For connections with an Avid video peripheral, do 
the following:
1  
Connect the composite, component, S-Video, 
SDI or FireWire cables from the desired outputs 
of the video deck to the corresponding inputs 
on the video peripheral.
2  
Connect the audio source to the inputs of 
your primary Pro Tools audio interface
For connections without an Avid video peripheral, 
do one of the following:
„
For FireWire-based connections, connect the 
FireWire cable directly to the Firewire port on 
the Media Station system. 
Since video and audio are streamed in one signal 
via FireWire connections, it is not necessary to 
connect any audio inputs.
If you are capturing HD video, the video source 
must be connected directly to the 
Media Station|PT computer via FireWire (1394) 
cable. Because a single FireWire cable provides 
both video and audio, you must capture both 
audio and video into Media Station|PT and then 
export the audio portion over to Pro Tools if de-
sired. The exception to this is that if the deck 
also has analog outputs, you could connect 
those outputs to your Pro Tools inputs. 
For more information, see the Getting Started 
with HD Guide 
as well as the guide for your 
Pro Tools audio interface.
Capturing Audio and Video 
Caveats
The following caveats apply to capturing audio 
and video with a video satellite system:
• Due to technical limitations, when capturing 
video from a device being controlled via a 
1394 connection, audio sync will be up to 3/4 
of a frame out of sync.
• If you want to capture a 29.97 telecine video 
tape to a 24 fps project, you must first capture 
both audio and video on Media Station|PT 
and then export the audio back to Pro Tools. 
See “Capturing Audio and Video” on page 45 
and “Manually Exporting an AAF Sequence” 
on page 60.
Configuring Pro Tools and a 
Media Station|PT Video Satellite 
for Capturing
Before configuring Pro Tools and 
Media Station|PT for synchronized capturing, 
ensure that the two applications have matching 
settings. For detailed information, see “Match-
ing Media Station|PT and Pro Tools Settings in a 
Video Satellite System” on page 115.
Configuring Pro Tools for Capturing 
within a Video Satellite System
To configure Pro Tools for capturing audio:
1  
In Pro Tools, choose Setup > Session, and en-
sure the following:
• Clock Source pop-up menu is set to SYNC.
– and –
• Clock Reference pop-up menu is set to 
Video Reference (SD) or Video Reference 
(HD).
2  
Route the audio inputs to the desired tracks.
Due to variations in the analog and digital 
outputs of different decks, you may need to 
manually sync audio with video after cap-
turing.
