Remove Watermark From Video Online
Video watermarks aren't a single mark — they're the same logo baked into every frame, sometimes drifting position or pulsing in opacity. WatermarkRemoverAI treats a clip as a sequence: it tracks the marked region across frames and inpaints each one so motion behind the watermark (a moving background, a panning shot) is reconstructed rather than smeared into a frozen blur. Mark the watermark once on a reference frame and the same region is cleaned through the clip.
How to remove a watermark from a video
Upload your clip
Drop in an MP4, MOV or WebM. Pause on a frame where the watermark is clearly visible — that's your reference frame for marking.
Brush over the watermark once
Paint over the logo or overlay text on the reference frame. If the mark moves around the video, widen the brush to cover its full travel area so no edge is left behind.
Process and download
The AI rebuilds every frame under the mask and re-encodes the video. Download the cleaned clip at its original resolution and frame rate — audio is untouched.
Good to know
Video is processed frame-by-frame, so it is heavier than image removal — longer or 4K clips run on Pro. Mark a band covering the watermark's full range of motion, not just one position.
Frequently Asked Questions
Will the cleaned area be blurry like other video tools?
No. Cheap tools blur or crop the watermark region. WatermarkRemoverAI inpaints — it predicts the pixels that belong under the mark from surrounding frames and texture, so the patch stays sharp and matches the moving background instead of leaving a soft smudge.
Does it work on 4K and 8K video?
Yes. Processing is resolution-independent; the output keeps the input resolution. High-resolution clips take longer per frame and are handled on the Pro tier, which lifts the free daily cap and enables longer, higher-resolution renders.
The watermark moves around the frame — can that be removed?
Yes, as long as your brushed region covers everywhere the watermark travels. For a mark that bounces or slides, paint a band that spans its full path rather than a tight outline of one position.
Will the audio or frame rate change?
No. Only the video frames are edited. The original audio track, frame rate and duration are preserved and remuxed into the output file.
How long a video can I process?
Short clips run on the free tier. Longer videos, higher resolutions and batch jobs are Pro features because every frame is individually inpainted, which is far more compute than a single photo.
Is it legal to remove a watermark from a video?
Only remove watermarks from footage you created or are licensed to edit — your own recordings, or clips you hold the rights to. Stripping a watermark from someone else's copyrighted video to republish it is not something this tool is intended for.

Automate it with the API
Send a file, get a job id back, poll for the clean result. Same AI engine as the web tool, in two requests.
curl -X POST https://api.watermarkremoverai.com/v1/watermark/remove-video/ \
-H "Authorization: YOUR_API_TOKEN" \
-F "files=@video.mp4" \
-F "auto_detect=true"
# => {"uuid": "..."}
# Poll for the result
curl -X POST https://api.watermarkremoverai.com/v1/watermark/results/ \
-d "uuid=..."
import requests
API = "https://api.watermarkremoverai.com/v1/watermark"
headers = {"Authorization": "YOUR_API_TOKEN"}
with open("video.mp4", "rb") as f:
job = requests.post(API + "/remove-video/",
headers=headers,
files={"files": f},
data={"auto_detect": "true"}).json()
result = requests.post(API + "/results/",
data={"uuid": job["uuid"]}).json()
print(result)
Prefer a manual mask? Send mask=@mask.png instead of auto_detect, or pass mask_x / mask_y / mask_width / mask_height (add mask_is_percentage=true for percentages). Optional dilation=5 grows the masked area.
