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. 1. Start GEAR PRO Mastering Edition.
Start Gear Software
  1. 2. Create a new DVD-9 DVD-Video Project; optionally select "Use CSS encryption".
Near GEAR Project
  1. 3. Import the VIDEO_TS content.
Video Import Selection
  1. 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).
Layber Break Detected
  1. 5. Check the Volume Properties dialog for the layer-break value (shown here in sectors).
 Volume Properties
  1. 6. To create the DDP image, select Mastering > Convert GEAR Project to DDP Image.
Convert GEAR Project to DDP Image
  1. 7. Select the name for the DDP image, and the directory to write it to.
Convert GEAR Project to DDP Image
  1. 8. Select your DDP Settings
    (SSCRST 4 for VIDEO_TS that was not flagged for CSS by the video authoring software)
    (SSCRST 3 for VIDEO_TS that is flagged for CSS by the video authoring software)

    NOTE: Make sure DDV-CMF is NOT selected when creating "SSCRST 3" or an error will occur in your DDP!
Mastering Settings
  1. 9. GEAR will create the DDP image in the directory you specified.
Creating directory with DDP Image
  1. 10. Check the properties for the IMAGE.DAT file in SideALayer0 folder
Layer Image Data Properties
  1. 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)
  1. 12. If you record the project to DVD±R DL media, place the disc back into the recorder, and pull the disc information...
Dvd Video to DDP
  1. You can see that the layer-break was set properly.
Dvd Video to DDP

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