What is the difference between PAL and NTSC video format?
When mastering a DVD and ordering DVD replication it is important to recognize which area of the world your DVDs will be played in so that your master is produced in the correct format.
PAL – Phase Alternating Line
‘PAL’ refers to the television broadcasting standard which is used by most of Europe, amongst other countries.
NTSC – National Television Standards Committee
‘NTSC’ is used for broadcasting in United States, Canada, Japan and some parts of Central and South America.
Converting PAL to NTSC
If you plan on distributing your DVD to America then your master DVD will need to be converted to PAL format prior to replication or duplication. This will ensure that your DVD works on DVD players in America. You should also be aware that most computer based DVD players will play both PAL and NTSC DVD’s so although your DVD may work on a computer it won’t necessarily run on a DVD player if it is not in the correct format.
DVD replication and duplication supplier’s, such as wewow, can convert your DVD to NTSC or PAL ready for the replication/duplication of your DVDs.

PAL format is the kind of video standard that is used in many European Countries. NTSC is used in the United States and many other Countries like Japan for example. PAL has nothing to do with the actual videocassette…VHS is a world standard. PAL has to do with the output Hz of the local electric company therefore affecting the speed at which your TV will be refreshed/drawing on the screen. If you are in doubt, call a local TV repair store; they will give you the correct option to order.
