Specification
Project requirements and deliverables.
What we need from you, how the work is reviewed, and what you receive.
| Typical inputs | Video, audio, scripts, subtitle files, metadata sheets, DTP assets |
|---|---|
| Review path | Timing QC, linguistic QC, format validation, native review, final media check |
| Strongest fit | OTT release windows, training video localization, multilingual media backlogs |
| How the work runs | Language-specific media pods with internal QA before client QA |
Quality method
Media quality is controlled through timing, language, and packaging together.
Subtitle wording is only one risk. Sync drift, metadata mismatch, and final-file failure can break the release window.
Format
Runtime, file specs, and handoff rules are fixed before the work opens.
Timed text
Subtitle and metadata checks move with language review, not after it.
Sync QA
Audio, timing, and reading-speed issues are checked in the live lane.
Version
Corrections stay versioned so the release package does not fragment.
Package
Final files are checked as a release set, not as isolated pieces.
Delivery
The buyer receives a package ready for launch review, not reassembly.

Media and metadataFixed-window OTT rare-language sprint.
OTT rare-language sprint
The challenge. A streaming team needed subtitle, dubbing, and metadata work to land for a fixed release window.
What we did. MoniSa ran parallel language pods with timing QC, linguistic review, and metadata checks before client handoff.
The result. The release package moved through timing, language, and metadata checks before client review.

Send the language list and volumeTranscriptionStanding multilingual audio transcription operation.
Audio transcription standing operation
Problem. Multiple AI-focused programs needed weekly audio transcription throughput across major and rare languages.
Action. MoniSa standardized onboarding, script-specific checklists, and reviewer feedback loops for recurring batches.
Result. The standing operation kept multilingual audio throughput moving without rebuilding the team every week.
InterpretationFull-lifecycle interpreter deployment across multiple languages.
Interpreter deployment program
Problem. An interpretation platform needed live-session interpreters who could clear sourcing, assessment, onboarding, permissions, and deployment quickly.
Action. MoniSa ran a staged interpreter pipeline with compliance checks, platform onboarding, and monitored launch sessions.
Result. The platform received interpreters who were ready for live operations rather than only language-qualified on paper.
Translation and LSP supportRare-language TEP surge across multiple languages and scripts.
Rare-language TEP surge
Problem. A technology buyer needed translation, editing and proofreading across rare languages and scripts on a tight schedule.
Action. MoniSa organized the work by language and script, completed parallel batches and included senior review.
Result. The buyer received reviewed translations with a clear route for questions and corrections.

Buyer questions
Common questions.
Is a recorded minute the same as a finished minute?
No, and conflating them is one of the most common causes of a disputed media invoice. A recorded minute measures the source audio going in, which is how transcription is priced. A finished minute measures the media coming out, which is how voice-over, dubbing and subtitling are priced. An hour of raw interview footage and an hour of finished programme are different quantities of work, so confirm which unit a quote is built on before comparing two of them.
What does subtitle QC actually check beyond the translation?
Timing against speech onset, reading speed, line length and line count, where the break falls in the sentence, whether the subtitle sits over on-screen text, speaker identification, encoding, and conformance to the receiving platform format. A linguistically flawless file still fails delivery on any one of those, which is why format validation runs before a file is sent rather than after it comes back.
Do you do proper SDH, or captions with a different filename?
SDH is specified and checked as its own discipline. Beyond the dialogue it carries consistent speaker identification, described sound effects and music, and positioning that does not obscure on-screen text, against recognised accessibility standards. If a brief says captions when it means SDH, the difference shows up at platform QC rather than in the translation.
Will you send a voice sample before we discuss commercials?
Yes — for voice work a sample should come before a rate conversation, because casting is most of the decision. For rare languages availability is confirmed first and samples follow, since there is no point discussing a rate for a voice that cannot be booked. Where a brief specifies a talent configuration, a gender, an age range or a match to the source performance, that is treated as part of the specification rather than a preference.
What audio do you deliver, and to what specification?
To the receiving specification rather than a house default: container format, sample rate and bit depth, channel configuration, loudness consistency, and naming convention, with recordings checked for background noise, distortion, clipping and breath artefacts. Where a programme requires studio capture rather than a home setup, that is agreed up front because it changes both scheduling and cost, and discovering it at delivery helps nobody.
How do you handle a fixed launch window?
By removing the failure that actually breaks release dates, which is version drift rather than throughput — a file approved against one cut while production ships another. Locking the reference cut, or versioning every asset against a named one, prevents more launch failures than adding capacity does. Translation parallelises; review, mix and QC do not parallelise as cleanly, so real compression comes from removing serial dependencies rather than from adding people.
What happens if you cannot staff one of my language pairs?
For the proposed project, ask for pair-by-pair availability or a recruitment window in writing before agreeing a date. Define qualification and pilot approval for any new contributor before live work. A coverage claim should be checkable before the scope is signed.
