your extension misses a format on this video

there's a vp9 webm 4K60p format in that video which you can select with youtube's quality button and it is not listed on your extension. i don't wanna install any downloader

Another way to download we can not.

savefrom.net lists horizontal 4k60p(format 315) but not vertical 4k60p(2160x3840@60/format 272)

If you want to download video in this format, install the program: http://videodownloader.ummy.net
