EX1 vs. RED

[Craig W. Bickerstaff]

Someone told me the HD-SDI output only provides 1080i -- you can't get 1080p out of it. Anyone know for sure?

I'm pretty sure it's 1080p out.

I was too. Someone who owns one told me it was only 1080i out the HD-SDI port. Hard to believe, though.

It will be 1080i I think, not many devices do 1080p over HD-SDI. You'd get a PsF feed in progressive mode.

If you look here he claims to have captured 24p via SDI at 4:2:2 color space, So I assume from this that SDI is in fact 1080p

Checked Sony's site on this. If you get Sony's brochure on the EX1 at http://bssc.sel.sony.com/BroadcastandBusiness/markets/10014/docs/PMW-EX1brochurefinal3-08.pdf and go to page 11, there is a chart on the upper right of the page that discusses HD-SDI output. It has an asterisk to a footnote at the bottom of the chart that says, "1080/23.98P recordings are output as 1080/59.94i signals via 2-3 pull-down conversion."

Sycophant: Got it. Must be progressive mode feed over 1080i.

So the answer is that it does do 1080p out the HD-SDI port, although via 1080i.

Thanks for the clarification.

we shot with that cam some days ago and now I can say that it is definitely no 1080p. it´s a fake p. find enclosed the picture of a moving person in the background - he becomes a ghost. so you can see that it is 1080i....

PsF is still progressive, it has no temporal difference between the fields.

I believe the output is always 1080i, isn't it? The progressive footage is embedded in a 1080i data stream. If you want 1080/24p, you'll have to strip out the pulldown.
