DVCPRO HD
A high-definition video format used to capture video digitally from FireWire-enabled
DVCPRO HD compatible decks. (Not to be confused with DVCPRO 25 or DVCPRO 50, which
are both standard-definition formats.) This format supports a number of frame sizes and
frame rates, including a 24p format that offers variable speed via a variable frame rate
technology. DVCPRO HD uses 4:2:2 color sampling for high color fidelity, and has a fixed
data rate of 12.5 MB/sec.
Note: DVCPRO HD movies do not support alpha channels.
