Forza Motorsports 5 Montage tips (Xb1 Upload Studio) [HELP]

Hi I play Forza Motorsports 5, and other games on Xb1, and make montages through upload studio. I’m having issues, I don’t know how to edit out the play, pause, rewind, etc, buttons that show up on the replays. Is there a way to do that? Or will I have to record during races?
