  1. I downloaded two mkv videos fromYoutube in 4K using 4kVideoDownloader, as ClipGrab couldn't do them, but now I can't convert those files or import them into any editing software, even though VLC will play them fine. Can anyone see what is wrong with the files?

    (link here to the files I make using 4K video Downloader): https://wetransfer.com/downloads/0a4b834447a5a35f3e70332349ffcbe720191128152811/e14d93...8152811/687c7d

    Would anyone be able to help me in finding a way to downloading these as a 4k mp4 (or anything FCPX can handle) file at highest settings?

    Thanks!

  3. Hi, Thanks for this. I'll need to have a sit down and work out this youtube dl program. I tried after readings comments on this board, but got very confused with it being command based.
