…lidate clips client-side Reference media (images, video, audio) is refused by the wallet gateways since blockrun#728 / blockrun-sol#374 and served only by api.blockrun.ai. SEEDANCE_CAPABILITIES.md described it as live on all three gateways behind R2V_ENABLED, which is no longer true, and documented gateway internals and other repos; the SDK-facing parts move into the README video section. - Validate referenceVideos / referenceAudios per field with specific errors, and mirror the gateway's "reference audio needs an image or video" rule so it fails before the 402. - TSDoc: account-API-only note, per-model gating of the output controls, last_frame_url on returnLastFrame, content[] roles on generateFromContent. - README: output controls example and a reference-media section. - CHANGELOG: Unreleased entry. - Tests for each client-side refusal.

Expose typed video/audio references and output controls, allow 30 images on Seedance 2.5, and map the supported camelCase controls in both generate and generateFromContent. Retain frame/reference validation and expose last-frame response fields.
Validation
9 video unit tests passed; TypeScript checking, ESLint, CJS/ESM/declaration build, and git diff checks passed.
Rollout and limits
This PR does not deploy or change
R2V_ENABLED. Existing production 503s caused by an explicit off switch require a separate controlled enablement. Publish client changes after the gateway changes are deployed.No new paid upstream renders were performed. New request/response behavior is validated against the captured public upstream parameter schema and mocked contract/payment tests; perform a small paid render smoke test before production enablement. Automatic duration, editing/extension, 2.5 reference video/audio and 1080p, callbacks and draft/flex remain held pending cost/output or lifecycle validation.
