60 Chapter 3 Combining Standard and High Definition Video
Tips for Converting Between Standard
and High Definition Media
When converting high definition media to standard definition media, you should do
one of the following:
 Use the Export Using Compressor command.
 Edit (or “nest”) high definition clips or sequences into a standard definition sequence
with the appropriate settings, and then export the sequence. This option properly
deinterlaces video before scaling, and then reintroduces interlacing after scaling.
For example, if you want to export a high definition sequence to DV NTSC settings,
create a sequence using the DV NTSC Easy Setup, drag the original high definition
sequence into the DV sequence, and then export the DV sequence using the Export
QuickTime Movie command.
Avoid converting high definition media directly to standard definition media by using
the Export Using QuickTime Conversion command with Browser clips in your project.
This approach may introduce interlacing artifacts when the video is scaled.
