I have 2 questions. 1: can you start a run with your character in 3rd person. 2: Im on a Mobile tablet and when running Minecraft and my recording software I lag A LOT, how can i make this less of an issue.

So I know that key mappers can be used for things in a speedrun but I'd love to know if there is a specific "do" and "don't" list. Thanks in advance to those who answer :)

Im 95% sure that a rescource pack that gives you a button that can quick craft things on mobile would fall under "rescource packs that give you some sort of advantage" but if someone that knows better than me can tell me if it's illegal or not I would be very greatfull. :)
