What is DVD / CD duplication vs. DVD / CD replication?
Duplication is ideal for low volume whereas Replication is most suited for high volume runs of 1000 units and more
- DVD / CD duplication is similar to "burning" DVD – Rs / CD-Rs on a computer with a CD / DVD recorder. You must have a DVD recorder drive and software to duplicate DVDs. At Bright Images, your DVDs will go through a top-of-the-line auto loading system process and the format used is called a DVD-R. PLEASE NOTE: DVD-Rs play in most but not all manufactured DVD players. We can accept DVD-R/RW, DVD+R/RW and DVD+R DL discs as masters, but we prefer to output to DVD-R because it is the most compatible with standalone DVD players and DVD-ROM drives. DVD / CD Duplication is used for Low volume orders up to 1000 units.
- DVD / CD replication is a manufacturing process of creating a glass master, is created from the customer's supplied media and used to press the digital information to make the DVD/CD replicas. DVD replicated discs can play in virtually all players and in all PCs with a DVD-ROM drive and player software.
What is DVD-5, and DVD-9 replication?
- DVD 5 replication is single-sided single layer. It is referred to as 4.7GB media which holds 4.37 computer GB (1 kilobyte = 1024 bytes) which is 120 minutes of audio and video. DVD-R/RW and DVD+R/RW support this format.
- DVD 9 replication is similar to DVD 5 replication in that all printing is done on one side and all the data is on the other side. However, the difference is that a DVD 9 is single-sided dual layer. It is referred to as 8.54 GB media which holds about 7.95 computer GB (or roughly 220 minutes of audio and video). It has been the most commonly used format for Hollywood movies.
What is DVD authoring?
- For DVDs, authoring involves the assembling of assets (video, film, stills, menus, audio) into a format compliant with the DVD specification. The DVD specification is a series of guidelines created by the DVD Forum. The DVD forum is a collection of hardware manufacturers, software firms, and content providers. The specification is a set of rigorous standards and guidelines created to help ensure compatibility and unity with all DVD players and DVD content. Although the specification has clear guidelines, there are still authoring programs and DVD players that may not follow all of the specifications to the letter. This can result in DVDs that may not play or may not play the way the author intended.
- Videotapes and QuickTime/AVI files are not ready as is to use in DVDs. Their files sizes are large, 101GB for an hour of uncompressed or 11GB for DV, and cannot fit on a 4.8 GB DVD-5 or a 8.5 GB DVD-9. To make these large files small enough to fit on a DVD, they must be encoded or compressed. The proper format to compress for DVD is the Mpeg2 format – the required standard for Standard Definition (SD) DVDs. This process can be accomplished utilizing either hardware or software encoding.
What's CD-R? CD-RW?
- CD-R is short for "CD-Recordable". Recordable CDs are WORM (Write Once, Read Multiple) media that work just like standard CDs. The advantage of CD-R over other types of optical media is that you can use the discs with a standard CD player. The disadvantage is that you can't reuse a disc.
- A related technology called CD-Rewritable (CD-RW) allows you to erase discs and reuse them, but the CD-RW media doesn't work in all players. CD-Rewritable drives are able to write both CD-R and CD-RW discs.
All CD recorders can read CDs and CD-ROMs, just like a standard CD-ROM drive.
Are CD-Rs identical to normal CDs?
- CD-ROMs and music CDs you commonly find in stores are pressed from a glass mold. CD-Rs are burned with a laser. They may look different (often green, gold, or blue instead of silver), they're less tolerant of extreme temperatures and sunlight, and they're more susceptible to physical damage. Whether CD-Rs or pressed CDs last longer is difficult to answer.
- While they're not physically identical, they work just the same. Some CD players and CD-ROM drives aren't as good at reading CD-R and CD-RW discs as they are at reading pressed CDs, but by and large they work just fine.
How much can CD-Rs and CDs hold?
- Commonly available blanks hold either 74 or 80 minutes of music, which works out to 650MB and 700MB of data, respectively.
- Short for Short for DVD-Recordable, a recordable DVD format similar to CD-R. A DVD-R can only record data once and then the data becomes permanent on the disc. The disc can not be recorded onto a second time.
