SceneMixer, read against Article 50
SceneMixer (scenemixer.com), an AI short-drama generator, states a two-layer mark in its terms of service and names the rules it follows, Article 50 among them: a visible label, and an invisible watermark or content credential kept on every file. From 2 source pages, read 2026-10-13; no maker pays to be listed.
| Point | What the vendor's pages state |
|---|---|
| Article 50(2), machine-readable marking | An invisible, compression-resistant watermark or content credential, never removed |
| Article 50(4), deployer disclosure | A corner badge at delivery, on by default |
| Who controls it | Paid members, per render; the invisible layer stays |
| Stated rules for the mark | China's deep-synthesis provisions and EU AI Act Article 50 |
Inclusion rule. Points are the same four for every generator recorded here: the two Article 50 duties, who controls the mark, and whatever the vendor states about it. A point the vendor does not publish is recorded as not documented. Order. Fixed order, identical on every generator page.

2Both halves of Article 50, on one page
Paragraph 2 asks providers for machine-readable marking; paragraph 4 asks deployers for a disclosure a viewer can perceive. This entry's terms describe an answer shaped like each: an invisible, compression-resistant watermark or content credential, and a visible label, which the product pages describe as a small corner badge applied at delivery by default.
The instruments it cites are Article 50 of the EU AI Act and the Chinese provisions on deep synthesis. Few vendor pages in this record cite an instrument at all.

3What can be removed, and by whom
The visible label may be removed only as a paid option, and only where the law governing the user's own use permits it; the vendor can audit that and withdraw it. Nothing removes the invisible layer. The product's compliance guide adds the publisher's side:
Keep whatever content credentials or generation metadata the tool writes. Re-encoding or re-exporting through an editor that strips metadata removes the automatic layer, and then the visible notice is your only evidence of compliance.
SceneMixer, compliance guide
Read against paragraph 2, the two documents describe a signal meant to survive compression and a metadata layer an editor can strip, which is the failure mode the marking duty runs into.
4What is still not published
Neither a reader for the invisible layer nor a list of its fields is published, so nobody receiving a file can test for it yet, unlike the schemes elsewhere in this record that name a detector or a standard. Whether any arrangement discharges a duty is, as everywhere in this record, a question for whoever publishes the work.
5Columns filed separately for this entry
Four words is all a row holds. Where a cell read off SceneMixer's terms of service needs the sentence behind it, the kind of document that sentence sits in and the limit on what it proves, it is filed on its own page below.
- SceneMixer on a badge at delivery — A small corner badge is applied at delivery by default, and the terms present it as the visible half of a two-layer mark that names Article 50.
- SceneMixer on a switch for paid members — Paid members can switch the visible badge off for later renders; the terms make it an optional paid feature, conditional on the law and revocable.
- SceneMixer on a badge already on — The visible badge is on by default and only a paid member can switch it off, so free accounts ship a marked file, and every account the invisible layer.
