ADOBE PREMIERE PRO CS3 382 User Guide HD video formats are designated by their vertical resolution, scan mode, and frame or field rate (depending on the scan mode). For example, 1080i60 denotes interlaced scanning of 60 interlaced 1920 x 1080 fields per second, whereas 720p30 denotes progressive scanning of 30 noninterlaced 1280 x 720 frames per second. In both cases, the frame rate is approximately 30 frames per second. For more information on high-definition video, see www.adobe.com/go/learn_dv_primer_highdef. Programs in Adobe Creative Suite 3 Production Premium (Adobe Premiere Pro, Adobe After Effects, Adobe Soundbooth, and Adobe Encore) includes presets that are designed for working with various HD formats. Some of the most common HD video formats you may encounter include the following: DVCPRO HD Panasonic's high-definition variant of its DVCPRO format, which also includes DVCPRO25 and DVCPRO50. Whereas DVCPRO25 and DVCPRO50 support data rates of 25Mbits/s (megabits per second) and 50Mbit/s, respectively, DVCPRO HD supports a data rate of 100Mbit/s, from which it gets its other name, DVCPRO100. 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. HDV Developed jointly by several companies, HDV employs a form of MPEG-2 compression to enable highdefinition video to be encoded onto standard miniDV cassette media. H.264 Also known as MPEG-4 part 10 and AVC (Advanced Video Coding), H.264 can deliver video over a range of bitrates more efficiently than previous standards. For example, H.264 can deliver the same quality as MPEG-2 at half the data rate. H.264 is built into the Apple QuickTime 7 multimedia architecture, and it's supported by both HD-DVD and Blu-ray Disc, two newer DVD formats. Uncompressed HD High-definition video in an uncompressed format. Without compression to reduce the video's data rate, uncompressed video requires relatively fast computer processors, hard disks, and a specialized capture device. WM9 HDTV Microsoft's high-definition delivery format is among numerous formats included in the Windows Media 9 (WM9) framework. By employing an aggressive compression scheme, WM9 HDTV permits highdefinition video encoding and playback at relatively low data rates. See also Understanding and using high-definition video Options for exporting HD and HDV sequences If you have a supported high-definition capture card installed, you can export high-definition sequences to a highdefinition file format on hard disk or to tape in a high-definition device. You can also export MPEG-2 Blu-ray files, a high-definition format for authoring to Blu-ray discs; or high-definition varieties of H.264 or Windows Media files. These can be used for high-definition playback from hard disks or computer optical drives. Adobe Premiere Pro can export HDV sequences in HDV format only onto tape in a connected HDV device (Windows only). However, you can export HDV sequences to files on the hard disk in non-HDV standard- or highdefinition formats. DVCPRO HD sequences can be exported to DVCPRO HD format-either on a hard disk or on a P2 card. See also "Export to Panasonic P2 format" on page 387 April 1, 2008

ADOBE PREMIERE PRO CS3
User Guide
382
HD video formats are designated by their vertical resolution, scan mode, and frame or field rate (depending on the
scan mode). For example,
1080i60
denotes interlaced scanning of 60 interlaced 1920
x
1080 fields per second,
whereas
720p30
denotes progressive scanning of 30 noninterlaced 1280
x
720 frames per second. In both cases, the
frame rate is approximately 30 frames per second. For more information on high-definition video, see
www.adobe.com/go/learn_dv_primer_highdef
.
Programs in Adobe Creative Suite
3 Production Premium (Adobe Premiere Pro, Adobe After Effects, Adobe
Soundbooth, and Adobe Encore) includes presets that are designed for working with various HD formats. Some of
the most common HD video formats you may encounter include the following:
DVCPR
O
HD
Panasonic’s high-definition variant of its DVCPRO format, which also includes DVCPRO25 and
DVCPRO50. Whereas DVCPRO25 and DVCPRO50 support data rates of 25Mbits/s (megabits per second) and
50Mbit/s, respectively, DVCPRO
HD supports a data rate of 100Mbit/s, from which it gets its other name,
DVCPRO100
.
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.
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.
H.264
Also known as
MPEG-4 part
10
and
AVC (Advanced Video Coding)
, H.264 can deliver video over a range of
bitrates more efficiently than previous standards. For example, H.264 can deliver the same quality as MPEG-2 at
half the data rate. H.264 is built into the Apple QuickTime
7 multimedia architecture, and it’s supported by both
HD-DVD and Blu-ray Disc, two newer DVD formats.
Uncompressed HD
High-definition video in an uncompressed format. Without compression to reduce the video’s
data rate, uncompressed video requires relatively fast computer processors, hard disks, and a specialized capture
device.
WM9 HDTV
Microsoft’s high-definition delivery format is among numerous formats included in the Windows
Media
9 (WM9) framework. By employing an aggressive compression scheme, WM9 HDTV permits high-
definition video encoding and playback at relatively low data rates.

O
ptions for exporting HD and HDV sequences
If you have a supported high-definition capture card installed, you can export high-definition sequences to a high-
definition file format on hard disk or to tape in a high-definition device. You can also export MPEG-2 Blu-ray files,
a high-definition format for authoring to Blu-ray discs; or high-definition varieties of H.264 or Windows Media
files. These can be used for high-definition playback from hard disks or computer optical drives.
Adobe Premiere Pro can export HDV sequences in HDV format only onto tape in a connected HDV device
(Windows only). However, you can export HDV sequences to files on the hard disk in non-HDV standard- or high-
definition formats.
DVCPRO HD sequences can be exported to DVCPRO HD format—either on a hard disk or on a P2 card.
