I used a web browser from a Windows 10 desktop and then waited 24 hours. It takes a while for YouTube servers to transcode above 2K.
In the video above, you can compare it to the original video file.
I uploaded the H.264 direct from camera with low bitrate as I felt it was going to get cut down by the YouTube servers anyway.
Would like to find a different way to sharing the videos that shows original quality and higher bitrate (at least 32Mbps)
