A subtitle is the on-screen text representation of spoken dialogue, narration, or relevant audio information, usually displayed at the bottom of a video frame and synchronized with the original sound. In translation and localization workflows, subtitles are delivered as timed text units that must respect constraints such as reading speed, character limits, shot changes, and natural line breaks while conveying the source message accurately.
Subtitles appear in audiovisual localization projects such as feature films, streaming content, e-learning modules, training videos, and marketing clips. Translators usually work in subtitle editors or CAT tools that import SRT, VTT, or similar timed text files, editing entries against timecodes while applying the client's subtitling conventions and reading-speed limits.
A common error is treating subtitles as full written translation, producing lines that are too long or too fast for viewers to read comfortably. This often happens when character-per-second limits, reading pauses, and shot changes are ignored; the result can be unusable subtitles that break timing, fail client QA, or force costly rework.
For creative and consumer content the failure mode is flatness, not inaccuracy — and flatness passes an accuracy check. Terms here also carry technical constraints (reading speed, character budgets) that are part of the brief.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
