HitFilm Pro is compliant with OpenFX version 1.3 and includes OpenGL rendering support. HitFilm Express does not support OpenFX plugins from third parties.
Compatible OpenFX plugins from other developers can be used inside HitFilm Pro. When you install compatible OpenFX plugins they will be listed in the Effects library alongside HitFilm’s included effects.
Note that some developers of OpenFX plugins restrict them to specific host platforms. If you are not seeing OpenFX plugins appearing inside HitFilm we recommend contacting the manufacturer of the plugin.
