So now field "A" has him in one place (represented by half the image's pixels) and field "B" has him slightly to the left (represented by half the image's pixels). Uh-oh, he wasn't nice enough to stand still while this happened. The camera captures a field of him, then a 60th of a second later, it captures another field of him. Everything is happy in TV land.īut let's say there's a sportsball guy running across your screen from right to left. With 1080i, on the other hand, it's getting half a snapshot every 60th of a second (1,920x540 every 60th). It's that 1080i is worse with fast motion than 720p.Īt 60 frames per second (720p), the camera is getting a full snapshot of what it sees every 60th of a second. As we said earlier, this largely wasn't based on some limitation of the technology or being cheap. ABC and Fox very consciously made the choice to go with 720p over 1080i.
