How to remove the Sora watermark
The Sora mark can change position during a clip, so a fixed blur or crop doesn't work. Imaginoa looks for it in short stretches of the video and learns each spot separately.
Step by step
- Download your original video from Sora. A screen recording loses quality and makes the mark harder to find.
- Drop it into the tool above. The scan shows "Looking for moving watermarks".
- Each spot where the logo appears gets a box labelled "Moving watermark".
- Drag the timeline to check a few moments, then tap "Remove watermark & save video".
If the logo is missed
- Move the timeline to a moment where the logo is visible.
- Tap "Draw area" and drag a box around the whole logo, including the icon.
- Repeat for any other spot where it appears. Each box is only used on frames where the mark is actually there.
How the video remover works
No uploads and no waiting in a queue. Your browser does everything.
- Add your videoChoose an MP4, MOV or WebM file. It is opened directly on your device.
- The watermark is foundA watermark stays still while the video moves underneath it. Imaginoa spots those fixed edges, then learns the mark's exact shape, transparency and colour from many frames.
- Every frame is cleanedSee-through marks are mathematically reversed to bring back the real video underneath. Solid parts are rebuilt from the surrounding texture, so the spot stays sharp.
- Save your videoYour clean video is saved as MP4 (or WebM on some browsers) with the original sound.
Works best with
- See-through text or logo marks in a fixed spot, like those on AI-generated videos.
- Videos with movement, so the background under the mark changes.
- Short clips, from a few seconds to a few minutes.
Limits to know
- Marks that move around the screen can't be removed automatically.
- Under a solid logo the original video was never visible, so that spot is rebuilt from nearby texture rather than recovered exactly.
- Invisible watermarks like SynthID are not removed, and it's not for other people's videos.
Video questions
Looking for photos? Use our image watermark remover.
Does it work when the Sora logo moves?
Yes. The tool checks short parts of the video separately, learns each position, and only cleans frames where the logo is present.
Is my video uploaded?
No. Everything happens in your browser, so the video never leaves your device.
Will the sound be kept?
Yes. The original audio is kept in the saved video.
Does it remove invisible watermarks?
No. Only the visible logo is removed. Invisible provenance data added by the video platform is not touched.
Can I use it on other people's videos?
No. Please only edit videos you created or have permission to change.
