Insta360 EVO (reviewed here), a popular VR180 / 360 camera, appears to have a stereo disparity issue that results in a hyperstereo effect even in distant objects. Fortunately, it is easily resolved with the right software, which can also be used with other VR180 or 3D 360 cameras that exhibit this issue.
Here is a video by my friend Hugh Hou from CreatorUp that demonstrates the issue. He shows how to solve it with Mistika VR.
Not everyone has Mistika VR. But the good news is that you can also also adjust the stereo disparity using a free built-in effect in Adobe Premiere CC 2019 called VR Projection. One of its parameters is called Disparity Adjustment. I applied a 0.5 adjustment (tip: you’ll need to type it in instead of using your mouse) and here is the result:
On the left side, you see the unedited image in anaglyph format. You can see there is a stereo disparity in the very distant cliffs and the distant parts of the path, which is an unnatural stereo effect (in the real world, distant objects should not appear in stereo). In Premiere, I applied VR Projection effect and set the Disparity Adjustment to 0.500. The result is on the right side, which appears to have eliminated unnatural stereo disparity.
You may notice that the side by side image now has a line in between them. That is because adjusting the stereo disparity has a cropping effect on each side of the photo. In any case, the line is invisible when the image is viewed in VR.
