Parameters

Field	Type	Default	Allowed	What it does
`video_url`Required	`string`	—	—	The clip to restore, 3 to 60 seconds long. Length, framing and the audio track are kept; clips outside that range are rejected before any charge.
`resolution`Optional	`string`	`1080p`	720p, 1080p, 2k, 4k	Output tier: a pixel budget with the clip's aspect ratio kept, so a 624x360 clip at 1080p comes back at 1896x1094. Sets the per-second rate.

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.
