API Docs

Automated Tier Routing

Our engine analyzes job metadata in real-time. It automatically routes simple 1:1 transcodes to Standard while escalating complex multi-output AI jobs to Premium.

Smart Multiplexing

Avoid redundant encoding. We transmux compatible streams into MP4, HLS, or MPEG-DASH, with an encoded fallback when stream copy is incompatible.

Content Moderation

Premium safety checks for sexual, violent, and dangerous content, with observational report mode or fail-closed block mode before transcoding.

Quickstart

From media URL to finished output.

MediaRuntime is asynchronous. Submitting a job returns QUEUED immediately, and finished outputs arrive later on your signed webhook.

1
Provide a fetchable source URL
Use a public URL or a time-limited signed read URL from storage you already use.
2
Queue the media job
Send the source URL in source with the output presets you want back.
3
Handle the terminal webhook
Persist job_id, verify the signed event, and consume the returned output bundle.
