I know about SPRT and yt frame timer don't tell me them. I need to make all the time retime perfectly (including 3 digit ms) how can i retime that perfectly?

Download the video and framecount

(which is exactly what those tools you mentioned do)

What do you have against sprt and yt frame timer? They work fine and are accurate.

use sprt or yt frame timer

yt frame timer isnt accurate (I think)

It is accurate.

@Cuber https://retime.mcbe.wtf is the better one (in my opinion)

I prefer sprt, just easier to use imo
