With Avatar having captured an Academy Award for cinematography, and several manufacturers having introduced consumer 3D televisions, it's starting to look like 3D may be here to stay. Presumably it's not an impractical crock as I'd kinda like to believe...
Frankly with the technology they're using it's not exactly going to be great quality.
I've recently purchased a GH2 with 14-140mm zoom for capturing video clips and noticed that a 3D lens is also available. I'm curious about the technology used when recording a clip with this lens. Since the camera has a single sensor, would the firmware key successive frames from the double light path separately as left- and right-eye frames and record them successively in an interleaved fashion?
Looking at Panasonic's site for the lens tells you most of what you need to know http://panasonic.net/avc/lumix/systemcamera/gms/lens/g_3dlens.html
ie it puts two squeezed images side by side on the sensor.
Could I hope to edit the AVCHD output with available software/supplied codecs and preserve the 3D nature of a clip?
I guess so, but you'll need to do some more home work on what format is needed to display this. I'd guess a Blu-Ray burner will be needed at the least, but you'll need to finds out if 3D needs non standard fiel structures or tags.
