Subtitle timestamp

A subtitle timestamp identifies a position on the media timeline using a format accepted by the file type.

Updated 2026-10-29 · Topicut editorial

Meaning

A subtitle timestamp identifies a position on the media timeline using a format accepted by the file type.

A practical example

SRT commonly represents a millisecond point as 00:00:02,500, while plain VTT uses a period for the fractional separator.

What to check

Do not treat a displayed clock time as a frame count. Preserve the unit and precision during conversion and test against the same recording.

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.
