Real world/HPX on Discovery HD?

In a nutshell, that's my question. Has anyone here used HPX footage for programming on Discovery HD?

I realize that this is another way to ask the eternal question about whether or not the HPX is good enough for high end broadcast use. I beleive that it should be but I would really like to collect some real world experiences, if possible.

Discovery HD's spec sheet calls for 1080i 59.94. It says they prefer masters in that format but will accept upconverts from 720P 59.94.

The project in mind has a fair amount of helicopter and wide scenery shots.

Any opinions appreciated.
 
There is a difference, The hpx500 is a bit softer. The hdx900 is more crisp. Im sure most people couldn't tell the difference though. But Im just saying, if your worried about them not accepting it for some reason, just use a camera they they usually shoot content on. If you really wanna go P2 though, go to koerner camera in portland and rent their hpx3000. That camera would greatly exceed their requirements.
 
I've just done two underwater HD shoots for Discovery Canada with the HPX500. It was done (as they requested) in 1080/60i and then dubbed over to HDCAM. The shots looked great.
 
60i is also called 59.94. 60i isnt really 60 cycles per second, its 59.94. (At least thats what I have been told anyways)
 
Hi Hunter,

Yes, that is how I understand it as well. 60i is really 59.94. I used a Sony F900r HDCAM (the newer version of the F900) recently and its menus never refer to 60i, just 59.94.

Is there a terminology conflict here?

i = interlaced non-progressive is built from 29.97 FIELDS per second.
P = 59.94 progressive full FRAMES per second.
 
No, it's 59.94 fields per second. Two fields are frequently (although inaccurately) referred to as a "frame" but they're still just a pair of temporally-displaced fields.

720p = 59.94 frames per second. 1080i = 59.94 fields per second.
 
Barry-

Is the reason for it being actually 59.94 cycles vs 60 cycles from electricity?

What is the reason its actually 59.94?

Thanks.
 
It used to be 60i up until color was added. In wedging the color signal into a system that needed to still be b&w-compatible, they had to slow down the frame rate 1/10th of 1%.

God love ya...that's exactly the response I was looking for. Real world experience.
Discovery Canada's specs seem to be the same as Discovery USA so that's great info.

Thanks,
