Video Watermark Editor for Your Own Videos.
Select a fixed or moving watermark manually, or use assisted corner-logo scanning and motion tracking. Review the selection, apply a masking treatment and export your edited video locally.
Import your video
Select the watermark area
Pause the video, then tap Start area selection. Drag on the preview to draw a box; native video controls stay available before selection mode starts.
Review & export
- Keep the selection box as tight as possible.
- Start with Soft blur at 2–5 px; increase only if the watermark remains readable.
- For a moving watermark, add keyframes whenever its position changes.
What this version can—and cannot—do
- Supports videos up to 5 minutes and 250 MB, subject to your device memory and browser codec support.
- Manual fixed and keyframed selection are supported. Assisted corner-logo scanning suggests a candidate region; template matching can track a selected logo at sampled intervals and stops when confidence falls. Neither feature is a universal AI detector: inspect and correct the timeline, especially after scene cuts, rotation, scaling or occlusion.
- Soft blur, pixelation and solid cover mask the watermark. They do not reconstruct the original pixels behind it. Clean content-aware removal needs a separate video inpainting model and may take substantially longer.
- Export is WebM. MP4 input can be opened where the browser supports it, but MP4 export is not provided in this browser-only version.
- Export runs in real time; a five-minute video can take about five minutes or longer. Large files may exceed the memory available on some phones.
Your selected video is processed locally in this browser and is not uploaded to a Zhatpat AI application server. Export uses the browser's MediaRecorder and canvas capture capabilities. Browser and device support can vary; audio is included only when the browser exposes an audio capture track. Keep this tab open until export completes.
