How do I generate an AI presenter video with Synthesia?

Short answer: You can create ai video in Synthesia by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Synthesia Create AI Video action to a workflow, map its 6 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Create AI Video.

What does the Create AI Video action do in Synthesia?
Renders a Synthesia video of an AI avatar reading your script in the chosen voice and background. Generation is asynchronous, so pair this with Get Video to poll until the download URL is ready.
What inputs does Create AI Video require?
Required: Script. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Synthesia returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does Create AI Video support batch operations?
Yes. Run Create AI Video inside a Loop node to process arrays. TinyCommand handles Synthesia's rate limits automatically so you don't have to throttle manually.
