Music, sound and pictures
Stock audio, video and photography come from Openverse, Freesound and Pexels. Every result carries its own licence, only results usable commercially are offered, and anything whose licence requires a credit is listed in the credits panel of the project it is used in — so the attribution travels with the video rather than stopping here.
