SL-61 / Inclusion as Craft

Sign That Lands

Signers converse. They do not demonstrate.

The brief

A signed exchange integrated into an ongoing conversation between signers, in a named sign language, at conversational speed.

Why it's hard

Models produce hand-shaped gibberish that resembles signing without meaning anything, and crop hands at the frame edge — which in a signed language is like cutting off half the words.

The craft key

Linguistic accuracy and framing: name the specific language, keep both signing spaces whole, and have a fluent signer verify anything generated.

Every challenge is scored against the same vocabulary, so you can compare them. Lit cells are what this one tests.

Starter prompt

Built with the CEMI MediaMax system for Google Veo 3.1. Prompts stay in English — that is the language these models take instructions in. Treat it as a starting point and start varying it.

sign-that-lands

Two friends at a cafe window table mid-conversation, cool overcast daylight plus a warm pendant bulb. They are signing in American Sign Language at full conversational speed — [insert the specific signed phrase here, blocked and verified by a fluent Deaf signer before generation] — with real turn-taking: overlap on the handoff, one signing one-handed while the other hand holds a cup, a brief interruption, eye contact held throughout because gaze governs the turn. Framing keeps both signing spaces whole from hip to above the head; hands are never cropped. Table register of Hirokazu Kore-eda photographed by Ari Wegner. DIRTY FOREGROUND: a condensation-fogged window edge and a sugar shaker at the near edge. 35mm at f/2.8, handheld, reframing a beat behind the turn changes. NO demonstrating to camera, NO isolated gestures, NO dialogue text.

Why it's built this way

Signers converse; they do not perform vocabulary at the lens. The craft constraints are framing (never crop the signing space) and turn-taking behaviour (overlap, one-handed signing, sustained gaze), which is exactly where generic "sign language" prompts collapse. Always name the specific language, and never ship signed content a fluent Deaf signer has not verified.

Watch for

Hand-shaped gibberish that resembles signing but means nothing, plus cropped hands at the frame edge. Treat any generated signing as unverified until a fluent signer confirms it, and widen the frame before you re-roll.
