3D pairs captured from video clips (cross-eye viewing method)

There are many problems with macro filming using two cameras....

I like 3D materials to have as many details as possible.
In 2012 I bought two Nikon D5100 cameras and built a beam splitter with a 50T / 50R mirror. I made a series of 3D videos shot in 1920x1080p, but I was not satisfied with the quality of the details provided.
The first capture is from a 3D clip with a size of 3840x1080 pixels (1920x1080/eye), reduced to 3000x844 pixels, so 1500x844 pixels / eye.
Not very bad, but I wanted more.

So, in 2014 I bought two Panasonic GH4 cameras that shoot in 4K, and in 2016 two Sony a6300 cameras that also shoot in 4K, but at a higher quality than the one offered by GH4.

The second capture is made from a single 4K frame that contains the images for both eyes, half a frame for each eye. I chose to contain an ant for comparison. Although it is 60% crop of the original content, it still offers a much higher level of detail than shooting with two cameras in 1080p in 2012. This system is easier to use, but the working distance is short.

With two 4k cameras I can use long focal length lenses, which allow a considerably longer working distance, useful for scared subjects, and the image quality resulting from 2x4k is significantly better.

My new videos are designed to be viewed with VR devices. As a result, the framing of the subjects makes it almost centered and with generous space around the subjects. This allows the image to be magnified so that the subject in the field of view is isolated (as example to the size of the grid marked in blue), and the head tracking system allows some observation of the environment around the subject, for better immersion.
