To download videos from youtube in best resolution or in particular resolution like 1280*720p resolution using youtube-dl

youtube-dl --no-check-certificate -cio "E:/powerpoint_vba/po
weshell_linux/%(title)s.%(ext)s" --playlist-start 1 --playlist-end 7 -f best htt
ps://www.youtube.com/playlist?list=PL4URqfIIQcfBOtaSXl5tu4tYvpApw91Ew








that -f best is for best format available

say for example if we want to download the videos only in  1280x720 mp4 format we need to use
-f 22

youtube-dl --no-check-certificate -cio "E:/powerpoint_vba/po
weshell_linux/%(title)s.%(ext)s" --playlist-start 1 --playlist-end 7 -f 22 htt
