View Full Version : Vixia G10 HDMI output Don Litten July 28th, 2012, 02:35 PM 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. Don Litten July 29th, 2012, 10:16 AM Never mind, I finally found it. Eric Olson July 29th, 2012, 08:27 PM Never mind, I finally found it. So what's the answer? Don Litten July 29th, 2012, 09:39 PM 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. Maurice Covington August 2nd, 2012, 02:24 PM Can the difference even be seen? Don Litten August 2nd, 2012, 08:12 PM 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. Jeff Harper August 3rd, 2012, 08:16 AM 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. Eric Olson August 3rd, 2012, 10:45 AM It's compressed AVCHD as near as I can find 4:2:0. 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. https://engineering.purdue.edu/477grp10/Datasheets/CEC_HDMI_Specification.pdf 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? Don Litten August 3rd, 2012, 04:02 PM 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.

For my work the price didn't seem justified on my limited budget. 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. |
