Resolution Specifications: MPEG
MPEG resolutions are specifically intended to support the SMPTE Type D-10 bit stream
produced and recorded by devices such as Sony MPEG IMX VTRs. They use 4:2:2 sampling.
The following table provides MPEG resolution specifications. Frame size does not include
blanking or VITC lines.
Resolution Specifications: VC1
Avid editing applications support editing and playback of MXF media encoded using the VC1
resolution and codec. VC1 was initially developed by Microsoft and has been standardized as
SMPTE 421-M.

Avid Interplay v1.2 does not support VC1 media.
(Windows) To use the VC1 resolutions, you must have Windows Media Player 11 installed on
your system.
The VC1 options appear in the Render tab and the Mixdown & Transcode tab of the Media
Creation Settings dialog box. These options also appear in the AAF Export settings when setting
the “Transcode Video To” option.
Depending on the project type and edit rate, you can fast copy import, play back, transcode, and
render VC1 resolutions. You must first export your sequence or clip as a Windows media file in
order to perform a fast copy import to your Avid editing application.
The following limitations apply to VC1:
For Macintosh systems, the VC1 codec is limited to playback only.
The VC1 codec is only available for Windows media. If you export to QuickTime, you must
export to a QuickTime-supported codec or transcode your sequence or clip prior to
exporting.
