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:

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
HDCAM on the Wikipedia website.
