DVD Master Formats

Home Email: info@the-digital-audio.co.uk

 

The type of master you supply for DVD replication will initially be determined by whether your DVDs be duplicated to DVD-R or manufactured (pressed):

 

Masters for duplication to DVD-R

For duplication to DVD-R the only useable type of master is a DVD-R (see below for additional advice). Use a single layer disc for DVD5 projects and a dual layer disc for DVD9 projects.

Please do not use re-writable discs for the final master (re-writable discs show readability problems more often than "write-once" formats do).

Write the master in 'disc at once' mode. If there is the option, ensure that masters with less than 1 GByte of data are burnt with additional 'packing' to ensure they meet the 1 GByte minimum data requirement of some players.

In order to prepare a master disc with minimum "physical" errors, please check the website of the DVD burner manufacturer to find out the exact type of media and drive firmware they recommend for use with a specific drive model. If supported by the authoring / burning  software, please run a "verify after copy " or "read after write" before you send us your master media. Don't exceed the write speed of the media.

Please full test the master to ensure that it works correctly on your target players!

Use good quality media and keep the disc free of dust and scratches.

 

Masters for manufactured DVDs

For manufactured DVDs (also known as 'glass mastered' or 'pressed' discs) you have the choice of DVD recordable or DLT masters

Depending on the size of your final project, you will need to decide if your DVD is to be a single or a dual layer DVD.

DVD5:One side, one layer. Maximum size = 4.699.979.776Bytes

DVD9:One side, but two layers. All content can be read without flipping the disc. Max. size=8.539.996.160Bytes

 

For single layer DVD productions (DVD5 or DVD10) you can send a "DVD-R", "DVD+R" or a DLT per side. Please do not use re-writable discs for the final master (re-writable discs show readability problems more often than "write-once" formats do, and under certain circumstances it could be impossible for us to detect all necessary parameters for the replication process).

In order to prepare a master disc with minimum "physical" errors, please check the website of the DVD burner manufacturer to find out the exact type of media and drive firmware they recommend for use with a specific drive model. If supported by the authoring / burning  software, please run a "verify after copy " or "read after write" before you send us your master media.

Write the master in 'disc at once' mode. If there is the option, ensure that masters with less than 1 GByte of data are burnt with additional 'packing' to ensure they meet the 1 GByte minimum data requirement of some players. 

Please full test the master to ensure that it works correctly on your target players!

Use good quality media and keep the disc free of dust and scratches.

For dual layer DVD productions (DVD9), you can burn your DVD9 content to a DVD+R DL (dual layer), or you can send two DLTs. For DVDRom or Video content that does not require copy protection like CSS, Macrovision, region code or CGMS, you just need to burn your content to a DVD+R DL, exactly the way you want it to appear on the replicated discs. The advantage is that you can check that your final master functions correctly under real conditions on a stand-alone DVD player. Our mastering system can use such "burned" DVDs as a master media directly, as long as the physical outcome of the burning process is OK. Please utilize the "verify after copy" / "read after write" feature of your burning environment to confirm the data written to DVD+R DL is fully readable again.

When preparing a master containing content to be played on DVD standalone players (“DVDVideo”), it’s mandatory that you turn ON the UDF (universal data format) file system. If you leave it OFF, it is likely that the DVDs would play on computer systems, but wouldn’t play on almost any standalone DVD player!

Regardless of the type of input media you send, please do not provide multi session content!

 

Restrictions on recordable formats, when used as a "direct" input for glass mastering:

 

DDP or CMF masters

Some authoring systems provide a function that allows the final image data to be saved in "DDP" or "CMF" format onto a hard disk, instead of writing those files onto DLT. If your authoring software provides such a function, you can use that feature to burn the control.dat, main.dat & ddpid separately for each layer onto a single DVD-R /+R. You should place the files into the root directory, or into a subfolder labelled "layer0" or "layer1". Either way is OK. If you place the files directly into root, please give the disc a name like "layer0" or "layer1", so we know which of the discs holds which content. If you prepare the master data in that way, there are no restrictions regarding copy protection, which means you can utilize CSS, Macrovision if supported by your authoring software.

 

Tape Media:

If you prefer to use DLT, please use DDP2.00, DDP2.10, CMF1.00, CMF1.10 or CMF1.20 format. The tape(s) are to be readable on DLT4000, DLT8000, DLT1 or HP VS80 drives. Please use "uncompressed" writing mode only. For dual layer titles, one DLT per layer is required.
