High Definition Video Formats
For HD formats, you need an appropriate third-party capture interface and hard disks
with sufficient speed and capacity. HD formats are often defined by their vertical
resolutions (number of lines), scanning method (interlaced versus progressive), and frame
or field rate. For example, 1080i60 HD video has 1080 lines per frame, uses interlaced
scanning (indicated by the i), and scans 60 fields per second.
Scanning Methods
Most HD equipment can record both progressive and interlaced video. Typically,
1080-line video is interlaced (1080i) and 720-line video is progressive (720p). Several
1080p formats exist, such as 1080p24, but there are no 720-line interlaced formats. For
more information, see “
About Interlaced Scanning ” on page 1067 and “ About
Progressive Scanning ” on page 1068.
Compressed High Definition Formats
Because of the high data rate generated by HD video cameras, most HD formats
compress the image data to fit on tape. For example:
 DVCPRO HD; also generally referred to as DV-100 (in reference to its bit-rate of 100 Mbps)
 D-9 HD, an extension of the Digital S format (Digital S is designated SMPTE D9)
 D-5 HD, an extension of the D-5 format
 HDCAM and HDCAM SR
Note: The data rates shown here are approximate. For purposes of determining hard
disk capacity for capture, carefully research the details of the format you are using.
