Accurate lip sync
Every frame is driven by the voiceover itself, and each clip is waveform-checked before delivery.
AI talking videos
Turn one photo into a talking video
Upload a portrait, type what they should say and pick a voice. SakuVideo renders a lip-synced video with natural expressions — in your language.
Three steps to your first video
- 01
Add a photo
Any clear portrait works — a selfie, a studio shot or a product host. We keep the whole frame and never crop the person.
- 02
Write the script
Up to three minutes in English, Chinese and more. Pick a studio voice or speak in your own.
- 03
Generate
We voice it, design subtle expressions, render it, and stitch long scripts into one seamless video.
Built for creators and brands
Natural studio voices
Browse a voice library across languages, with free samples to listen to first.
Your own voice
Record 5–30 seconds and speak any script in your voice — always with your explicit consent.
Three visual modes
A single photo, a person composed into a background, or a two-camera cut.
Up to 3 minutes
Long scripts are split at natural pauses and joined into one continuous video.
Timed captions
Burn in word-timed captions if you like — a clean master is always kept.
