Hi, i dont have a fast upload speed, because of that I no go live on twitch, I want to know if I can do Segmented runs on FF9 steam version using autosave function. And one more thing I do not know how to pause and save the time in the livesplit, to continue later, if it is possible. And if possible somebody help me I will be grateful.

The main leaderboards go by real time, so you are not allowed to pause the timer during a run. A true segmented run involves trying segments over and over to get each segment as fast as possible before moving on, which judging from your post I don't think is what you want to do. Of course you are free to do runs in segments if you want, but for the main leaderboard runs are required to be in one segment.

Ok, thanks for the answer.
