Get Back Experiment^3

I'm still practicing The Beatles "Get Back", it's basically ready for recording, but I decided to embrace the fad future and try some 3D video.  So if you are 3D playback equipped (or even if you aren't) have a look at this:

From a 3D point of view there are two main problems - the 3D depth is too deep, it comes across as artificial to me.  On my playback equipment there is also ghosting of the right eye on the left eye, and a little bit the other way around.  The depth problem is related to how I created the 3D, I haven't yet worked out the ghosting problem. I currently suspect it is crosstalk as a result of the over-depth 3D.

How did I do it? Yep, two cameras side by side, recording left eye and right eye.  Then a bit of synchronisation and cropping in VirtualDub.  Then putting them side by side using AVISynth.  Finally synchronising the audio from the microphone in Virtualdub.  YouTube takes the 3840x1080 file (ie two HD videos side by side) and does what it needs to do so you can see it in it's full 3D glory.  There is the problem, two cameras side by side, the spacing should be eye distance.  My two cameras side by side are a bit too wide apart even when touching.  Your eye will resolve it as 3D, but it's a bit weird.  Some thought will be required there.

From an audio point of view, it's rough.  It's cool, but rough.  When I do record it for proper I will ensure the recording is nicer, even if I have to resort to overdubbing/punch in.  Ah, they joys of editing digital audio.

So drop me a line and comment on audio and 3D - did one of the embedded videos work better than the other?
