Why is it needeed to record with internal sound? I don't have rooted device so I can't do it

Hey, sorry for the confusion! You can definitely record with external audio -- my phone isn't rooted either so I always use external sound. Let me know if you need any other resources (recording, timing, etc.)

Why is it needed? For verification? I'v got world recod wideo but without sound

Its best to have sound so I can verify that you've submitted one continuous video, not something edited. If there were 20 people on this leaderboard and you were trying to claim first place, I would be a bit suspicious. Its also for standard quality -- we want more people to get interested in speedrunning, so we should at least make a watchable video.

For now, you could use YouTube sound editor to put in a free sound track (its very easy, let me know if you need help). Submit that, and you should try to run with sound next time :)

Okay thanks. Recorded next video with sound and sumbited.

I don't see your submission -- try submitting again?

Submited
