High Definition Video Formats
Final Cut Pro supports capture, editing, and output of high definition video. If you use
DVCPRO HD, you can capture, edit, and output just as you can with any other DV
format. For other high definition formats, you need an appropriate third-party capture
interface and hard disks with sufficient speed and capacity.
Scanning Methods
Most high definition formats can record both progressive and interlaced video.
 Interlaced scanning: Odd lines are drawn onscreen (called field 1), followed by the
even lines (field 2) to complete a single frame.
 Progressive scanning: Every line is scanned until a complete frame is drawn. There are
no fields.
 24psF scanning: Each frame is captured on the CCD progressively, but stored in two
interlaced fields on tape.
24psF Segmented Frame Recording
Some HD equipment uses a hybrid method to store progressively captured camera
images within an interlaced structure on tape. This format is called progressive
segmented frame (psF), and it is used for recording 24p video within the recording
conventions of an interlaced format. While this could be called1080p24, it’s technically
1080psF because each progressive frame is stored on tape as two interlaced fields that
were actually captured from the camera CCD at the same time.
