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. A senior compositor (2026-06-07, Artlist-sponsored, Seedance 2.0) shows a hybrid VFX pattern: upload the plate as a video reference and lead the prompt with "preserve the clip 100%" (or "preserve the clip's motion 100%") then state one change: add sharks around a surfer; a shark attack; remove a black Porsche; replace it with a golden Lamborghini; collapse buildings with "realistic debris simulation, dust interaction, high dynamic range, grounded physics"; a meteor strike; relight to night and add a spacecraft (reflections in a lake were handled plausibly). Each clip took about 2 minutes; expect several takes (one take changed the camera angle, one mis-timed the action)...

Each clip took about 2 minutes; expect several takes (one take changed the camera angle, one mis-timed the action). Tips: generate multiple variations and composite the best parts with masks in a compositing app; to get alternate coverage, ask for a different angle ("create a drone shot of the scene") from the clip, or iterate a single exported still for tighter control and then animate it; for product shots, relight a phone photo into a studio look ("use the input image as the exact base; preserve the object") and use it as the start frame. Same "preserve then change" pattern as Gemini Omni Flash (C3-B335-03).

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.

Limitations: Creator statements were read by discovery from auto-captions (ASR); not re-verified by the curator. Sponsored; plate rights and AI disclosure obligations not discussed; failure rate not quantified.

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