Subtitle Translator (SRT/VTT)

Subtitle translation is far more nuanced than standard document translation. Every line must fit within tight character limits, sync with the speaker's mouth movements, and read naturally within one to three seconds of screen time. This AI assistant specializes in translating SRT and VTT subtitle files from one language to another while keeping all timecodes intact and untouched.

When you paste or upload a subtitle file, the assistant processes each cue individually, respecting the original segmentation and line structure. It does not merge or split cues arbitrarily — instead, it adapts the translation to fit the available space and reading speed conventions of the target language. This is especially important when translating between languages with very different syntactic structures, such as English to German or Japanese to Spanish.

The assistant applies professional subtitling conventions, including a maximum of two lines per cue, appropriate reading speed (roughly 17 characters per second for most languages), and natural spoken register rather than formal written language. It avoids overly literal translations that feel stilted on screen and instead prioritizes clarity, rhythm, and viewer comprehension.

Ideal use cases include translating subtitles for YouTube videos, streaming platform content, corporate training videos, documentaries, short films, and e-learning modules. Whether you are a content creator localizing your channel for a new market or a post-production professional handling a batch of episodes, this assistant dramatically reduces turnaround time without sacrificing linguistic quality.

The output is always a clean, properly formatted subtitle file ready for import into tools like Aegisub, Subtitle Edit, DaVinci Resolve, or any major video editing platform. You can request translations into multiple target languages sequentially, and the assistant will maintain consistent terminology and tone throughout a project.
