 In cases where this particular source frame has to be dropped,

+@item scd_metadata
+If the argument is @code{scd_metadata}, ffmpeg will force a key frame if
+the current frame contains a metadata entry with the key @code{lavfi.scd.time}.
+The metadata can be added by filters like @code{scdet} and @code{scdet_vulkan}.
+Avoid inserting filters that duplicate frames after @code{scdet}, as this can
+cause duplicate metadata for multiple frames and repeated insertion of key
+frames.

 Note that forcing too many keyframes is very harmful for the lookahead
