I have Windows Movie Maker still on my PC, and it is and will always be my preferred software for making small personal videos. I have version 6.0.6002.18005. I am currently trying to put together 2 mp4 files at about an hour and 50 minutes. When I go to publish it, it stops progressing at 4% and the estimated time just starts climbing. It starts off at about 25 minutes, the last time I tried this, I gave up and hit cancel when it hit about 700 minutes for the eta. Why is this? I'm running Windows 10 version 1709 (OS Build 16299.371) on a brand new Dell Inspiron 15 7000 Gaming.
