Widescreen Guidelines

 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:

Widescreen video with graphics placed outside the 4:3 center-cut safe area

                                              Figure 1:                                                             Figure 2:

Left image on 16:9 screen. Right image on 4:3 screen.

Figure 1 is what the 16:9 viewer sees. A postage stamp image completely surrounded in black. No content is lost, but the video is shrunk 75% from full 16:9 size. Figure 2 is what the 4:3 viewer sees. This is a letterboxed image, and no content is lost. In the future, possible editing time charges will apply if delivered this way.

 

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:

Figure 3 shows full height video on a 16:9 screen. Figure 4 shows full height video on a 4:3 screen. No graphic content will be lost on a 4:3 screen. Video will not need to be re-sized.

Figure 3 shows full height video on a 16:9 screen. Figure 4 shows full height video on a 4:3 screen. No graphic content will be lost on a 4:3 screen. Video will not need to be re-sized or modified. Viewers on both 16:9 and 4:3 televisions will see video that fills the screen.
