Normally it takes around 1 second to extract the downloading url for videos like Youtube, for some videos it make take longer, but no more than 5 seconds. If the extracting process takes more than 5 seconds, you better check the settings of your browser, sometimes it is due to the extension like "uBlock Origin". The speed will be greatly enhanced after disabling such extensions. Otherwise, just clear the cookies of the browser, the problem will be solved most of the times.
When you copy a YouTube URL (even for a playlist), click in the WinX software to launch. You start with the "analyzer," which checks all the options. This tool also tried to default to the 1,920-by-1,080 version in MP4; I picked the 4K version (3,840 by 2,160 pixels) in WebM format, a subset of the MKV format—you can rename a .webm file to a .mkv and it'll work fine. In settings there are options to default to WebM at highest res. You can set up a number of videos to back up before you even click the download button. The 4K 575.4MB file took 1 minute and 39 seconds to download, more than double that of 4K Video Downloader.
Totally free, 5KPlayer from DearMob is a media-playing utility that is a lot more than a downloader—but it's got a heck of a downloader integrated. Promising no viruses, ads, or plug-in requirements is a good start. It is, sadly, one of the few I tested that asks for a registration of your name and email—you have to do that to get the full download function across 300+ sites. You may still use it if you don't register; I didn't and was able to download 4K vids from YouTube.
The last thing that I'll add is that the build quality of the software is excellent... any if you that have purchased Abbas' products in the past then you know that the quality of his software, and his customer support, are exceptional. I can’t imagine uploading all my videos all over again since I have over 500 videos in one of my accounts. I really needed this software!!
