![]() This scenario can happen if the spot is viewed on an SD TV or if the viewer is watching the SD feed on an HD TV. Imagine, for instance, that you are advertising a car with a price tag of $42,650, but when the spot is downconverted, a critical piece of that number gets cut-off and the price viewers see appears as 2,650. If an HD spot is not 4:3 safe, you’re not necessarily worried about “postage stamp.” Your main concern here is that nothing gets cut-off on the downconversion. If an HD spot is 4:3 safe (all action and titles are within the 4:3 frame), setting a “16:9 (alternative 4:3 center)” AFD flag will prevent the “postage stamp” effect if the AFD flag makes it all the way to the TV/receiver (not all networks and equipment support AFD). So why should you use AFD in your next commercial? And what problems can it help avoid?įirst, AFD is a great way to preemptively deal with “postage stamp,” the result of seeing black bars all around a spot (a combination of “letterbox” – black bars at the top and bottom – and “pillarbox” – black bars on both sides) on an HD TV when watching an SD feed. The codes can be used to determine how HD video should appear when downconverted and viewed in standard definition, regardless of whether the viewer is watching on an SD TV or an HD TV. AFD is a set of codes embedded in a broadcast video stream that can tell a consumer’s TV/receiver how to display video on the viewer’s television. ![]() Today’s topic is AFD (Active Format Description). In an effort to demystify some of the common technical terms used by the industry, we’re providing an ongoing “cheat sheet” of terms and tips advertisers can reference to make sure their TV spots look their best. Television spot production may be complex, but that doesn’t mean it needs to be difficult.
