Video Attribution
Recoverable After Upload
Most attribution methods break the moment you upload your video. PixelSeal is designed to remain recoverable.
Compression doesn't break attribution. Resizing does. We solved for that.
18 real-world tests. No cherry-picking.
Your Video Goes Viral. Without You.
You post a video.
It gets 2,000 views.
Someone reposts it.
It hits 10 million.
Now prove it's yours.
What Happens After Upload
- Metadata gets stripped
- Visible marks get cropped or removed
- Files get re-encoded
- Resolution gets changed
Traditional attribution methods break.
Compression Isn't the Problem. Resizing Is.
Platforms don't just compress your video. They change its resolution. YouTube Shorts takes your 1080p upload and outputs it at 720p.
That resolution change breaks the 8×8 pixel grid that carries the watermark. Block boundaries land at fractional positions. The data is still there — but the structure that makes it readable is destroyed.
What Resizing Does to a Watermark Grid
Each block boundary shifts. The data is still embedded — but the reader can't find the grid anymore. That's why same-resolution survival is near-perfect and cross-resolution survival drops to zero.
The Approach
Platform-Aware Identity Recovery
Instead of fighting platforms, PixelSeal works with them. Embed at the resolution the platform will output. Identity remains recoverable because it was designed for what actually happens.
- Recoverable after WhatsApp video compression (25.7% strict verify, 94.4% partial)
- Recoverable after YouTube at matching resolution (100% strict verify at 720p)
- Recoverable after aggressive re-encoding (CRF 35, multi-pass)
- Works per-frame — every frame carries the full identity payload
Real Test Data
18 Tests. No Cherry-Picking.
25.7%
strict verify
94.4% partial — signal detected in nearly every frame
YouTube 1080p → 720p
0%
strict verify
Cross-resolution resize destroys block grid alignment
YouTube 720p → 720p
100%
strict verify
Same-resolution upload — full recovery
CRF 35 Multi-pass
Recoverable
aggressive re-encode
Heavy compression alone doesn't break the identity signal
How It Works
Three Steps to Proof
Seal
Upload your video. PixelSeal embeds an invisible ownership payload into the DCT coefficients of every frame — optimized for the platform you're targeting.
Upload
Share your video anywhere — WhatsApp, YouTube, your website. The platform compresses and re-encodes it. The watermark was designed for this.
Verify
Download the compressed version and run it through PixelSeal Verify. The system extracts the payload frame-by-frame and tells you exactly what survived.
Everyone Else
Most tools try to prevent copying. DRM, access control, download blocking. They assume you can stop distribution.
You can't. Not on the internet.
PixelSeal
PixelSeal doesn't prevent copying. It supports attribution recovery after copying happens. Your identity signal rides inside the pixels — designed to remain recoverable through compression, re-upload, and sharing.
“The best attribution system isn't one that stops copying. It's one that supports identity recovery after distribution happens.”
Honest Limitations
What Doesn't Work Yet
We publish our failures alongside our wins. If it doesn't survive, we say so.
- Cross-resolution survival is not solved yet — YouTube 1080p→720p still breaks the grid
- TikTok and Instagram video pipelines are untested
- Screen recording bypasses pixel-level embedding entirely
- Heavy compression can introduce visible artifacts in some frames

What's Next
We Haven't Solved Everything Yet
Cross-resolution survival is the next frontier. When YouTube outputs your 1080p video at 720p, the 8×8 DCT grid misaligns. We know why. We're working on it.
Multi-scale embedding, grid-alignment recovery, and adaptive block sizing are all in active research. When we crack it, you'll see the data here — not a press release.
Breakthroughs and failures alike get published. That's how trust works.
