API key authentication

Request body

video_uristring required

SDR source video in HTTPS URL or base64 data URI format. See Input Formats for supported formats and codecs.

Max frames (and max duration at 24 fps) depend on the input resolution tier — inputs are snapped to the smallest tier that fits by pixel count:

Input resolution tier	Max frames	Max duration (at 24 fps)
Up to 1080p (≤ 1920×1080)	181	~7 seconds
Up to 1440p (≤ 2560×1440)	101	~4 seconds
Up to 4K (≤ 3840×2160)	41	~2 seconds

The output video preserves the input video's resolution.
