Hardware Conversion During Capture Or Playback - MOTU V4HD User Manual

codec you have chosen, core processor speeds, etc.
If you have a four- or eight-core machine, however,
you should be able to play back just about any
video format you wish.
HARDWARE CONVERSION DURING
CAPTURE OR PLAYBACK
The V4HD provides hardware-based conversion
features, which you can employ during capture or
playback in Final Cut Pro. Here are a few examples:
During log and capture, you could up-convert
■
SD to HD in the V4HD hardware and then capture
it in Final Cut Pro as HD. Or you could down-
convert HD to SD and capture as SD.
If you are capturing or playing back 23.976 fps
■
source material, you could insert pull-down to
29.97 during capture or playback.
As demonstrated below in Figure 7-7, you could
■
play back 480p 23.976 material from Final Cut Pro
and view it on SD monitors with pull-down
inserted by the V4HD hardware on output. At the
same time, you could also be converting it to 720p
or 1080p 23.976 with 14:9 pillar box formatting.
These are just a few examples. There are hundreds
of possible conversion scenarios. The following
table shows a summary of where to manage
conversion settings:
Figure 7-7: An example of hardware conversion during playback. Final Cut Pro is playing back 480p23.976. The V4HD
hardware is simultaneously inserting 2:3 pull-down for SD playback and converting to 1080p23.976 with 14:9 pillar
box formatting for HD playback.

or 1080)
HD to SD down conversion (from 720 or 1080 to
■
480 or 576)
Up/down conversion reformatting (letterbox,
■
