Online beta limits
Use your own content or content you have permission to export. The studio supports self-contained HTML and CSS keyframe animations.
Animation settings
- HTML files: up to 120,000 UTF-8 bytes.
- Duration: 1–12 seconds. Frame rate: 12, 24 or 30 FPS, up to 360 frames.
- Dimensions: even numbers from 256 to 1920, up to 2,073,600 pixels.
- MP4 / H.264 video or a PNG of the selected frame. No audio.
- External images, fonts, links, CSS imports, scripts and website URL recording are not supported.
Free trial and account credits
Each anonymous browser identity receives three successful exports, shared between MP4 and PNG. Waiting or running jobs reserve an export; failed and cancelled jobs release it. Signing in carries over prior anonymous use instead of granting three more exports. Signed-in accounts share trial use, purchase records and paid credits across devices. Credit purchases are not available yet.
Shared export capacity
The online beta runs one renderer at a time, with up to five waiting jobs. Export submissions are limited to five per minute and thirty per day per network identifier. This network-based limit can affect people sharing a connection.
The initial service-wide allowance is up to 1,000 admitted jobs per calendar month. PNG exports, cancelled jobs and failed jobs count toward this allowance. Capacity may be temporarily unavailable when the queue or allowance is full.
Processing and downloads
A render has a 180-second processing timeout. Cold starts and queue time can add waiting time. Exported files must be 32 MiB or smaller. Closing a tab does not cancel a job; use Cancel export.
Downloads expire 30 minutes after completion. Keep a local copy of files you need. Drafts restore code and settings, but do not restore expired downloads or interrupted server jobs.
Scope
Advanced browser effects and interactive transitions may differ from a real-time page. Review the completed video before using it. AI generation, audio, payments and URL recording are not part of this beta. The developer's local-only server has its own development limits.
