Original sample: unchanged.
Modification: Modified by videowatermarkremover.app on 2026-10-22: native FFmpeg with site delogo defaults at x=572,y=1132,w=56,h=56; H.264 re-encode and audio copy. Not an AI or upstream reverse-alpha result. Original is an MIT project test sample; Google generation origin is not authenticated.
Native FFmpeg used the site's current free filter and encoding recipe. No AI service was called. Source generation model/prompt and invisible provenance were not independently verified.

Reproduction: node scripts/build-gemini-sparkle-case.mjs <reviewed-20260615-3.mp4> <upstream-LICENSE>
The script verifies both source and license SHA-256 before processing, calls the site's actual op.build(), and records the precise filter, dimensions, audio payload hash and all media file hashes.
