Matching the Media Station|PT 
Project Type to Pro Tools Time 
Code Rate, Clock Reference, and 
Video Ref Format

This section explains how to match the 
Media Station|PT Project Type to the Pro Tools 
Time Code Rate, Clock Reference, and Video 
Format (described in Table 1 on page 117).

To ensure that your video satellite system will play 
back or capture using the proper settings:

1  

In Media Station|PT, 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 Setups > Session.

4  

Select a time code setting from the Time Code 

Rate pop-up menu that is compatible to 
Media Station|PT Project Type setting.

5  

Select a compatible clock reference from the 

Clock Reference pop-up menu. When using a 
video satellite system, the SYNC HD or 
SYNC I/O must be locked to Video Reference 
(SD) or Video Reference (HD) at all times.

6  

Select a compatible video format from the 

Video Ref Format pop-up menu.

Matching Audio Pull-Up and Edit 
Play Rate

By default, Media Station|PT plays back se-
quences at the frame rate specified in the name 
of the project type. For example, a 25i PAL 
project 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 
playback rate (known as the Edit Play Rate) with-
out affecting other properties in order to slow 
down or speed up playback slightly. This is the 
video equivalent of the audio pull-up/down set-
ting 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 117.
