About Standard Definition Formats

During most of the decades of color television broadcasting and video technology, the video medium was defined as 525 or 625 interlaced lines per frame at either 29.97 or 25 frames per second (fps). With the emergence of new high definition (HD) video formats, video signals meeting these older broadcast standards are now referred to as standard definition (SD) video formats.

For complete details about and specifications for standard definition formats, see “Appendix B: Video Formats” in the Final Cut Pro 7 User Manual.
