Question: Why to use the lenses so close, can you get real 3d?, its not a better idea to leave the cameras in "normal" position to obtain better 3d effect?
Document: If you have 2 GoPros and you are facing a unique event. you will want to get the chest mount or head/helmet mount.I got a special invite in one of the rarest cockpits and the 3D was awesome. plus you can still use each cameras footage as regular use as well. Have multiple batteries/class 10 memory cards on hand for the real rare events. don't want to be there and not get the footage.
i had 2 gopros already so... no brainer.3D is a bit tricky and time consuming to edit.... looks really impressive.... this product gives you full 3d HD footage and as long as your into working with the clips on a clip to clip basis... you'll get good results. This product does what it says... gopros are a little temperamental with this contraption, but I find the whole thing works 97 percent of the time.
I love the GoPro and just had to get a 2nd camera to do 3D. Better to be an early adopter and be ahead of the game. It's a little expensive, though. Guess you're paying for the Cineform software and such. I tested some timelapse this weekend at the VirginMobile Fest (one camera). It's subject to lens flare, so you need to make sure the camera is in a shadow even at a side angle to the sun.
I set my GoPro on different fixed objects (railings, signposts, etc.) with some sillyputty. What I didn't realize is the the silly putty would settle during the timelapse creating a natural tilt or rotation during the timelapse. I didn't know what to expect, but a timelapse always looks cooler with some camera movement (difficult to do evenly unless you have a rotating tripod head with degree markings). The rotation created a real nice effect as the sillyputty got soft and settled in the heat.
Love the 3D videos this system shoots. Look great on a large 3D screen. However, I sometimes have problems getting both cameras to come on at the same time. It takes a little while to ensure both cameras are set up exactly the same before using the system. Wish there was a way to attach my extra batteries to the cameras, but you can't with the cable attached. The free computer program is easy to use.
We would have loved to use an external mic, but the mic input side of the cameras face each other in the rig, so they can't be used. And the inability to use accessories like a battery pack or LCD screen with the 3D rig is a necessary evil, I suppose.3D quality isn't superb, you if you're expecting more for the price, you're dreaming. It's a fun gimmick, and hopefully GoPro irons out the handful of crippling issues it has. In short, wait for the next generation.
3D between 2 separate cameras is so much easier with this expansion kit!Rather with a manual setup where you have to manually mount and align 2 cameras side by side and try to get them to record at the same time, the case and sync-cable does all of that work for you.
I'm sure GoPro will eventually get this right, but for now, I'd recommend avoiding their 3D kit. We used this for a recent project and had two pairs of cameras running on two 3D rigs. I was nervous going in, because in testing, I found that the sync cables caused the cameras to behave erratically.
SInce I had two Hero 2 camera and was interesting in 3D, this seemed like a great kit to try. Problem is that the syncing between the cameras is  just not reliable. Both cameras have been updated to the same and the latest firmware. Both will initially start at the same time but pressing the shutter button stops one but not the other. It takes several more shutter presses to get them back on at the same time. But then the CineForm Studio software gets confused about what video goes with the other.
It would be nice if the other accesses to the cameras weren't covered up when they are put into the 3D housing (particularly the audio imputs for external mikes), but alas it is what it is and where else can you obtain a 3D underwater video camera (or one that will be out in the rain) for such an inexpensive price?OH ... unlike other consumer grade 3D systems these cameras ARE filming in a full 1080 30p for EACH SIDE of the video!
Answer: It seems to work OK with my cameras.  fwiw I have found that the best 3d effect is in a range of about 3/5 feet to 20/30 feet from the object being filmed.  Beyond 60/100 feet the 3d effect while there is not nearly as pronounced and does not add much, for me at least, to the 3d feel.   Filming in 3d I have found is very different from filming in 2d, at least if one wants the 3d effect.  (This may also be partially accentuated with the Go Pro due to the extremely wide field of vision.  I have NOT filmed with other 3d camera set ups, only the Go Pro)
