FAQ

Questions? Answered.

How does the AI dubbing work?
Your video audio is transcribed with AWS Transcribe, translated with AWS Translate, and a new voiceover is synthesized using AWS Polly neural voices. The final video is rendered with AWS MediaConvert. The entire pipeline is serverless, running on AWS Lambda.
Does the AI voice sound natural?
We use AWS Polly neural voices — high-quality, natural-sounding speech. It's ideal for YouTube, TikTok, educational content, and corporate videos. A premium tier with studio-grade voices is on the roadmap.
What video formats are supported?
MP4, MOV, MKV, AVI, WebM. Upload up to 5GB or provide a direct URL. Output is MP4 (H.264/H.265), up to 4K on Studio plans.
How long does processing take?
A 10-minute video typically processes in 3–5 minutes. Depends on video length, resolution, and number of target languages. You get an email when it's done.
Is my data secure?
All videos are stored in S3 with server-side encryption. Processed in your AWS region. Never shared with third parties. Delete anytime. GDPR compliant.
Can I edit the translation before rendering?
Yes. After transcription and translation, you can review and edit both the transcript and translated text before the final video is rendered. Full control over output quality.
Do you offer an API?
Yes, API access is included in the Studio plan. Integrate Cult.lat into your video production workflow, CMS, or automation pipeline. Full REST API docs in the dashboard.
What happens if I run out of minutes?
You can buy additional minutes at $0.15/min on Creator and $0.10/min on Studio. Or upgrade your plan anytime. Unused minutes don't roll over.
