Your documentary took months — sometimes years — to create. The subtitles should reflect that same care. Hello8 combines AI speed with human precision to preserve your narrative voice in every language.
Documentary filmmaking presents subtitling challenges that generic tools aren't built to handle.
Documentaries feature real people speaking naturally — with accents, dialects, and emotional cadence that generic AI often misinterprets.
Interviews reference local customs, historical events, and cultural expressions that require careful translation to preserve meaning.
Panel discussions, crowd scenes, and overlapping dialogue need precise speaker identification and timing.
Submission windows are tight. You need fast turnaround without sacrificing the quality that judges and audiences expect.
Every feature is designed around the real needs of documentary filmmakers and post-production teams.
AI handles the initial transcription across 90+ languages. Human editors then review every line, correcting nuances that automation misses.
Translations that go beyond word-for-word. Our editors ensure cultural references, idioms, and colloquialisms are adapted for the target audience.
Automated validation checks for reading speed (CPS), line breaks, typographic conventions, and subtitle timing — per language.
Frame-accurate subtitle timing that respects your editorial rhythm. Subtitles appear and disappear in sync with dialogue and scene cuts.
