Seems like Twitch just recently changed the format of the Clip video url again.
Looking at this API:
https://clips.twitch.tv/api/v2/clips/LazySuaveParrotBatChest/status
It now seems to be
https://clips-media-assets2.twitch.tv/AT-cm%7C{clip ID}.mp4
%7C is an url encoded “_”, not sure why they did it this way but that’s how it currently is.
Because Twitch now uses multiple ways for their video URLs it’s probably best to use the above mentioned API to get the right one for the Clip you want to download.
