Can I automatically download 1080p as best from youtube?

[Jofsey]

There is an arbitrary youtube video url. I want to download it in the best quality as it possible (as video+autio to a single file).

I know only the manual way to do it

1. youtube-dl -F <url> to get available formats
2. download by
   1. youtube-dl -f <video_format>+<audio_format> <url> in case of >=1080p (DASH)
   2. youtube-dl -f best <url> in another case.

Can I do it automatically by a single command?

To download best video and audio, you can use this command

youtube-dl ksP-KooXB4o -f bestvideo+bestaudio --youtube-include-dash-manifest

Thanks. It looks like what I'm looking for.
But it doesn't work for some old videos which have bestvideo presented only as webm.

My current workaround is

youtube-dl -f 138+bestaudio/264+bestaudio/137+bestaudio/best --youtube-include-dash-manifest

Fixed long time ago.
