Premastering describes the last step before creating a glass master for duplicating CDs or DVDs, the creation of a final premaster .

This process, often just called mastering , can turn out very differently depending on the format of the CD / DVD. The usual standard here is the red or yellow book standard.

• In the case of a CD-ROM , this process corresponds to burning a compilation of data onto a CD-R in the desired format, e.g. B. with autostart function.
• With CD-Audio, on the other hand, this process is somewhat more complex. Here in a recording studio, among other things, the final sonic fine-tuning, the track sequence, the creation of fades and pauses between the tracks and the creation of EAN and ISRCs before burning on CD-R.
• In the case of a DVD, the pre-mastering process is even more complex, as this basically represents the authoring process and takes place in an authoring studio. Here, the film and audio material, which is usually already cut to tape, is first transferred to an MPEG format during encoding . After creating a menu structure, the film is then captured on a DVD-R or DLT .

The resulting premaster, whether for CD-ROM, CD-Audio or DVD, is then used for 1: 1 transfer to the glass master. The premastering process must therefore be carried out very conscientiously, since it is the last resort for error correction before the medium is reproduced in large numbers.
