Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. R2 (Apr 2026): lyrics drafted with an LLM, song made in Suno v5.5 with a structured prompt (concept, voices, chorus/outro, BPM, language) and "exclude styles" used as a negative prompt. Characters: character sheets, then many photos per character (33, 41 and 57) to train a custom character model on the host platform. Lip-sync shots framed as close wide-angle (8 mm-style) singing-to-camera. Key failure: when the full mix is uploaded, Seedance lip-syncs instruments too, and it can alter or invent lyrics in the audio track; fix by exporting Suno stems (Pro tier) and uploading the vocal stem only, then running a separate lip-sync pass with the same vocal stem.

Characters: character sheets, then many photos per character (33, 41 and 57) to train a custom character model on the host platform.

Key failure: when the full mix is uploaded, Seedance lip-syncs instruments too, and it can alter or invent lyrics in the audio track; fix by exporting Suno stems (Pro tier) and uploading the vocal stem only, then running a separate lip-sync pass with the same vocal stem. Dance shots cannot follow the beat reliably - generate several takes and pick on-beat moments in the edit; assemble by laying the music track first, placing lip-sync shots against their lyrics, then filling gaps with B-roll. Rights note: commercial use of Suno output depends on plan and terms (C3-B411-01).

Curator qualifications: Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. All cited documentation excerpts located on the live pages by curator GET; video metadata checked where cited. Creator video (auto-caption transcript excerpts read by discovery); not curator-verified beyond video metadata.

Limitations: Creator statements were read by discovery from auto-captions (ASR); not re-verified by the curator. Affiliate content; single project; Suno stems tier claim not checked; "train some kind of Laura" refers to a platform character-training feature whose name/terms were not identified.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
