Playing or downloading videos from archive.org, on mac, help

Forum
macOS and Mac Apps

Hi,
I found a treasure trove of videos on archive.org containing one of my favorite newspeople, they don't have the download box associated with them, which is understandable. Is there an app made to download videos from archive.org? If not, how can I play the video in safari on the mac? It's hit or miss, but sometimes it will play a 1 minute clip of the video, then stop, other times when I click another clip, it either won't play or plays just a tiny snipit. Thanks in advance for any help. I'm using mac OS 10.15 catalina.
