Matching the Media Composer
or Symphony 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 (described in Table 1 on page 44).
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.
Matching Audio Pull-Up and Edit
Play Rate
By default, Media Composer plays back se-
quences at the frame rate specified in the name
of the project type. For example, a 25i PAL proj-
ect plays at 25 fps. The notable exception is 30i
NTSC, which actually plays at 29.97 fps.
When working with 23.976, 24p NTSC, 24p PAL,
and 25p PAL projects, you can change the play-
back rate (known as the Edit Play Rate) without
affecting other properties in order to slow down
or speed up playback slightly. This is the video
equivalent of the audio pull-up/down setting in
Pro Tools.
To change the Edit Play Rate:
1 In the Settings tab of the Project window, open
the Film and 24P setting.
2 Select an Edit Play Rate matching your config-
uration according to Table 1 on page 44.
To change audio pull up/down settings in
Pro Tools:
1 In Pro Tools, choose Setup > Session.
2 From the Timecode Settings section of the Ses-
sion Setup window, select a rate from the Audio
Rate Pull Up/Down pop-up menu.
3 Click OK to apply the new pull up/down rate to
the session.
In most cases, changing the
Media Composer project type is not advis-
able and may not be possible. You should
change the Pro Tools Timecode Rate unless
you are creating an SD down-convert 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.
24p projects (PAL and NTSC) use a default
Edit Play Rate that does not match the proj-
ect rate. 24p PAL defaults to 25 fps and 24p
NTSC defaults to 23.976 fps.
