How To Create a DDP image of a double-layer DVD-Video with automatic layer-break detection

With GEAR PRO Mastering Edition, it's easy to create a DDP image of a double-layer DVD-Video title. This allows you to see that the layer-break set in the video authoring software is detected and properly used by GEAR PRO Mastering Edition. You can be sure that when the DDP is sent off to a mastering/replication facility it will have the layer-break set correctly.

To create a DDP image of a double-layer DVD-Video title

    1. Start GEAR PRO Mastering Edition.

    2. Create a new DVD-9 DVD-Video Project; optionally select "Use CSS encryption".

    3. Import the VIDEO_TS content.

    4. During the VIDEO_TS import, GEAR will detect the layer-break value that was set in the DVD-Video authoring software (shown here in ECC blocks).

    5. Check the Volume Properties dialog for the layer-break value (shown here in sectors).

    9. GEAR will create the DDP image in the directory you specified.

    10. Check the properties for the IMAGE.DAT file in SideALayer0 folder
    File:08-Layer0IMAGEDATProperties.JPG
    11. SideALayer0 IMAGE.DAT is 4,248,928,256 bytes
    4,248,928,256 bytes ÷ 2,048 bytes/sector = 2,074,672 sectors (layer-break value in sectors)
    2,074,672 sectors ÷ 16 ECC sector blocks = 129,667 ECC blocks (layer-break value in ECC blocks)


You now have a DDP image with a properly set layer-break value that was automatically detected by GEAR.
