Just an FYI, it has been confirmed by testing that the EX-3 will output 4:2:2 10bit out of the SDI output while it's 420 and 8 bit to the cards. Improving green screen work tremendously. here's the forum for more info.

I do find it quite amusing when people tie themselves up in very complicated knots over this sort of thing. If it's 4:2:2 adjacent pairs of pixels will have the same hue value and if it's 8-bit padded out to ten they'll have values which are always a multiple of four. All of this is verifiable in Photoshop in about ten seconds flat and I don't see what all the fuss is about!

The EX1 and EX3 key very well from the recorded files, but a quick test of the HD-SDI feed will show that this will key even better.

I would hesitate to make any claims based on images I didn't generate.

I certainly can't evaluate whether it's 10-bit from an 8-bit image!

Usually consumer stuff like this has 8-bit 4:2:2 output.

Yes, sorry my mistake. Have you seen this?

Quite an exciting addition to the already brilliant EX-1 :)

The live HD-SDI feed coming out of the EX1 & EX3 is a true 10-bit signal. It is truncated to 8-bit when recorded to a card, so if one plays back material off the card it will be 8-bit padded to 10-bit. But live from the camera is absolutely true 10-bit.

Phil, this is straight from the specs and we have confirmed this is the truth. I know you have a great deal of knowledge on many things, but please don't make statements of a factual nature without first checking the facts themselves.

Pardon me, but I have made no statements about this particular camera whatsoever.

I assume you're referring to "Usually consumer stuff like this..." which is entirely true, regardless of what this particular item does.

Hey Phil, What do you know about the CineAlta XD Cam XE series. I find it amusing this forum placed this camera here as you qualify it as prosumer. As a newer member I find you to be no help to this thread. Someone with nearly 6000 post here I can't help but wonder if this is a place for professional or not.

Phil is most certainly a real professional with quite a lot of insight. He can come off as blunt, sometimes, but honestly he is a much needed, in my eyes, vocal critic and "but," person who has helped many users, including myself, through issues.

What equipment do you need to record 4:2:2 10 bit with the EX1?
I like to do some tests... but don't know what do i need to do it, can you record it directly to a laptop with a Blackmagic? :unsure:

Thanks in advance.
