Monitor Display Resolutions
1430
You can use lower resolutions when your work does not require very high image quality (for
example, in offline work, or in CD-ROM or Web authoring projects), and higher resolutions
when you need excellent image quality. You can also mix different resolutions within the same
project as long as those resolutions are compatible with one another. (see “Mixing Resolutions”
on page 1444).
Avid editing applications also support the capture and storage of video that is not processed by a
data compression scheme:
• Uncompressed video (1:1) is available as standard definition (conforming to the ITU-R 601
standard) or as high definition (conforming to the ITU-R 292M standard). The image quality
of uncompressed video is very high, but uncompressed files require very large amounts of
drive space. For more information, see “Support for Uncompressed HD Media” on
page 1443.
• DV (digital video) is a compressed media format. SMPTE standards specify how to take 601
video and convert it to a compressed format. When capturing through a 1394 connection,
your Avid editing application records DV media in its native format, and does not compress
it further.
Monitor Display Resolutions
The display resolution for the monitors in your Avid editing application varies depending on the
video format, as described in the following table.
