Full-Screen Playback via DVI 
Output to a Computer Monitor
With a supported video card installed, 
Media Station|PT provides full-screen playback 
of SD or HD video through a DVI port to your 
primary or secondary computer monitor. 
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. 
Supported Video Resolutions
Media Station|PT supports the import, capture, 
and playback of all video resolutions and frame 
rates (including HD video) supported by Avid 
Media Composer:
• Avid DNxHD (10-bit and 8-bit 4:2:2) at 1080i 
at 59.94, 50 fps; 1080p at 25, 24, 23.976 fps; 
720p at 59.94, 23.976 and 50 fps
• Native DVCPRO HD support for 1080i 59.94, 
50 fps; 720p at 59.94, 23.976 and 50 fps Na-
tive XDCAM HD support for 1080i at 59.94, 
50 fps; 1080p at 25, 23.976 fps 
• Native HDV support for 1080i at 59.94, 50 fps; 
1080p; 720p at 29.976 fps
• All standard-definition Avid OMF and MXF

• Avid IMX MPEG50, MPEG40, MPEG30, and 
OP1a files
• DV50, DV25 and DVC Pro 25 resolutions 
compressed with the Avid codec, including:
• DV25 411: DV25 interlaced scan at 4:1:1 
sampling (for NTSC 30i and PAL 25i 
projects)
• DV25 420: DV25 interlaced scan at 4:2:0 
sampling (for PAL 25i projects)
• DV25p 411: DV25 progressive scan at 4:1:1 
sampling (for NTSC 23.976p and NTSC 24p 
projects)
If your workflow requires high-quality play-
back, you must output video through an 
Avid video peripheral to an NTSC or PAL 
monitor.
For detailed information on the quality of 
DVI output to your primary or secondary 
monitor, see “Video Frame Rate vs. Monitor 
Refresh Rate” on page 45.
Media Station|PT supports the import, play-
back, and export of DNxHD video. DNxHD 
capture is not supported.
The oldest class of ABVB files (ABVB 
“MFM” files) are not supported in 
Pro Tools. These files were created with ver-
sions of Media Composer lower than 7.0, 
and do not have the .omf extension.
