Two files, one episode?
Split episodes and double-disc releases need their captions joined back into a single file. Simple concatenates the two files, nearest combines cues that sit within a gap so captions don't jump, and glue shifts the second file by the first one's duration so CD2 starts right where CD1 ended. All processing is client-side — nothing is uploaded.
