A watermark is a visible mark \u2014 a logo, a text overlay, a repeating pattern \u2014 applied to an image or video so it can be evaluated without being usable. It’s distinct from a copyright notice: a notice identifies ownership on a clean file, while a watermark makes the file itself unfit for publication until it’s removed or replaced with a clean version.<\/p>
In a DAM, watermarking is a rendition-level operation, not a master-file operation. The system generates a watermarked preview or proxy for browsing and approval, and reserves the clean master for delivery after a license or internal approval clears. This split matters because once a watermark is baked into a master file, there’s no way to remove it without going back to the original source \u2014 the DAM has effectively destroyed the deliverable asset.<\/p>
Watermark placement is also a usability trade-off: a mark placed only in a corner can be cropped out, so libraries that rely on watermarking for real protection tile it across the frame or embed it as a semi-transparent pattern, accepting that this makes the preview less pleasant to look at in exchange for making it harder to lift.<\/p>","protected":false},"excerpt":{"rendered":"
