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 run history shows the failed step with its input and the error message Synthesia returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.
Does Create AI Video support batch operations?
Run Create AI Video inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Synthesia's rate limits.
