What a Stitch or Duet Is
Launch library · evergreen read

A stitch or duet is a video format that combines a new recording with an existing clip, letting a creator respond to, build on, or react alongside someone else's original content while keeping that original visibly attached throughout. The new addition can agree, disagree, extend, or simply react, all while the source stays fully visible.
The specific mechanics vary slightly between platforms, but the underlying idea stays consistent: two pieces of content, one original and one new, presented together in a way that makes their relationship immediately clear to anyone watching. That visible pairing is precisely what separates the format from a standard, disconnected repost elsewhere.
This format functions both as a creative tool and as a built in credit mechanism, since the original creator generally remains visible and identifiable throughout, unlike a standard repost that can strip that connection away entirely. Few other tools build credit so directly into the basic mechanics of how the content actually works.
