I was on Apples HD site and they call, 480, 720, and 1080 HD.

But on the other side the numbers go all over the place:
720x 960
720x1264
720x1280

or
1440x1080
1920x 1080

ARe these size different because an editor did that? why is this?

also:
my camera hcr-hc3 says 1080 on it. So isn't everything that comes up going to have a 1080 side?
Or can I also get true HD at 480 or 720 sides. thanks!

Where on Apple's site specifically did you see this... please post the link.

The ASTC defines High Definition as *any* resolution higher than 720x480.

Most common HD sizes for broadcast are 1280x720 and 1920x1080.

1440x1080 is a very common acquisition size (used by HDCAM and other formats).

So-called "true HD" is merely a marketing term. Try not to get hung up in marketing terms.

Thanks Chris:
Well, for this project, saying I'm shooting in true HD, may be an important thing, so I need to get it right. My editor said you need 1080 or 1280 to be true def, buy you are confirming then that you can say true HD at 720?
