Are subtitles just a timed transcript?

No. A transcript records everything said. Subtitles are condensed to fit reading speed and split at phrase boundaries for on-screen display.

How many characters should a subtitle line be?

For Latin scripts, 42 characters per line is the most widely used limit. Character-based scripts such as Japanese and Chinese use much lower limits because the characters are wider.

Should subtitles include speaker names?

Standard subtitles usually do not, since the picture shows who is talking. SDH does, because it assumes the viewer cannot hear.

Should subtitles match the transcript word for word?

No. A transcript records everything; subtitles condense to fit reading speed. Expect the subtitle text to be shorter than the transcript for the same passage.

What Are Subtitles?

VideoText editorial team. Updated September 13, 2026.

Direct definition

Subtitles are timed text shown with a video, usually as a toggleable track. In many locales they translate dialogue. In accessibility contexts the same file family also carries captions for viewers who cannot hear the audio.

The sections below explain how subtitles is used in transcription and subtitle work, what people often mix up, and which VideoText workflow applies when the next step is a file or review pass.

Key takeaways

A subtitle file is timed; a transcript may not be.
Language subtitles and SDH/captions can share a format (SRT, WebVTT) with different content rules.
In U.S. accessibility usage, captions include non-speech sounds; language subtitles often do not.

How subtitles are delivered

Soft subtitles travel as SRT, WebVTT, TTML, or similar. Open subtitles are burned in. Players map current time to the active cue.

Reading speed is the governing constraint

A subtitle has to be readable in the time it is on screen. That budget is expressed as characters per second, and it is the reason subtitles condense rather than transcribe: spoken language routinely outruns what a viewer can read.

Condensing well means keeping meaning and register while dropping redundancy. It is an editorial skill, and it is what separates a usable subtitle file from a transcript cut into timed chunks.

Line breaks carry meaning

Where a line breaks changes how quickly it parses. Breaking at a clause boundary reads cleanly; breaking between an article and its noun, or splitting a name, forces the viewer to re-read.

Two lines is the conventional maximum, with the upper line usually the shorter of the two unless that would break a phrase badly.
