Import/save videos from YouTube

I want to be able to save and import YouTube videos in my projects.

What is the best method or program in order to accomplish this? I am doing radar reanalysis and want to use tornado and drone footage incorporated in my projects.

Thanks in advance.

Used to do this via Safari and occasionally Firefox. Now Safari has jacked things up by disallowing extensions and Firefox is hit or miss as far as to which extension can pull a video from a specific page. This is quick and saves bunches of aggravation.

Download the Mac native app called ClipGrab.
clipgrab.en.softonic.com/mac

It's nice because you can (usually) download stuff in the native format Youtube stores it in, or at least displays it in. Or you can download audio only. Just paste your video link.

I like www.4kdownload.com/products/videodownloader/9

A couple of good choices, depending on your needs (not free and with some nice features):

Downie
software.charliemonroe.net/downie/
Downie is kind of cool, in that you can access all links on a given webpage. For example, if there are dozens of links on a webpage, you can have Downie manage and download the corresponding files, rather than having to do many, many "Save As..." operations. Also, for websites that require a login for access, Downie offers a "User-Guided Extraction..." feature.
