What provenance metadata does PrismPoster embed in my files?
Every file you export from PrismPoster carries an always-on, machine-readable provenance mark written into the file's metadata. For images this lives in the IPTC, XMP, and EXIF fields; for video and audio it's written through FFmpeg metadata; for audio it's also in the ID3 tags; and the stored object carries provenance in its R2 object headers. This mark sits alongside the visible "AI-generated with PrismPoster" label and travels with the file. It is never gated by plan tier. It's on for Free, Creator, Pro, and Apex, and there is no way to turn it off.
What is provenance metadata?
Provenance metadata is a machine-readable signal embedded in the file itself that records that the content was produced with an AI tool. Unlike the visible label, which a person reads on the rendered export, the metadata is read by software, platforms, and verification tools that inspect a file's tags. Both signals are written at export time so disclosure stays attached to the file wherever it goes.
Which metadata fields does PrismPoster write?
The fields depend on the file type:
- Images carry the provenance mark in IPTC, XMP, and EXIF fields.
- Video carries it through FFmpeg metadata written into the container.
- Audio carries it through FFmpeg metadata and ID3 tags.
- Stored objects carry provenance in their R2 object headers.
This covers exports from Image Studio, Magic Edit, Video Studio, and Music Studio, at all resolutions including 4K.
Is the machine mark ever gated by plan?
No. The machine-readable provenance mark is never gated by plan tier. This is a deliberate part of how PrismPoster aligns to the EU AI Act Article 50 machine-marking requirement: the signal has to be present on all AI output, so it can't depend on what you pay. The visible label is mandatory on every plan too.
Is this the same as C2PA Content Credentials?
No. PrismPoster's provenance is metadata-based, not a cryptographic C2PA Content Credentials signature. C2PA signing cryptographically binds provenance to a file so it can be verified and detect tampering; PrismPoster does not implement that today. What you get is embedded metadata in standard fields (IPTC, XMP, EXIF, FFmpeg, ID3) plus a visible label. If a platform or tool strips a file's metadata on upload, the embedded mark can be lost even though the visible label remains part of the rendered export.
Frequently Asked Questions
Will the metadata survive after I upload my file somewhere?
It depends on the destination. The embedded mark stays in the file as long as the metadata is preserved, but some platforms re-encode or strip metadata on upload, which can remove it. The visible label is rendered into the export itself and is not affected by metadata stripping.
Can I see the provenance metadata myself?
Yes. Any tool that reads file metadata can show the relevant IPTC, XMP, EXIF, FFmpeg, or ID3 fields. The mark is written in standard fields rather than a proprietary or hidden format.
My export looks like it's missing the AI mark — what should I check?
See missing AI badge for troubleshooting. If the visible label or metadata genuinely seems absent on a fresh export, contact support@prismposter.com.
Does the metadata add cost or use credits?
No. Provenance metadata is part of every export at no extra credit cost. See how credits work for what does consume credits.
