| The NTSC format is used with the M format (see broadcast television systems), which consists of 29.97 interlaced frames of video per second. Each frame consists of 486 lines out of a total of 525 (the rest are used for sync, vertical retrace, and other data such as captioning). PAL uses 625 lines, and so has a higher picture resolution. |

| The NTSC system interlaces its scanlines, drawing odd-numbered scanlines in odd-numbered fields and even-numbered scanlines in even-numbered fields, yielding a nearly flicker-free image at its approximately 59.94 hertz (nominally 60 Hz/100.1%) refresh frequency. The refresh compares favorably to the 50 Hz refresh rate of the PAL and SECAM video formats used in Europe, where 50 Hz alternating current is the standard; flicker was more likely to be noticed when using these standards until modern PAL TV sets began using 100 Hz refresh rate to eliminate flicker. This produces a far more stable picture than native NTSC and PAL had, effectively displaying each frame twice. This did, at first, cause some motion problems, so it was not universally adopted until a few years ago. Interlacing the picture does complicate editing video, but this is true of all interlaced video formats, including PAL and SECAM. | |||||||||||||||||||||||
