Script to video

POST
https://ext.videogen.io/v1/script-to-video
First, generate the AI text-to-speech and corresponding background footage. Once the video is created, an apiFileId will be returned. You can then use this apiFileId with the GET /get-file endpoint to check the export status of the video. The export process typically takes about the same time as the video's duration.
Alternatively, you can provide a webhook URL to automatically receive the export status, eliminating the need to manually poll the /get-file endpoint.
