Final Cut doesn’t “see” Io HD.
Check that Io HD chassis is powered up. Check that
Io HD Power LED (PWR) is illuminated and that Io HD
FireWire LED is illuminated (shows Io HD is
communicating with host Mac).
Media is not being captured from
desired external device.
Check equipment cables; outputs from external
device must be properly plugged into Io HD’s inputs
(ensure proper format and type) and check Io HD
front panel LEDs and Alphanumeric display. The
VIDEO LED will light to show an input is selected.
Look at the alphanumeric display and check that it is
correctly showing what you were expecting as the
input. Check the settings in the
Input
tab of the Io HD
Control Panel application.
Changes made to Final Cut’s
configuration aren’t remembered or you
need to force a change to them.
Under some circumstances, Final Cut Pro may need
to be initialized back to the factory default state as it
was when you installed it. The easiest way to do this
is to locate Final Cut’s preference files and discard
them.
To do so, follow this procedure:
1. Locate the file named “Final Cut Pro Preferences”.
Note: path to file is “Macintosh HD/users/username/
library/preferences/final cut user data.”
3. Click and drag that file to the Trash Can icon and
drop it there.
When you next start up Final Cut Pro, it will present
the “Choose Setup” prompt (as in initial installation)
where you can again choose a desired Io HD input
format in the “Setup For” pulldown and re-enter a
desired system scratch disk (your RAID).
Video in the canvas stays frozen during
playback.
1. The sequence setting does not match the
“playback output setting” found at FCP Audio Video
Settings -> AV Output.
2. Canvas/Viewer zoom setting exceeds the fit-to-
window setting. Change to “Fit-to-Window.”
Video output is black.
1. External video is set to “No Frames” (View ->
External Video).
2. The “Playback output setting” found at FCP Audio
Video Settings -> AV Output is set to “none” or to a
non-Io HD device.
Video stutter during playback.
RAID cannot sustain data rate.
Red render bar occurs when placing a
clip on a sequence.
The sequence setting does not match the clip setting.
