CHOOSING A WORKFLOW
The HD Express supports a range of SD and HD
workflows. For uncompressed HD or SD, all
DVCPro formats and Apple ProRes, the
HD Express provides sequence and capture presets
for all supported format/frame rate/codec
combinations. Other codecs require that you make
your own custom sequence settings. Refer to the
following sections for further information
regarding each workflow. Also see “Video
encoding and CPU performance during capture”
on page 36.
Uncompressed HD/SD
The HD Express supports 8-bit and 10-bit
uncompressed HD or SD capture and playback in
all supported HD and SD formats. Choose the
sequence preset and capture preset that
corresponds with the format you need to capture,
edit and play back.
☛
Capture and playback of uncompressed HD
requires a high-performance RAID array.
Apple ProRes 422
The HD Express supports Apple ProRes 422
capture and playback. When capturing ProRes,
Final Cut Pro requires an Intel-based multi-
processor Mac, and four or more processor cores
are recommended. For ProRes operation, be sure
to choose the
HD Express Apple ProRes 422
presets
(for the sequence, capturing and playback) that
correspond with the video format and frame rate
you are working with. If your computer
experiences performance issues during capture or
playback, you may need a faster computer, a faster
hard drive, or a capture drive with less disk
fragmentation.
DVCPro25 / DVCPro50 / DVCProHD
The HD Express provides capture and playback of
DVCPro25, DVCPro50 or DVCProHD. Choose the
sequence and capture presets that correspond with
the video format, frame rate and DVCPro format
you need to capture, edit and play back. To play
back DVCPro codecs, be sure to select the 8-bit
video playback preset for the corresponding video
format. Or simply use the appropriate HD Express
Easy Setup.
Other codecs
The HD Express supports capture and playback of
any HD or SD codec supported by Final Cut Pro,
including the file-based formats now supported by
Sony, Panasonic and other camera manufacturers.
To specify a codec other than ProRes or
DVCProHD, choose the HD Express Apple ProRes
preset that most closely matches the video format
and frame rate you wish to use, duplicate it and
then simply modify the duplicate preset, choosing
a different codec from the
Compressor
menu. For
further details about creating your own presets, see
“Creating capture/playback presets” on page 37.
