720×486 is/was a broadcast standard for many years, but it doesn’t use square pixels, it uses .91 or 1.21 sized pixels, depending if you are delivering 16×9 or 4×3. If they are asking for center cut, it sounds like they are expecting 1.21 pixels(Widescreen).
But here’s the thing, and I’ve made this mistake in the past at quite a cost. Get confirmation from the studio what they are expecting for Pixel Aspect Ratio. Then you can just press “cntl + K” and choose one of the NTSC D1 presets and you’re done.
Because your computer is square pixels, things will looked squished or stretch using non-square pixels. Under your comp window is a pixel aspect ratio toggle that will ‘correct’ for using non-square on a computer, but when you do this shapes/text will look all jaggedy, don’t worry about that, it will look fine when it plays on the air.
Oh…and again GET CONFIRMATION…trust me, it can be a very very costly mistake.
