Processing Time
Video Preview is a time intensive process. First time requests will return 423 for a few minutes until the video is fully processed. Either poll the URL until you receive a video response or check again after a few minutes to see the generated preview.
Defines the total length of the AI-generated video preview when video-preview=true is set. The value is specified in seconds.
When not specified, the default preview duration is 6 seconds.
