Rewrite an MP4 or MOV file without its metadata, keeping only allowlisted boxes.
coreav sanitize INPUT OUTPUT rewrites an MP4 or MOV file as MP4 by stream copy, keeping only the boxes on an allowlist. That drops location, device, dates and other metadata. --keep chooses what survives: by default the rotation, the languages, the gapless playback data and the track roles. The summary is coreav.remux/1, with the dropped boxes listed.
coreav sanitize upload.mp4 clean.mp4
coreav sanitize --keep none upload.mp4 clean.mp4
Rewrite an MP4/MOV file as MP4 without its metadata (location, device, dates), keeping only allowlisted boxes, without re-encoding
Usage: coreav sanitize [OPTIONS] <INPUT> <OUTPUT>
Arguments:
<INPUT> The file to rewrite
<OUTPUT> Where to write the MP4 file: a new file, or `-` for standard output
Options:
--streams <STREAM> Stream indexes to keep, comma separated (default: every stream MP4 can carry)
--fail-on-unsupported Fail instead of dropping a stream that MP4 cannot carry
--allow <CODEC> Codecs to accept, comma separated, as for `coreav probe`
--strict Reject the whole file when a stream's codec is not allowed
--force Overwrite OUTPUT if it exists (a symbolic link is replaced, not written through; the new file keeps the old one's permissions)
--keep <FIELD> What to keep, comma separated: `rotation`, `language`, `dates` (creation times), `gapless` (encoder delay and padding), `kinds` (track roles), or `none` [default: rotation,language,gapless,kinds]
