`remove_video_visible` scans the complete video before writing output. It
combines synthetic multi-scale visual matching with temporal consistency, so an
isolated lookalike in one frame is not enough to authorize inpainting. The
supported `mark` values are `sora`, `veo`, `seedance`, `dola`, `hailuo`, and
`kling`. The Veo detector recognizes the current four-point diamond and the
isolated lookalike in one frame is not enough to authorize inpainting.
`mark="auto"` is the default: it evaluates all providers in one decode pass and
selects the first stable match in specificity order (`sora`, `veo`, `seedance`,
`dola`, `hailuo`, `kling`). Provider confidence values are calibrated
independently and are not compared across detectors. Pass one of those explicit
values to restrict the scan to a single provider. The Veo detector recognizes
the current four-point diamond and the
legacy `Veo` text. Seedance recognizes the boxed `AI` label, Dola recognizes
its compact text label, Hailuo recognizes the composite MINIMAX/Hailuo label,
and Kling recognizes its bottom-right logo, wordmark, and version suffix. Each
variant has an independent synthetic silhouette and calibrated temporal policy.
The returned `VideoVisibleResult` records the total, detected, and removed frame
counts plus any AI metadata that survived the output encode. The function
returns `output=None` and writes no file when no stable mark is selected. Video
pixels are transcoded through ffmpeg while the source audio stream is copied.
The returned `VideoVisibleResult` records the selected `mark`, the total,

stable mark is selected. Video pixels are transcoded through ffmpeg while the
complete source audio stream is copied. A failed encode preserves any existing
output; only a completed result is published atomically.
