Chapter 2 Video Formats and Timecode 25
I
Frame Rate
The frame rate of your video determines how quickly frames are recorded and played
back. The higher the number of frames per second (fps), the less noticeably the image
flickers on screen. There are several common frame rates in use:
 24 fps: Film, certain high definition formats, and certain standard definition formats
use this frame rate. This may also be 23.98 fps for compatibility with NTSC video.
 25 fps: Standard definition PAL
 29.97 fps: Standard definition NTSC
 59.94 fps: 720p high definition video frame rate. This can also be 60 fps.
For more information, see Volume IV, Appendix B, “Frame Rate and Timecode.”
Scanning Method
Video frames are composed of individual lines, scanned from the top of the screen to
the bottom. Lines may be scanned progressively (one line at a time), or interlaced
(every other line during one scan, and then the alternate lines on a subsequent scan).
Standard definition video uses interlaced scanning, while high definition formats may
use either interlaced or progressive scanning. For more information, see Volume IV,
Appendix A, Video Formats.”
About Timecode
Timecode is a signal recorded with your video that uniquely identifies each frame on
tape. When you capture video or audio in Final Cut Pro, you also capture the timecode
signal, which is displayed in Final Cut Pro when you play back your clips. Timecode
allows you to recapture your footage from tape and always get the same frames.
Final Cut Pro uses SMPTE timecode (developed by the Society of Motion Picture and
Television Engineers) which is represented in hours, minutes, seconds, and frames,
using the following format:
In Final Cut Pro, timecode is used for synchronization between video and audio clip
items, project interchange (such as Edit Decision Lists), and recapturing clips from tape.
When you play clips, Final Cut Pro displays the media file timecode. Timecode also
allows you to navigate through your sequences, and see how long your edit is.
For more information about timecode, see Volume II, Chapter 25, Working With Timecode.”
