React 1 Talking Head — Frequently Asked Questions
How much does React 1 Talking Head cost?
It depends on resolution. A 10-second clip costs 297 credits at 720p and 436 credits at 1080p. Visualix AI prints the exact cost on the Generate button before you commit, and refunds automatically if a run fails.
How long can a React 1 Talking Head sync be?
React 1 Talking Head handles up to 15 seconds in a single pass — selectable lengths are 5s, 10s and 15s. For longer pieces, generate several shots and cut them together in the editor.
What do I need to run React 1 Talking Head?
A video containing a face and the audio track you want it to speak. React 1 Talking Head re-times the mouth to match the new audio while holding the rest of the performance and the subject's identity in place.
Can I use React 1 Talking Head in a language other than English?
Yes. React 1 Talking Head works from the audio waveform rather than a transcript, so it syncs to any language — which is what makes it useful for dubbing an existing video into new markets.
What resolution does React 1 Talking Head output?
720p and 1080p. Anything you generate can be pushed to 4K afterwards with the video upscaler.
Do my credits expire?
No. Unused credits expire at plan renewal/expiration. There is no throttled "unlimited" tier and no queue that slows down the more you use it — you see the price of each generation and pay that.
