There is already full match capture on Minecraft Java, but not Bedrock Edition.

boss kills, player deaths, and other players deaths. Maybe white bags asw

Would be really cool for people who can do stuff like that and also if you want to share a clip with your friends.

Goals, Assist, KO, full matches, would help a lot

All who play marauders could record without worry of forgetting to record and without filling up storage. Cheating and bugs are a issue in the game and convenient recording could help devs of game to isolate issues.

kill of the monsters in dauntless and starts and ends of hunts or missions

Its useful because a lot of people wanna do arsenal and never miss out on one of a unexpected trick and they did not record it or they forgot to record it.

Add an auto event for when you defeat a boss (like Gronk or Bob). This would let people see that epic battle where everyone dies except you.

record chases and pallet stuns/killer blinds
