You can reap benefits from shooting and editing in high-definition formats even if you output to standard definition.
For example, the quality of high-definition clips remains high when you zoom into them or pan across them in the
context of standard-definition projects.
HD video formats are designated by their vertical pixel dimensions, scan mode, and frame or field rate (depending on
the scan mode). For example, 1080i60 denotes interlaced scanning of 60 interlaced 1920x1080 fields per second,
whereas 720p30 denotes progressive scanning of 30 noninterlaced 1280x720 frames per second. In both cases, the
frame rate is approximately 30 frames per second.
useful even for standard-definition delivery, because the extra pixels give you a lot of room for synthetic (fake) camera
work, such as zooms and pans in post-production.
Trish and Chris Meyer provide tips for planning and delivering high-definition and widescreen work in articles on the

Adobe digital video applications include presets that are designed for working with various high-definition formats.
Some of the most common high-definition video formats you may encounter include the following:
High-definition video recording formats
AVCHD (Advanced Video Codec High Definition)
High-definition format based on an MPEG-4 AVC video codec for
file-based (tapeless) cameras. AVCHD was introduced by Sony and Panasonic. For more information about AVCHD,
see the article
on the Wikipedia website.
DVCPRO HD or DVCPRO100
Panasonic’s high-definition variant of its DVCPRO format, which also includes
DVCPRO25 and DVCPRO50. Whereas DVCPRO25 and DVCPRO50 support data rates of 25 Mbits/s (megabits per
second) and 50 Mbit/s, respectively, DVCPRO HD supports a data rate of 100 Mbit/s, from which it gets its other
name, DVCPRO100. DVCPRO HD footage can be captured to Panasonic P2 media. For more information about
HDCAM
Sony’s high-definition version of its Digital Betacam format. A variant called HDCAM SR uses a tape with a
higher particle density to record video with greater color sampling and at higher bit rates. However, HDCAM SR is
supported by decks only, and not camcorders. For more information about HDCAM and HDCAM SR, see the article
XDCAM HD and XDCAM EX
High-definition formats developed by Sony for file-based (tapeless) cameras. For more
on the Wikipedia website.
HDV
Developed jointly by several companies, HDV employs a form of MPEG-2 compression to enable high-
definition video to be encoded onto standard miniDV cassette media. For more information about HDV, see the
article
High-definition codecs
H.264
An MPEG-4-based codec that supports encoding in high definition for Blu-ray Disc media, and the FLV |F4V
v210
An uncompressed codec that supports encoding in high definition at 10-bit 4:2:2 in component YCbCr.
Supported by the Uncompressed Microsoft AVI format.
UYVY
A codec that supports encoding in high definition in YUV 4:2:2. Supported by the Uncompressed Microsoft
AVI format.
MPEG2
A codec that supports encoding in high-definition for Blu-ray Disc. File extensions: .m2v, .wav (audio only).
