Are you syncing a dual 3D rig? What degree of sync is good enough for a fiddle tune?
This video was recorded with my dual Canon rig, which you can see here: https://www.facebook.com/photo.php?fbid=651661424945761&l=c5c27d46ae
Watch this video in 2D or stereoscopic 3D by selecting your viewing options (for 3D TV or monitor, virtual reality viewer, stereoscope, 3D glasses, freeviewing, etc).
The YT3D native video file is parallel side-by-side squeezed.
