There are a lot of discussions all over the web about how to perfectly synchronize 2 DSLR cameras for 3-D work...

Many people are working in this difficult issue.

And that is besides the most problematic issues with video in most DSLR's, that are:

1-Extreme aliasing and moire (due to line skipping read of the sensor)

2- Skew from the rolling shutter in most CMOS (there are already CMOS with Global shutters but AFAIK, none DSLR's have them yet)

3-Extreme video compression


And my question is this :

WHY try to reinvent the wheel???

MVC's (Machine Vision Cameras) already offer everything these people want for 3-D, and MORE:

-Perfect synchronization

-Uncompressed Raw recording

-2/3" sensor size for a deeper DOF, especially useful in low light with wide open lens apertures like f1,4

-Side by side stereo configuration down to 30mm StereoBase.

-Price, now with 2K cameras starting at $1500 US Dlls. I don't see a reason for a "shortcut"with other systems...

-Small Uncompressed Raw recorders

-Up to 340 fps for cool slow-mo 3-D!

-Better display for focusing and preview of cameras alignment with a laptop monitor having both displays side by side on the screen. And 3-D pre visualization with stereo viewers like these:

What else do you WANT or need???

The only thing is that MVC's wont make the coffee for you in the morning, sorry...;-)

Here is more info on the cameras:

To sum it up, people like DSLR's because they are f***ing lazy and ignorant. People can either pay up or learn the hard way. Most like the hard way.

I don't really think that hey are either...

They just want bigger sensors than the traditional small ones in camcorders, for the wonderful Bokeh they can get with such sensor sizes (especially with FF35mm sensors like the Canon 5D).

And of course the price of the cams for such "upgrade" is something not to disregard! (people paid a lot of money for 35mm adapters before)

I've seen guys doing video with their DSLR's at weddings, and they work more than if they were using a regular camcorder.

They are always fighting with manual focusing issues, and since most of them use prime lenses on their DSLR cameras, in order to "zoom in and out" they have to walk closer to the action or step back all the time....it's crazy!

I would never record video in a wedding with a DSLR, I am not that crazy yet! ;-)
