Just wanted to give some follow up. I changed the Video editing option from default to Intel graphics. For the first time ever, I was able to create an entire 8 min video without a hiccup. Usually in the past export would freeze once or twice and I'd have to restart the program, or when adding files along the timeline Videopad would freeze and I'd have to restart the program. Something would always happen.
Well, no issues this time. Maybe it was just beginners' luck but I'm keeping it set to Intel Graphics for now.
So now I'm wondering, if I get a dedicated graphics card will performance improve even more? i.e. time to export could be less than it is now?
