High-Definition Color Space

When creating graphics for high-definition video, you must keep in mind that SD and HD define colors differently. For standard definition, the International Telecommunication Union (ITU) 601 color space is used, while HD normally uses ITU 709. The most common problems occur when conversion occurs between SD and HD video sources. If the codec or video software doesn't automatically convert the color space, then a slight shift in color will occur.

These color shifts are only visible on a properly calibrated HD monitor that supports the 709 color space. However, most users are not designing with these hooked up so they won't see the issue.

Fortunately, it is rarely a problem as the color conversion process is fairly transparent and is generally handled internally by the video software application. For example, when Adobe After Effects converts from RGB to Y'CbCr in a video codec, the codec handles the conversion internally. When you export the same After Effects project to both an SD and an HD output, the process should work without issue.
