Watermark

The word comes from papermaking, where a faint design pressed into the sheet proved its origin. Video borrowed the idea for the same purpose. A stock library marks previews so they cannot be used unpaid, a broadcaster marks footage so copies are traceable, and a short form platform stamps its logo and the poster's handle onto any video saved from the app.

For clippers and creators there are two watermarks to think about. The platform watermark arrives on downloaded videos and signals to every other platform that the clip was recycled, which Instagram has said it uses to reduce recommendation. The creator watermark is one you add deliberately, usually a handle in a corner, so a clip that gets reposted or screen recorded still points back to you. Some campaign briefs require one and specify where it goes.

The nuance is that removing a platform watermark is a technical step, not a licence. A clip that was someone else's work remains their work after the logo is gone, and a sponsor can still see that a clip was cut from a published post rather than from the source footage. The reverse applies too: an original edit does not become a repost because it carries your own handle.

In practice the routine is to cut from source files rather than downloads so there is nothing to remove, use a subtitle remover or crop when a download is the only option, and keep any watermark you add inside the safe zone so platform interface does not cover it. Small, low contrast, and consistent across every post is the usual guidance.
