Hi i'm new to speedrunning and I would like to try and get into it. I was curious about what i need to submit a run though. Do i need a recording of it?

Most games will require a video submission in order to get add to the LBs. Some games may not require it though for times outside of say the top 10 or 20 or something. Just check the LBs for the game to see what the rules say and if you have any questions/it doesn't specify ask in the game forums.

thanks for the help
