THE SHORT ANSWER

An AI dubbing pilot is a paired test: the same clips through the current workflow and the candidate, judged by native reviewers on words, voice, scene, face, and timing, against acceptance criteria written before anyone listens. It runs on connected episodes, includes one late edit, counts revision cycles, and checks the files at release spec: 4K, true 5.1. Familiar publishes paired results; the pilot checks them on the buyer's footage.

THE SHORT VERSION

A pilot is paired: the same source clips go through the current workflow and the candidate, in two or three target languages.
Acceptance criteria are written before anyone listens: one pass mark per dimension, six measured dimensions plus three operational rows.
Native reviewers score blind where the format allows it and mark the second immersion broke.
The review step counts corrections: how many translated lines the reviewer changed before render, and of which class.
Three operational checks ride beside quality: revision cycles per episode, the time from a source change to an approved replacement, and delivery at release spec (4K picture, 5.1 mix).

01.What is a pilot for?

A demo shows the vendor's best clip. A pilot shows the buyer's hardest footage through two workflows.

The unit is a decision. The pilot answers whether a season, a catalog, or a creator network can move; one clean scene says nothing about episode sixty.
The pass mark comes first. Criteria fixed before anyone listens cannot drift toward the dub the room liked.
The design is published. Familiar's paired studies at /benchmark use it; the pilot re-runs it on the buyer's own clips.

02.Which footage goes in?

A connected run, for a series. Two or three consecutive episodes with a recurring lead, so voice, names, and honorifics are tested across the run.
The scenes that break dubs. Fast dialogue, a joke, an emotional turn, proper names, music under speech, and two or three people on camera talking over one another.
One late edit. A changed line or a re-cut scene submitted after the first dub; a changed source is a new dub request, checked at the review step.
Two or three priority languages, from the three published quality tiers at /docs/languages, best tier first.

03.What do the acceptance criteria say?

One question a native reviewer answers per clip, one pass mark per dimension, and the metric Familiar's benchmark uses for it.

TABLE 01 · THE SCORECARD · SIX MEASURED DIMENSIONS + THREE OPERATIONAL ROWS · PASS MARKS FIXED BEFORE THE FIRST RENDER
DIMENSION	THE REVIEWER'S QUESTION	FAMILIAR'S BENCHMARK MEASURES
Spoken meaning	Does the line say what was said? A native speaker or a back-translation checks it.	Important translation errors per output, against one approved target meaning
Voice cloning	Eyes closed: is this the same person?	Speaker resemblance to the real speaker
Scene audio	Are the music, the laughter, and the room still there under the new speech?	Background-sound error against the source scene, in dB
The face	Do the mouth and the whole face match the new words, on every speaker on camera?	Judged on the paired listening examples; the audio measures do not score it, and audio-only tools skip it
Vocal events and timing	Do laughs, sighs, and reactions land where and how they landed?	Event shape correlation; transient-timing F1
Coverage	Did the tool accept every clip, at every length, in every language asked for?	A rejected clip scores zero on that clip; length minimums and batch caps count against it
Revision cycles	How many passes before each language was approved?	Not in the benchmark; counted per episode in the pilot
Time to an approved replacement	How long from the late edit to an approved replacement dub?	Not in the benchmark; timed once, on the late edit
Delivery spec	On the 4K master, does each language come back at release spec: 4K picture, 5.1 mix?	Not in the benchmark; checked once per language on the finished files

A pass mark is a number. Zero translation errors on names and numbers; the speaker recognized with eyes closed by three of four reviewers; no scene where the music drops out; one revision cycle per episode.

04.How is it run?

Paired and black-box. Each source clip and target language goes through both workflows, and only the finished dub is judged, as in the published method.
Blind where the format allows it. Preference scores drift toward whatever sounds familiar; the record that holds is the second immersion broke, and what broke it.
A target-language panel beside the in-house reviewers. Outsiders catch slang, register, and a late joke; the in-house side catches a name or a house term.
The review step is the correction counter. The pipeline pauses for the reviewer: any translated line is edited at the review step before render, and the number and class of edited lines is a quality measure.
Tag every changed line. The classes show what a Do Not Translate list and a one-sentence context brief would have prevented on the second run.

05.How are the results read?

A gain counts when it holds across footage types and languages; a musical scene or a fast-cut sequence may need its own threshold.

Report footage types as separate rows. Clean single-camera scenes and fast-cut scenes averaged together hide the row that decides the catalog.
Report per language. A gain in two of three languages is a two-language contract until the third is re-tested.
Count the operational rows. Revision cycles per episode and time from a source change to an approved replacement decide whether a daily release schedule holds; delivery at release spec decides whether each language ships without a remix.
The published numbers are the reference; the pilot is the proof. Familiar's results on the same dimensions:

06.From pilot to contract

Access is by Studio contract, sized to the catalog and delivered at release spec (4K picture, 5.1 mix), with 30 day money back on signed annual contracts; the pilot's languages become the contract's first languages.

The corrections carry over. Names and phrases fixed in the pilot persist in the Do Not Translate list and context brief at the creator scope.
Live sessions are experimental and coming soon: when a contract enables them, the team sets them up (languages, expected concurrency, a rehearsal on the buyer's setup over SRT, RTMP, or WHIP); broadcasts are designed to run behind the original, every speaker in their own voice.
The sibling playbooks pick up from here: studios, streaming platforms, micro-dramas, multi-country launches, and creator networks.

QUESTIONS

How long should an AI dubbing pilot take?

Long enough to dub a connected run in two or three languages, review it with native speakers, and process one late edit. Two or three consecutive episodes with a recurring lead test continuity as well as quality.

What should a dubbing pilot measure?

Six dimensions, each scored by a native reviewer against criteria written before anyone listens: spoken meaning, voice, scene audio, the face, timing, and coverage. Three operational rows ride beside them: revision cycles per episode, time from a source change to an approved replacement, and delivery at release spec (4K picture, 5.1 mix).

Should reviewers know which dub is which?

Blind where the format allows it. Preference scores drift toward whatever sounds familiar, so the useful record is the moment immersion broke: the timestamp, and whether a joke, a name, a voice, or two people talking at once broke it.

Can the review step be part of the pilot?

Yes. Familiar's pipeline pauses at a review step where any translated line is edited before render; the number and kind of lines the reviewer changes is a quality measure, and the corrections ship in the finished dub. Live dubs (experimental, coming soon) will translate on the fly, with no review step.

What does Familiar publish for the same dimensions?

Paired studies, August 2026. ElevenLabs Dubbing v2 (Alpha) had 270% more background-sound error: the laughter, the music, the ambience. Familiar sounded 27.8% more like the real speaker than ElevenLabs Dubbing v1, closer in all 11 languages. Familiar's translations matched the first-pass expert professional at 100.3% across French, Chinese, Hindi, and Indonesian.
