Why is the translation wrong or low-quality?

Prerequisites

Translate is returning some text.

Steps

1. 1

   Fix the source

   • Tighten the zone on a clean hardsub line.
   • Match OCR language to the script on screen.
   • Use Show hardsub in Translate mode to compare source and translation.
2. 2

   Try another engine

   • Hosted Microsoft vs DeepL vs Google can differ by language pair.
   • BYOK quality is still capped by whatever that provider returns.
