Im using Windows 10 built in screen recorder, and im unable to record multiple screen at once, which means that i cant use any timer. Is there any allowed timer mod that will display itself within minecraft window that i can use?

I'd really just switch to OBS. It's lightweight, Open source, easy to use and does exactly what you're asking for here.

I would, but it is way to laggy for me to use

timers dont matter

@BSRF same problem but timers dont matter like dinocharge said just say the time that the timer said

I know the are not required, i just think that having one is much better than not having it

I recommend you use this trick: First upload the video. After go to this page: https://mk8dx-speedrun-timer.azurewebsites.net/ after only simple. Wait the moment of start the run and quit 5ms too much time (If you gets bored you can do it with -50ms) and at the moment that dont are the camara modified and after put 5 ms and the moment that start quit -1ms 2 times and the moment that are -1ms to the start moment put 1 ms and you gets start time. with the end time is like the same but not modified camara. in end time is when you not passed the game and the other are the same.
