I had a video made almost a year ago that was an effective advertisement for my site. Once at the beginning, once in the middle, and once at the end, the domain name comes up on the screen for a few seconds each time. Since then, I changed domain names, and want the video on my new site, but with the updated domain name of course. Which program should I use and how can I edit out those few frames and replace them with the updated domain name? I am looking for a free program since it should be a quick change. Thanks for your help!
