I have an Xbox, but for longer runs, I have to use my Ipad and record my TV screen. Is this ok, or do I have to record it a different way?

If you record on twitch, you can make it so it saves broadcasts for 2 weeks that way after your xbox streeam the game play will be saved for two weeks. You will also need to connect your YouTube to Your twitch so when the stream Is finished you move the stream to YouTube. so long as you have access to a computer within two weeks you can upload the video to YouTube in good quality

There's a button to move the stream to YouTube directly from twitch on a browser.

but since I'm a little square brain, I don't know how to do any of this, so that's why I just record with my iPad. But I still didn't get my question answered: CAN I USE MY IPAD TO RECORD

Yes, as long as the screen is fully visible.

Also you can stream directly to twitch if you download the twitch app on your xbox
