AVIF to MP4 API - Convert AVIF to MP4 API: Pricing, Documentation

Authentication

Every request is authenticated with your Pixazo API key in the Ocp-Apim-Subscription-Key header — the same key across every Pixazo endpoint.

AVIF to MP4 generate request

AVIF gives excellent compression for the web but has thin support outside the browser, and almost none in video tooling. The AVIF to MP4 API sidesteps that: it decodes your AVIF, holds it for the duration you choose, and encodes a silent H.264/yuv420p MP4 with even dimensions that opens anywhere, downscaled to fit within 1920x1920 if larger and never upscaled if smaller. Transparency is flattened, since H.264 4:2:0 has no alpha channel. There is no motion, no prompt and no model behind it — it is a container change, priced flat at $0.002 per clip.

Endpoint: POST https://gateway.pixazo.ai/media-tools/v1/image-to-video

Request Code

curl -X POST 'https://gateway.pixazo.ai/media-tools/v1/image-to-video' \
  -H 'Ocp-Apim-Subscription-Key: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"image_url":"https://example.com/input.avif","duration_seconds":5}'

Output

{
  "request_id": "req_9f3c1a7b2e",
  "status": "QUEUED",
  "polling_url": "https://gateway.pixazo.ai/v2/requests/status/req_9f3c1a7b2e"
}

Webhook (Optional)

Instead of polling, include a webhook_url in the request body and Pixazo will POST the completed job payload to that URL when the conversion finishes. The webhook body is identical to the completed-status response shown under Retrieving Results.

The submit call returns one of the HTTP status codes below. A 202 means the job was accepted — everything else is an error you should handle.
