on air is a one camera or the other system. it takes in the 2 streams and merges them to one. its meant as some sort of live broadcast thingy. wouldnt be any good for stereoscopic, or 2 angle shoots either.

terence.

Stuart, any news about possibility to capture two streams in parallel for 3D?

Nope... The client has pushed the project down the list for now - isn't THAT a familiar tune???

I've been promised they will consider it sometime next year. Who knows what equipment may become available by then! Maybe something easier/less costly than current solutions.

2x Blackmagic cards + Free On-Air + Mac Pro + 2 HV20's
 

Can we resurrect this thread ? It does appear that we can record 2 streams of HD with On-Air..

How about just clapping a slate in front of both cams before each take?

Sync issues
 

Even if the clapper is used to sync there are still issues..
For 24 fps, the shutter is 1/48 of a sec. Thus on an average the sync can be off for 1/2 of this i.e. 1/96 of a sec.

I am not sure if this is within or beyond the tolerance threshold..
