TG1 / TG3 Sony - workaround to sync?

[xeonbrite]

any idea on how syncronize two TG1 ??

I need to sycronize recording for 3D video...so sync must be perfect

via software???
via hdmi ?



I'm afraid it will end on rely on my two tumbs syncronism
or on building a meccanical control

I would imagine that software is the only way to do this.

Set up the 2 cams, start one then the other, shout "action" and that gives a sync point in editing.

I agree with the last post. It is easy to find the same frame and syncronize if you look at the soundwaves.

that's okay but 3d requires far more precision especially in fast movements

tecnically if you want the depths to be accurate , say, then shutter mis-sync errors should not lead to deviations more than 1/300'th the width of the film, for HD that would be 6.6 pixels

if the two videos did not started exactly at the same time fast actions will not give a good 3d effect

does anyone know if sony bravia system wich can sync playback can also sync recording?
