What is the difference between the NTSC and PAL Video standard?

SD Video that is intended for viewing on a television, whether on a tape, a DVD, or delivered via satellite or cable, needs to meet the standards of the country in which it will be viewed (NTSC countries 60hz, PAL 50hz). In North America, that is NTSC, (National Television System Committee). NTSC video is 29.97 frames per second or fps, at a size of 720x486. The NTSC standard is also used in other countries including Japan, South Korea, and most of Central and South America. Europe, China, Australia, and most other Asian countries use another standard known as PAL (Phase Alternation Line). PAL video is 25 fps, at a size of 768x576. There is a third standard called SECAM, (Sequential Couleur Avec Memoire). There is not a SECAM standard for DVD. Countries using the SECAM standard use PAL for DVDs. The internet has several sources for NTSC/PAL listings of counties and the corresponding standard. We can perform a standards conversion for an additional charge if required. Call for details.

*Most PAL players should play an NTSC DVD but most NTSC players will not play a PAL disc. There are some specialty NTSC devices that can play PAL discs but they are the exception. All computers will play both as long as the region code is not restricting playback.
