The Lumen5 media library consists of millions of free media files, but a small portion of them require the display of credits and attributions. Getty assets always require attribution, for example.
You may also include credits when uploading your own media files as well.
To help you steer clear of copyright woes, Lumen5 automatically generates required attributions when necessary and displays them on scenes in small print at the bottom left hand corner.
If you would prefer, you can enable a credit scene. All of the credits will appear on this one scene at the end rather than on the video itself.
