The free version of DaVinci Resolve is quite feature-rich and allows you to export videos without a watermark for the most part. However, if you decide to use OFX plugins or features that are exclusive to the paid Studio version while working in the free version, your output will have a watermark. This detail is important to know if you're considering using the free version for professional projects. The paid version, called DaVinci Resolve Studio, offers even more advanced features like multi-user collaboration, Noise Reduction, HDR grading, and more. But for many individual users and even some smaller professional projects, the free version provides a comprehensive suite of tools.
