Video Frame Rate vs. Monitor
Refresh Rate
When you play back video on a monitor with a
refresh rate that differs from the video frame
rate (as is often the case during playback of
video through a DVI output), the output yields
visual artifacts and offsets in synchronization
between audio and video. For example, this oc-
curs during playback of a 24 fps video clip on a
DVI monitor with a refresh rate of 75 Hz.
If your workflow requires high-quality play-
back, you must output video through an Avid
video peripheral to an NTSC or PAL monitor.
The artifact and audio/video sync issues occur
as follows:
Frame “Tearing” & Video “Stutter” Frame “tear-
ing” is the horizontal distortion on rapidly mov-
ing or heavily edited sequences. Video “stutter”
is the subtle shifting of video during playback.
You can remedy one of these issues at a time
(but not simultaneously) using the Flip On Ver-
tical Sync option, located in the Full Screen
Playback Settings dialog.
Audio/Video Synchronization Offset Au-
dio/video synchronization varies slightly with
each frame. Though usually not noticeable to
the eye, more precise measuring devices cause
offsets in AV sync of up to 1/2 frame or more.
This is normal whenever using the output of a
computer's monitor card, and does not affect
capture, editing, or layback.
Cross-Mounting Media
Storage on Remote Systems
To simplify the transfer of sequence and media
files between Pro Tools and satellite systems
that are not connected to shared storage, it can
be helpful to mount the media storage of one
system on the desktop of the other system. This
practice is known as cross-mounting, and the
computer on which you are mounting that stor-
age is known as the remote system.
For example, you most likely want the local
video storage—which is physically connected to
the satellite system—to appear on the desktop of
both the satellite and Pro Tools systems. In ad-
dition, some workflows are simpler if the local
audio storage—which is physically connected to
the Pro Tools system—also appears on the desk-
top of the satellite system.
Cross-mounting audio or video storage on a re-
mote system involves the following steps:
 Choosing a storage configuration.
 Sharing the desired volume so that it can be
mounted on the remote system.
 Cross-mounting the shared volume on the re-
mote system.
