Hi RGilmore,The software I use is pretty basic. But so far can handle anything I throw at it. Once you put your video on the timeline and render it. It runs very smooth with no lag. Also. Anytime you add a transition or adjust something. You need to tap the render tab again. But it only takes seconds. I use. "Wondershare Filmora" the paid version. But it was only like £40. And does what I need it to do.
Many thanks for the info. I am looking for a very easy soft and this one seems to me very good.
Thanks a lot
Alain
