Subtitle Translator

Translates SRT subtitle blocks by language pair, preserving timecodes and the numeric sequence. It is used by video editors, localization teams, and content creators who publish multilingual captions. It solves the problem of exporting translated subtitles without re-syncing with video timelines, ensuring captions stay aligned with audio.

Core concept: parse SRT into blocks with indices, time ranges and text lines; translate text segments with a machine translation backend; optional glossary guidance; reassemble translated blocks while preserving timing and line breaks; supports multiple languages and optional source language detection.

Unique value: glossary enforcement, UTF-8 encoding handling, and export as SRT or VTT; robust handling for malformed inputs; batch translation for large subtitle sets; designed for localization teams and independent creators.

Use cases: translate existing videos, produce multilingual captions, or export translated subtitles for publication across platforms; outputs are ready for direct ingestion by video players or subtitle workflows.
