Which 3D video setup?

how these guys compare to the hero3+ black in terms of IQ?

I think I came to decision, the new Drift Ghost S should be the lucky one (two) I hear much less issues with Drift cameras while the forums are full with stories on sd-card deaths, lost videos etc with gopro cams.

GoPro had an issue with SD card compatibility and performance causing cards to brick. Their latest firmware update seemed to resolve that. It's always a good idea to get a quality SD card and have two of them anyways.

Yeah, I' rather avoid the infamous, eating cards ~100 bucks apiece...

Any experience with the Drift cameras? The specs and the youtube shots look fine, I am more interested on the quality of their housing and its effect on the minimal focusing distance. As for 3D, the interaxial will be a bit exaggerate (~5") but considering the cam's close limit of ~1.5' (? dry value, UW I don't know) it should be OK.

5" is ok for distant subjects, but way too far for close objects.

I like to get close to my subject to get the benefit of my lights. With my Looxcie 3 rig even 3.5" lens-to-lens was difficult to edit into a viewable video. I reduced it to 3" and the results are better, but even at that real close subjects (like the octopus in this video) are at the limit of acceptability (and would benefit from some floating window modifications):

You should definitely consider working up a rotated camera mount for the Drift's to reduce the separation, IMHO.

Mount is one thing, ultimately one common housing would be the solution. Where to get one is another question...

I can add my experience, you can buy a 3D video camcorder, the lenses will be the correct distance apart, the JVC Evario TD1 I believe is the best of these as the CMOS chip is better at low light intensities, also it records full HD in Mpeg 4 format, there is an off the shelf housing from the USA...I used the green water setting and the red housing filter....I do not understand why anyone uses lights, the camera can see better than you can...what using lights does achieve is make the small area the light hits flooded with red light whilst the surrounding area is predominantly blue, the best thing to do is colour correct in post (editing) I edited using Edius7 from grass valley, its proud to take in any format and spit out any format, also its 1 month free trial, also used Stereoscopic player

I filmed around Raja Ampat

Hope this helps

Thanks for the feedback! This specific cam does only 1080i and the sensor is also smaller thus I am not sure about the low-light (underwater) IQ.

As for the interaxial: I would prefer a variable solution. For more distant objects (whole wrack, seascapes) a broader interaxial is better. It's not about reproducing the diver's sight - who sees everything beyond 5m in 2D - but providing a great 3D. Meanwhile for close-up, a narrower (1-2") separation would be the best - this is the case with the gopro 3d housing (45mm as I recall).
