Yes! Projects created in HitFilm Express or HitFilm Pro will open in the subscription version of HitFilm.
If you created your project using a feature or effect that's only available with a higher tiered subscription plan, there will be a watermark in the Viewer. Additionally, when you export the project, the effect or feature might be removed from your project.
For example, if you created a project with BorisFX 3D Objects, but you signed up for a Creator plan, then the effect will have a watermark. If you upgrade your account to Pro, then your effect will be fully restored.
