So, I made a speedrun any% of Nightcall on Xbox One S, but I recorded it together with an attempt that gone wrong. If I edit it so it'll only show the speedrun that worked, my speedrun will be invalidated? Sorry for my bad english.

you can post the raw recording. dont worry

When I recorded it, I didn't know how to put the in-game timer, so it doesn't have it, will they accept it or I'll need to make a new one?

the time is on the rating screen mate. use the visual timer in game is not necessary.
