The Sony 3D Bloggie is probably the best (single) 3D video
camera below $1,000 - it produces better 3D video than the Fuji W3, the Optimus 3D and the Panasonic TM900/750 with the 3D lens attachment. It produces 1/2-frame sbs 108030p videos with stereo (AAC) sound.
Apart from the video specs and the lack of manual controls and everyone's favorite topic (interaxial distance), there are two issues with respect to sound:
1. The audio cuts out before the end of the video clip, sometimes by almost 1 second. This means that one cannot simply line up the clips on a timeline and produce a video without audio gaps, unlike for the clips of almost all the consumer camcorders I know.
2. The audio is pumped up, so background noise (not internal camera noise) is amplified.
All of this means to produce a watchable 3D video from the Bloggie clips one needs to edit more than with a standard camcorder.
There are two ways to deal with the audio cut-offs: (1) trim the ends of every clip so the audio ends when the video ends. (2) Use crossfade transitions, which are very easy to do in Vegas Pro or Platinum.
And then reduce the volume of the audio when there is only ambient background noise, which otherwise will be too loud.
This video makes use of crossfades to eliminate audio glitches and audio volume control. It is not just a test clip of someone's backyard, but an exploration of Bryant Park in NYC: there is ping pong, library reading inside and out, chess, a carousel ride, bocce, fountain play, and jazz, in 3D!http://youtu.be/QArdud3IYO4?hd=1
