122 Appendix High Definition Video Fundamentals

720p60

This format is smaller than 1920 x 1080, but the smaller image dimensions allow the

frame rate to be doubled. Sports events and other rapid-movement imagery are usually

broadcast in this format.

Pros

• Yields the highest frame rate possible with the DVCPRO HD format.

• Individual still frames in this format have no motion artifacting (such as flickering

lines) due to the progressive scanning.

• Captures and displays quick action and fast camera moves smoothly.

• NTSC compatibility because of the 59.94 fps video rate

Cons

• Smaller image size than 1920 x 1080 (though still higher resolution than standard

definition video)

720p30

720p30 is a particularly flexible format because it is compatible with standard definition

NTSC video (because it has a matching frame rate of 29.97 fps) as well as streaming and

downloadable video (because it is progressively scanned). Because of the progressive

scanning, 720p30 is also useful when you need a video format that can output

high-quality still frames.

Pros

• Compatible with both standard definition NTSC (29.97 fps) and computer graphics

(progressive scan)

Cons

• Smaller image size than 1920 x 1080 (though still higher resolution than standard

definition video)
