Log And Capture - MOTU V4HD User Manual

your sequence. When Final Cut Pro is running, this
menu cannot be changed, as the playback format is
specified by your settings in Final Cut Pro.
In the Playback tab, make sure the Playback
Timecode Offset and frame rate match your Final
Cut Pro sequence offset and frame rate. If you are
working with drop frame time code, be sure to
choose Drop frame from the Playback 29.97 fps
Timecode menu (Figure 6-27 on page 53).
If you want Final Cut Pro to resolve to an external
sync source during playback, choose the desired
source from the Playback Clock Source menu
(Figure 6-28 on page 53); otherwise, leave it set to
Internal.
For interlaced output from the V4HD, use the
Interlace Pause Mode options (Figure 6-27) to
determine what you'll see when Final Cut Pro is
paused.
If you are at a point in your workflow where you are
not capturing video, or if you have no video inputs
connected to the V4HD, click the Setup tab and
enable the Playback only (disable inputs) option
Figure 6-19 on page 48.
For details on other playback settings, review
Chapter 6, "MOTU Video Setup" (page 41).

LOG AND CAPTURE

Once you've decided on a workflow, chosen the
corresponding Easy Setup preset for your Final Cut
Pro project and specified the video input you wish
to capture in MOTU Video Setup, you are ready to
log and capture video from the V4HD:
1 Make sure that the V4HD's Playback Only
option (Figure 6-19) in MOTU Video Setup is
disabled. See "Playback Only (disable inputs)" on
page 50.
2 Choose Log and Capture from the File menu.

3 Click the Capture Settings tab (Figure 7-5) and
check the Device Control and Capture/Input
settings.
These two settings are pre-configured if you
created your Final Cut Pro project using a V4HD
Easy Setup.
4 Click the Now button to start the capture.
Refer to Part IV of the Final Cut Pro manual for
more information on advanced capture settings
(such as batch capture, logging, etc.)

Video encoding and CPU performance during
capture
If you are capturing uncompressed SD, the
uncompressed video stream goes straight to your
hard drive, with no compression or encoding
required along the way.
When capturing any form of DVCPro (DVCPro25,
DVCPro50 or DVCProHD), the V4HD hardware
does the work of compressing the incoming
(uncompressed) video stream into DVCPro. The
V4HD then sends the DVCPro stream over
FireWire to Final Cut, which streams it directly to
the hard drive, with no further encoding necessary
on the computer. In this scenario, there is no
additional computer CPU overhead due to video
compression or encoding, since none is required
by the time the video stream reaches the computer.
