Multi-lingual 4K Video Downloader (4KVD) is frequently updated and features clear download links on the program's website; no ad traps here. The software does what it advertises in a simple interface: grabs videos up to 8K in quality and downloads to plenty of formats. Just copy a YouTube URL and click the Paste Link button to get started. 4KVD will even grab subtitles, entire playlists, and all the videos in a channel to which you subscribe. The sites supported are limited to the big names like YouTube, Vimeo, Facebook, and a few others, but covers most of what you need.
