In a previous posting, I shared information on how it’s possible to burn Blu-ray disks using a Linux computer.
I’d just like to recap, what that posting was meant to provide instructions to do. A Blu-ray Disk essentially has 3 levels of formatting. Actually, the formatting has more than 3 levels, but the following is a simplification:
- Low-Level Formatting into blocks,
- Formatting of the blocks into a File-System,
- A special arrangement of the files, into the format required for Blu-ray players to recognize the content of the disk, as a movie and not just as data.
My posting never suggested, that Linux users wanting to burn their own movies, should use DRM or encryption of any kind.
Nevertheless, this way of doing things has become a bit contentious, and so I’d just like to mention, that I no longer recommend that users do it the way I had first written.
What I now recommend users actually do, is to use their favourite Video Editing application to export a movie as an MP4 File, or as an MTS File, or as an OGV File, or as whatever type of media file they like. And then, users can either burn this file onto a physical Blu-ray, as data, which will then have formatting levels (1) and (2) above but not (3), or that users write this file to a USB Key. That way the decision will be at the discretion of the Blu-ray player, or up to any other component of the Home Entertainment System, whether to accept this format of video for playback on the big screen.
I no longer recommend that users actually imitate the formatting layer (3) above, as if their disk was a commercial Blu-ray Movie Disk. It would be a data disk.
