I recently submitted a run that I did with two other people. These people don't have speedrun.com accounts. When the run was accepted, one person's name was shown to have an account connected to it. The run is now tied to someone who didn't do the run, and whom I don't know. What is the best way to fix this?

I was wondering if you could splice together the 30-second videos taken on the switch to have as proof for a run that is longer than 30 seconds?

For example, pressing record every thirty seconds (or less) during the run, saving the videos to my computer or phone, and stitching them all together.

I would only do this for shorter runs (sub 5 mins).
