Case study

Three years of subtitling and QC for Tamil and Hindi streaming.

A streaming platform needed continuous Tamil and Hindi subtitling and QC across a growing catalog, where timing and readability are judged by every viewer, not a spec sheet.

Project overview

What landed, and what made it hard.

A streaming platform needed Tamil and Hindi subtitling and QC on a continuous cadence as its regional catalog grew, delivered through a top-100 LSP under their brand.

Why this mattered

Outcome before process.

Subtitling lives or dies on timing and readability: a late cue or an awkward line is visible to every viewer, and a three-year engagement only holds if quality survives the early feedback cycles.

The problem to solve

Why the work was difficult, and what MoniSa changed in-flight.

Continuous subtitling fails when reviewers rotate, when timing and language are checked separately, or when QC drifts as episode volume climbs.

The challenge

The problem to solve

Continuous subtitling fails when reviewers rotate, when timing and language are checked separately, or when QC drifts as episode volume climbs.

The platform needed subtitling and an independent QC pass held to one bar across three years, with the partner brand in front of the end client.

Operating response

What MoniSa changed

MoniSa ran subtitling and a separate QC lane as white-label production, with reviewer continuity and a fixed quality bar across the full engagement.

  • Separate QC laneSubtitling and QC ran as distinct passes so timing and language errors were caught before delivery.
  • Reviewer continuityStable reviewers across three years kept readability and timing consistent as the catalog grew.
  • White-label deliveryWork shipped under the partner brand, with production handled invisibly behind it.

Results

Measured outcomes from this engagement.

The platform received 3,100+ minutes of subtitling and 2,000+ episodes of QC over three continuous years, at 8.5–9 / 10 subtitling and 9.5 / 10 QC on this engagement.

Selection logic

What protected the result.

Long-run subtitling needs a separate QC lane and stable reviewers, not a bench that re-learns timing and readability each season.

Surviving the early feedback cycles and holding quality for three years mattered more than any single batch.

What buyers can reuse

What buyers can reuse

  • Subtitling quality is a timing and readability problem that only a separate QC lane reliably catches.
  • A three-year engagement is proof of sustained reliability, not a one-off pass that looked good once.
  • The evidence keeps the client and partner details confidential and attributes the metrics only to this engagement.

LLM fine-tuning evaluation

The challenge. A model team needed 20,000 prompts evaluated across 50 languages under a compressed decision window for a fine-tuning decision.

What we did. MoniSa sourced five pre-calibrated evaluators per language across all 50 tracks in parallel.

The result. The team received ~20,000 evaluations across 50 languages during the compressed sprint with reviewed quality.

Legal translation into Khmer

Problem. A global marketplace needed 250,000 words of legal content translated into Khmer for market entry.

Action. MoniSa sourced legal-literate Khmer linguists with a separate review pass and terminology control.

Result. The marketplace received 250,000 words of legal Khmer translation and review.

Multi-device subtitle QC

Problem. A media catalog needed subtitle QC verified across five device types and four languages.

Action. MoniSa ran QC against a per-device checklist with native reviewers per language.

Result. The catalog received 500+ hours of subtitle QC with reviewed quality across Mac, Windows, mobile, iPad, and OTT.
