Hi i'm new to speedrunning im trying to submit a bedwars speedrun I followed the instructions of a mod to submit one but it keeps on saying invaild video link when I try to submit the replay file please help me figure this out.

I think they want to have a link to an uploaded video of your run, not a replay file.

Edit: I think you might have better luck if you try to contact the moderator yourself. But if you still need help, come back to this thread.
