my celeste 3B video is 3 recordings put together

i only have. like. 2 major problems with playing on Xbox One 1. I can only record up to 10 minutes at a time, which makes it harder / more annoying to record longer things for my Youtube channel. 2. Controllers have begun to occasionally disconnect for a few seconds before reconnecting. I know it's a problem with the Xbox and not with the controllers because the controllers work just fine connected to my Ipad.
