The free plugin supports downloading VODs, highlights and clips with the following URL formats

https://twitch.tv/videos/<numbers>
https://twitch.tv/<username>/clip/<clip_name>
https://clips.twitch.tv/<clip_name>
https://clips.twitch.tv/embed?clip=<clip_name>

Sub only vods are supported and will require you to login so Twitch can know that you have access to it. You cannot download sub only vods if your account doesn't subscribe to the channel it is on.



Like other upgraded plugins, the Twitch plugin can also download custom timespans (see Help menu->Documentation->Time Specifications) as well as all videos on channel pages (archive vods or highlights) and collections. These have the URL formats 

https://twitch.tv/<username>/videos/
https://twitch.tv/collections/<collectionId>
