Visible watermark vs SynthID: what removing the logo does, and doesn’t do

AI-generated media from Google can carry two quite different watermarks. It helps to know which is which before you edit and publish anything.

The visible watermark

The small sparkle in the corner (and on some videos, a “Veo” text mark) is drawn on top of the picture. It tells viewers at a glance that the content was AI-generated. It is a visual overlay, so it can be measured and reversed, which is what ClearFrame does.

SynthID: the invisible watermark

SynthID is Google DeepMind’s invisible watermark. It is woven into the pixels (and audio) of generated content in a way people can’t see, and it is designed to survive common edits such as cropping, compression, filters and frame-rate changes. Google provides tools that check for it.

ClearFrame does not remove SynthID, and doesn’t try to. Removing the visible sparkle changes a few thousand pixels in one corner by a small, precise amount; the invisible watermark is spread across the whole picture and is not affected. Content you clean with ClearFrame can still be identified as AI-generated by tools that read SynthID.

Metadata and content credentials

Some files also carry metadata that describes how they were made, such as C2PA “content credentials”. Like most video editors, ClearFrame writes a brand-new file, so this metadata is not carried over. If you need to show where a file came from, keep the original.

So why remove the visible logo at all?

Usually for presentation: the sparkle distracts in a showreel, a product demo, a client presentation or a video that will be edited together with other footage. Removing it is about how the content looks, not about hiding where it came from. That is also why it is important to keep being open about AI use.

Be open about AI content

Many platforms require realistic AI-generated or AI-altered content to be labelled, and laws such as the EU AI Act require deepfakes to be disclosed. Removing the logo does not remove that duty.
