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)
