How to make an 8K video with the GH5s by Kevin Luiz

Here it is! Interpolation of the Panasonic Lumix GH5S 2K 240 FPS VFR 24P to 8K ProRes HQ via Topaz Labs Proteus Engine. In my opinion, this makes our GH5S 240 FPS viable. Additionally, with the Chronos engine you can increase the frame rates by 1000% to emulate a Phantom Flex. This would require significant time to process as it looks at adjacent frames and pixels to interpolate the missing data, but it works significantly better than optical flow that you would find inside Resolve or FCP X. This 60 second clip however took me approximately 1 hour and 20 minutes to process inside Video Enhance with a Radeon VII in a Mac Pro 5,1 (flashed with Open Core). Enjoy!
