Hi mate. Is it you commented on this my video?:
Hike at Bombo park near Kiama, Australia
I tried to reply but something happening wrong, my message not sent on that page.
I did not found a way to send you a private message as well. So I will write the copy of my answer here:
How I made this video? I spent many many hours for experiments and found this way:
I am creating a project with 8192x4096 resolution in Adobe Premiere Pro. Then I am adding video from left camera to video track #1, video from right camera to track #2. Then I am synchronizing videos. How I am synchronizing? When I start recording video I am clicking fingers in front of cameras, and when I am editing videos I am connecting frames with this click to one point on timeline. Next step is changing the location and scaling frames. For video #1 (left) location is 2048 , 2048 , scale is 150. For video #2 (right) location is 6144 , 2048 , scale is the same: 150. Last step is adding Lens Distortion effect with curvature 29 for both (left & right) videos. These parameters are suitable for only GoPro 1080p video. For 4k video scale parameter will be different. Cameras with different lenses need different distortion parameter. Also cameras with different view angle need different scale.
I tried to do the same in Sony Vegas editor, but Vegas not supports 8192x4096 resolution for now.
