 `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` and `veo`. The Veo detector recognizes the
-current four-point diamond and the legacy `Veo` text with separate synthetic
-silhouettes.
+supported `mark` values are `sora`, `veo`, `seedance`, and `dola`. The Veo
+detector recognizes the current four-point diamond and the legacy `Veo` text.
+Seedance recognizes the boxed `AI` label, while Dola recognizes its compact
+text label. 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
