Only the parameters that apply to ad-generator are shown. Set values on the left, copy the payload on the right.
source.promptrequiredWhat the video should be about: the AI writes the script. For music-to-video it is an optional creative brief for the visual storyline. For lyrics-to-video, a description of the song to write (10 to 500 characters). For song-ad, the ad to write: the product or its page, the audience and the outcome. For character-swap, optional instructions on top of the swap (an outfit, ...).
source.stylePromptVisual style instructions, separate from the content prompt (e.g. "dark mood", "pastel watercolor").
source.durationSecondsHint for the script length the AI writes, in seconds.
