≈ marks a fractional rate rounded to two decimal places for display; billing uses full precision.
The dollar price follows the current coin rate.

Who makes HeyGen Video?
It comes from HeyGen Video. Mixer AI offers it next to other models and bills it from one coin balance.
Where can I launch HeyGen Video?

How do I see the exact price before launch?
Choose the settings in the Studio or Canvas: the price for them appears before the request is sent.
Does HeyGen Video need a prompt?

What if a generation fails?
A confirmed technical failure can be returned automatically or reviewed by support. Dissatisfaction with a creative result alone is not a technical failure. The conditions are in the offer.
What changes the price?
The coin rate per second depends on quality, mode and, for some models, sound. Multiply it by the billable duration. Where input video is charged, its duration also counts. The complete request total is rounded once.
Do I need a separate model subscription?
No. In Mixer AI, you top up one coin balance and use it for the tasks you need. You do not need a separate subscription to this model.
