I recently switched to a Nikon Z50 myself for both videos and photos, moving up from a much older model. Like you, I was looking for something straightforward for editing. I ended up choosing Movavi, which many consider the best video editing software not just for videos but for photos too. It's been incredibly user-friendly with intuitive tools that make editing quick and easy, even for someone like me who isn't a pro.
Movavi has features like AI background removal, motion tracking, noise removal, and easy-to-use drag-and-drop filters, titles, transitions, and overlays. These features have been a vital for my projects, allowing me to focus more on being creative rather than figuring out how to use the software.
