quick reply from my collective of editing geeks is to get a download called videora.
Best of all, it’s free!!!! https://www.studioveena.com/img/smilies/icon_bounce.gif

this is a free iPod converter. ergo, this should mean you can get videos onto iTunes.
Doesn’t have minimum system requirements listed nor any OS exclusivity. https://www.studioveena.com/img/smilies/icon_lol.gif
