Vixia G10 HDMI output
 
I'm assuming (That Word Again) the HDMI output on the XA10 and G10 are the same.

The colorspace seems to be a trade secret with Canon though.
Does anyone know if it's 4:2:2 or 4:2:0 ?

I'm thinking about piping mine to a Hyperdeck Shuttle.

Never mind, I finally found it.

So what's the answer?

It's compressed AVCHD as near as I can find 4:2:0.

Kinda disappointing because it looks like all The Panasonic camcorders (not DSLR's) put out uncompressed HDMI.

Can the difference even be seen?

Depends on how hard you grade it, but there sure isn't worth putting a compressed video on SSD's when you can put it on SD cards.

I think that 4:2:2 cams are the province of pro line cameras mostly, but I could be wrong. I think video shot for broadcast is supposed to be 4:2:2 if I'm not mistaken.

I almost bought the Canon XF100 partially based on the superior color space specs, but I don't shoot for broadcast. For my work the price didn't seem justified on my limited budget.

The HDMI standard only supports RGB 4:4:4, YCbCr 4:2:2 and YCbCr 4:4:4. See, for example, section 6.2.3 on pixel encoding on page 86 of the HDMI 1.3 specifications document.

Are you saying that the G10 and XA10 internal processing converts the image to 4:2:0 and then upsamples it to 4:2:2 before outputting it through the HDMI port?

No, I'm saying it outputs it as 8 bit 4:2:0 through the HDMI Port.
That's the best guess by the experts, but it is Compressed AVCHD of the port.

My AC 130 puts out uncompressed 10 bit 4:2:2 which makes it near perfect for the BM Shuttle.

I think your right Jeff.
Since the XA10 is billed as a low end Prosumer camera, I was hoping for uncompressed 10 bit, but I think they crippled it to keep people from doing exactly what I was considering...and competing with the higher priced models.

That's the same thing Panny did with the GH2.
