I read the game rules and these questions weren’t answered.

Is video evidence required for run submits.

Is doing stuff with your controller such as holding the stick In one direction to modify neutral aloud.

Thanks to everyone in advance regardless of your answers.

1. Video is not required, but it is strongly recommended.

2. If by modifying neutral you mean doing L+R+Start on the controller to reset the neutral position, then yes that's perfectly fine.
