I use Freemake Video Downloader for downloading YouTube videos.
It will usually offer better formats as well a .flv.
I usually download as .mp4 myself.
It also works with some other video sites.
The reason I’m posting this is Freemake Video Downloader comes with adware that’s too easy to accidentally install . I hope this will help prevent that for members like me that don’t want the “extra” adware.
This is the typical window of formats available to download.
