Render Request

curl-example.sh

curl -X POST https://render-api.chillin.online/render/v1 \
-H "Accept: application/json" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d @request.json

Note: Our rendering requests are processed async. After submitting a request, you will immediately receive a response containing a render_id, which can be used to query the rendering status and results.

Prop	Type	Required	Example	Value Range	Description
compositeWidth	number	true	1920	720 - 3840	The width of the composite.
compositeHeight	number	true	1080	720 - 3840	The height of the composite.
fps	number	true	30	15 - 60	The frame rate of the composite.
projectData	object	true	-	-	The project data. Can be exported from the editor.

Note: The compositeWidth and compositeHeight can differ from the width and height specified in projectData. However, the aspect ratio of compositeWidth to compositeHeight must remain consistent with the aspect ratio of projectData.width to projectData.height.

This design allows the same video project to be exported in different resolutions while maintaining the original aspect ratio.
