Once you have purchased FilmConvert, you will be emailed a license file in the form of an FKV file.
In order to use the FKV file:
Download and install the latest Trial version of the plugin from our website here.
Start either FCP or Motion.
Apply the FilmConvert effect to some media in order to get access to the FilmConvert controls. For instructions on how to do that, see Applying FilmConvert to your media.
Once you have access to the FilmConvert controls, find the Get FilmConvert drop down, which has two entries: Purchase and Activate. Select Activate.
Once selected, you will be presented with a new Window, FilmConvert Product Registration.
Hit the Load License File button and browse to your FKV file.
