While Headliner allows its forever free and Basic users to export as many videos as they wish, a "Video Made With Headliner" watermark will appear on exports after a Free user exports 1 video or a Basic user exports 10 videos per month.
If you want to export unlimited videos without a "Video Made With Headliner" watermark you can do so as a Headliner Pro user. Headliner Pro users can also add their own watermark to their projects.
