I'm still new to using this software (I've only played with it for a few days), but I'm having lots and lots of fun just putting random videos together. I'm working on a "video tribute" to one of my favorite cartoon voice actors and all seems well...until I find that half of BOTH my audio AND video tracks are greyed out/disabled. What the heck happened?!
I've tried muting/unmuting, selecting/deselecting, NOTHING is working and I'm growing frustrated quite quickly as I have no idea how I did this.
