Why mSUBS

Your story travels only as far as your audience can follow it.

A viewer who can't follow the dialogue is gone in seconds, and a caption that mistimes or mistranslates loses the very market you were trying to win. mSUBS exists so language is never the reason your content stops at a border.

The pipeline

AI for speed. Native linguists for trust.

Five steps from master file to delivery, every one designed so volume never costs you accuracy or compliance.

Steps 03–04 are MTPE

MTPE, Machine Translation Post-Editing, is a hybrid translation process: a machine translation engine produces a raw first draft, and a native linguist reviews and refines it for meaning, tone, and timing. It's the discipline behind Translate and Verify above, AI for coverage, humans for accuracy.

Accessibility & compliance

Captioning isn't optional. Neither is getting it right.

Regulators and platforms mandate accurate captions, and penalise the gaps. mSUBS builds compliance into the pipeline, with native-linguist QC on every deliverable, so accessibility is a guarantee, not a hope.

The discipline

Subtitles translate. Captions include. mSUBS does both.

Localization is no longer a post-production afterthought, it's the difference between a regional asset and a global one. mSUBS turns one master into every market's version, fast enough to ship day-and-date.

Subtitles carry meaning to viewers who hear but don't speak the language. Captions transcribe every sound, dialogue, speaker, effect, for accessibility and compliance. Both demand timing, terminology, and cultural nuance a raw model can't be trusted with alone.

The bigger picture

Localization is one move in a longer content lifecycle.

mSUBS adapts content across languages. Infoesearch also understands it through media intelligence and protects it through trust & safety, one continuous lifecycle, one operating company.
