Can you rip the video? It seems like youtube-dl doesn't support StoryFire. Searching the source code for .m3u8 gives this
https://player.vimeo.com/external/4...abee30ab8525d\u0026oauth2_token_id=1030312126
That URL doesn't work either. However if you fix it like this
youtube-dl -F
https://player.vimeo.com/external/4...bd69abee30ab8525d\&oauth2_token_id=1030312126
450 mp4 426x198 450k , avc1.640015, 30.0fps, video only
667 mp4 640x298 667k , avc1.64001E, 30.0fps, video only
1690 mp4 960x446 1690k , avc1.64001F, 30.0fps, video only
2983 mp4 1366x634 2983k , avc1.640020, 60.0fps, video only
5741 mp4 2048x952 5741k , avc1.64002A, 60.0fps, video only
5746 mp4 2048x952 5746k , avc1.640028, 30.0fps, video only (best)
youtube-dl -f 5746
https://player.vimeo.com/external/4...bd69abee30ab8525d\&oauth2_token_id=1030312126
You get a file! It's 410MB, and that's just the video. You need to get the audio too
youtube-dl -f audio-high-audio
https://player.vimeo.com/external/4...bd69abee30ab8525d\&oauth2_token_id=1030312126 -o audio.m4a
And then multiplex into one file
ffmpeg -i master-master.mp4 -i audio.m4a -c copy out.mp4
And then split
MP4Box -split-size 100000 out.mp4
And then you get these files
