Guidelines for delivery of widescreen 16:9 video
**IMPORTANT: Please deliver each spot in separate files and include at least 5 frames of slate**
KOMO-TV prefers delivery of 16:9 video with a 4:3 “center cut” protected area. The reason is that we have one signal that is fed to both our SD and HD channels. Many advertisers are delivering spots that are meant for the DTV standard, 16:9 full-height video with 16:9 title safe graphics. The reason why graphics need to be in 4:3 center cut region is that cable and satellite companies are still delivering 4:3 signals to their customers. Most will center cut the video and everything outside of the 4:3 area will get chopped off. When we receive these ads (usually in file format), we will modify and air as the following example shows:

To avoid any modifications of your video and to allow both 4:3 and 16:9 viewers to enjoy your video full screen, your graphics and framing should fall within the 4:3 center cut area. The following is an example of the preferred way you should deliver your video:

If your editing program permits, you need to set your safe zones for 4:3 center cut safe. Premiere CS3/CS4, After Effects CS4 and Grass Valley Edius have the ability to manually set your safe margins.
