Unfortunately I missed the Vegas upgrade by perhaps a day or two and was stuck with version 18. I've had nothing but continuous problems after upgrading on a custom built PC with an MSI motherboard, 64GB of RAM, SSD drive and plenty of Intel CPU firepower (i7-11700k) on Windows 11. I recall the old days when odd/even upgrades were like versions of Star Trek, and I recall the odd providing better results (I've been around since Vegas 5.)
About 80% of the time when I render using the Magix templates, my computer will automatically restart at some point during the rendering process. I'll use templates like 1080 with 60fps equivalent, 30fps or the 2160 version. Two pass can create more problems. I am NOT choosing the wrong CPU (e.g. AMD) It is absolutely infuriating. I haven't been able to isolate the problem. I can have no other applications open and it also will break the rendering process. Could anyone advise? At the moment, I've had to consider using an alternative since I can only get 1 of several attempts to render.
