Just loving the Xserve RAID here. It’s very nice.

Matt, that’s good to hear. Please send a copy my way for testing please!

Both! That’s one of the amazing things about this camera. It will do 1080p and 1080i (and 720p) and 480p and 480i.

G Field in Set 1 will do that. Best try the demo and see how it works for you.

I seem to remember the 4:2:2 notation first being used with digital video. Because with analogue video, the bandwidths of the chroma are never really integer fractions of the luma base bandwidth, I find it hard to see how such an integer based notation would have come about with analogue video. Anyone got any good historical reference on this? The only references I have are for digital video.

Digital video never has, does not have and never will have any setup. Setup is only for analogue NTSC video in North America.

But it doesn’t do 4:4:4, and doesn’t allow you to alter the gamma or colour balance or anything. The HDLink does, and BMD keep adding features with their firmware updates. The HDLink is a great product.

Say you’re shooting 60p, out of the component outputs to tape, or converted to SDI and captured direct to disk or something – what happens to the 30p you can record on the camera?? Does it drop every other frame or what? Surely the shutter speed would appear doubled on the 30p footage making it look very different to the visual appearance of the 60p?? Or are they going to do some magic smoothing jigger-pokery like they are giving the option for in the 24p mode?

Analogue is not 8bit, 10bit or 36bit, but noise limited, which can be equated to a bit level. Strictly speaking it’s not 4:2:2 or either, as that’s again a digital measure, but bandwidth can be equated to the equivalent digital x:y:z numbers. For what it’s worth, 36bit is nonesense – I doubt there’s any such thing and it’s totally impossible. I think what is meant is 3 channels of 12bit, which adds up to 36bits in total – like 24bit colour is 3 channels of 8 bits. To call some video 36bit sounds like creative marketing to me 🙂
For analogue outputs we need to know the frequency response within, say 3db levels, and noise levels in db, and then we can calculate what the digital equivalent would be. But converting to analogue and analogue transmission and subsequant conversion back to digital always incurs losses, so that’s why I made a point of saying earlier that I would never call a analogue output uncompressed – it may be devoid of digital compression with codecs etc., but it will have analogue losses of it’s own which make it a less than perfect representation.

Sure – the graphics card in your mac will drive two monitors, and you can use an HDLink to turn the 23″ into a HD monitor, linked over SDI cables to, say, a Decklink card.
