How it works for Portuguese

Upload an English .srt or .vtt file, or a season as a zip. Cues travel to the model in batches of 32 so a sentence that spans two cues is translated as one thought. Every Portuguese cue then passes thirteen structural checks; whatever fails goes back with the exact complaint attached, and an editor pass sweeps the whole file for register and idiom. You download the subtitles and a quality report, and the upload is deleted.

What the Portuguese profile checks

• The profile is Brazilian. Its baseline was scored against a pt-BR reference, because scoring Brazilian output against a European reference would understate it.
• Explicitly instructed never to calque from English or Spanish, the two languages a model most readily borrows from when writing Portuguese.
• Same-alphabet guard: 49 Portuguese function words required, 35 known intrusions blocked.
• Scored 48.59 chrF++ against a human translation of four episodes.

Sound labels, from the table

Labels for the deaf and hard of hearing are resolved from a fixed Portuguesetable before the model sees the text, so they are never invented. Three entries, exactly as the table renders them:

[LAUGHS]

[RI]

[DOOR CLOSES]

[A PORTA SE FECHA]

[PHONE RINGS]

[O TELEFONE TOCA]

Is Portuguese measured?

Portuguese has a measured baseline: 48.59 chrF++ against a professional human translation, over 1,997 aligned units. That figure is what every change to the pipeline has to beat for Portuguese. It is not comparable to another language's figure; here is why.

Price and time

One credit translates about 20,000 characters of dialogue, roughly a 25-minute episode; a feature film is about three. Credits are $1.25 each in packs, the first episode is free, and there is no subscription. An episode takes a few minutes; you get an email when it is ready.
