I'm using Movie Studio 2022 Platinum, Version 21.0.2.138 (UDP3)
When I export to pretty much any format (I've only tried MPEG-4 and HVEC) from Movie Studio Platinum 2024, artifacts appear that do not appear when I export the same movie from Movie Studio Platinum 2022. They seem to occur around even the most basic transitions, like Cross-fades. See attached.
