I need to shoot stereo video in perfect sync. I realized that GoPro offers Dual HERO System but they only list compatibility for HERO3+ Black Edition units. So I assume the currently selling cheaper HERO3 White Edition and HERO3+ Silver Edition models are not able to do frame synchronization for 3D even though they might have the same HW sync connector/socket as Black Edition on their bodies?
I do not need the waterproof dual enclosure, I can connect bare camera units just with cable (because I need wider lens baseline). My main goal is to get stereo video in perfect synchronization only.
