Windows Movie Maker 2012 is unusable for me since last year, once i do 10 or more Splits it play really slow and lag bad. I have a MSI GS43VR Phantom Pro-069 incase you want to see which laptop i have, it's a beast of a laptop but Movie Maker doesn't work no more after couple Splits, Sony Vegas Pro 15 work with no problem. I use a Canon EOS 77D to record my videos, Windows Movie Maker does the same thing when i record with the Panasonic Lumix G7. I know Windows Movie Maker was discontinued last year in January but i still like it, it's easy and simple to use. Any help on how to make it work without freezing or lag after couple Splits?
