Starting a new project [my 20+, been using for years, posted multiple travel videos on YouTube] and found NXT4 stable but rather than reinstall [will need to call and get reauthorized] I downloaded NXT8, after NXT7 continued to crash. Project is multiple formats: Panasonic Lumix DC-G9 [PL 12-60mm f/2.8-f/4], Panasonic Lumix DC-G9 [OM-D 12-100mm f/4] & iPhone Xr, typically audio is separated video sound & add to sound effects along with music, text inserted multiple ways using Internal tracks or on timeline crawling, scrolling or fading. Sadly I can't get beyond length of 5:01.21 and my travel videos run from 10-20min depending on the story.
Sometimes I get the Runtime Error Program ... Files (x86) Roxio Creator NXT 8\VideoUI\VideoWave.exe, but can be inconsistent just inserting a still jpeg or insering a png on an internal track
