Help & FAQs
Everything you need to know about AI video translation.
We utilize advanced neural machine translation combined with context-aware AI models. Octavia doesn't
just translate words; it understands context, idioms, and cultural nuances. Our voice cloning technology
preserves the original speaker's tone, emotion, and speaking style. Every translation is processed
through multiple quality checks, and you can preview and adjust any output before finalizing.
Absolutely. Octavia supports videos up to 10 hours in length and files up to 5GB. Our distributed GPU
processing network handles long-form content efficiently, processing hours of video in minutes. We
support all major formats (MP4, MOV, AVI, MKV) and automatically optimize your content for the best
translation quality. For enterprise clients, we offer unlimited file sizes and custom processing
pipelines.
Privacy is our top priority. All uploads are end-to-end encrypted during transfer and storage. Your
videos are processed in isolated, secure containers and automatically deleted after 30 days (or
immediately upon request). We legally guarantee that your content is never used to train our public
models or shared with third parties. For sensitive content, we offer on-premise deployment options where
data never leaves your infrastructure.
Our lip-sync technology uses advanced computer vision and audio analysis to match mouth movements with
translated audio. The AI analyzes facial landmarks, phoneme timing, and speech patterns to ensure
natural synchronization. It works across different languages with varying syllable counts, automatically
adjusting timing and pacing. The result is dubbed video that looks and sounds like the speaker is
naturally speaking the target language.
Yes. Our multi-speaker diarization automatically identifies and separates different speakers in your
content. Each speaker gets their own voice clone in the translated version, maintaining the natural
conversation flow and individual vocal characteristics. This works for interviews, panel discussions,
podcasts, and any content with multiple speakers. You can also manually adjust speaker assignments if
needed.
Octavia excels at technical content. Our AI models are trained on specialized terminology across
industries including medical, legal, technical, and scientific fields. You can upload custom glossaries
to ensure brand names, product terms, and industry-specific jargon are translated correctly. For
enterprise clients, we offer domain-specific fine-tuning to match your exact terminology and style
guidelines.
Yes, with our Pro plan. Upload a 30-second to 2-minute sample of your voice to create a custom voice
profile. This allows Octavia to generate translations in your exact voice across any language. The AI
preserves your unique vocal characteristics, speaking style, and emotional range. You can create
multiple voice profiles for different speakers or use cases, and all voice data is stored securely and
never shared.
that feels familiar and natural to you. Alternatively, choose from our library of 50+ premium AI voices
optimized for different languages and content types.
Your content belongs to you. If you choose to cancel, you can export all your translated videos, audio
files, subtitles, and transcripts in a single click. We believe in zero lock-in. Your account will
revert to the Free tier where you can still access your existing projects, but new translation limits
will apply. All your data remains accessible and exportable at any time.
