Thanks for the report. The screenshot confirms that a residual is visible, but the original video is required to reproduce and measure this issue because the watermark anchor, alpha profile, frame-to-frame behavior, and export encoding can differ between Gemini/Veo outputs. Please attach: (1) the original Gemini video file before cleanup, (2) the processed video downloaded from the website, (3) the video resolution and duration, and (4) the browser used and approximate test time. The current repository video regression set passes 5/5 samples with measured residual-confidence reductions of 92.4% to 99.1%, but those fixtures cannot verify this specific video. I will keep the issue open pending the original files.

The watermark wasn't completely removed; there are still some shadow-like traces left.

已用你提供的原始视频和处理后视频重新核实。

当前网站自动预设处理原始视频后，对固定水印锚点做 16 帧全扫描，残留分数均为 0.0；仓库内现有的视频回归批次也已 5/5 通过。针对相邻的 32px 小水印问题，我另外提交了 #131，但 #114 这个样本本身在现行 48px 路径上没有检测到可量化的水印残留，因此没有为它盲目增加更强的清理，避免损伤画面。

麻烦用当前网站版本再处理一次。如果肉眼仍能看到残留，请补充最明显的时间点（例如 00:03.2）以及本次新导出的文件；我会按指定帧继续核对，不需要你重复整套排查。
