what's is like to record videos on xbox series x

when recording it doesn't save your voice. I think to record long videos and capture voice, you need a capture card. What I normally do, when 4 minutes up, I go and press start recording. And I can put the clips together. Once record a clip. I have it automatically upload to my Xbox network. Once uploaded, on phone/tablet, I can download clip, Then post on YouTube, or edit video in editing app, witch I use capcut.
