Shotstack

Shotstack renders videos from JSON templates. Templates define timeline, clips, effects; Sources are media (images, video URLs). Rendering is async—submit and poll for status.

Data Model

• Templates — video templates; define timeline and assets.
• Sources — media sources (images, videos) for templates.
• Renders — render jobs; have status (queued, rendering, done, failed).

Gotchas

• Async rendering: Video renders are async. Submit render, poll status endpoint until complete, then fetch output URL.
• Rate limit: ~30 requests/minute; use delay between calls.
• Template format: Templates use Shotstack's JSON schema; validate before submitting.
