I updated this to a 4K 60 fps version and posted on YouTube - embedded below. I don't know if YouTube will eventually offer it as a 4K 60fps video but PTE AV Studio 10 Pro does a wonderful job with 4K video as I discovered when I installed a new nVidia GTX 1660 Ti GPU with 6 Gig RAM and a 28" Samsung 4K display on my Win 8.1 system. So far I'm only seeing 1080 p on the YouTube link, but hopefully it will eventually be available in 4K for those with the bandwidth and hardware to support it.
Best regards,
Lin
