Payment & Credit FAQ

How much does a 10-minute video cost?

If the video already has original subtitles: 100% free to view. If you enable AI bilingual translation: 1 credit (~$0.001). If you dub the entire video: 2–4 credits (~$0.002–$0.004). Once cached, replays are free forever!

Do credits expire?

Never. Your purchased credits remain in your balance until used, with zero expiration date.

Can I use these credits across other Axio extensions?

Yes! VidFlow shares the unified AxioAPI CreditWallet. Your balance works across VidFlow, DocFlow, and other Axio services.

Is there any recurring monthly subscription trap?

No. VidFlow is purely Pay-As-You-Go. You only top up when you want, with no recurring charges.
