Choosing A Workflow; Hdx-Sdi Hardware Settings - MOTU HDX-SDI User Manual

CHOOSING A WORKFLOW
The HDX-SDI supports a range of SD and HD
workflows. For uncompressed HD or SD, all
DVCPro formats and Apple ProRes, the HDX-SDI
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 46.
Uncompressed HD/SD
The HDX-SDI 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 HDX-SDI 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 HDX-SDI 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 HDX-SDI 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
F I N A L C U T P R O
back DVCPro codecs, be sure to select the 8-bit
video playback preset for the corresponding video
format. Or simply use the appropriate HDX-SDI
Easy Setup.
Other codecs
The HDX-SDI 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 HDX-SDI 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 47.
