Finding a Reviewer for an AI Translation, and Briefing Them Well

What makes someone a good reviewer

"Native speaker" is the usual shorthand, but being born into a language doesn't make someone a careful reviewer. Look for these qualities, roughly in order of importance:

1. Fluency in the target language, as spoken by your audience. A Spanish speaker from Spain reviewing a video for Mexican viewers will make different choices than one from Mexico.
2. Ability to read the source language. A bilingual reviewer can compare the translation with what was said and catch meaning errors. A reviewer who reads only the target language can judge naturalness but can't tell you if a sentence says the wrong thing.
3. Knowledge of the subject. Someone who knows the field catches terminology errors a generalist misses.
4. Writing skill. Good reviewers propose fixes that read well, not just "this sounds off".
5. Reliability. They read everything, including the boring middle, and deliver when they say they will.

If you can't find all of that in one person, split the job. A bilingual reviewer checks meaning, then a monolingual native reader checks that the result sounds natural. That two-pass approach mirrors how professional localization separates review from proofreading.

Where to find reviewers

Each source has strengths and blind spots:

• A bilingual colleague knows your product and your audience and is easy to reach. But reviewing isn't their job, so it gets squeezed, and colleagues tend to be polite about each other's work. Ask a manager to make the time official.
• Someone from your audience, such as a viewer, customer, student's parent or community member, knows exactly how your viewers talk. Reliability varies, confidentiality needs thought, and it is fair to offer something in return, whether payment, credit or a free product.
• A freelance reviewer or translator is trained to review, and has the time if you pay for it. National translators' associations often publish member directories, and general freelance marketplaces list reviewers by language pair. Check samples and ask about subject experience.
• A professional translator or agency is the right choice for medical, legal, financial and safety content, where errors have real consequences.

The question of when AI plus review is enough versus when to hire translators from the start is covered in AI vs human video translation.

What to send them

A reviewer who only gets a subtitle file can't see who is speaking, what's on screen or how the voice sounds. Send a complete package:

The video

The original, so they can see context and on-screen text

Translated subtitles

The SRT file in the target language, which opens in any text editor or subtitle editor

Translated transcript

Easier to read straight through than subtitle cues

Source transcript

Timestamped, so a bilingual reviewer can compare line by line

Dubbed version

If you made one, so they can check the voice, pacing and pronunciation

Glossary

Names, product terms and the do-not-translate list

Style guide

Register, numbers, region; see creating a translation style guide

The brief

One page saying what to check and how to report it

Name files clearly with the video title, language and version, so feedback refers to the right edition.

A review brief template

The brief is what turns "can you have a look?" into feedback you can use. Keep it to one page:

1. About the video: what it is, who watches, where it will be published, and the target region.
2. What the translation is: an AI draft, not yet edited by anyone.
3. What to check, in priority order: meaning against the original, names and terms against the glossary, numbers, register, then naturalness.
4. What not to change: the do-not-translate list, and any decisions in the style guide.
5. How to report: edit the SRT directly and list changes with timestamps, or leave comments by timestamp in a shared document.
6. How to separate errors from preferences: mark each note as "wrong" or "could be better".
7. Scope: full review, or meaning-only, or one specific section.
8. Timing and payment: deadline, rate or fee, and how to invoice.
9. Confidentiality: whether the video is unpublished and who they may share it with.
10. Contact: who answers questions while they work.

Item 6 matters most. Without it, a reviewer's personal style and genuine errors arrive mixed together, and you can't tell which changes are essential.

How much time and money to plan for

Review takes longer than people expect, because a careful reviewer watches the video, reads every line against the original, looks things up and writes notes. Avoid estimating from the video's length alone. Ask the reviewer for an estimate after they have seen the material, or send a two-minute sample first and ask how long it took.

Freelancers commonly charge per hour, per word or per minute of video. Ask for a quote on your actual file. For volunteers and colleagues, protect their time by keeping the scope tight: a meaning-only review of the parts that matter most is better than a full review that never gets finished. Budget for a short second look after you apply their changes, which is quicker than the first pass.

Handling feedback without endless rounds

1. Sort the notes. "Wrong" notes are fixed. "Could be better" notes are checked against your style guide and accepted unless they conflict with it.
2. Ask about anything you don't understand. A one-line "why?" often reveals a regional or terminology issue worth adding to the glossary.
3. Update the glossary and style guide with any new decision, so the next video doesn't repeat the problem.
4. Apply the changes to the subtitle file. For a dub, changed lines need replacing in an editor, because editing text doesn't change the recorded voice.
5. Send back only the changed lines for a quick final check.
6. Thank the reviewer, and credit them if they want to be credited.

Resist sending the same translation to a second reviewer to settle disagreements, unless the content is high-stakes. Two fluent people will always phrase things differently, and the rounds never end. For editing the draft yourself, machine translation post-editing explains how deep to go.

Mistakes that waste a reviewer's time

• Asking "does this look OK?" without saying what to check or what kind of feedback you want.
• Sending only the SRT, so the reviewer can't see the speaker, the screen or the context.
• Reviewing after publishing. Changes are slower and more visible once a video is live.
• Using one reviewer for several regions, such as one Portuguese speaker for both Brazil and Portugal.
• Ignoring confidentiality. Share unpublished material only with people who need it, and ask freelancers to agree to confidentiality where that matters.
• Not paying, or paying in "exposure". Good reviewers are skilled people, and goodwill runs out.

Getting review files out of mydubly

mydubly produces the files a reviewer needs: a timestamped transcript in the spoken language, subtitles as SRT and VTT, an optional translated transcript, and for dubbing, the translated voice track (M4A) and translated video. Each subtitle job produces one language, so run the file once per language you want reviewed.

Review itself happens outside mydubly; there are no built-in sharing, commenting or editing tools. Audio and results are deleted within 30 minutes of completion, so download everything you need and store it yourself before sending it to a reviewer. For the 8-minute training video in the example, subtitles in one language cost 8 credits (0.8¢) and a dubbed version costs 400 credits (40¢). The video translator and AI dubbing pages describe both outputs, and the AI dubbing quality checklist gives reviewers of a dub a list to work through.

Next step

Write the brief before you look for a reviewer. Having it ready makes the request concrete, which makes people more likely to say yes, and it turns the first review into a reusable process. If more than one person will touch each video, the roles and handoffs are covered in video translation review workflow for teams, and training-specific advice is on the training video translation page.
