The only reason for interlaced video is due to the technological limitations of the cameras and televisions in the early years of television. Interlaced video could have been done away with not too long after the introduction of the transistor, but to maintain compatibility with the millions of old televisions already in use the interlaced format was kept. Today the only reason to use interlaced video is if you're doing a DVD that might be viewed on a CRT television or a flatscreen that isn't 1080p capable. Even then, it's not strictly required as DVD players automatically convert to interlaced through their composite, S-Video or component analog outputs. I'd stick with non-interlaced because it'll look the best on modern TVs and monitors. Let the laggards and late-adopters live with the jaggies! ;) (Unless they have some of the quite expensive old hardware with line doubling, edge filtering etc.) For HDTV, the resolutions have been pretty much nailed to a common standard around the world, yet there's still the stubborn insistence on keeping a large number of different frame rates. http://en.wikipedia.org/wiki/High-definition_television ------------------------------------ Yahoo!
