Decision guide
Still deciding? Start with these key decision points.
1
When per-second cost and seed matter
Infinitalk exposes 480p/720p and `seed`, and its total changes with audio duration. It is the workflow to test when each segment needs a calculated budget before submission.
2
Billing method
The charge uses the signed audio duration at 8 credits per second and rounds up. A missing, invalid, or over-5-minute duration cannot be submitted. The charge uses the signed audio duration at 16 credits per second and rounds up. A missing, invalid, or over-5-minute duration cannot be submitted.
3
Minimum validation path
Prepare 1 supported portrait image, 1 supported audio file no longer than 15 seconds, and a non-empty prompt. Check the combination at 480p before deciding whether to rerun it at 720p.

Real-world experience
Practical guidance based on public sources, current on-site limits, and representative tasks.

480p costs 3 credits per second and 720p costs 12. The 720p rate is four times the 480p rate for the same audio, so compare the full duration total before submitting.
Split content longer than 15 seconds first
Longer narration must be split and edited after generation.
