# H3 Max App FAQ

## Can I start with my own image?

Yes. Use a PNG, JPG or WebP opening frame, up to 2 MB each. Studio can retain up to four references in a project; the selected model determines how many are used in a render.

## How do I sign in?

Use Google via [Login](https://h3maxapp.com/sign-in). Account and project pages require authentication.

## When are credits used?

Credits are reserved when you approve generation. Unbilled failures return those credits. If the final charge is being reconciled, credits remain reserved until it is confirmed.

## How do annual plans work?

Pay once for the year, then receive credits each month. Unused monthly credits expire at the next allocation. See [pricing](https://h3maxapp.com/agents/pricing.md) for amounts and credit packs.

## Can I save and download?

Save your project in Studio. Download completed videos from Studio or your Library while signed in. Your projects and saved videos are private by default.

## Is this real-time streaming?

No. Videos are generated as individual clips. Studio shows generation progress.

## Can a bot call a public generation API?

These documents support reading and comparing the product. They do not provide a public developer generation API or an MCP server. Creating videos and purchasing credits use the signed-in product workflow with explicit approval.

## Where can I get help?

Email support@h3maxapp.com or use the signed-in support ticket page. See the [terms](https://h3maxapp.com/terms-of-service) and [privacy policy](https://h3maxapp.com/privacy-policy).
