A clip showing celebrities apparently condemning Kanye West's swastika T-shirt went viral — and within hours, fact-checkers confirmed it was fully AI-generated. No actors, no real footage. Just pixels and a prompt. The video spread across Instagram, TikTok, and Reddit before being pulled, but the damage was done: millions saw it before the label changed. The uncomfortable truth is that this wasn't a one-off. AI-generated content is flooding platforms right now, and the detection systems hunting it have gotten much sharper in 2026.
If you're creating AI video or image content — even legitimate, clearly-labeled content — you need to understand what platforms actually scan for. It's not magic. It's metadata, bitstream signatures, and missing phone-capture signals.
When you upload a video or image, platforms run it through automated classifiers that look for three categories of signals:
C2PA / Content Credentials (stored as JUMBF atoms). This is the cryptographic manifest that Adobe, Microsoft, and the C2PA coalition built into AI generation tools. When Sora, Midjourney, or Runway exports a file, it embeds a signed manifest describing the file's AI origin. This isn't hidden — it's a structured block of JUMBF data that forensic tools like ExifTool can read directly. Instagram and TikTok both scan for this manifest. If your file has C2PA atoms with a digitalSourceType of trainedAlgorithmicMedia, it's flagged before a human ever sees it.
XMP metadata AI flags. Beyond C2PA, many tools write XMP properties that explicitly mark AI generation: DigitalSourceType, generator, tool, or software fields. A raw Sora export typically carries 144 metadata tags. An AI image from Midjourney will have generator-specific fields baked in. Reddit's automated systems and YouTube's content ID both flag files with these properties present.
Encoder fingerprints in the bitstream. This is the part most people miss. AI video exporters write specific encoder signatures into the video stream itself — Lavc (FFmpeg's libavcodec), x264 SEI (Supplemental Enhancement Information) user data, and similar marks. These aren't in the metadata — they're embedded in the compressed bitstream. Even if you strip all EXIF data, a trained classifier can detect the encoder fingerprint. This is how platforms catch files that have been "cleaned" by naive tools that only touch metadata.
Missing authentic phone-capture signals. A real iPhone 16 Pro video has Make=Apple, Model=iPhone 16 Pro, Software version, GPS coordinates, and a capture timestamp. It has an encoder name like Apple media types, not Lavc58.134.100. When platforms see a file with zero GPS, a generic encoder, and no device profile, that's a signal — not a guarantee of AI, but a factor in the scoring model.
In 2026, Instagram, TikTok, YouTube, and Reddit all run multi-signal classifiers that combine these factors. A file with C2PA atoms, XMP AI flags, an FFmpeg encoder fingerprint, and no GPS will score high on the AI-probability scale regardless of what the visual content looks like.
Calabi runs a single automatic pipeline with three stages. Upload your AI-generated file, wait about 30 seconds, download a clean file with a forensic proof card showing exactly what changed.
Stage 1 — Strip. Calabi removes every detectable AI signal. That means all JUMBF / C2PA atoms (verified down to zero), every XMP property with AI or generator semantics including DigitalSourceType: trainedAlgorithmicMedia, and the encoder fingerprints in the video bitstream. In testing, a raw AI export's 144 metadata tags get stripped down to roughly 94 neutral structural tags. The C2PA manifest — every atom and reference — is gone.
Stage 2 — Inject. Calabi writes authentic phone-capture identity into the file: a real device profile (iPhone 15 Pro, Pixel 8 Pro, Galaxy S24 Ultra, etc.), GPS coordinates, capture timestamp, and a real-phone encoder name. The device profile is consistent with how the file was supposedly captured. This isn't guesswork — it's the exact device fingerprint that platform classifiers expect from genuine user content.
Stage 3 — Verify. Every download includes a forensic proof card — the same ExifTool output that newsrooms and platform trust-and-safety teams use. You see exactly what was stripped (18 JUMBF atoms, 16 C2PA references, the trainedAlgorithmicMedia flag) and what was injected (device profile, GPS, encoder). If a platform flags your file, you have the documentation.
What about visible watermarks like Sora's sparkle or a tool's corner logo? Calabi doesn't touch visible marks — pixel editing and inpainting are outside its scope. But cropping removes the visible mark. And critically, Calabi strips the invisible detection layer — the C2PA manifest, XMP flags, and encoder signatures — that survives cropping and would still get you flagged even after you've removed the visible logo.
Can Calabi guarantee a platform won't flag my file? No tool can make that guarantee. Platform classifiers evolve, and some use perceptual hashes (p-hashes) that analyze visual content directly. What Calabi removes is the machine-readable AI detection layer — C2PA, XMP flags, and encoder fingerprints — which is what most automated systems rely on. Results vary by platform and source model.
Does this work on video and images? Yes. The pipeline handles both. Videos get bitstream-level encoder stripping; images get metadata and XMP stripping. Device profiles are available for iPhone, Pixel, and Galaxy lines.
