Meaning
A sidecar subtitle file is a separate timed text asset associated with a video, such as an SRT or VTT file.
A practical example
A delivery package may include video.mp4 and captions.en.vtt so a receiving player can offer a selectable English track.
What to check
Matching filenames do not guarantee matching versions. Test the player association and retain which video revision the sidecar was checked against.
For a related planning or text task, open the srt vtt converter. The tool has its own limits; its result is not a measurement or approval of every concept described here.
