Short explanation for upscaling video to 4k on linux: ## use "ffmpeg" to split the video into frames ```ffmpeg -i /path/to/video.format -r FRAMERATE /path/to/frames/%08d.png``` ## use ffmpeg to split the audio from the video into a separate file ```ffmpeg -i /path/to/video.format -vn -acodec copy /path/to/audio.mkv``` ## use "Upscayl" in batch mode on the folder containing those frames and upscale each frame ## use ffmpeg to combine the upscaled frames with the audio file ```ffmpeg -framerate FRAMERATE -i /path/to/upscayled/%08d.png -i /path/to/audio.mkv -r FRAMERATE -vf format=yuv420p /path/to/output.mkv``` At any request to make a visual guide how to do this I will probably oblige just let me know. Thanks for watching the video!
