Edit Canon R7 & R5C VR180 stereo footage in DaVinci Resolve with Kartaverse KartaVR – Free EOS VR Utility Alternative
https://kartaverse.github.io/Reactor-Docs/#/com.AndrewHazelden.KartaVR
Kartaverse is a free open source post-production pipeline that is optimized for the immersive media sector. If you can imagine it, Kartaverse can help you create it in XR!
“Karta” is the Swedish word for map. With KartaVR you can stitch, composite, retouch, and remap any kind of panoramic video: from any projection to any projection. This provides the essential tools for 360VR, panoramic video stitching, depthmap, lightfield, and fulldome image editing workflows.
Kartaverse makes it a breeze to accessibly and affordably create content for use with virtual reality HMDs (head mounted displays) and fulldome theatres by providing ready to go scripts, templates, plugins, and command-line tools that allow you to work efficiently with XR media. The toolset works inside of Blackmagic Design’s powerful node based Fusion Studio and DaVinci Resolve Studio software.

Canada is no longer one of the richest nations on Earth
“… the problem with Canada’s economy is not cyclical, but secular; not one of utilization, but capacity. It is not so much that growth is temporarily below potential as that potential growth has slowed to a crawl.
More to the point, the economy is now growing slower than the population, which is why per capita GDP is now falling. And it’s per capita GDP that really counts, as far as living standards are concerned.
They are no longer one of the richest countries on Earth. Among the richer countries, they are on course to being one of the poorer.
The economist Trevor Tombe has shown that Canada’s richest province, Alberta, would rank 14th among U.S. states. The poorest five provinces now rank among the six poorest jurisdictions in North America. Ontario ranks just ahead of Alabama. British Columbia is poorer than Kentucky.”

Photography basics: Solid Angle measures
http://www.calculator.org/property.aspx?name=solid+angle
A measure of how large the object appears to an observer looking from that point. Thus. A measure for objects in the sky. Useful to retuen the size of the sun and moon… and in perspective, how much of their contribution to lighting. Solid angle can be represented in ‘angular diameter’ as well.
http://en.wikipedia.org/wiki/Solid_angle
http://www.mathsisfun.com/geometry/steradian.html
A solid angle is expressed in a dimensionless unit called a steradian (symbol: sr). By default in terms of the total celestial sphere and before atmospheric’s scattering, the Sun and the Moon subtend fractional areas of 0.000546% (Sun) and 0.000531% (Moon).
http://en.wikipedia.org/wiki/Solid_angle#Sun_and_Moon
On earth the sun is likely closer to 0.00011 solid angle after athmospheric scattering. The sun as perceived from earth has a diameter of 0.53 degrees. This is about 0.000064 solid angle.
http://www.numericana.com/answer/angles.htm
The mean angular diameter of the full moon is 2q = 0.52° (it varies with time around that average, by about 0.009°). This translates into a solid angle of 0.0000647 sr, which means that the whole night sky covers a solid angle roughly one hundred thousand times greater than the full moon.

Angular Size
The apparent size of an object as seen by an observer; expressed in units of degrees (of arc), arc minutes, or arc seconds. The moon, as viewed from the Earth, has an angular diameter of one-half a degree.
The angle covered by the diameter of the full moon is about 31 arcmin or 1/2°, so astronomers would say the Moon’s angular diameter is 31 arcmin, or the Moon subtends an angle of 31 arcmin.

What Is The Resolution and view coverage Of The human Eye. And what distance is TV at best?
https://www.discovery.com/science/mexapixels-in-human-eye
About 576 megapixels for the entire field of view.
Consider a view in front of you that is 90 degrees by 90 degrees, like looking through an open window at a scene. The number of pixels would be:
90 degrees * 60 arc-minutes/degree * 1/0.3 * 90 * 60 * 1/0.3 = 324,000,000 pixels (324 megapixels).At any one moment, you actually do not perceive that many pixels, but your eye moves around the scene to see all the detail you want. But the human eye really sees a larger field of view, close to 180 degrees. Let’s be conservative and use 120 degrees for the field of view. Then we would see:
120 * 120 * 60 * 60 / (0.3 * 0.3) = 576 megapixels.
Or.
7 megapixels for the 2 degree focus arc… + 1 megapixel for the rest.
