OS X 10.11.6; Shotcut 17.04.02
I’ve got that when exporting intermediate/ProRes mov with fade-in and fade-out transparent images with Titles in second video track. It’s noteworthy I can export without crash H264 Main or High Profile mp4.
Transparent images are done by using File -> Open other… and then choosing “Color” in “Generator” -> Preselection “Transparent Title” (translated from french interface) and Titles using Title from Filters.
Rushs put in timeline are AVCHD mts or QuickTime mov.
