I'm a beginner and Ik this should be self explanatory but I just can't find one that doesn't require knowledge that I don't have.

Basically whenever I upload my runs to Youtube so they can be reviewed Youtube add a bunch of time because of delays. So I need a stopwatch to track my time properly on the screen so my runs actually count you know. If there are any suggestions that would be helpful, thanks.

LiveSplit. There are guides for it on YouTube. But you don't actually need to show a timer for the run to count.

@Derpeth thanks, I'll check it out.
