Finishing HDV on Avid DS
The following procedure outlines the steps to take if you want to finish an HDV sequence on an
Avid DS system.
To finish an HDV sequence on an Avid DS system:
1. When in a 1080i/59.94 HDV project, transcode your sequence to DNxHD 145.
2. Export as an AFE.
3. Import the AFE file to Avid DS v7.6 QFE 3 or later.
Raster Dimensions
Some earlier versions of Avid editing applications allowed you to create projects based on some
device-specific HD compression formats, including 1080i 59.94 HDV and 1080i 50 HDV. Some
versions allowed you to set specific raster types for your HD projects — for example, DVCPro
HD. When you open existing projects that use these formats, current Avid editing applications
preserve the raster size (the dimensions of the video frame displayed in the monitor) for your
project and list the raster as an option in the Raster Dimension menu.
New HD projects on systems with supported configurations allow you to directly select the raster
size used for playback and editing. This allows your Avid editing application to support HD
compression formats that use anamorphically-scaled, nonstandard HD raster sizes. These
formats include those compatible with a variety of professional HD devices and standards.
Using the Raster Dimension selection lets you improve the playback of your HD sequences
without having to transcode the video to an Avid DNxHD resolution.
When you select an HD project format in the New Project dialog box, a Raster Dimension menu
appears allowing you to select from the formats available for the selected project type. This lets
you play back your sequence in the native raster size for certain HD formats. When you output
your final HD sequence, your Avid editing application resizes the sequence to the standard raster
size for your project.

Standard raster sizes for 1080i/1080p and 720p projects are 1920 x 1080 and 1280 x 720,
respectively. All other rasters are called “thin rasters” because the horizontal resolution is lower
than the standard rasters.
