I did whole playlists with some having 700+ videos with yt-dlp; just add sleeps.
–sleep-interval 3 –max-sleep-interval 7, adjust as needed.
Streamfab always struggled with playlists from my recall, as in not getting proper resolutions or audio, etc.
yt-dlp you get what you want.
There was also a time or 2 I did teh –playlist-items 1,2,5,10
You can set that to whatever videos you want by number.
And also as said before, SF never gave choices with playlists; it was all or none and will get your account banned or limited if doing 100 or more at a time without the pause/sleep.
