Matching Media Composer
and Pro Tools Settings in a
Video Satellite System
In order to accurately synchronize playback be-
tween Pro Tools and Media Composer, the follow-
ing parameters must be correctly matched:
• Media Composer Project Type and Pro Tools
Timecode Rate, Clock Reference, and Video
Format
• Pro Tools Audio Pull-Up setting and
Media Composer Edit Play Rate
• Timecode Format (Drop Frame or Non-Drop
Frame)
For Pro Tools to play in sync with
Media Composer or Symphony as a video satellite,
all of these settings are interdependent. A mis-
match in any of these settings will cause Pro Tools
to display an error message.
Media Composer Starting TC timecode setting and
the Pro Tools session start do not have to match ex-
actly, but should usually be close.
When working with 24p and 23.976 projects,
Media Composer defaults to displaying frames
mapped to 29.97 fps timecode. In order to keep the
Pro Tools and Media Composer or Symphony
timecode displays in sync when working in 24p or
23.976 projects, click the timecode display above
the Record monitor and choose
Sequence > Time-
code > 24 > Mas
.
Matching Media Composer
Project Type to Pro Tools
Timecode Rate, Clock
Reference, and Video Ref
Format
This section explains how to match the
Media Composer Project Type to the Pro Tools
Timecode Rate, Clock Reference, and Video For-
mat.
To ensure that your video satellite system will play
back or capture using the proper settings:
1 In Media Composer, click the Format tab in the
Project window.
2 Select the desired setting from the Project Type
pop-up menu.
3 In Pro Tools, choose Setup > Session.
4 Select a timecode setting from the Timecode
Rate pop-up menu that is compatible to the
Media Composer Project Type setting.
5 Make sure that a compatible clock source is
available and connected correctly.
6 Select the connected clock reference from the
Clock Reference pop-up menu.
7 Select a compatible video format from the
Video Ref Format pop-up menu.
To avoid sync problems during later stages of
post production, it is strongly recommended
in most cases to change the settings in
Pro Tools to match those of the sequence
open in Media Composer.
In most cases, changing the Media
Composer project type is not advisable. You
should change the Pro Tools Timecode Rate
unless you are creating an SD down-con-
vert from an HD project. See the Pro Tools
Reference Guide.
The Project Type is also established when
creating a new project in Media Composer.
Video Ref Format cannot be changed for
most HD frame rates.
