Blu-ray dubbing refers to transferring video content to BD media on a hard disk drive. Dubbing includes both the “mood” of moving the original content from a DVD recorder or computer by erasing it, as well as duplicating the content. This article will introduce the methods of BD dubbing that can be performed at home.
What is dubbing?
Dubbing refers to the process of adding additional audio tracks, such as music and sound effects, to a pre-recorded film or video. The term originated from the combination of the words “duplicate,” meaning to make a copy, and “dub,” which refers to the process of recording sound after the visuals have been completed. In English-speaking countries, dubbing typically refers to the process of re-recording dialogue in a different language, while in Japan, the term has a broader meaning.
In Japanese digital television broadcasting, measures were put in place in April 2004 to prevent copyright infringement. This included the implementation of a copy control function for all digital broadcast programs. Under this control, viewers can only make one copy of the content they have recorded and if they choose to transfer it to a recording medium like DVD-R or BD-R, the original data is erased, and the video content is moved. While copy control is effective for copyright protection, there have been concerns that these restrictions are too strict. As a result, in July 2008, a new measure called “Dubbing 10” was introduced to address these concerns. With Dubbing 10, the content can be transferred to an external recording medium with up to 10 copies, including one move.
Therefore, in Japan, the term “dubbing” refers to both the act of making copies and moving video content when it comes to handling optical disc media. If you are interested in ブルーレイリッピング, please read this article.
What is the difference between Blu-ray (Blu-ray) and DVD
The difference between Blu-ray and DVD lies in their storage capacity and quality. Blu-ray discs are the next generation of DVDs, offering approximately 10 times the storage capacity. A single-sided, dual-layer Blu-ray disc can hold up to 50GB of data, while a standard single-layer DVD can only hold 4.7GB.
Furthermore, Blu-ray content has around 6 times the pixel resolution of DVDs, resulting in a higher quality visual experience. The audio data of Blu-ray is also superior. These features make Blu-ray a popular choice when it comes to storing and watching high-definition content.
When it comes to dubbing or copying content, Blu-ray recorders have several advantages. First, there is no need to select an initialization mode as required with DVD discs. When a new Blu-ray disc is inserted into a Blu-ray recorder, it automatically starts the initialization process to prepare the disc for dubbing. Additionally, Blu-ray discs can be repeatedly initialized, allowing for data erasure and adding new content.
Another advantage of using Blu-ray recorders is that the dubbed discs can be played on other devices without the need for finalization. In contrast, DVDs require a finalization process to be playable on devices other than the one used for dubbing. This lack of finalization requirement allows for easier content addition on Blu-ray discs.
Moreover, the dubbed Blu-ray discs have the same copy protection (AACS) as commercially available discs. This means they can be played on any AACS-compatible Blu-ray recorder or Blu-ray drive, although there may be some exceptions due to variations in equipment. On the other hand, dubbed DVDs use a different copy protection system called CPRM, which requires the use of CPRM-compatible devices for playback.
Finally, there are two recording formats for Blu-ray discs, BDAV and BDMV, which have higher compatibility compared to DVD formats. BDAV is used for recording digital broadcasts, while BDMV is used for recording commercial or self-made content. Their versatility is higher than the DVD-VR format, and there are more Blu-ray players that support playback of BDAV recordings compared to DVD players.
In conclusion, Blu-ray offers a greater storage capacity and higher quality compared to DVD. When it comes to dubbing content, Blu-ray recorders have advantages such as simplified initialization, no finalization requirement, and compatibility with existing copy protection systems.
