Many thanks. That seems to have worked although I don't understand what changed to create the strobing when it had worked successfully before. I have a newish Dell XPS with GeForce RTX 3050 and 16GB of RAM

When exporting my short video it now creates strobing/flashing. The VP view has no issues. I have successfully exported trial versions of the videos for comment but now, when complete, I get strobing. Have rebooted multiple times, changed file name, chosen options other than MP4, but no good.
