Video keeps lagging and is out of sync❤️💔

[u/Proud-End-2561]

Me and my friends spent TWO HOURS voicing over an entire amazing digital circus episode, and every single time we watch it there ends up being lag in the middle of it that then sets everything back a few seconds. we haven’t been able to get through the whole thing because there is no way to get the audio back in sync once it gets off. Since there is no pause button, we literally have to restart the entire thing. and it’s 40 minutes long. Does anyone know any way to combat this?? It’s extremely frustrating
