Hi all, I'm a mom with two kids who are desperate to make a minecraft video of themselves playing minecraft that they can post on youtube. I've found several tutorials but they all focus on windows computers and my kids play on ipads. Is there any way to record themselves playing on the ipads? Do they need to use my mac laptop so they can save and then post the video?? Any help is appreciated. Regards, Clueless mommy
