Rewind the video a bit or play the last scene again

[Abcd123kkk]

If I and my sister are playing a mobie and I want her to play a scene again , what should I use:
Can replay that scene again.
Can go back to that scene where the hero enters the room.
Can you rewind that scene again where the hero enters the room.
Can you rewind this video a bit?
Can you rewind this scene by 20s?
Which one of the above sounds natural?
Thank you

The first two need "you".

"Rewind" seems odd to me unless the movie is on tape, but "replay that scene again" and "go back to that scene where..." are both fine. You can also use "go back twenty seconds" or "go back a bit", usually adding an explanation for why you want to go back.
