Two Full HD 3D consumer video cameras were released in 2011:-
JVC GS-TD1
SONY HDR-TD10

Details and reviews of the camcorders can be found at http://www.camcorderinfo.com/

They both use 1920x1080i25/30 MPEG-4 MVC for 3D. Using interlacing at such frame rates provides much more fluid motion than the 1920x1080p24 MPEG-4 MVC used for Blu-ray 3D movies. It is vastly easier to use the cameras with these interlaced rates, as panning jitter is almost eliminated. The interlaced frame rates are also well suited to capturing sports action.

Full HD 3D interlaced formats of 1920x1080i25* for Europe, Australia, etc, and 1920x1080i30** for the USA, Japan, etc, are AVCHD MPEG-4 MVC formats, and not part of the Blu-ray standard, though some Blu-ray players will play them.

I am pleased to report that my PANASONIC TH-P50VT20A plasma display, acquired in 2010, will accept an HDMI signal in frame-packed*** 1920x1080i30 format from the HDMI output socket of a SONY HDR-T10 camcorder (a USA version). This provides a very fluid, high resolution 3D picture. I find the 30i 3D picture easier to view than 25i 3D. I put that down to the higher shutter glasses rate.

Please note that the JVC and Sony Full HD consumer videocams sold in Australia will provide 25i, not 30i.

Not all AVRs will pass 1920x1080i25/30 as frame-packed 3D, and not all displays will accept it (e.g. a cheap SONIQ 42" LCD display I purchased a couple of months ago, the L42D11A, won't). In these cases it will be necessary to set the camera to output side-by side 3D, resulting in some loss of visible horizontal resolution.

** Also known as 1920x1080i60. However, this is a rounded figure, The actual rate is 1920x1080i29.97 (also known as 1920x1080i59.94). For relevant details of the AVCHD standard, see http://en.wikipedia.....28AVCHD_2.0.29
