Parameters

Field	Type	Default	Allowed	What it does
`video_url`Required	`string`	—	—	The clip to process, 1 to 60 seconds long, as an MP4 link or upload. Length and audio are kept; clips outside that range are rejected before any charge.
`prompt`Optional	`string`	—	up to 2,000 characters	Optional description of the clip or of the look you want; leave empty to let the model infer it.
`resolution`Optional	`string`	`1080p`	720p, 1080p, 4k	Output tier; the clip's aspect ratio is kept. Sets the per-second rate.
`creativity_level`Optional	`string`	`low`	low, medium, high	How much new detail is invented: low stays closest to the source, high is the most creative. Does not change the price.

Example request

This request runs as it is; any field you leave out uses its default. Put your key in POPNOW_API_KEY first.

The example uses PopNow sample files in video_url. Replace them with your own public HTTPS links, uploads or saved assets.
