Is 720/24PN considered HD??

Shooting in the 720/24PN mode gives you the frame size of 980x720 (I think), but true HD is the 1080i mode. From what I hear, this is the mode that a lot of people are shooting in, as am I. If 720x480 is SD and 1080 is HD, what is this 980 mode called?

Also, why can't we adjust the frame rates in the 1080i mode? Or am I doing something wrong? I'm only able to adjust the frame rate in 720 mode.

thanks,

720 is actually 1280 x 720 and it is HD. There's two flavors of HD.. so whoever is telling ya that it has to be 1080 is just giving ya one half of it. Several networks plan on doing 720 and several will be delivering in 1080. My buddy works for fox and they did an extensive focus/PR test with hundreds of people seeing the same footage in 720 and then in 1080. Apparatnly, less than 5 percent could tell the difference... so Fox is going with 720 as the costs.. and bandwith and a few more factors make 720 much more managable...

I think both are awesome.. You can only do the variable frame rates in 720, but you can up rez that in post. That's what I'm doing. I"m shooting 1080 on my TV show for everything that's not a variable frame rate...
 
"true HD" is either 720p or 1080i, according to the ATSC.

If you want to classify "true HD" as 1920x1080, you'll find that there's not a camera out there in common use that records that -- not even the $100,000 Sony CineAlta that George Lucas and Robert Rodriguez use will record that; it records 1440x1080.

Rest assured that 720/24P is completely high def. Just look at the images.

And Fox isn't going with 720 because of the costs, they're going with it because it makes a better looking picture for sports broadcast. All three of the major sports broadcasters (ABC, Fox, and ESPN) chose 720p.
 
I've yet to hear any complaints about how Fox's 24 looks at 720p. :) I know it's shot on film, but I'm referring to the transmission of it at 720p.
 
I did notice the whole 980x720 frame size when when i pulled it into at 1080i timeline.. i figured it had something to do with whole square pixel/retangle pixel thing on computers verse tv..

I know when i plug my camera into my hdtv it plays all my 720p clips full size.. does my tv know it's 720p and is just stretching it out??? cause it still looks like hi def compared to the regular hd channels I get on cable..
 
It is high-def.

How it's recorded is somewhat irrelevant; the TV expects a 1920x1080 or a 1280x720 signal, and that's what the camera gives it. The 960x720 is expanded back to 1280x720 on playback.

Again, there is practically no HD camera that records the full raster. Not even the $100,000 CineAlta F900 does that. The only one that I can think of offhand is the JVC HD1/HD10/HD100. Sony, Canon, Panasonic, everyone else does some form of prefiltering during the compression stage.
