Standard Definition Versus High Definition Video Formats
Motion is extremely flexible and can work with both highly compressed and uncompressed
video.
Standard Definition Video
Despite having differing frame sizes, NTSC and PAL standard definition video share certain
characteristics.
• Both signals are interlaced, although the field order depends on the video capture
device used.
• Both signals have a 4:3 aspect ratio, but a 16:9 aspect ratio can be accommodated
either anamorphically or by using letterboxing.
• Both use nonsquare pixels to display the picture.
Analog standard definition formats include S-VHS, Hi-8, and Beta SP.
