`video visible` and `remove_video_visible` additionally support the moving

Detection requires a recurring visual candidate across adjacent frames.
Seedance, Dola, and Veo candidates must remain anchored rather than drifting
with a scene object. Provider provenance can recover low-contrast runs only

MINIMAX/Hailuo composite label, and the bottom-right Kling label with its
version suffix. Detection requires a recurring visual candidate across
adjacent frames. Fixed-mark candidates must remain anchored rather than
drifting with a scene object. Kling also requires a bright low-saturation
candidate near the expected frame edge. Provider provenance can recover
low-contrast runs only after visual evidence exists for the marks that define a
provenance prior, so metadata alone does not erase a clean API export.
Historical Sora Turbo exports use a small OpenAI swirl in the corner rather
than the moving mascot-and-wordmark design; that earlier variant is not
detected by the `sora` video mark. Other provider video labels are not

`moov.udta.meta.keys/ilst` placement, including non-faststart files whose
`moov` follows a large media payload. MKV/WebM is supported at the normative
`Segment.Tags.Tag.SimpleTag` placement and uses ffmpeg for stream-copy removal.
The corresponding FLV and AVI native tags are not parsed yet.
AVI is supported at `LIST/INFO/AIGC`, and FLV at
`script.onMetaData.AIGC`; both use ffmpeg stream-copy removal. Stock ffmpeg can
write and strip the FLV form, but writing the nonstandard AVI child for fixture
generation requires dedicated muxer support, so the AVI reader is verified
against an exact synthetic RIFF structure.
The current ISOBMFF stripper reads an MP4, MOV, or M4V container into memory
before rewriting its metadata boxes. A streaming box copier is required before
