I am trying to export a rough cut of a short 3 min video I made for a client. I have been working from this same timeline for a while an exported a rough cut just fine yesterday. Today, I made a few changes to some fonts and moved around some clips per the clients request and then went to export another rough cut and I keep getting an error notice. I can't figure out what's going on or how to fix it. Please help! I have attached photos of my screen and the error message its giving me.
