十GB 左右), 所以2D版隻碟淨 ...
謝謝師兄解答

BLU RAY黎講, 西片都還好, 港產片就真係要三思...
個隻什麼竊聽3我就真係唔識欣賞.好彩係平BD.HEEHEE....

我把bd碟放落電腦bd盤已睇到個容量
發覺同一套戲，2d碟容量會多高3d碟
通常D特別收錄…都在2D碟，所以size大D,
我覺得
按Wiki資料所得，一般Blu-ray會用到以下codecs
H.262/MPEG-2 Part 2
H.264/MPEG-4 AVC
VC-1
現時一般會多用AVC和VC-1。
VC-1: Designed to offer very high image quality with excellent compression efficiency
H.264: Designed to meet a variety of industry needs with many profiles and levels, allowing for varying compression, quality and CPU usage levels, where the lowest level is for portable devices, designed with low CPU usage in mind, while the high levels are designed with very high quality and compression efficiency in mind
而 Blu-ray 3D 會用另一種codec叫MVC，所需容量約為普通Blu-ray的1.5倍。
The Blu-ray 3D specification calls for encoding 3D video using the "Stereo High" profile defined by Multiview Video Coding (MVC), an extension to the ITU-T H.264 Advanced Video Coding (AVC) codec currently implemented by all Blu-ray Disc players. MPEG4-MVC compresses both left and right eye views with a typical 50% overhead compared to equivalent 2D content, and can provide full 1080p resolution backward compatibility with current 2D Blu-ray Disc players.
其實Blu-ray 2D和3D用不同codecs來encode/decode，所以容量必然有分別，有些廠商會因應3D大容量而提高壓縮比，所以有可能出現3D版容量少於2D版 (其實一般2D會多些features或其他東西)，結果質素和效果會有些少分別。
如果用3D轉2D功能，一般player會凈係播左邊畫面，同純2D比較，應該會有分別。
以老變4為例，3D版有iMax 3D，有部分戲出16:9，3D轉2D後，容量細啲；2D版，2.35:1，容量高啲，理論上畫質高啲，但冇iMax，睇起上嚟菲林感少啲；所以，最後都係睇製作。

應該係2D有埋製作，所以容量高啲。
